Description of Business and Basis of Presentation	'
	1. Description of Business and Basis of Presentation
	We provide proactive identity theft protection services to our consumer subscribers, whom we refer to as our members, on an annual or monthly subscription basis. We also provide fraud and risk solutions to our enterprise customers.
	We were incorporated in Delaware on April 12, 2005 and are headquartered in Tempe, Arizona. On March 14, 2012, we acquired ID Analytics, Inc. and its wholly-owned subsidiary IDA, Inc., collectively, ID Analytics, each of which is incorporated in Delaware.  On December 11, 2013, we acquired Lemon, Inc., or Lemon, which is incorporated in Delaware.
	Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States, or U.S. GAAP, and applicable rules and regulations of the Securities and Exchange Commission, or SEC, regarding interim financial reporting. Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013.
	The condensed consolidated balance sheet as of December 31, 2013 included herein was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by U.S. GAAP.
	The accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, but are not necessarily indicative of the result of operations to be anticipated for the entire year ending December 31, 2014 or any future period.
	Basis of Consolidation
	The condensed consolidated financial statements include our accounts and those of our wholly-owned subsidiaries. We eliminate all intercompany balances and transactions, including intercompany profits, and unrealized gains and losses in consolidation.
	Use of Estimates
	The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires us to make certain estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. We base our estimates on historical experience, current business factors, and various other assumptions that we believe are necessary to consider in forming a basis for making judgments about the carrying values of assets and liabilities, the recorded amounts of revenue and expenses, and the disclosure of contingent assets and liabilities.

	Significant Accounting Policies
	There have been no material changes to our significant accounting policies as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013.
	Recently Issued Accounting Standards
	In April 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update (ASU) No. 2014-08, Reporting Discontinued Operations and Disclosures of Components of an Entity, which changes the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements.  The updated guidance defines discontinued operations as a disposal of a component or group of components that is disposed of or is classified as held for sale and represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results and expands the disclosure requirements for discontinued operations and adds new disclosures for individually significant dispositions that do not qualify as discontinued operations.  ASU No. 2014-08 is effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2014.  ASU No. 2014-08 would be applied to any future applicable transaction.

	Acquisition of Lemon
	On December 11, 2013, we acquired Lemon, a mobile wallet innovator. In connection with this acquisition, we launched our new LifeLock mobile application. The aggregate purchase price consisted of approximately $42,369 of cash paid at the closing (net of cash acquired of $3,315).  We preliminarily allocated the total purchase consideration to the assets acquired and liabilities assumed at their estimated fair values as of the date of acquisition, as determined by management, and, with respect to identifiable intangible assets, by management with the assistance of a valuation provided by a third-party valuation firm. We recorded the excess of the purchase price over the amounts allocated to assets acquired and liabilities assumed as goodwill in our consumer segment.
	The allocation of the purchase price of the acquired assets and liabilities as of December 31, 2013 was based on provisional measurements of fair value as determined by management.  Subsequent to the filing of our Annual Report on Form 10-K for the fiscal year ended December 31, 2013, we determined that approximately $4,988 of Lemon’s net operating loss carryforwards would expire as a result of limitations under Section 382 of the Internal Revenue Code.  As such, we reduced deferred tax assets, net – noncurrent by $2,033, increasing goodwill.  This adjustment has been reflected in the December 31, 2013 balances of deferred tax assets, net – noncurrent and goodwill in the accompanying condensed consolidated balance sheets.
	We accounted for this acquisition using the acquisition method in accordance with Accounting Standards Codification, or ASC, 805, Business Combinations. Accordingly, we allocated the purchase price of the acquired assets and liabilities based on their estimated fair values as of the acquisition date as summarized in the following table:
	Net assets assumed	$	3,184
	Deferred tax assets, net – noncurrent		9,896
	Intangible assets acquired		3,880

	As of March 31, 2014, we did not consider any of our marketable securities to be other-than-temporarily impaired. When evaluating our investments for other-than-temporary impairment, we review factors such as the length of time and extent to which fair value has been below its cost basis, the financial condition of the issuer, our ability and intent to hold the security and whether it is more likely than not that we will be required to sell the investment before recovery of its cost basis.

