Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
	Description of Business

	Preparation of Condensed Consolidated Financial Statements
	The condensed consolidated financial statements included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and on the same basis as the audited consolidated financial statements included in our Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (“SEC”) for the year ended January 31, 2015. The condensed consolidated statements of operations, comprehensive income, stockholders’ equity, and cash flows for the periods ended April 30, 2015 and 2014, and the condensed consolidated balance sheet as of April 30, 2015, are not audited but reflect all adjustments that are of a normal recurring nature and that are considered necessary for a fair presentation of the results for the periods shown. The condensed consolidated balance sheet as of January 31, 2015 is derived from the audited consolidated financial statements presented in our Annual Report on Form 10-K for the year ended January 31, 2015. Certain information and disclosures normally included in annual consolidated financial statements have been omitted pursuant to the rules and regulations of the SEC. Because the condensed consolidated interim financial statements do not include all of the information and disclosures required by GAAP for a complete set of financial statements, they should be read in conjunction with the audited consolidated financial statements and notes included in our Annual Report on Form 10-K filed with the SEC for the year ended January 31, 2015. The results for interim periods are not necessarily indicative of a full year’s results.
	Principles of Consolidation
	The accompanying condensed consolidated financial statements include the accounts of Verint Systems Inc., our wholly owned subsidiaries, and a joint venture in which we hold a 50% equity interest.  This joint venture functions as a systems integrator for Asian markets and is a variable interest entity in which we are the primary beneficiary. The noncontrolling interest in this joint venture is reflected within stockholders’ equity on our condensed consolidated balance sheet, but separately from our equity. Investments in companies in which we have less than a 20% ownership interest and do not exercise significant influence are accounted for at cost.  We include the results of operations of acquired companies from the date of acquisition.  All significant intercompany transactions and balances are eliminated.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires our management to make estimates and assumptions, which may affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period.  Actual results could differ from those estimates.
	Significant Accounting Policies
	Our significant accounting policies are described in Note 1 to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended January 31, 2015. There were no material changes to our significant accounting policies during the three months ended April 30, 2015.
	Recent Accounting Pronouncements
	New Accounting Pronouncements Recently Adopted
	In April 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. ASU No. 2014-08 raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. It was effective for us on February 1, 2015. The adoption of this standard did not impact our condensed consolidated financial statements.
	In January 2015, the FASB issued ASU No. 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. ASU No. 2015-01 eliminates the concept of an extraordinary item from GAAP. As a result, an entity is no longer required to separately present an extraordinary item on its statement of operations, net of tax, after income from continuing operations or to disclose income taxes and net income per share data applicable to an extraordinary item. However, ASU No. 2015-01 still retains the presentation and disclosure guidance for items that are unusual in nature and occur infrequently. ASU No. 2015-01 was effective for us on February 1, 2015. The adoption of this standard did not impact our condensed consolidated financial statements.
	New Accounting Pronouncements Not Yet Effective
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). ASU No. 2014-09 supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific revenue recognition guidance throughout the Industry Topics of the Accounting Standards Codification. Additionally, this update supersedes some cost guidance included in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. As currently issued, this guidance is effective for the first interim period within annual reporting periods beginning after December 15, 2016, and early adoption is not permitted; however, on April 1, 2015, the FASB voted to propose a one-year deferral to the effective date, but to permit entities to adopt one year earlier, at the original effective date. The proposal to defer the effective date will be subject to the FASB’s due process procedures, including a period for public comments. Entities may choose from two adoption methods, with certain practical expedients. We are currently reviewing this standard to assess the impact on our future condensed consolidated financial statements and evaluating the available adoption methods.
	In June 2014, the FASB issued ASU No. 2014-10, Development Stage Entities (Topic 915): Elimination of Certain Financial Reporting Requirements, Including an Amendment to Variable Interest Entities Guidance in Topic 810, Consolidation. ASU No. 2014-10 removes the financial reporting distinction between development stage entities and other reporting entities from GAAP and it eliminates an exception provided in the consolidation guidance for development stage enterprises. It is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, although early adoption is permitted. We are currently reviewing this standard to assess the impact on our future condensed consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-12, Compensation—Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period, which requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. ASU No. 2014-12 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, although early adoption is permitted. We are currently reviewing this standard to assess the impact on our future condensed consolidated financial statements.
	In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern. This ASU defines management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. The provisions of ASU No. 2014-15 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, although early adoption is permitted. The adoption of ASU No. 2014-15 is not expected to have a material effect on our future condensed consolidated financial statements.
	In April 2015, the FASB issued ASU No. 2015-03, Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. ASU No. 2015-03 requires an entity to present debt issuance costs related to a recognized debt liability in the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this update. The provisions of ASU No. 2015-03 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, although early adoption is permitted. When adopted, this guidance must be applied on a retrospective basis. We plan to adopt the provisions of ASU No. 2015-03 effective on February 1, 2016. As of April 30, 2015, we have $14.2 million of net deferred debt issuance costs which are reported within Other assets on our condensed consolidated balance sheet.
	In April 2015, the FASB issued ASU No. 2015-05, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Fees Paid in a Cloud Computing Arrangement. The amendments in this update provide guidance to customers about whether a cloud computing arrangement includes a software license. The provisions of ASU No. 2015-05 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, although early adoption is permitted. We are currently reviewing this standard to assess the impact on our future condensed consolidated financial statements.

	The 1.50% convertible senior notes ("Notes") will not impact the calculation of diluted net income per share unless the average price of our common stock, as calculated in accordance with the terms of the indenture governing the Notes, exceeds the conversion price of $64.46 per share. Likewise, diluted net income per share will not include any effect from the Warrants unless the average price of our common stock, as calculated under the terms of the Warrants, exceeds the exercise price of $75.00 per share. Further details regarding the Notes and the Warrants appear in Note 6, "Long-Term Debt".

All other bank deposits are included within cash and cash equivalents.
	As of April 30, 2015 and January 31, 2015, all of our available-for-sale investments had contractual maturities of less than one year. Gains and losses on sales of available-for-sale securities during the three months ended April 30, 2015 and 2014 were not significant.
	During the three months ended April 30, 2015 and 2014, proceeds from sales and maturities of available-for-sale securities were $5.5 million and $0.4 million, respectively.
	We believe that the investments we held at April 30, 2015 were not other-than-temporarily impaired. We held no available-for-sale securities with unrealized losses at April 30, 2015. We do not intend to sell our available-for-sale securities and it is not more likely than not that we will be required to sell them before recovery at par, which may be at maturity.

