Organization Consolidation And Presentation Of Financial Statements [Abstract]
Description of Business and Significant Accounting Policies	1. Description of Business and Significant Accounting Policies Description of Business MobileIron, Inc., and its wholly owned subsidiaries collectively, the “Company”, “we”, “us” or “our”, provides a purpose-built mobile IT platform that enables enterprises to manage and secure mobile applications, content and devices while providing their employees with device choice, privacy and a native user experience. We were incorporated in Delaware in July 2007 and are headquartered in Mountain View, California, with additional sales and support presence in North America, Europe, the Middle East, Asia and Australia. Initial Public Offering In June 2014, we completed our initial public offering, or our IPO, in which we issued and sold 12,777,777 shares of common stock, including 1,666,666 million shares of common stock sold pursuant to the full exercise of the underwriters’ over-allotment option, at a price of $9.00 per share. We received aggregate proceeds of $107.0 million from the sale of shares of common stock, net of underwriters’ discounts and commissions, but before deducting offering expenses of approximately $4.1 million. Upon the closing of the initial public offering, all shares of our outstanding convertible preferred stock automatically were converted into 49,646,975 shares of common stock. Basis of Presentation and Consolidation The accompanying unaudited condensed consolidated financial statements as of June 30, 2015 and for the three and six months ended June 30, 2015 and 2014 have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP, for interim financial statements and pursuant to the rules and regulations of the Securities and Exchange Commission, or the SEC, and include the accounts of our wholly owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. Certain information and footnote disclosures in this Form 10-Q normally included in annual financial statements prepared in accordance with U.S. GAAP and pursuant to the rules and regulations of the SEC have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary for a fair presentation of our balance sheet as of June 30, 2015 and our operating results for the three and six months ended June 30, 2015 and 2014 , and our cash flows for the six months ended June 30, 2015 and 2014 . Operating results for the three and six months ended June 30, 2015 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2015 . The condensed consolidated balance sheet as of December 31, 2014 has been derived from the audited consolidated financial statements as of that date but does not include all the footnotes required by U.S. GAAP for complete financial statements. The accompanying unaudited condensed consolidated financial statements and related financial information should be read in conjunction with our audited financial statements and related notes thereto for the year ended December 31, 2014, included in our Annual Report on Form 10-K filed with the SEC on February 27, 2015. Foreign Currency Translation Our reporting currency is the U.S. dollar. The functional currency of all our international operations is the U.S. dollar. All monetary asset and liability accounts are translated into U.S. dollars at the period-end rate, nonmonetary assets and liabilities are translated at historical exchange rates, and revenue and expenses are translated at the weighted-average exchange rates in effect during the period. Translation adjustments arising are recorded as foreign currency gains (losses) in the consolidated statements of operations. We recognized a foreign currency loss of approximately $83,000 and $93,000 for the three months ended June 30, 2015 and 2014 , respectively, and approximately $257,000 and $169,000 for the six months ended June 30, 2015 and 2014, respectively, in other expense—net in our condensed consolidated statements of operations. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. These estimates include, but are not limited to, revenue recognition, stock-based compensation, stock-settled bonus expense, goodwill, intangible assets and accounting for income taxes. Actual results could differ from those estimates. Concentrations of Credit Risk Financial instruments that potentially subject us to a concentration of credit risk consist of cash, money market funds and fixed income investments. Although we deposit our cash with multiple financial institutions, our deposits, at times, exceed federally insured limits. We invest in fixed income securities that are of high-credit quality. Substantially all of our money market funds, or $20.7 million, are held in a two funds that are rated “AAA.” We generally do not require collateral or other security in support of accounts receivable. Allowances are provided for individual accounts receivable when we become aware of a customer’s inability to meet its financial obligations, such as in the case of bankruptcy, deterioration in the customer’s operating results, or change in financial position. If circumstances related to customers change, estimates of the recoverability of receivables would be further adjusted. We also consider broader factors in evaluating the sufficiency of our allowances for doubtful accounts, including the length of time receivables are past due, significant one-time events and historical experience. As of June 30, 2015 and December 31, 2014 we have an allowance for doubtful accounts of $692,000 and $550,000 , respectively. One reseller accounted for 17% of total revenue ( 1% as an end customer) and 18% of total revenue ( 1% as an end customer) for the three and six months ended June 30, 2015 , respectively, and for 26% of total revenue (2% as an end customer) and 25% of total revenue (1% as an end customer) for the three and six months ended June 30, 2014, respectively. The same reseller accounted for 27% and 16% of net accounts receivable as of June 30, 2015 and December 31, 2014 , respectively. There were no other resellers or end-user customers that accounted for 10% or more as a percentage of our revenue or net accounts receivable for any period presented. Segments We have one reportable segment. Summary of Significant Accounting Policies Revenue Recognition We derive revenue principally from software-related arrangements consisting of perpetual software licenses, post-contract customer support for such licenses, or PCS or software support, including when and if available updates, and professional services such as consulting and training services. We also offer our software as term-based licenses and cloud-based arrangements. In addition, we install our software on servers that we ship to