Organization, Consolidation and Presentation of Financial Statements [Abstract]
Intralinks Holdings, Inc. and Summary of Significant Accounting Policies	Intralinks Holdings, Inc. and Summary of Significant Accounting Policies Intralinks Holdings, Inc. ("Intralinks Holdings") and its subsidiaries (collectively, the "Company") is a leading global provider of Software-as-a-Service ("SaaS") solutions for secure enterprise content collaboration within and among organizations. The Company was incorporated in Delaware in June 1996. The Company's cloud-based solutions enable organizations to manage, control, track, search, exchange and collaborate on sensitive information, inside and outside of the firewall, all within a secure and easy-to-use environment. Basis of Presentation The accompanying unaudited Consolidated Financial Statements include the accounts of Intralinks Holdings and its subsidiaries. All intercompany balances and transactions have been eliminated. The accompanying unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") for interim financial information and with the rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such SEC rules and regulations. In the opinion of management, the accompanying unaudited Consolidated Financial Statements contain all normal and recurring adjustments necessary for the fair statement of the Company's consolidated financial position, results of operations and cash flows for the interim periods presented. Interim results are not necessarily indicative of the results to be expected for a full year. The financial statements contained herein are unaudited and should be read in conjunction with the Company’s audited Consolidated Financial Statements and related notes included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2015 . Certain prior year amounts have been reclassified to conform to the current year presentation. Use of Estimates The preparation of the Company's Consolidated Financial Statements in conformity with U.S. GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from those estimates. On an ongoing basis, the Company evaluates its estimates and assumptions including those related to (a) allowances for doubtful accounts and reserves for customer credits, (b) the fair values of the Company's single operating segment and reporting unit, goodwill, definite-lived intangible assets and long-term investments, (c) the recoverability of its definite-lived intangible assets, capitalized software and fixed assets (and their related useful lives), (d) certain components of the income tax provision (including the valuation allowance on net deferred tax assets and liabilities for uncertain tax positions), (e) accruals for certain compensation and benefit expenses and (f) the fair value of stock-based awards including estimated forfeitures of such awards. The Company bases its estimates, judgments and assumptions on historical experience, its forecasts and budgets and on various other factors that it believes to be reasonable under the circumstances. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers , which outlines a single comprehensive model for entities to use in accounting for revenue. ASU 2014-09 supersedes current revenue recognition guidance and requires an entity to recognize revenue when it transfers 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. Entities have the option of using either a full retrospective or a modified retrospective approach to adopt ASU 2014-09. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date . The amendment in this update deferred the effective date of implementation of ASU 2014-09 by one year and is now effective for annual and interim reporting periods beginning after December 15, 2017. In March 2016, the FASB issued ASU 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net) , amending the principal-versus-agent implementation guidance set forth in ASU 2014-09. The amendment clarifies that an entity should evaluate whether it is the principal or the agent for each specified good or service promised in a contract with a customer. In April 2016, the FASB issued ASU 2016-10, Identifying Performance Obligations and Licensing , which amends certain aspects of the guidance set forth in the FASB's new revenue standard related to identifying performance obligations and licensing implementation. In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients , which clarifies implementation guidance in ASU 2014-09 on assessing collectability, noncash consideration, presentation of sales tax and completed contracts and contract modifications at transition. The Company is currently evaluating the impact of the adoption of these standards on its Consolidated Financial Statements. In April 2015, the FASB issued ASU 2015-03, Interest-Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs , which requires an entity to present debt issuance costs on the balance sheet as a direct deduction from the related liability rather than as an asset. ASU 2015-03 is effective for annual and interim reporting periods beginning after December 15, 2015. In August 2015, the FASB issued ASU 2015-15, Interest-Imputation of Interest: Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements , which clarifies that the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are outstanding borrowings on the line-of-credit. As a result of the retrospective adoption of ASU 2015-03, at December 31, 2015 , the Company reclassified capitalized deferred debt issuance costs of $0.5 million from "Other current assets" to "Current portion of long-term debt, net of debt issuance costs" and $1.0 million from "Other non-current assets" to "Long-term debt, net of debt issuance costs." In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , which supersedes existing guidance on accounting for leases in "Leases (Topic 840)" and generally requires all leases to be recognized in the consolidated balance sheet. ASU 2016-02 is effective for annual and interim reporting periods beginning after December 15, 2018; early adoption is permitted. The provisions of ASU 2016-02 are to be applied using a modified retrospective approach. The Company is currently evaluating the impact of the adoption of this standard on its Consolidated Financial Statements. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting , which simplifies the accounting for employee stock-based payment. This update provides clarification on guidance for employee share-based payments, in particular areas including income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Company is currently evaluating the impact of the adoption of these standards on its Consolidated Financial Statements.

