	The accompanying unaudited consolidated financial statements include the accounts of Intralinks Holdings, Inc. and its subsidiaries (collectively, the "Company"). The consolidated financial statements included in this report have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States ("GAAP" or "U.S. GAAP") have been condensed or omitted pursuant to such SEC rules and regulations. The Company believes that the disclosures are adequate to make the information presented not misleading.
	The financial statements contained herein should be read in conjunction with the Company’s audited consolidated financial statements and related notes to audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012.
	In the opinion of management, the accompanying unaudited consolidated financial statements contain all normal and recurring adjustments necessary for the fair statement of the consolidated financial condition, results of operations and changes in cash flows of the Company for the interim periods presented. The Company’s historical results are not necessarily indicative of future operating results, and the results for the nine months ended September 30, 2013 are not necessarily indicative of results to be expected for the full year or for any other period.
	Out-of-period Adjustments — During the financial statement close process for the three months ended June 30, 2013, the Company identified a prior period error totaling approximately $839, which was corrected and recorded as a cumulative adjustment to long-term deferred tax assets within the Consolidated Balance Sheet at June 30, 2013, and was reflected as an income tax expense within the Consolidated Statement of Operations for the three and six months ended June 30, 2013. The Company does not believe that this adjustment is material to the consolidated financial statements for any prior period. The Company also does not believe this adjustment will be material to the Company's 2013 results.
	During the financial statement close process for the three months ended March 31, 2012, the Company identified a prior period error totaling approximately $849, which was corrected and recorded as a cumulative adjustment to long-term deferred tax assets within the Consolidated Balance Sheet at March 31, 2012, and was reflected as an income tax benefit within the Consolidated Statement of Operations for the three months ended March 31, 2012. The Company does not believe that this adjustment is material to the consolidated financial statements for any prior period or to the 2012 results.

	Summary of Significant Accounting Policies
	Revenue Recognition — The Company derives revenue principally through fixed commitment contracts under which the Company provides customers various services, including access to the cloud-based Intralinks platform, which includes Intralinks exchanges, as well as related customer support and other services. The Company's customers do not have a contractual right, or the ability, to take possession of the Intralinks software at any time during the hosting period, or to contract with an unrelated third party to host the Intralinks software. Therefore, revenue recognition for the Company's services is not accounted for under specific guidance of the Financial Accounting Standards Board ("FASB") on software revenue recognition. The Company recognizes revenue for its services ratably over the related service period, provided that there is persuasive evidence of an arrangement; the service has been provided to the customer; collection is reasonably assured; the amount of fees to be paid by the customer is fixed or determinable; and the Company has no significant remaining obligation at the completion of the contracted term. In circumstances where the Company has a significant remaining obligation after completion of the initial contract term, revenue is recognized ratably over the extended service period. The Company's contracts do not contain general rights of return. Certain of the Company's contracts contain customer acceptance clauses, for which revenue is deferred until acceptance occurs.
	From time to time, the Company agrees to sales concessions with its customers for which a reserve is estimated based on historical patterns of actual credits issued. Expenses associated with maintaining this reserve are recorded as a reduction to revenue, which the Company believes represents an accurate reflection of the underlying business activity for each reporting period and is in line with the requirement that all revenue recognized during the period is earned and realizable.
	The Company offers services to customers through single-element and multiple-element arrangements, some of which contain offerings for optional services, including document scanning, data archiving and other professional services. In accordance with the FASB's guidance on multiple-deliverable arrangements, the Company has evaluated the deliverables in its arrangements to determine whether they represent separate units of accounting and, specifically, whether the deliverables have value to the Company's customers on a standalone basis. The Company has determined that the services delivered to customers under its existing arrangements generally represent a single unit of accounting. Revenue for optional services is recognized as delivered, or as completed, provided that the general revenue recognition criteria described above are met. The Company continues to evaluate the nature of the services offered to customers under its fixed commitment contracts, as well as its pricing practices, to determine if a change in policy regarding multiple-element arrangements and related disclosures is warranted in future periods.
	Additionally, certain contracts contain provisions for set-up and implementation services relating to the customer's use of the Intralinks platform. The Company believes that these set-up and implementation services provide value to the customer over the entire period that the exchange is active, including renewal periods, and therefore the revenue related to these set-up types of services are recognized over the longer of the contract term or the estimated relationship life. The Company will continue to evaluate from time to time the length of the amortization period of the revenue related to set up and implementation fees to determine if a change in estimate is warranted in future periods.
	During the nine months ended September 30, 2013, there were no material changes to the Company's significant accounting policies from those disclosed in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2012.
	Recent Accounting Pronouncements
	In June 2013, the FASB ratified accounting guidance proposed by the Emerging Issues Task Force that requires entities to present an unrecognized tax benefit net with certain deferred tax assets when specific requirements are met. The amendments in this updated guidance are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The Company is currently evaluating the effect this guidance will have on its consolidated balance sheet.