In our consumer segment, we offer proactive identity theft protection services to our members on an annual or monthly subscription basis. In our enterprise segment, we offer fraud and risk solutions to our enterprise customers.
	Financial information about our segments during the three-month period ended March 31, 2014 and as of March 31, 2014 was as follows:

Income Taxes	'
	Income taxes for the interim periods presented have been included in the accompanying condensed consolidated financial statements on the basis of an estimated annual effective tax rate.  Based on an estimated annual effective tax rate and discrete items, the estimated income tax (benefit) expense from operations for the three-month periods ended March 31, 2014 and 2013 was approximately $(3,548) and $150, respectively.  The determination of the interim period income tax provision utilizes the effective tax rate method, which requires us to estimate certain annualized components of the calculation of the income tax provision, including the annual effective tax rate by entity and jurisdiction.
	In the fourth quarter of 2013, in connection with the acquisition of Lemon and the preliminary purchase price allocation, we analyzed Lemon’s prior ownership changes, including the change which arose as a result of our acquisition of Lemon. As a result of the preliminary analysis, we estimated that none of Lemon’s net operating loss carryforwards would expire as a result of limitations under Section 382 of the Internal Revenue Code. Subsequent to the filing of our Annual Report on Form 10-K for the fiscal year ended December 31, 2013, we received responses from certain former shareholders who had held a 5% or greater ownership interest in Lemon prior to the acquisition and determined that due to the ownership changes of those former shareholders, approximately $4,988 of Lemon’s net operating loss carryforwards will expire solely as a result of the Section 382 limitations. As such, we retrospectively adjusted our preliminary purchase price allocation to reflect this information.

	As part of our consumer services, we offer 24x7x365 member service support. If a member’s identity has been compromised, our member service team and remediation specialists will assist the member until the issue has been resolved. This includes our $1 million service guarantee, which is backed by an identity theft insurance policy, under which we will spend up to $1 million to cover certain third-party costs and expenses incurred in connection with the remediation, such as legal and investigatory fees. This insurance also covers certain out-of-pocket expenses, such as loss of income, replacement of fraudulent withdrawals, and costs associated with child and elderly care, travel, and replacement of documents. While we have reimbursed members for claims under this guarantee, the amounts in aggregate for the three-month periods ended March 31, 2014 and 2013 were not material.
	In September 2012, Denise Richardson filed a complaint against our company and Todd Davis. Ms. Richardson claims that she was improperly classified as an independent contractor instead of an employee and that we breached the terms of an alleged employment agreement. Ms. Richardson claims she is entitled to equitable relief, compensatory damages, liquidated damages, statutory penalties, punitive damages, interest, costs, and attorneys’ fees. On March 31, 2014, our motion to dismiss was granted in part and denied in part with the court dismissing nine of the ten counts that were subject to the motion to dismiss, including the single count against Mr. Davis.  On April 23, 2014, Ms. Richardson filed an amended complaint against our company and Mr. Davis again claiming that she was improperly classified as an independent contractor instead of an employee and that we breached the terms of an alleged employment agreement. Ms. Richardson claims she is entitled to equitable relief, compensatory damages, liquidated damages, statutory penalties, punitive damages, interest, costs, and attorneys’ fees.  We have until May 14, 2014 to respond to the most recently filed complaint.
	On March 3, 2014, Dawn B. Bien, representing herself and seeking to represent a class of persons who acquired our securities from February 26, 2013 to February 19, 2014, inclusive, or the Class Period, filed a complaint in United States District Court for the District of Arizona against us, Todd Davis, and Chris Power.  We refer to this complaint as the Bien Complaint.  The Bien Complaint alleges that we and Messrs. Davis and Power, in violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, or the Exchange Act,  disseminated materially false or misleading information, or failed to disclose material facts during the Class Period in connection with our business and our operational and compliance policies, including our and Mr. Davis’s compliance with the  Stipulated Final Judgment and Order for Permanent Injunction and Other Equitable Relief entered into in March 2010 with the Federal Trade Commission, or the FTC Order, wherein we settled allegations by the Federal Trade Commission challenging certain of our advertising and marketing.  The Bien Complaint also contends that as a result of alleged violations of governmental laws, regulations, and the FTC Order, our financial statements were materially false and misleading at all relevant times.  The Bien Complaint seeks certification as a class action, compensatory damages, and attorneys’ fees and costs. On March 10, 2014, Joseph F. Scesny, representing himself and seeking to represent a class of persons who acquired our securities from February 26, 2013 to February 19, 2014, inclusive, filed a complaint in United States District Court for the District of Arizona against us, Todd Davis, and Chris Power.  We refer to this complaint as the Scesny Complaint. The Scesny Complaint is substantially similar to the Bien Complaint and seeks substantially similar relief. We anticipate that the Bien Complaint and Scesny Complaint will be consolidated into one action and that the court will select a lead plaintiff as provided by the federal securities laws governing purported class action cases.
	On March 13, 2014, we received a request from the Federal Trade Commission, or the FTC, for documents and information related to our compliance with the FTC Order.   Prior to our receipt of the FTC’s request, we met with FTC Staff on January 17, 2014, at our request, to discuss issues regarding allegations that have been asserted in a whistleblower claim against us relating to our compliance with the FTC Order.  We are cooperating with the FTC in regards to its request and are currently in the process of providing the documents and information requested by the FTC.
	On March 20, 2014, Michael D. Peters filed a complaint in United States District Court for the District of Arizona against our company, Kim Jones, and Cristy Schaan.  Mr. Jones is not affiliated with us.  Ms. Schaan is our Chief Information Security Officer.  In his complaint, Mr. Peters alleges that we violated the whistleblower protection provisions of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, and the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, by terminating Mr. Peters’ employment as a result of alleged disclosures that he made to us, and that Ms. Schaan defamed Mr. Peters.  Mr. Peters seeks from us two times his back pay, two times the value of certain stock options and bonus, moving expenses, damages for emotional harm and anxiety, damages for harm to reputation, litigation costs including attorneys’ fees, and interest, and seeks from Ms. Schaan actual damages, punitive damages, and interest.  On April 21, 2014, we filed an answer, affirmative defenses, and counterclaims, answering Mr. Peters’ claim under the Sarbanes-Oxley Act and asserting counterclaims against Mr. Peters for fraud, negligent misrepresentation, breach of contract, and unjust enrichment, based on our allegations that we were induced to hire Mr. Peters by his false statements and misrepresentations regarding his employment history and seeking to recover actual and consequential damages, punitive damages, attorneys’ fees, and the $15 signing bonus paid to Mr. Peters.  Mr. Peters’ response to the counterclaim is due on May 15, 2014.  On April 21, 2014, we also filed a motion to dismiss Mr. Peters’ claim under the Dodd-Frank Act.  Mr. Peters’ response to that motion to dismiss is due on May 15, 2014.  On April 25, 2014, Ms. Schaan filed a motion to dismiss Mr. Peters’ claim against her.  Mr. Peters’ response to that motion to dismiss is due on May 19, 2014.
	We are subject to other legal proceedings and claims that have arisen in the ordinary course of business. Although there can be no assurance as to the ultimate disposition of these matters and the proceedings disclosed above, we believe, based upon the information available at this time, that a material adverse outcome related to the matters is neither probable nor estimable.