Fair Value Disclosures [Abstract]
Investments and Fair Value Measurements	Investments and Fair Value Measurements The Company has classified its investments in corporate securities as held-to-maturity and, as such, has recorded them at amortized cost. Interest earned on these corporate securities is included in “Other expense (income), net” within the Consolidated Statements of Operations. The gross unrealized holding gains and losses for the three and nine months ended September 30, 2016 and 2015 were not material. The Company held no investments at September 30, 2016 . The following table summarizes these investments at December 31, 2015 : December 31, 2015 Security Type Remaining Maturity Consolidated Balance Sheet Classification Amortized Cost (In thousands) Corporate Securities 15 to 202 Days Investments (current) $ 12,425 The Company categorizes its financial instruments measured at fair value into a three-level fair value hierarchy that prioritizes the inputs used in determining the fair value of the asset or liability. The three levels of the fair value hierarchy are as follows: • Level 1: Fair value measurement of the asset or liability using observable inputs such as quoted prices in active markets for identical assets or liabilities; • Level 2: Fair value measurement of the asset or liability using inputs other than quoted prices that are observable for the applicable asset or liability, either directly or indirectly, such as quoted prices for similar (as opposed to identical) assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active; and • Level 3: Fair value measurement of the asset or liability using unobservable inputs that reflect the Company’s own assumptions regarding the applicable asset or liability. The following tables present the Company's financial instruments that are measured at fair value on a recurring basis: September 30, 2016 Total Level 1 Level 2 Level 3 (In thousands) Asset: Money market funds as cash equivalents $ 16,331 $ 16,331 $ — $ — December 31, 2015 Total Level 1 Level 2 Level 3 (In thousands) Asset: Money market funds as cash equivalents $ 17,143 $ 17,143 $ — $ — The Company's non-financial assets, which include goodwill, intangible assets, fixed assets, capitalized software and cost method investments, are adjusted to fair value only when an impairment charge is recognized. These fair value measurements are based predominantly on Level 3 inputs. At September 30, 2016 and December 31, 2015 , the carrying value of the Company's investments accounted for under the cost method totaled $3.0 million and $4.5 million , respectively, and are included in "Other non-current assets" on the Company's Consolidated Balance Sheets. During the nine months ended September 30, 2016 , the Company recognized an impairment charge of $1.5 million related to the write-down of a cost method investment to its estimated fair value of zero . The decline in value was determined to be other-than-temporary due to the investee company’s inability to continue operations without new outside financing. The impairment charge is included in “Other (income) expense, net” in the Consolidated Statements of Operations.

Income Tax Disclosure [Abstract]
Income Tax	Income Tax The Company recorded an income tax expense of $0.7 million and $1.5 million despite a pre-tax loss of $0.5 million and $12.6 million for the three and nine months ended September 30, 2016 , respectively, and recorded an income tax expense of $0.4 million and $1.2 million despite a pre-tax loss of $6.1 million and $23.2 million for the three and nine months ended September 30, 2015 , respectively, primarily because the income tax benefit related to the U.S. pre-tax loss generated was subject to a valuation allowance. In addition, certain foreign jurisdictions generated pre-tax income that resulted in tax expense. The Company is routinely under audit by federal, state, local and foreign tax authorities in the area of income tax. These audits include questioning the timing and the amount of income and deductions and the allocation of income and deductions among various tax jurisdictions. The Internal Revenue Service recently completed an audit of the Company’s federal tax returns for the years ended December 31, 2010 and 2011. Various other jurisdictions are open to examination for various tax years. Management believes it has adequately provided for all uncertain tax positions and any potential audit adjustments would not have a material impact on the Company’s liquidity, results of operations or financial condition. Unrecognized tax benefits totaled $6.8 million and $5.5 million at September 30, 2016 and December 31, 2015 , respectively. Management does not expect that the balance of unrecognized tax benefits will significantly increase or decrease over the next twelve months. If unrecognized tax benefits at September 30, 2016 are subsequently recognized, the Company's income tax expense would be reduced by $5.7 million ( $0.7 million net of the impact of the Company’s valuation allowance).

These fair value measurements were determined using Level 2 observable inputs, as defined in Note 2. The estimated fair value of our facility related to the purchase of equipment ("Equipment Loan Facility") approximates its carrying value at each reporting period. As of September 30, 2016 , the Company had $2.9 million in outstanding letters of credit issued under its Revolving Credit Facility. The Term Loan Credit Facility and the Revolving Credit Facility (collectively, the "Credit Facilities") include covenants that restrict certain activities by the Company, as well as require the Company to comply with certain financial ratios such as a Consolidated Net Leverage Ratio and a springing Fixed Charge Coverage Ratio, as these terms are defined in the agreements governing the Credit Facilities. The agreements governing the Credit Facilities also contain other affirmative and negative covenants with which the Company is required to comply. The Term Loan Credit Facility requires partial prepayment of a portion of the principal outstanding in the event that the Company generates Consolidated Excess Cash Flow (as defined under the Term Loan Credit Facility) in excess of a certain threshold. This determination is to be made 90 days following the end of the preceding fiscal year, with any payment, if required, due within 105 days following the end of the preceding fiscal year. The Company was in compliance with all applicable covenants set forth in the Credit Facilities as of September 30, 2016 and there was no required prepayment for the year ended December 31, 2015 .