	The Company has classified its short-term investments in commercial paper and corporate bonds as held-to-maturity and, as such, has recorded them at amortized cost. Interest earned on these debt securities is included in "Other (income) expense, net" within the Consolidated Statements of Operations. The gross unrecognized holding gains and losses on these assets for the three and nine months ended September 30, 2013 were not material.
	The following tables summarize these short-term investments as of September 30, 2013 and December 31, 2012:
						30-Sep-13

	Corporate Notes		152 to 365 Days		Investments (short-term)	29,056
	Total					$	34,058
	The fair value framework under the FASB’s guidance requires the categorization of assets and liabilities into three levels based upon the assumptions used to measure the assets or liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3, if applicable, generally would require significant management judgment. The three levels for categorizing assets and liabilities under the fair value measurement requirements 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.
	During the nine months ended September 30, 2013, there were no transfers in or out of the Company’s Level 1, Level 2 or Level 3 assets or liabilities.
	The following tables summarize those of the Company's assets that were measured at fair value on a recurring basis as of September 30, 2013 and December 31, 2012:

	At September 30, 2013, the Company had recorded $215,869 of goodwill. Goodwill is assessed for impairment annually (as of October 1) or more frequently if events or changes in circumstances indicate that this asset may be impaired. The Company’s operations consist of one reporting unit, which is evaluated during each goodwill impairment assessment.
	The Company's most recently completed qualitative impairment assessment is as of October 1, 2012. Among the factors included in this qualitative assessment were general economic conditions and the competitive environment, actual and expected financial performance, including consideration of the Company's revenue growth and operating results year-over-year, forward-looking business measurements, external market conditions, the Company's stock price performance compared to overall market and industry peers, market capitalization and other relevant entity-specific events.
	The Company is in the process of preparing its annual goodwill impairment assessment as of October 1, 2013 and will disclose the results of this assessment in its Annual Report on Form 10-K for the fiscal year ending December 31, 2013. There have been no triggering events since the most recently completed assessment as of October 1, 2012 to indicate that the Company could be at risk of recording a goodwill impairment.

	Income Tax
	The Company's effective tax rates for the three and nine month periods ended September 30, 2013 were 23.7% and 24.7%, respectively. These effective tax rates differ from the U.S. Federal statutory tax rate due primarily to non tax-deductible stock-based compensation expense for incentive stock options ("ISOs") and the Company's 2010 Employee Stock Purchase Plan ("2010 ESPP"), foreign income taxes and state and local income taxes, offset by federal and state research and development tax credits and tax benefits from ISO disqualifications. In addition, the nine month effective tax rate at September 30, 2013 was increased by the out-of-period adjustment discussed in Note 1 above.
	The Company's effective tax rates for the three and nine month periods ended September 30, 2012 were 48.7% and 36.3%, respectively. These effective tax rates differ from the U.S. Federal statutory tax rate due primarily to non tax-deductible stock-based compensation expense for ISOs and the 2010 ESPP, foreign income taxes and state and local income taxes, offset by state research and development tax credits and tax benefits from ISO disqualifications.
	In the second quarter of 2013, the Company concluded an audit by the U.S. Internal Revenue Service (“IRS”) of its U.S. Federal income tax returns for the years ended December 31, 2006 through 2009. The Company received Notices of Proposed Adjustments for 2006, 2007 and 2008 from the IRS disallowing $58.3 million of foreign branch losses on the basis that they constitute dual consolidated losses in the U.S. and the IRS is asserting that the Company is not entitled to reasonable cause relief for late election filings. The Company disagrees with the proposed adjustments and has filed an appeal. Management believes that it is more likely than not that the Company's position with respect to these adjustments will be sustained.
	Unrecognized tax benefits totaled $3,847 and $3,335 at September 30, 2013 and December 31, 2012, respectively. Management does not expect that the balance of unrecognized tax benefits will significantly increase or decrease over the next twelve months.
	The Company's tax reserves for uncertain tax positions of $4,005 (including interest and penalties of $158) are included within “Other long term liabilities” on the September 30, 2013 Consolidated Balance Sheet.