customers. We begin to recognize revenue when (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred or services have been provided, (iii) the sales price is fixed or determinable, and (iv) collection of the related receivable is probable. If collection is not considered probable, revenue is recognized only upon collection. Signed agreements, including by electronic acceptance, are used as evidence of an arrangement. Delivery is considered to occur when we provide a customer with a link and credentials to download our software. Delivery of a hardware appliance (an “appliance”) is considered to occur when title and risk of loss has transferred to the customer, which typically occurs when appliances are delivered to a common carrier. Delivery of services occurs when performed. Prior to January 1, 2013, we had not established vendor specific objective evidence, or VSOE, of fair value for any of the elements in our multiple-element arrangements. As of January 1, 2013, we determined that we had sufficient history to establish VSOE of fair value for PCS and professional services. Prior to January 1, 2013, we did not have VSOE of fair value for our software-related undelivered elements due to limited history of stand-alone sales transactions and inconsistency in pricing. We established VSOE of fair value when we had a substantial majority of stand-alone sales transactions of software support and services pricing within a narrow pricing band. In our VSOE analysis, we generally include stand-alone sales transactions completed during a rolling 12 month period unless a shorter period is appropriate due to changes in our pricing structure. We typically enter into multiple-element arrangements with our customers in which a customer may purchase a combination of software on a perpetual or subscription license, PCS, and professional services. The professional services are not considered essential to the functionality of the software. All of these elements are considered separate units of accounting. Our standard agreements do not include rights for customers to cancel or terminate arrangements or to return software to obtain refunds. We use the residual method to recognize revenue when a perpetual license arrangement includes one or more elements to be delivered at a future date provided the following criteria are met: (i) VSOE of fair value does not exist for one or more of the delivered items but exists for all undelivered elements, (ii) all other applicable revenue recognition criteria are met and (iii) the fair value of all of the undelivered elements is less than the arrangement fee. VSOE of fair value is based on the normal pricing practices for those products and services when sold separately by us and contractual customer renewal rates for post-contract customer support services. Under the residual method, the fair value of the undelivered elements is deferred and the remaining portion of the arrangement fee is recognized as revenue in the period in which it was earned. If evidence of the fair value of one or more undelivered elements does not exist, then the revenue is deferred and recognized when delivery of those elements occurs, or when fair value can be established, or ratably over the PCS period if the only undelivered element is PCS—we refer to these deferred revenue elements as the “Deferred Portion.” Revenue from subscriptions to our on-premise term licenses, arrangements where perpetual and subscriptions to our on-premise term licenses are sold together, and subscriptions to our cloud service are recognized ratably over the contractual term for all periods presented and are included as a component of subscription revenue within our consolidated statements of operations. We refer to arrangements where perpetual and subscriptions to our on-premise term licenses are sold together as “Bundled Arrangements.” Occasionally, we enter into multiple-element arrangements with our customers in which a customer may purchase a combination of software on a perpetual or term basis, PCS, professional services, and appliances. We generally provide the appliances and software upon the commencement of the arrangement and provide software-related elements throughout the support period. We account for appliance-bundled arrangements under the revised accounting standard related to multiple-element arrangements, Accounting Standard Update, or ASU, No. 2009-13, Multiple Element Arrangements , and determine the revenue to be recognized based on the standard’s fair value hierarchy and then determine the value of each element in the arrangement based on the relative selling price of the arrangement. Amounts related to appliances are generally recognized upon delivery with the remaining consideration allocated to software and software-related elements, which are recognized as described elsewhere in this policy. Revenue from PCS is recognized ratably over the support term and is included as a component of software support and service revenue within the consolidated statements of operations. Revenue related to professional services is recognized upon delivery and is included as a component of software support and services revenue within the consolidated statements of operations. Prior to establishing VSOE of fair value for PCS and professional services on January 1, 2013, we recognized revenue for multiple element software and software-related arrangements ratably from the date of service commencement over the contractual term of the related PCS arrangement. After January 1, 2013, the deferred revenue related to these arrangements continues to be recognized ratably over the remaining contractual term of the PCS arrangement. Approximately $616,000 and $1.4 million of perpetual license revenue in three months ended 2015 and 2014 , respectively, and approximately $1.4 and $3.0 million of perpetual license revenue in the six months ended June 30, 2015 and 2014 respectively, related to sales made prior to January 1, 2013. Approximately $758,000 and $2.1 million of deferred revenue as of June 30, 2015 and December 31, 2014 , respectively, related to sales made prior to January 1, 2013. We allocated the revenue from all multiple-element arrangements entered into prior to the establishment of VSOE of fair value for our PCS and professional services to each respective revenue caption using our best estimate of value of each element based on the facts and circumstances of the arrangements, our go-to-market strategy, price list and discounts from price list as applicable. We believe that the allocation between the revenue captions allows for greater transparency and comparability of revenue from period to period even though VSOE of fair value may not have existed at that time. Appliance