Business Combinations [Abstract]
BUSINESS COMBINATIONS	BUSINESS COMBINATIONS
	Three Months Ended April 30, 2015
	On February 12, 2015, we completed the acquisition of a business in the Europe, the Middle East and Africa (“EMEA”) region that is being integrated into our Enterprise Intelligence operating segment. This business combination was not material to our condensed consolidated financial statements.
	Year Ended January 31, 2015
	KANA Software, Inc.
	On February 3, 2014, we completed the acquisition of KANA Software, Inc. and its subsidiaries through the merger of KANA Software, Inc.'s parent holding company, Kay Technology Holdings, Inc. (collectively, "KANA"), with an indirect, wholly owned subsidiary of Verint, with Kay Technology Holdings, Inc. continuing as the surviving company and as our wholly owned subsidiary. The purchase price consisted of $542.4 million of cash paid at the closing, partially offset by $25.1 million of KANA’s cash received in the acquisition, and a $0.7 million post-closing purchase price adjustment, resulting in net cash consideration of $516.6 million.
	KANA, based in Sunnyvale, California and with global operations, is a leading provider of on-premises and cloud-based solutions which create differentiated, personalized, and integrated customer experiences for large enterprises and mid-market organizations. KANA has been substantially integrated into our Enterprise Intelligence operating segment.
	The merger consideration was funded by a combination of cash on hand, $300.0 million of incremental term loans incurred in connection with an amendment to our Credit Agreement, and $125.0 million of borrowings under our Revolving Credit Facility, further details for which appear in Note 6, "Long-Term Debt".
	Transaction and related costs directly related to the acquisition of KANA, consisting primarily of professional fees and integration expenses, were $2.6 million and $2.3 million for the three months ended April 30, 2015 and 2014, respectively, and were expensed as incurred. The vast majority of these expenses are included in selling, general and administrative expenses.
	UTX Technologies Limited
	On March 31, 2014, we completed the acquisition of all of the outstanding shares of UTX Technologies Limited (“UTX”), a provider of certain mobile device tracking solutions for security applications, from UTX Limited. UTX Limited was our supplier of these products to our Communications Intelligence operating segment prior to the acquisition. The purchase price consisted of $82.9 million of cash paid at closing, and $1.5 million paid subsequent to closing during the year ended January 31, 2015, upon UTX's achievement of certain performance targets. The acquisition date fair value of the contingent consideration was estimated to be $1.3 million.
	UTX is based in the EMEA region and has been integrated into our Communications Intelligence operating segment.
	Transaction and related costs directly related to the acquisition of UTX, consisting primarily of professional fees, integration expenses and related adjustments, were $0.2 million and $2.6 million for the three months ended April 30, 2015 and 2014, respectively, and were expensed as incurred and are included in selling, general and administrative expenses.
	As a result of the UTX acquisition, we recorded a $2.6 million charge for the impairment of certain capitalized software development costs during the three months ended April 30, 2014, reflecting strategy changes in certain product development initiatives. This charge is reflected within cost of product revenue.
	Other Business Combinations
	We completed two separate acquisitions of certain technologies and other assets for use in our Communications Intelligence operating segment on April 16, 2014 and January 15, 2015, respectively, in transactions that qualified as business combinations. These business combinations were not material to our condensed consolidated financial statements, individually or in the aggregate.
	Purchase Price Allocations
	As of January 31, 2015, the purchase price allocation for UTX was preliminary, subject to change as additional information became available during the measurement period (up to one year from the acquisition date). During the three months ended April 30, 2015, there were no changes to the purchase price allocation for UTX, which is now complete.
	Pro Forma Information
	The following table provides unaudited pro forma operating results for the three months ended April 30, 2014, as if KANA and UTX had been acquired on February 1, 2013. These unaudited pro forma results reflect certain adjustments related to these acquisitions, including amortization expense on finite-lived intangible assets acquired from KANA and UTX, interest expense and fees associated with additional long-term debt incurred to partially fund the acquisition of KANA, and adjustments to recognize the fair value of revenue associated with performance obligations assumed in the acquisition of KANA.
	For purposes of the following unaudited pro forma operating results, a $45.2 million income tax benefit recorded during the three months ended April 30, 2014 resulting from a reduction of valuation allowances associated from the acquisition of KANA is not reflected in the pro forma operating results for the three months ended April 30, 2014.
	The unaudited pro forma results do not include any operating efficiencies or potential cost savings which may result from these business combinations. Accordingly, such unaudited pro forma amounts are not necessarily indicative of the results that actually would have occurred had the acquisitions been completed on February 1, 2013, nor are they indicative of future operating results.

	For the three months ended April 30, 2015 and 2014, we recorded a charge of $0.1 million and a benefit of $0.2 million, respectively, within selling, general and administrative expenses for changes in the fair values of contingent consideration obligations associated with business combinations. The aggregate fair value of the remaining contingent consideration obligations associated with business combinations was $12.4 million at April 30, 2015.
	In connection with a business combination completed during the year ended January 31, 2012, we assumed approximately $5.2 million of long-term liabilities associated with uncertain tax positions of the acquired company. A corresponding indemnification asset of $5.2 million was also recorded, recognizing the selling shareholders’ contractual obligation to indemnify us for these pre-acquisition liabilities. As of April 30, 2015 and January 31, 2015, these liabilities were $1.3 million and $1.4 million, respectively, and were included within other liabilities. The corresponding indemnification assets as of April 30, 2015 and January 31, 2015 were $0.4 million and $0.4 million, respectively, and were included within other assets. There was no activity in these accounts during the three months ended April 30, 2015 and 2014. The carrying values of these assets and liabilities were impacted by foreign currency exchange rate fluctuations.