	Debt consisted of the following:
		September 30,			December 31,

	Less: current portion (Other financing arrangements)	(225		)	(209		)
	Total long-term debt	$	153		$	75,238
	In the second quarter of 2013, the Company classified the balance of $75,103 of long-term debt related to the First Lien Credit Facility to current liabilities because the First Lien Credit Facility expires June 15, 2014. Based on available market information, the estimated fair value of the Company’s total debt was approximately $75,385 and $76,647 as of September 30, 2013 and December 31, 2012, respectively. These fair value measurements were determined using Level 2 observable inputs. The estimated fair value of the Company’s other financing arrangements approximates the carrying value at each reporting period.
	First Lien Credit Facility
	The First Lien Credit Facility provides for term loans in the aggregate principal amount of $135,000. Principal payments are due on the last day of each quarter, with the first payment made on September 30, 2007 and the final installment (which will include the remaining balance) due on June 15, 2014. Additionally, the First Lien Credit Facility includes a requirement for mandatory prepayments based on annual excess free cash flow. Term loans under the First Lien Credit Facility, as amended, bear interest at the higher of the Eurodollar Rate (as defined in the agreement) or 1.50%, plus 4.50% per annum. At September 30, 2013, the interest rate on the First Lien Credit Facility was 6.00%. At September 30, 2012, the interest rate on the First Lien Credit Facility was 5.75%.
	The First Lien Credit Facility limits annual consolidated capital expenditures, including amounts related to capitalized software, and restricts the ability to borrow against the now expired revolving line of credit if a consolidated EBITDA ratio is not achieved. The agreement also contains other positive and negative covenants. The Company was in compliance with these covenants as of September 30, 2013 and December 31, 2012.
	On April 6, 2012, the Company entered into Amendment No. 3 (the "Third Amendment") to the First Lien Credit Facility. The Third Amendment amends certain provisions of the First Lien Credit Facility to, among other things, increase the capital expenditures limit from $21,000 to $35,000 per year through the remainder of the term. As provided for in the Third Amendment, the Company prepaid $15,000 of the outstanding balance on the First Lien Credit Facility. As a result, the quarterly installment payment beginning June 30, 2012 decreased from $246 to $205 for the remaining term of the loan.
	The First Lien Credit Facility also provided for a $15,000 revolving line of credit, which expired on June 15, 2013. The obligations previously covered by the Company's revolving line of credit, which were primarily related to the Company's operating lease agreements for its various office locations, were replaced under a separate cash collateralized facility under which the Company originally provided the bank with $2,464 and they provided certain of the Company's landlords with separate letters of credit for each location. The cash collateral balance is $2,442 at September 30, 2013. This facility expires on June 3, 2014 and as such is classified as current restricted cash on the Company's Consolidated Balance Sheet. In May 2013, a requirement for a $800 standby letter of credit related to the Company's corporate charge card utilized by executives and certain other employees was terminated.

	As originally adopted in 2010, a maximum of 400,000 shares of the Company's Common Stock had been reserved for issuance under the Company's 2010 Employee Stock Purchase Plan (the "ESPP"). On August 9, 2013, the Company's stockholders approved a proposal that resulted in an additional 600,000 shares being made available for issuance under the ESPP, resulting in an aggregate of 1,000,000 shares being available for issuance under the ESPP. As of August 9, 2013, there were 633,261 shares available for grant under the ESPP.
	During the three months ended September 30, 2013, 29,807 shares were issued under the ESPP at a price of $6.23 which represented 85% of the market price of the Common Stock on July 1, 2013, the offering date, which was lower than the market price of the Common Stock on September 30, 2013, which was the exercise date.