Basis of Presentation	'
	Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States, or U.S. GAAP, and applicable rules and regulations of the Securities and Exchange Commission, or SEC, regarding interim financial reporting. Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013.
	The condensed consolidated balance sheet as of December 31, 2013 included herein was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by U.S. GAAP.
	The accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, but are not necessarily indicative of the result of operations to be anticipated for the entire year ending December 31, 2014 or any future period.
Basis of Consolidation	'
	Basis of Consolidation
	The condensed consolidated financial statements include our accounts and those of our wholly-owned subsidiaries. We eliminate all intercompany balances and transactions, including intercompany profits, and unrealized gains and losses in consolidation.
Use of Estimates	'
	Use of Estimates
	The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires us to make certain estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. We base our estimates on historical experience, current business factors, and various other assumptions that we believe are necessary to consider in forming a basis for making judgments about the carrying values of assets and liabilities, the recorded amounts of revenue and expenses, and the disclosure of contingent assets and liabilities.
Significant Accounting Policies	'

Recently Issued Accounting Standards	'
	Recently Issued Accounting Standards
	In April 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update (ASU) No. 2014-08, Reporting Discontinued Operations and Disclosures of Components of an Entity, which changes the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements.  The updated guidance defines discontinued operations as a disposal of a component or group of components that is disposed of or is classified as held for sale and represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results and expands the disclosure requirements for discontinued operations and adds new disclosures for individually significant dispositions that do not qualify as discontinued operations.  ASU No. 2014-08 is effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2014.  ASU No. 2014-08 would be applied to any future applicable transaction.