	1.50% Convertible Senior Notes
	On June 18, 2014, we issued $400.0 million in aggregate principal amount of 1.50% convertible senior notes ("Notes") due June 1, 2021, unless earlier converted by the holders pursuant to their terms. Net proceeds from the Notes after underwriting discounts were $391.9 million. The Notes pay interest in cash semiannually in arrears at a rate of 1.50% per annum.
	The Notes were issued concurrently with our issuance of 5,750,000 shares of common stock, the majority of the combined net proceeds of which were used to partially repay certain indebtedness under our Credit Agreement.
	The Notes are unsecured and rank senior in right of payment to our indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to our indebtedness that is not so subordinated; effectively subordinated in right of payment to any of our secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally subordinated to indebtedness and other liabilities of our subsidiaries.
	The Notes are convertible into, at our election, cash, shares of common stock, or a combination of both, subject to satisfaction of specified conditions and during specified periods, as described below. If converted, we currently intend to pay cash in respect of the principal amount of the Notes.
	The conversion price of the Notes at any time is equal to $1,000 divided by the then-applicable conversion rate. The Notes have a conversion rate of 15.5129 shares of common stock per $1,000 principal amount of Notes, which represents an effective conversion price of approximately $64.46 per share of common stock and would result in the issuance of approximately 6,205,000 shares if all of the Notes were converted. The conversion rate has not changed since issuance of the Notes, although throughout the term of the Notes, the conversion rate may be adjusted upon the occurrence of certain events.
	Holders may surrender their Notes for conversion at any time prior to the close of business on the business day immediately preceding December 1, 2020, only under the following circumstances:
	•	during any calendar quarter commencing after the calendar quarter which ended on September 30, 2014, if the closing sale price of our common stock, for at least 20 trading days (whether or not consecutive) in the period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter, is more than 130% of the conversion price of the Notes in effect on each applicable trading day;
	•	during the ten consecutive trading-day period following any five consecutive trading-day period in which the trading price for the Notes for each such trading day was less than 98% of the closing sale price of our common stock on such date multiplied by the then-current conversion rate; or
	•	upon the occurrence of specified corporate events, as described in the indenture governing the Notes, such as a consolidation, merger, or binding share exchange.
	On or after December 1, 2020 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may surrender their Notes for conversion regardless of whether any of the foregoing conditions have been satisfied.
	As of April 30, 2015, the Notes were not convertible.
	In accordance with accounting guidance for convertible debt with a cash conversion option, we separately accounted for the debt and equity components of the Notes in a manner that reflected our estimated nonconvertible debt borrowing rate. We estimated the carrying amount of the debt component of the Notes to be $319.9 million at the issuance date, assuming a 5.00% non-convertible borrowing rate. The carrying amount of the equity component was determined to be approximately $80.1 million by deducting the carrying amount of the debt component from the principal amount of the Notes, and was recorded as an increase to additional paid-in capital. The excess of the principal amount of the debt component over its carrying amount (the “debt discount”) is being amortized as interest expense over the term of the Notes using the effective interest method. The equity component is not remeasured as long as it continues to meet the conditions for equity classification.
	We allocated transaction costs related to the issuance of the Notes, including underwriting discounts, of $7.6 million and $1.9 million to the debt and equity components, respectively. Issuance costs attributable to the debt component were recorded within other assets and are being amortized as interest expense over the term of the Notes, and issuance costs attributable to the equity component were netted with the equity component in additional paid-in capital. The carrying amount of the equity component, net of issuance costs, was $78.2 million at April 30, 2015. Including the impact of the debt discount and related deferred debt issuance costs, the effective interest rate on the Notes was approximately 5.29% at April 30, 2015.
	Based on the closing market price of our common stock on April 30, 2015, the if-converted value of the Notes was less than the aggregate principal amount of the Notes.
	Note Hedges and Warrants
	Concurrently with the issuance of the Notes, we entered into convertible note hedge transactions (the “Note Hedges”) and sold warrants (the “Warrants”). The combination of the Note Hedges and the Warrants serves to increase the effective initial conversion price for the Notes to $75.00 per share. The Note Hedges and Warrants are each separate instruments from the Notes.
	Note Hedges
	Pursuant to the Note Hedges, we purchased call options on our common stock, under which we have the right to acquire from the counterparties up to approximately 6,205,000 shares of our common stock, subject to customary anti-dilution adjustments, at a price of $64.46, which equals the initial conversion price of the Notes. Our exercise rights under the Note Hedges generally trigger upon conversion of the Notes and the Note Hedges terminate upon maturity of the Notes, or the first day the Notes are no longer outstanding. The Note Hedges may be settled in cash, shares of our common stock, or a combination thereof, at our option, and are intended to reduce our exposure to potential dilution upon conversion of the Notes. We paid $60.8 million for the Note Hedges, which was recorded as a reduction to additional paid-in capital. As of April 30, 2015, we had not purchased any shares of our common stock under the Note Hedges.
	Warrants
	We sold the Warrants to several counterparties. The Warrants provide the counterparties rights to acquire from us up to approximately 6,205,000 shares of our common stock at a price of $75.00 per share. The Warrants expire incrementally on a series of expiration dates beginning in August 2021. At expiration, if the market price per share of our common stock exceeds the strike price of the Warrants, we will be obligated to issue shares of our common stock having a value equal to such excess. The Warrants could have a dilutive effect on net income per share to the extent that the market value of our common stock exceeds the strike price of the Warrants. Proceeds from the sale of the Warrants were $45.2 million and were recorded as additional paid-in capital. As of April 30, 2015, no Warrants had been exercised and all Warrants remained outstanding.
	The Note Hedges and Warrants both meet the requirements for classification within stockholders’ equity, and their respective fair values are not remeasured and adjusted as long as these instruments continue to qualify for stockholders’ equity classification.
	Credit Agreement
	Background
	In April 2011, we entered into a credit agreement with our lenders, which was amended and restated on March 6, 2013, and further amended on February 3, 2014, March 7, 2014, and June 18, 2014 (the “Credit Agreement"). The Credit Agreement, as amended and restated, provides for senior secured credit facilities, comprised of $943.5 million of term loans, of which $300.0 million was borrowed in February 2014 (the “February 2014 Term Loans”) and $643.5 million was borrowed in March 2014 (the “March 2014 Term Loans”), all of which matures in September 2019, and a $300.0 million revolving credit facility maturing in September 2018 (the “Revolving Credit Facility”), subject to increase (up to a maximum increase of $300.0 million) and reduction from time to time.
	At April 30, 2015, $130.7 million and $280.4 million of borrowings were outstanding under the February 2014 Term Loans and March 2014 Term Loans, respectively, and there were no outstanding borrowings under the Revolving Credit Facility.
	As further described below, on March 7, 2014, $643.5 million of term loans previously borrowed under the Credit Agreement
	(the "March 2013 Term Loans") were extinguished and replaced with the March 2014 Term Loans, and the basis for determining the interest rate on borrowings under the Revolving Credit Facility was also amended.