	Legal Proceedings
	In the ordinary course of business, the Company and its subsidiaries are subject to various claims, charges, disputes, litigation and regulatory inquiries and investigations. These matters, if resolved adversely against the Company, may result in monetary damages, fines and penalties or require changes in business practices. The Company is not currently aware of any pending or threatened material claims, charges, disputes, litigation and regulatory inquiries and investigations except as follows:
	Securities Class Action. On December 5, 2011, the Company became aware of a purported class action lawsuit filed in the U.S. District Court for the Southern District of New York (the "SDNY" or the "Court") against the Company and certain of its then current and former executive officers. The initial complaint (the "Wallace Complaint") alleges that the defendants made false and misleading statements or omissions in violation of the Securities Exchange Act of 1934, as amended. The plaintiff seeks unspecified compensatory damages for the purported class of purchasers of the Company's Common Stock during the period from February 17, 2011 through November 10, 2011 (the "Allegation Period"). On December 27, 2011, a second purported class action complaint, which makes substantially the same claims as, and is related to, the Wallace Complaint, was filed in the SDNY against the Company and certain of its current and former executive officers seeking similar unspecified compensatory damages for the Allegation Period.  On April 3, 2012, the Court consolidated the actions and appointed Plumbers and Pipefitters National Pension Fund as lead plaintiff, and also appointed lead counsel in the consolidated action ("Consolidated Class Action").  On June 15, 2012, the lead plaintiff filed an amended complaint (“Consolidated Class Action Complaint”), that in addition to the original allegations made in the Wallace Complaint, alleges that the Company, certain of its current and former officers and directors, and the underwriters in the Company's April 6, 2011 stock offering issued a registration statement and prospectus in connection with the offering that contained untrue statements of material fact or omitted material information required to be stated therein in violation of the Securities Act of 1933, as amended.  The defendants filed their motion to dismiss the action on July 31, 2012, and in response to the lead plaintiff’s opposition to the defendants' motions, which was filed on September 17, 2012, the defendants filed their replies to plaintiff's opposition on October 10, 2012.  On May 8, 2013, the Court issued an opinion dismissing claims based on certain allegations in the complaint, but otherwise denied defendants' motions to dismiss.  On June 28, 2013, defendants filed their answers to the Consolidated Class Action Complaint. On October 15, 2013, the Court entered the parties’ pretrial scheduling stipulation, which provided, inter alia, that the parties would fully brief any motions for summary judgment by February 17, 2015. The Company believes that these claims are without merit and intends to defend these lawsuits vigorously.
	Dixon Derivative Action.  On December 28, 2011, a shareholder derivative complaint was filed in the SDNY against the Company and certain of its current and former directors. The complaint (the "Dixon Action") alleges that the defendants breached their fiduciary duties by causing the Company to issue materially false and misleading statements about the Company's business prospects, financial condition and performance during the same Allegation Period alleged in the Consolidated Class Action Complaint. On June 6, 2013, the parties filed a stipulation with the SDNY agreeing to stay all proceedings in the Dixon Action, including discovery, until ninety days after the SDNY issues a scheduling order in the Consolidated Class Action. The Company believes that the claims in the Dixon Action are without merit and intends to defend this lawsuit vigorously.
	Horbal Derivative Action. On April 16, 2012, a second shareholder derivative complaint (the "Horbal Action") was filed in the Supreme Court of the State of New York in New York County ("New York State Court") against the Company and certain of its current and former directors and officers. The Horbal Action makes substantially the same claims as, and is related to, the Dixon Action, except that it alleges violations of state law. On April 24, 2012, one of the director defendants removed the Horbal Action to the SDNY, and on May 7, 2012, it was assigned to the same judge as in the Dixon Action. On May 22, 2012, the plaintiff in the Horbal Action moved to remand the case to New York State Court. On June 8, 2012, defendant filed an opposition to remand, and the plaintiff filed a reply on June 15, 2012. On March 11, 2013, the SDNY granted plaintiff's motion to remand, and the case is currently pending in New York State Court. On June 6, 2013, the parties filed a stipulation with the New York State Court agreeing to stay all proceedings in the Horbal Action, including discovery, until ninety days after the SDNY issues a scheduling order in the Consolidated Class Action. The Company believes the claims in the Horbal Action are without merit and intends to defend this lawsuit vigorously.
	Levine Shareholder Demand Letter. The Company received a shareholder demand letter, dated May 16, 2013, demanding that the Company's Board take action to remedy alleged breaches of fiduciary duty by current and former directors and officers of the Company. These alleged breaches are based on the same alleged misconduct in the complaints in the Dixon, Horbal, and Consolidated Class Actions. The letter specifically demands that the Company's Board undertake an independent internal investigation into the alleged breaches and commence a civil action against each of the allegedly breaching current and former directors and officers. On June 26, 2013, the Company's Board created a Demand Committee to conduct an investigation into the allegations in the Levine demand letter.
	SEC Investigation.  On July 10, 2013, the Company announced that it received written notification from the SEC that the SEC's investigation into the Company, as previously disclosed, has been terminated and that no enforcement action has been recommended against the Company. The investigation commenced on August 4, 2011 upon the SEC's request for certain documents related to the Company's business from January 1, 2011 through August 4, 2011.