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies In the ordinary course of business, the Company and its subsidiaries are subject to various claims, charges, disputes, litigation and regulatory inquiries and investigations. The Company establishes reserves for specific legal matters when it determines that the likelihood of an unfavorable outcome is probable and the loss is reasonably estimable. Management has also identified certain other legal matters where it believes an unfavorable outcome is not probable and, therefore, no reserve is established. Although management currently believes that resolving claims against the Company, including claims where an unfavorable outcome is reasonably possible, will not have a material impact on the Company's liquidity, results of operations or financial condition, these matters are subject to inherent uncertainties and management's view of these matters may change in the future. The Company also evaluates other contingent matters, including income and non-income tax contingencies, to assess the likelihood of an unfavorable outcome and estimated extent of potential loss. These matters, if resolved adversely against the Company, may result in monetary damages, fines and penalties or require changes in business practices. It is possible that an unfavorable outcome of one or more of these lawsuits or other contingencies could have a material impact on the Company's liquidity, results of operations or financial condition. The Company is not currently aware of any pending or threatened material claims, charges, disputes, litigation and regulatory inquiries and investigations.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited Consolidated Financial Statements include the accounts of Intralinks Holdings and its subsidiaries. All intercompany balances and transactions have been eliminated. The accompanying unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") for interim financial information and with the rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such SEC rules and regulations. In the opinion of management, the accompanying unaudited Consolidated Financial Statements contain all normal and recurring adjustments necessary for the fair statement of the Company's consolidated financial position, results of operations and cash flows for the interim periods presented. Interim results are not necessarily indicative of the results to be expected for a full year. The financial statements contained herein are unaudited and should be read in conjunction with the Company’s audited Consolidated Financial Statements and related notes included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2015 . Certain prior year amounts have been reclassified to conform to the current year presentation.
Use of Estimates	Use of Estimates The preparation of the Company's Consolidated Financial Statements in conformity with U.S. GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from those estimates. On an ongoing basis, the Company evaluates its estimates and assumptions including those related to (a) allowances for doubtful accounts and reserves for customer credits, (b) the fair values of the Company's single operating segment and reporting unit, goodwill, definite-lived intangible assets and long-term investments, (c) the recoverability of its definite-lived intangible assets, capitalized software and fixed assets (and their related useful lives), (d) certain components of the income tax provision (including the valuation allowance on net deferred tax assets and liabilities for uncertain tax positions), (e) accruals for certain compensation and benefit expenses and (f) the fair value of stock-based awards including estimated forfeitures of such awards. The Company bases its estimates, judgments and assumptions on historical experience, its forecasts and budgets and on various other factors that it believes to be reasonable under the circumstances.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers , which outlines a single comprehensive model for entities to use in accounting for revenue. ASU 2014-09 supersedes current revenue recognition guidance and requires an entity to recognize revenue when it transfers 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. Entities have the option of using either a full retrospective or a modified retrospective approach to adopt ASU 2014-09. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date . The amendment in this update deferred the effective date of implementation of ASU 2014-09 by one year and is now effective for annual and interim reporting periods beginning after December 15, 2017. In March 2016, the FASB issued ASU 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net) , amending the principal-versus-agent implementation guidance set forth in ASU 2014-09. The amendment clarifies that an entity should evaluate whether it is the principal or the agent for each specified good or service promised in a contract with a customer. In April 2016, the FASB issued ASU 2016-10, Identifying Performance Obligations and Licensing , which amends certain aspects of the guidance set forth in the FASB's new revenue standard related to identifying performance obligations and licensing implementation. In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients , which clarifies implementation guidance in ASU 2014-09 on assessing collectability, noncash consideration, presentation of sales tax and completed contracts and contract modifications at transition. The Company is currently evaluating the impact of the adoption of these standards on its Consolidated Financial Statements. In April 2015, the FASB issued ASU 2015-03, Interest-Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs , which requires an entity to present debt issuance costs on the balance sheet as a direct deduction from the related liability rather than as an asset. ASU 2015-03 is effective for annual and interim reporting periods beginning after December 15, 2015. In August 2015, the FASB issued ASU 2015-15, Interest-Imputation of Interest: Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements , which clarifies that the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are outstanding borrowings on the line-of-credit. As a result of the retrospective adoption of ASU 2015-03, at December 31, 2015 , the Company reclassified capitalized deferred debt issuance costs of $0.5 million from "Other current assets" to "Current portion of long-term debt, net of debt issuance costs" and $1.0 million from "Other non-current assets" to "Long-term debt, net of debt issuance costs." In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , which supersedes existing guidance on accounting for leases in "Leases (Topic 840)" and generally requires all leases to be recognized in the consolidated balance sheet. ASU 2016-02 is effective for annual and interim reporting periods beginning after December 15, 2018; early adoption is permitted. The provisions of ASU 2016-02 are to be applied using a modified retrospective approach. The Company is currently evaluating the impact of the adoption of this standard on its Consolidated Financial Statements. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting , which simplifies the accounting for employee stock-based payment. This update provides clarification on guidance for employee share-based payments, in particular areas including income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Company is currently evaluating the impact of the adoption of these standards on its Consolidated Financial Statements.