	From March 6, 2013 through March 6, 2014, the March 2013 Term Loans and borrowings under the Revolving Credit Facility, if any, incurred interest, payable quarterly or, in the case of Eurodollar loans with an interest period of three months or shorter, at the end of any interest period, at a per annum rate of, at our election:
	•	in the case of Eurodollar loans, the Adjusted LIBO Rate plus 3.00% (or, if our corporate credit ratings are BB- and Ba3 or better, 2.75%). The Adjusted LIBO Rate is the greater of (i) 1.00% per annum and (ii) the product of the LIBO Rate and Statutory Reserves (both as defined in the Credit Agreement), and
	•	in the case of Base Rate loans, the Base Rate plus 2.00% (or, if our corporate credit ratings are BB- and Ba3 or better, 1.75%). The Base Rate is the greatest of (i) the administrative agent's prime rate, (ii) the Federal Funds Effective Rate (as defined in the Credit Agreement) plus 0.50% and (iii) the Adjusted LIBO Rate for a one-month interest period plus 1.00%.
	Debt issuance costs incurred in connection with the Credit Agreement, as well as costs incurred for debt modifications, are deferred. These costs are amortized as adjustments to interest expense over the remaining contractual life of the associated borrowings. Original issuance discounts on term loans are also amortized as adjustments to interest expense over the remaining contractual life of the associated term loans. Upon early retirement of debt, the associated deferred debt issuance costs and unamortized original issuance discount, if any, are written off as a loss on early retirement of debt.
	We are required to pay a commitment fee equal to 0.50% per annum of the undrawn portion on the Revolving Credit Facility, payable quarterly, and customary administrative agent and letter of credit fees.
	2014 Amendments to Credit Agreement
	During the year ended January 31, 2015, we entered into five separate amendments to the Credit Agreement as described below.
	On February 3, 2014, in connection with the acquisition of KANA, we borrowed $125.0 million under the Revolving Credit Facility and entered into Amendment No. 1 pursuant to which, on such date, we incurred the February 2014 Term Loans of $300.0 million, maturing in September 2019. The net proceeds of these borrowings were used to fund a portion of the KANA purchase price.
	The February 2014 Term Loans bear interest, payable quarterly or, in the case of Eurodollar loans with an interest period of three months or less, at the end of the applicable interest period, at a per annum rate of, at our election:
	•	in the case of Eurodollar loans, the Adjusted LIBO Rate plus 2.75%. The Adjusted LIBO Rate is the greater of (i) 0.75% per annum and (ii) the product of (x) the LIBO Rate and (y) Statutory Reserves (both as defined in the Credit Agreement), and
	•	in the case of Base Rate loans, the Base Rate plus 1.75%. The Base Rate is the greatest of (i) the administrative agent’s prime rate, (ii) the Federal Funds Effective Rate (as defined in the Credit Agreement) plus 0.50% and (iii) the Adjusted LIBO Rate for a one-month interest period plus 1.00%.
	We incurred debt issuance costs of approximately $7.1 million associated with the February 2014 Term Loans, which were deferred and classified within other assets. The February 2014 Term Loans were also subject to an original issuance discount of 0.25%, or $0.8 million.
	On February 3, 2014, we also entered into Amendment No. 2 to, among other things, (i) permit us to increase the permitted amount of additional incremental term loans and revolving credit commitments under the Credit Agreement (beyond the February 2014 Term Loans borrowed under Amendment No. 1) by up to, in the aggregate, $200.0 million plus an additional amount such that the First Lien Leverage Ratio (as defined in Amendment No. 2) would not exceed the specified maximum ratio set forth therein, (ii) increase the size of certain negative covenant basket carve-outs, (iii) permit us to issue Permitted Convertible Indebtedness (as defined in Amendment No. 2), and (iv) permit us to refinance all or a portion of any existing class of term loans under the Credit Agreement with replacement term loans.
	On February 3, 2014, we also entered into Amendment No. 3 to extend by one year, to January 31, 2016, the step-down date of the leverage ratio covenant applicable to our Revolving Credit Facility and, subject to the effectiveness of Amendment No. 4 (as described below), reprice the interest rate applicable to borrowings under the Revolving Credit Facility to the interest rate applicable to the February 2014 Term Loans.
	On March 7, 2014, we entered into Amendment No. 4 to refinance all $643.5 million of outstanding March 2013 Term Loans at that date with the March 2014 Term Loans of $643.5 million, maturing in September 2019. The provisions for determining the interest rate on the March 2014 Term Loans are identical to such provisions for the February 2014 Term Loans. The repricing of the interest rate applicable to borrowings under the Revolving Credit Facility contemplated by Amendment No. 3 became effective on March 7, 2014, upon the effectiveness of Amendment No. 4.
	The refinancing of the March 2013 Term Loans with the proceeds of the March 2014 Term Loans pursuant to Amendment No. 4 was accounted for as an early retirement of the March 2013 Term Loans and, as a result, $4.3 million of unamortized deferred debt issuance costs and $2.8 million of unamortized discount associated with the March 2013 Term Loans as of the March 7, 2014 effective date of Amendment No. 4 were written off as a $7.1 million loss on early retirement of debt.
	As of April 30, 2015 and January 31, 2015, the interest rate on both the February 2014 Term Loans and the March 2014 Term Loans was 3.50%. Taking into account the impact of original issuance discounts, if any, and related deferred debt issuance costs, the effective interest rates on the February 2014 Term Loans and March 2014 Term Loans were approximately 4.03% and 3.58%, respectively, at April 30, 2015.
	We incurred $2.4 million of debt issuance costs in consideration of Amendment No. 4. There was no original issuance discount on the March 2014 Term Loans.
On June 18, 2014, we entered into Amendment No. 5, which increased the commitments under the Revolving Credit Facility to $300.0 million and extended the termination of the Revolving Credit Facility to September 2018.
Early Partial Retirement of Term Loans - June 2014
On June 18, 2014, we utilized the majority of the combined net proceeds from the issuance of the Notes and the concurrent issuance of 5,750,000 shares of common stock to retire $530.0 million of the February 2014 Term Loans and March 2014 Term Loans, and all $106.0 million of then-outstanding borrowings under the Revolving Credit Facility. As a result, $3.8 million and $1.3 million of deferred debt issuance costs associated with the February 2014 Term Loans and March 2014 Term Loans, respectively, and $0.4 million of unamortized discount associated with the February 2014 Term Loans, were written off as a $5.5 million loss on early retirement of debt.
Borrowings Under Revolving Credit Facility
There were no borrowings under the Revolving Credit Facility at April 30, 2015 and January 31, 2015.
Other Provisions of the Credit Agreement
The Credit Agreement contains certain customary affirmative and negative covenants for credit facilities of this type, which include limitations on us and our subsidiaries with respect to indebtedness, liens, nature of business, investments and loans, distributions, acquisitions, dispositions of assets, sale-leaseback transactions and transactions with affiliates. The Revolving Credit Facility also contains a financial covenant that requires us to maintain a ratio of Consolidated Total Debt to Consolidated EBITDA (each as defined in the Credit Agreement) of no greater than 5.00 to 1 until January 31, 2016 (as amended on February 3, 2014 by Amendment No. 3, as described above) and no greater than 4.50 to 1 thereafter (the "Leverage Ratio Covenant"). The limitations imposed by the covenants are subject to certain exceptions as detailed in the Credit Agreement.
Future Principal Payments on Term Loans
Prior to June 2014, we were required to make quarterly principal payments on the February 2014 Term Loans and March 2014 Term Loans of $0.8 million and $1.6 million, respectively, through August 1, 2019, with the remaining balances due in September 2019. Following the partial retirements of the February 2014 Term Loans and March 2014 Term Loans in June 2014, future scheduled principal payments on the February 2014 Term Loans and March 2014 Term Loans as of April 30, 2015 were as follows:

INCOME_TAXES

INCOME TAXES	3 Months Ended
	Apr. 30, 2015
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES
	Our interim provision (benefit) for income taxes is measured using an estimated annual effective tax rate, adjusted for discrete items that occur within the periods presented.
	For the three months ended April 30, 2015, we recorded an income tax provision of $0.9 million on pre-tax income of $1.7 million, which represented an effective income tax rate of 56.4%. The income tax provision does not include income tax benefits on losses incurred by certain domestic and foreign operations where we maintain valuation allowances and is mainly the result of the activities of profitable jurisdictions. In addition, following the receipt of a tax ruling in a foreign jurisdiction, we reorganized certain operations within the foreign jurisdiction, resulting in a discrete income tax benefit of $3.0 million. Our pre-tax income in profitable jurisdictions, where we record tax provisions, was slightly higher than the pre-tax losses in domestic and foreign jurisdictions where we maintain valuation allowances and do not record tax benefits.
	For the three months ended April 30, 2014, we recorded an income tax benefit of $42.1 million on a pre-tax loss of $13.3 million, which represented an effective income tax benefit rate of 317.2%. The income tax benefit was primarily attributable to the release of $45.2 million of Verint valuation allowances. We maintain valuation allowances on our net U.S. deferred income tax assets related to federal and certain state jurisdictions.  In connection with the acquisition of KANA, we recorded deferred income tax liabilities primarily attributable to acquired intangible assets to the extent the amortization will not be deductible for tax purposes. Under accounting guidelines, because the amortization of the intangible assets in future periods provides a source of taxable income, we expect to realize a portion of our existing deferred income tax assets. As such, we have reduced the valuation allowance recorded on our deferred income tax assets to the extent of the deferred income tax liabilities recorded.  Because the valuation allowance related to existing Verint deferred income tax assets, the impact of the release was reflected as a discrete income tax benefit and not as a component of the KANA acquisition accounting. The effective income tax rate was also affected by the mix and levels of income and losses among taxing jurisdictions. Pre-tax income in our profitable jurisdictions, where we recorded tax provisions, was less than our domestic losses where we maintain valuation allowances and did not record the related tax benefits. Excluding the income tax benefit attributable to the valuation allowance release, the result was an income tax provision of $3.1 million on a pre-tax loss $13.3 million, resulting in a negative effective tax rate of 23.2%.
	As required by the authoritative guidance on accounting for income taxes, we evaluate the realizability of deferred income tax assets on a jurisdictional basis at each reporting date.  Accounting guidance for income taxes requires that a valuation allowance be established when it is more-likely-than-not that all or a portion of the deferred income tax assets will not be realized.  In circumstances where there is sufficient negative evidence indicating that the deferred income tax assets are not more-likely-than-not realizable, we establish a valuation allowance.  We determined that there is sufficient negative evidence to maintain the valuation allowances against our federal and certain state and foreign deferred income tax assets as a result of historical losses in the most recent three-year period in the U.S. and in certain foreign jurisdictions.  We intend to maintain valuation allowances until sufficient positive evidence exists to support a reversal.
	We had unrecognized tax benefits of $163.3 million and $159.6 million (excluding interest and penalties) as of April 30, 2015 and January 31, 2015, respectively.  The accrued liability for interest and penalties was $10.8 million and $10.9 million at April 30, 2015 and January 31, 2015, respectively.  Interest and penalties are recorded as a component of the provision for income taxes in our condensed consolidated statements of operations.  As of April 30, 2015 and January 31, 2015, the total amount of unrecognized tax benefits that, if recognized, would impact our effective tax rate were approximately $156.7 million and $153.1 million, respectively.  We regularly assess the adequacy of our provisions for income tax contingencies in accordance with the applicable authoritative guidance on accounting for income taxes.  As a result, we may adjust the reserves for unrecognized tax benefits for the impact of new facts and developments, such as changes to interpretations of relevant tax law, assessments from taxing authorities, settlements with taxing authorities, and lapses of statutes of limitation.  Further, we believe that it is reasonably possible that the total amount of unrecognized tax benefits at April 30, 2015 could decrease by approximately $4.7 million in the next twelve months as a result of settlement of certain tax audits or lapses of statutes of limitation.  Such decreases may involve the payment of additional taxes, the adjustment of deferred income taxes including the need for additional valuation allowances, and the recognition of tax benefits.  Our income tax returns are subject to ongoing tax examinations in several jurisdictions in which we operate.  We also believe that it is reasonably possible that new issues may be raised by tax authorities or developments in tax audits may occur which would require increases or decreases to the balance of reserves for unrecognized tax benefits; however, an estimate of such changes cannot reasonably be made.

FAIR_VALUE_MEASUREMENTS

FAIR VALUE MEASUREMENTS	3 Months Ended
	Apr. 30, 2015
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS
	Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required to be recorded at fair value, we consider the principal or most advantageous market in which we would transact and consider assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance.
	Accounting guidance establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. An instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. This fair value hierarchy consists of three levels of inputs that may be used to measure fair value:
	•Level 1:  quoted prices in active markets for identical assets or liabilities;
	•	Level 2:  inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; or
	•	Level 3:  unobservable inputs that are supported by little or no market activity.
	We review the fair value hierarchy classification of our applicable assets and liabilities at each reporting period. Changes in the observability of valuation inputs may result in transfers within the fair value measurement hierarchy. We did not identify any transfers between levels of the fair value measurement hierarchy during the years ended April 30, 2015 and 2014.
	Assets and Liabilities Measured at Fair Value on a Recurring Basis
	Our assets and liabilities measured at fair value on a recurring basis consisted of the following as of April 30, 2015 and 2014:

	Fair value measurement at end of period		$	12,400		$	19,119
	Our estimated liability for contingent consideration represents potential payments of additional consideration for business combinations, payable if certain defined performance goals are achieved. Changes in fair value of contingent consideration are recorded in the condensed consolidated statements of operations within selling, general and administrative expenses.
	Fair Value Measurements
	Money Market Funds - We value our money market funds using quoted active market prices for such funds.
	Short-term Investments and Commercial Paper - The fair values of short-term investments, as well as commercial paper classified as cash equivalents, are estimated using observable market prices for identical securities that are traded in less-active markets, if available. When observable market prices for identical securities are not available, we value these short-term investments using non-binding market price quotes from brokers which we review for reasonableness using observable market data; quoted market prices for similar instruments; or pricing models, such as a discounted cash flow model.
	Foreign Currency Forward Contracts - The estimated fair value of foreign currency forward contracts is based on quotes received from the counterparties thereto. These quotes are reviewed for reasonableness by discounting the future estimated cash flows under the contracts, considering the terms and maturities of the contracts and market exchange rates using readily observable market prices for similar contracts.
	Contingent Consideration - Business Combinations - The fair value of the contingent consideration related to business combinations is estimated using a probability-adjusted discounted cash flow model. These fair value measurements are based on significant inputs not observable in the market. The key internally developed assumptions used in these models are discount rates and the probabilities assigned to the milestones to be achieved. We remeasure the fair value of the contingent consideration at each reporting period, and any changes in fair value resulting from either the passage of time or events occurring after the acquisition date, such as changes in discount rates, or in the expectations of achieving the performance targets, are recorded within selling, general, and administrative expenses. Increases or decreases in discount rates would have inverse impacts on the related fair value measurements, while favorable or unfavorable changes in expectations of achieving performance targets would result in corresponding increases or decreases in the related fair value measurements. We utilized discount rates ranging from 2.0% to 41.7% in our calculations of the estimated fair values of our contingent consideration liabilities as of April 30, 2015. We utilized discount rates ranging from 2.0% to 41.7% in our calculations of the estimated fair values of our contingent consideration liabilities as of January 31, 2015.
	Other Financial Instruments
	The carrying amounts of accounts receivable, accounts payable, and accrued liabilities and other current liabilities approximate fair value due to their short maturities.
	The estimated fair values of our term loan borrowings were $413 million and $409 million at April 30, 2015 and January 31, 2015, respectively. The estimated fair values of the term loans are based upon indicative bid and ask prices as determined by the agent responsible for the syndication of our term loans. We consider these inputs to be within Level 3 of the fair value hierarchy because we cannot reasonably observe activity in the limited market in which participations in our term loans are traded. The indicative prices provided to us as at each of April 30, 2015 and January 31, 2015 did not significantly differ from par value. The estimated fair value of our revolving credit borrowings, if any, is based upon indicative market values provided by one of our lenders. We had no revolving credit borrowings at April 30, 2015 and January 31, 2015.
	The estimated fair values of our Notes were approximately $468 million and $427 million at April 30, 2015 and January 31, 2015, respectively. The estimated fair values of the Notes are determined based on quoted bid and ask prices in the over-the-counter market in which the Notes trade. We consider these inputs to be within Level 2 of the fair value hierarchy.
	Assets and Liabilities Not Measured at Fair Value on a Recurring Basis
	In addition to assets and liabilities that are measured at fair value on a recurring basis, we also measure certain assets and liabilities at fair value on a nonrecurring basis. Our non-financial assets, including goodwill, intangible assets and property, plant and equipment, are measured at fair value when there is an indication of impairment and the carrying amount exceeds the asset’s projected undiscounted cash flows. These assets are recorded at fair value only when an impairment charge is recognized.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS
	Our primary objective for holding derivative financial instruments is to manage foreign currency exchange rate risk and interest rate risk, when deemed appropriate. We enter into these contracts in the normal course of business to mitigate risks and not for speculative purposes.
	Foreign Currency Forward Contracts
	Under our risk management strategy, we periodically use foreign currency forward contracts to manage our short-term exposures to fluctuations in operational cash flows resulting from changes in foreign currency exchange rates. These cash flow exposures result from portions of our forecasted operating expenses, primarily compensation and related expenses, which are transacted in currencies other than the U.S. dollar, primarily the Israeli shekel and the Canadian dollar. We also periodically utilize foreign currency forward contracts to manage exposures resulting from forecasted customer collections to be remitted in currencies other than the applicable functional currency, and exposures from cash, cash equivalents and short-term investments denominated in currencies other than the applicable functional currency. Our joint venture, which has a Singapore dollar functional currency, also utilizes foreign exchange forward contracts to manage its exposure to exchange rate fluctuations related to settlements of liabilities denominated in U.S. dollars. These foreign currency forward contracts generally have maturities of no longer than twelve months, although occasionally we will execute a contract that extends beyond twelve months, depending upon the nature of the underlying risk.
	Notional Amounts of Derivative Financial Instruments
	Our outstanding derivative financial instruments consisted only of foreign currency forward contracts with notional amounts of $153.3 million and $156.8 million as of April 30, 2015 and January 31, 2015, respectively.
	Fair Values of Derivative Financial Instruments
	The fair values of our derivative financial instruments and their classifications in our condensed consolidated balance sheets as of April 30, 2015 and January 31, 2015 were as follows:

	There were no gains or losses from ineffectiveness of these cash flow hedges recorded for the three months ended April 30, 2015 and 2014. All of the foreign currency forward contracts underlying the $3.5 million of net unrealized losses recorded in our accumulated other comprehensive loss at April 30, 2015 mature within twelve months, and therefore we expect all such losses to be reclassified into earnings within the next twelve months.

	Total stock-based compensation expense by classification was as follows for the three months ended April 30, 2015, and 2014:
		Three Months Ended
		April 30,
	(in thousands)	2015			2014
	Equity-classified awards	$	13,100		$	10,228
	Liability-classified awards	1,750			1,261
	Total stock-based compensation expense	$	14,850		$	11,489
	The increase in stock-based compensation expense during the three months ended April 30, 2015, compared to the corresponding prior-year period, resulted primarily from the combination of an increase in the number of outstanding restricted stock units ("RSU's"), higher expenses associated with performance-based RSU's, a general increase in the price of our common stock, which is used to determine the grant-date fair value of an RSU, and a bonus share program, further details for which appear below under "Bonus Share Program".
	Awards under our stock bonus program are accounted for as liability-classified awards, because the obligations are based predominantly on fixed monetary amounts that are generally known at inception of the obligation, to be settled with a variable number of shares of our common stock. Our other liability-classified awards include our phantom stock awards and certain discretionary bonuses. Upon settlement of other liability-classified awards with equity, compensation expense associated with those awards is reported within equity-classified awards in the table above.
	Restricted Stock Units
	We periodically award restricted stock units to our directors, officers, and other employees. These awards contain various vesting conditions and are subject to certain restrictions and forfeiture provisions prior to vesting.
	The following table summarizes restricted stock unit activity and related information for the three months ended April 30, 2015:
	(in thousands, except per share data)	Number of RSU's		Weighted-Average Grant Date Fair Value
	RSU's outstanding, January 31, 2015	2,545		$	40.96
	RSU's granted	1,424		$	64.77
	RSU's released	(447	)	$	40.67
	RSU's forfeited	(117	)	$	47.21
	RSU's outstanding, April 30, 2015	3,405		$	50.74
	Substantially all of the restricted stock units granted during the year ended January 31, 2013 included a provision which allows those awards to be settled with cash payments upon vesting, rather than with delivery of common stock, at the discretion of our board of directors. As of April 30, 2015, for such awards that remain outstanding, settlement of these awards with cash payments was not considered probable, and therefore these awards have been accounted for as equity-classified awards.
	With respect of our Stock Bonus Program, activity presented in the table above only includes shares earned and released in consideration of the discount provided under that program. Consistent with the provisions of the plan under which such shares are issued, other shares issued under the Stock Bonus Program are not included in the table above because they do not reduce available plan capacity. Further details appear below under “Stock Bonus Program”.
	As of April 30, 2015, there was approximately $125.6 million of total unrecognized compensation expense, net of estimated forfeitures, related to unvested restricted stock units, which is expected to be recognized over a weighted-average period of 2.1 years. The unrecognized compensation expense does not include compensation expense related to shares for which a grant date has been established but the requisite service period has not begun.
	Stock Bonus Program
	In September 2011, our board of directors approved a stock bonus program under which eligible employees may receive a portion of their bonuses, otherwise payable in cash, in the form of discounted shares of our common stock. Executive officers have been eligible to participate in this program from and after the year ended January 31, 2014 to the extent that shares remained available for awards following the enrollment of all other participants. Shares awarded to executive officers with respect to the discount feature of the program are subject to a one-year vesting period. This program is subject to annual funding approval by our board of directors and an annual cap on the number of shares that can be issued. Subject to these limitations, the number of shares to be issued under the program for a given year is determined using a five-day trailing average price of our common stock when the awards are calculated, reduced by a discount to be determined by the board of directors each year (the "discount"). To the extent that this program is not funded in a given year or the number of shares of common stock needed to fully satisfy employee enrollment exceeds the annual cap, the applicable portion of the employee bonuses will generally revert to being paid in cash. Obligations under this program are accounted for as liabilities, because the obligations are based predominantly on fixed monetary amounts that are generally known at inception of the obligation, to be settled with a variable number of shares of common stock determined using a discounted average price of our common stock.
	For the year ended January 31, 2015, our board of directors approved up to 125,000 shares of common stock for awards under the program and a discount of 15% (the "2015 stock bonus program"). Awards earned under the 2015 stock bonus program are expected to be issued during the three months ended July 31, 2015.
	On March 19, 2015, our board of directors approved up to 125,000 shares of common stock, and a discount of 15%, for awards under our stock bonus program for the year ending January 31, 2016. Executive officers will be permitted to participate in this program for the year ending January 31, 2016, but only to the extent that shares remain available for awards following the enrollment of all other participants. Shares awarded to executive officers with respect to the 15% discount will be subject to a one-year vesting period.
	Bonus Share Program
	In February 2015, our board of directors authorized the use of shares of common stock available under our equity incentive plans to award up to approximately $4.7 million in bonuses in respect of performance during the year ended January 31, 2015 to employees other than executive officers, subject to certain limitations on the aggregate number of shares that may be issued. There is no discount feature associated with these bonus share awards. Similar to the accounting for the stock bonus program, obligations for these bonuses are accounted for as liabilities, because the obligations are based predominantly on fixed monetary amounts that are generally known, to be settled with a variable number of shares of common stock. Shares awarded in respect of the bonus share program period ended January 31, 2015 are expected to be issued during the three months ending July 31, 2015.
	In March 2015, our board of directors authorized the continuation of the bonus share program in respect of bonuses for the year ending January 31, 2016, and has approved up to 75,000 shares of common stock for awards under this program in respect of that period. Shares awarded in respect of the bonus share program period ended January 31, 2016 are expected to be issued during the first half of the year ending January 31, 2017.
	The combined accrued liabilities for the stock bonus program and the bonus share program were $9.7 million and $8.0 million at April 30, 2015 and January 31, 2015, respectively.
	Other Stock-Based Compensation Awards
	We periodically grant stock options, phantom stock, and restricted stock awards to our directors, officers, and other employees. Activity under these awards was not significant for the three months ended April 30, 2015 and 2014.
	Proposed New Stock-Based Compensation Plan
	On May 12, 2015, our board of directors approved a new equity incentive plan and the termination of our existing equity incentive plans, in each case, subject to the approval of such new equity incentive plan by our stockholders at our annual meeting of stockholders to be held on June 25, 2015. If our stockholders approve the adoption of the new equity incentive plan, effective on the date of such approval, no additional awards will be permitted under our existing equity incentive plans. Such approval will not have any effect on the settlement of awards that are outstanding as of the date of such approval.