	Sep. 30, 2013
Accounting Policies [Abstract]	'
Principles of Consolidation	'
	The accompanying unaudited consolidated financial statements include the accounts of Intralinks Holdings, Inc. and its subsidiaries (collectively, the "Company"). The consolidated financial statements included in this report have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC").
Revenue Recognition	'
	Revenue Recognition — The Company derives revenue principally through fixed commitment contracts under which the Company provides customers various services, including access to the cloud-based Intralinks platform, which includes Intralinks exchanges, as well as related customer support and other services. The Company's customers do not have a contractual right, or the ability, to take possession of the Intralinks software at any time during the hosting period, or to contract with an unrelated third party to host the Intralinks software. Therefore, revenue recognition for the Company's services is not accounted for under specific guidance of the Financial Accounting Standards Board ("FASB") on software revenue recognition. The Company recognizes revenue for its services ratably over the related service period, provided that there is persuasive evidence of an arrangement; the service has been provided to the customer; collection is reasonably assured; the amount of fees to be paid by the customer is fixed or determinable; and the Company has no significant remaining obligation at the completion of the contracted term. In circumstances where the Company has a significant remaining obligation after completion of the initial contract term, revenue is recognized ratably over the extended service period. The Company's contracts do not contain general rights of return. Certain of the Company's contracts contain customer acceptance clauses, for which revenue is deferred until acceptance occurs.
	From time to time, the Company agrees to sales concessions with its customers for which a reserve is estimated based on historical patterns of actual credits issued. Expenses associated with maintaining this reserve are recorded as a reduction to revenue, which the Company believes represents an accurate reflection of the underlying business activity for each reporting period and is in line with the requirement that all revenue recognized during the period is earned and realizable.
	The Company offers services to customers through single-element and multiple-element arrangements, some of which contain offerings for optional services, including document scanning, data archiving and other professional services. In accordance with the FASB's guidance on multiple-deliverable arrangements, the Company has evaluated the deliverables in its arrangements to determine whether they represent separate units of accounting and, specifically, whether the deliverables have value to the Company's customers on a standalone basis. The Company has determined that the services delivered to customers under its existing arrangements generally represent a single unit of accounting. Revenue for optional services is recognized as delivered, or as completed, provided that the general revenue recognition criteria described above are met. The Company continues to evaluate the nature of the services offered to customers under its fixed commitment contracts, as well as its pricing practices, to determine if a change in policy regarding multiple-element arrangements and related disclosures is warranted in future periods.
	Additionally, certain contracts contain provisions for set-up and implementation services relating to the customer's use of the Intralinks platform. The Company believes that these set-up and implementation services provide value to the customer over the entire period that the exchange is active, including renewal periods, and therefore the revenue related to these set-up types of services are recognized over the longer of the contract term or the estimated relationship life. The Company will continue to evaluate from time to time the length of the amortization period of the revenue related to set up and implementation fees to determine if a change in estimate is warranted in future periods.