	Legal Proceedings
	On March 26, 2009, legal actions were commenced by Ms. Orit Deutsch, a former employee of our subsidiary, Verint Systems Limited ("VSL"), against VSL in the Tel Aviv Regional Labor Court (Case Number 4186/09) (the “Deutsch Labor Action”) and against CTI in the Tel Aviv District Court (Case Number 1335/09) (the “Deutsch District Action”). In the Deutsch Labor Action, Ms. Deutsch filed a motion to approve a class action lawsuit on the grounds that she purports to represent a class of our employees and former employees who were granted Verint and CTI stock options and were allegedly damaged as a result of the suspension of option exercises during our previous extended filing delay period. In the Deutsch District Action, in addition to a small amount of individual damages, Ms. Deutsch is seeking to certify a class of plaintiffs who were allegedly damaged due to their inability to exercise Verint and CTI stock options as a result of alleged negligence by CTI in its financial reporting. The class certification motions do not specify an amount of damages. On February 8, 2010, the Deutsch Labor Action was dismissed for lack of material jurisdiction and was transferred to the Tel Aviv District Court and consolidated with the Deutsch District Action. On March 16, 2009 and March 26, 2009, respectively, legal actions were commenced by Ms. Roni Katriel, a former employee of CTI's former subsidiary, Comverse Limited, against Comverse Limited in the Tel Aviv Regional Labor Court (Case Number 3444/09) (the “Katriel Labor Action”) and against CTI in the Tel Aviv District Court (Case Number 1334/09) (the “Katriel District Action”). In the Katriel Labor Action, Ms. Katriel is seeking to certify a class of plaintiffs who were granted CTI stock options and were allegedly damaged as a result of the suspension of option exercises during CTI's previous extended filing delay period. In the Katriel District Action, in addition to a small amount of individual damages, Ms. Katriel is seeking to certify a class of plaintiffs who were allegedly damaged due to their inability to exercise CTI stock options as a result of alleged negligence by CTI in its financial reporting. The class certification motions do not specify an amount of damages. On March 2, 2010, the Katriel Labor Action was transferred to the Tel Aviv District Court, based on an agreed motion filed by the parties requesting such transfer.
	On April 4, 2012, Ms. Deutsch and Ms. Katriel filed an uncontested motion to consolidate and amend their claims and on June 7, 2012, the District Court allowed Ms. Deutsch and Ms. Katriel to file the consolidated class certification motion and an amended consolidated complaint against VSL, CTI, and Comverse Limited. Following CTI's announcement of its intention to effect the Comverse share distribution, on July 12, 2012, the plaintiffs filed a motion requesting that the District Court order CTI to set aside up to $150.0 million in assets to secure any future judgment. The District Court ruled that it would not decide this motion until the Deutsch and Katriel class certification motion was heard. Plaintiffs initially filed a motion to appeal this ruling in August 2012, but subsequently withdrew it in July 2014.
	Prior to the consummation of the Comverse share distribution, CTI either sold or transferred substantially all of its business operations and assets (other than its equity ownership interests in us and Comverse) to Comverse or unaffiliated third parties. On October 31, 2012, CTI completed the Comverse share distribution, in which it distributed all of the outstanding shares of common stock of Comverse to CTI's shareholders. As a result of the Comverse share distribution, Comverse became an independent public company and ceased to be a wholly owned subsidiary of CTI, and CTI ceased to have any material assets other than its equity interest in us.
	On February 4, 2013, we completed the CTI Merger. As a result of the CTI Merger, we have assumed certain rights and liabilities of CTI, including any liability of CTI arising out of the Deutsch District Action and the Katriel District Action. However, under the terms of the Distribution Agreement between CTI and Comverse relating to the Comverse share distribution, we, as successor to CTI, are entitled to indemnification from Comverse for any losses we suffer in our capacity as successor-in-interest to CTI in connection with the Deutsch District Action and the Katriel District Action.
	Following an attempt to mediate the dispute, on July 1, 2014, the plaintiffs filed a notice with the District Court informing it that the mediation process had been unsuccessful. As a result, the parties have filed summations on the plaintiffs’ motion to certify the suit as a class action, which are under consideration by the District Court.
	From time to time we or our subsidiaries may be involved in legal proceedings and/or litigation arising in the ordinary course of our business. While the outcome of these matters cannot be predicted with certainty, we do not believe that the outcome of any current claims will have a material effect on our consolidated financial position, results of operations, or cash flows.

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION
	Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the enterprise’s chief operating decision maker ("CODM"), or decision making group, in deciding how to allocate resources and in assessing performance. Our Chief Executive Officer is our CODM.
	We conduct our business through three operating segments—Enterprise Intelligence Solutions ("Enterprise Intelligence"), Communications and Cyber Intelligence Solutions ("Communications Intelligence"), and Video and Situation Intelligence Solutions ("Video Intelligence"). Organizing our business through three operating segments allows us to align our resources and domain expertise to effectively address the Actionable Intelligence market. We address the Customer Engagement Optimization market opportunity through solutions from our Enterprise Intelligence segment. We address the Security Intelligence market opportunity through solutions from our Communications Intelligence segment and Video Intelligence segment, and we address the Fraud, Risk, and Compliance market opportunity through solutions from all three operating segments.
	We measure the performance of our operating segments based upon operating segment revenue and operating segment contribution. Operating segment contribution includes segment revenue and expenses incurred directly by the segment, including material costs, service costs, research and development and selling, marketing, and administrative expenses. We do not allocate certain expenses, which include the majority of general and administrative expenses, facilities and communication expenses, purchasing expenses, manufacturing support and logistic expenses, depreciation and amortization, amortization of capitalized software development costs, stock-based compensation, and special charges such as restructuring costs when calculating operating segment contribution. These expenses are included in the unallocated expenses section of the table presented below. Revenue from transactions between our operating segments is not material.
	Operating results by segment for the three months ended April 30, 2015 and 2014 were as follows:
		Three Months Ended

	Other expense, net	(7,932		)	(14,265		)
	Income (loss) before provision (benefit) for income taxes	$	1,678		$	(13,269	)
	Revenue adjustments represent revenue of acquired companies which is included within segment revenue reviewed by the CODM, but not recognizable within GAAP revenue.  These adjustments primarily relate to the acquisition-date excess of the historical carrying value over the fair value of acquired companies’ future maintenance and service performance obligations. As the obligations are satisfied, we report our segment revenue using the historical carrying values of these obligations, which we believe better reflects our ongoing maintenance and service revenue streams, whereas GAAP revenue is reported using the obligations’ acquisition-date fair values.
	With the exception of goodwill and acquired intangible assets, we do not identify or allocate our assets by operating segment.  Consequently, it is not practical to present assets by operating segment.  There were no material changes in the allocation of goodwill and acquired intangible assets by operating segment during the three months ended April 30, 2015 and 2014.  The allocations of goodwill and acquired intangible assets by operating segment appear in Note 5, "Intangible Assets and Goodwill".

	Apr. 30, 2015
Accounting Policies [Abstract]
Preparation of Condensed Consolidated Financial Statements	Preparation of Condensed Consolidated Financial Statements
	The condensed consolidated financial statements included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and on the same basis as the audited consolidated financial statements included in our Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (“SEC”) for the year ended January 31, 2015. The condensed consolidated statements of operations, comprehensive income, stockholders’ equity, and cash flows for the periods ended April 30, 2015 and 2014, and the condensed consolidated balance sheet as of April 30, 2015, are not audited but reflect all adjustments that are of a normal recurring nature and that are considered necessary for a fair presentation of the results for the periods shown. The condensed consolidated balance sheet as of January 31, 2015 is derived from the audited consolidated financial statements presented in our Annual Report on Form 10-K for the year ended January 31, 2015. Certain information and disclosures normally included in annual consolidated financial statements have been omitted pursuant to the rules and regulations of the SEC. Because the condensed consolidated interim financial statements do not include all of the information and disclosures required by GAAP for a complete set of financial statements, they should be read in conjunction with the audited consolidated financial statements and notes included in our Annual Report on Form 10-K filed with the SEC for the year ended January 31, 2015. The results for interim periods are not necessarily indicative of a full year’s results.
Principles of Consolidation	Principles of Consolidation
	The accompanying condensed consolidated financial statements include the accounts of Verint Systems Inc., our wholly owned subsidiaries, and a joint venture in which we hold a 50% equity interest.  This joint venture functions as a systems integrator for Asian markets and is a variable interest entity in which we are the primary beneficiary. The noncontrolling interest in this joint venture is reflected within stockholders’ equity on our condensed consolidated balance sheet, but separately from our equity. Investments in companies in which we have less than a 20% ownership interest and do not exercise significant influence are accounted for at cost.  We include the results of operations of acquired companies from the date of acquisition.  All significant intercompany transactions and balances are eliminated.
Use of Estimates	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires our management to make estimates and assumptions, which may affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period.  Actual results could differ from those estimates.
Significant Accounting Policies	Significant Accounting Policies
	Our significant accounting policies are described in Note 1 to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended January 31, 2015. There were no material changes to our significant accounting policies during the three months ended April 30, 2015.
New Accounting Pronouncements, Policy	Recent Accounting Pronouncements
	New Accounting Pronouncements Recently Adopted
	In April 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. ASU No. 2014-08 raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. It was effective for us on February 1, 2015. The adoption of this standard did not impact our condensed consolidated financial statements.
	In January 2015, the FASB issued ASU No. 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. ASU No. 2015-01 eliminates the concept of an extraordinary item from GAAP. As a result, an entity is no longer required to separately present an extraordinary item on its statement of operations, net of tax, after income from continuing operations or to disclose income taxes and net income per share data applicable to an extraordinary item. However, ASU No. 2015-01 still retains the presentation and disclosure guidance for items that are unusual in nature and occur infrequently. ASU No. 2015-01 was effective for us on February 1, 2015. The adoption of this standard did not impact our condensed consolidated financial statements.
	New Accounting Pronouncements Not Yet Effective
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). ASU No. 2014-09 supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific revenue recognition guidance throughout the Industry Topics of the Accounting Standards Codification. Additionally, this update supersedes some cost guidance included in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. As currently issued, this guidance is effective for the first interim period within annual reporting periods beginning after December 15, 2016, and early adoption is not permitted; however, on April 1, 2015, the FASB voted to propose a one-year deferral to the effective date, but to permit entities to adopt one year earlier, at the original effective date. The proposal to defer the effective date will be subject to the FASB’s due process procedures, including a period for public comments. Entities may choose from two adoption methods, with certain practical expedients. We are currently reviewing this standard to assess the impact on our future condensed consolidated financial statements and evaluating the available adoption methods.
	In June 2014, the FASB issued ASU No. 2014-10, Development Stage Entities (Topic 915): Elimination of Certain Financial Reporting Requirements, Including an Amendment to Variable Interest Entities Guidance in Topic 810, Consolidation. ASU No. 2014-10 removes the financial reporting distinction between development stage entities and other reporting entities from GAAP and it eliminates an exception provided in the consolidation guidance for development stage enterprises. It is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, although early adoption is permitted. We are currently reviewing this standard to assess the impact on our future condensed consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-12, Compensation—Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period, which requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. ASU No. 2014-12 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, although early adoption is permitted. We are currently reviewing this standard to assess the impact on our future condensed consolidated financial statements.
	In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern. This ASU defines management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. The provisions of ASU No. 2014-15 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, although early adoption is permitted. The adoption of ASU No. 2014-15 is not expected to have a material effect on our future condensed consolidated financial statements.
	In April 2015, the FASB issued ASU No. 2015-03, Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. ASU No. 2015-03 requires an entity to present debt issuance costs related to a recognized debt liability in the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this update. The provisions of ASU No. 2015-03 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, although early adoption is permitted. When adopted, this guidance must be applied on a retrospective basis. We plan to adopt the provisions of ASU No. 2015-03 effective on February 1, 2016. As of April 30, 2015, we have $14.2 million of net deferred debt issuance costs which are reported within Other assets on our condensed consolidated balance sheet.
	In April 2015, the FASB issued ASU No. 2015-05, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Fees Paid in a Cloud Computing Arrangement. The amendments in this update provide guidance to customers about whether a cloud computing arrangement includes a software license. The provisions of ASU No. 2015-05 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, although early adoption is permitted. We are currently reviewing this standard to assess the impact on our future condensed consolidated financial statements.