revenue was less than 10% of total revenue for all periods presented and is included as a component of perpetual license revenue within the consolidated statements of operations. Generally, sales made through resellers are fulfilled to the end customer and processed in the same period. The inventory of licenses held by the resellers was immaterial for all periods presented. Shipping charges and sales tax billed to partners are excluded from revenue. Sales commissions and other incremental costs to acquire contracts are also expensed as incurred and are recorded in sales and marketing expense. For all arrangements, any revenue that has been deferred and is expected to be recognized beyond one year is classified as long-term deferred revenue in the consolidated balance sheets. Cash Equivalents We consider all highly liquid investments with an original maturity of three months or less to be cash equivalents. As of June 30, 2015 and December 31, 2014 cash and cash equivalents consist of cash deposited with banks, money market funds and investments that mature within three months of their purchase. Held-To-Maturity Investments We determine the appropriate classification of our fixed income investments at the time of purchase and reevaluate their classifications each reporting period. Investments are classified as held-to-maturity since the Company has positive intent and the ability to hold the securities to maturity. Held-to-maturity securities are stated at amortized cost. Comprehensive Loss Comprehensive loss includes all changes in equity (net assets) during a period from non-owner sources. For the three and six months ended June 30, 2015 and 2014 , there were no differences between net loss and comprehensive loss. Therefore, the consolidated statements of comprehensive loss have been omitted. Net Loss per Share of Common Stock Basic net loss per common share is calculated by dividing the net loss by the weighted-average number of common shares outstanding during the period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common shares and potentially dilutive securities outstanding for the period determined using the treasury-stock and if-converted methods. For purposes of the diluted net loss per share calculation, unvested restricted stock and stock options are considered to be potentially dilutive securities. Because we have reported a net loss for the three and six months ended June 30, 2015 and 2014 , the number of shares used to calculate diluted net loss per common share is the same as the number of shares used to calculate basic net loss per common share for those periods presented because the potentially dilutive shares would have been anti-dilutive if included in the calculation. Inventory We have appliances (industry standard hardware servers available from multiple vendors) that are available for customers to purchase, on which we will preinstall our software prior to shipment. Inventory is stated at the lower of cost or net realizable value. We value our inventory using the first-in, first-out method. Appropriate consideration is given to obsolescence, excessive levels, deterioration and other factors in evaluating net realizable value—such adjustments were not material for any period presented. The entire inventory is comprised of finished goods. As of June 30, 2015 and December 31, 2014 , we had inventory of $313,000 and $528,000 , respectively, which is included in prepaid expenses and other current assets in the consolidated balance sheets. Software Development Costs Incurred in Connection with Software to be Sold or Marketed The costs to develop new software products and enhancements to existing software products are expensed as incurred until technological feasibility has been established. We consider technological feasibility to have occurred when all planning, designing, coding and testing have been completed according to design specifications. Once technological feasibility is established, any additional costs would be capitalized. We believe our current process for developing software is essentially completed concurrent with the establishment of technological feasibility, and accordingly, no costs have been capitalized. Internal Use Software We capitalize costs incurred during the application development stage related to our internally used software. Such costs are primarily incurred by third party vendors and consultants. Costs related to preliminary project activities and post-implementation activities are expensed as incurred. Amounts capitalized in all periods presented were not significant. All software development costs incurred in connection with our cloud offering, or SaaS are also sold or marketed to partners or end customers, therefore we start capitalizing costs when technological feasibility is achieved. No costs were capitalized in any periods presented as we believe that our current process for developing software is essentially completed concurrent with the establishment of technological feasibility. Property and Equipment Property and equipment are stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives, determined to be three years for computers and equipment and software, five years for furniture and fixtures, and the lesser of the remaining lease term or estimated useful life for leasehold improvements. Expenditures for repairs and software support are charged to expense as incurred. Upon disposition, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is reflected as operating expenses in the consolidated statements of operations. Goodwill and Intangible Assets We record the excess of the acquisition purchase price over the fair value of the tangible and identifiable intangible assets acquired as goodwill. We perform an impairment test of our goodwill in the third quarter of our fiscal year, or more frequently if indicators of potential impairment arise. We have a single reporting unit and consequently evaluate goodwill for impairment based on an evaluation of the fair value of the Company as a whole. We record purchased intangible assets at their respective estimated fair values at the date of acquisition. Purchased intangible assets are being amortized using the straight-line method over their remaining estimated useful lives, which range from three to five years. We evaluate the remaining useful lives of intangible assets on a periodic basis to determine whether events or circumstances warrant a revision to the remaining estimated amortization period. Long-Lived Assets with Finite Lives Long-lived assets are reviewed for possible impairment whenever events or circumstances indicate that the carrying amount of these assets may not be recoverable. We evaluate the recoverability of each of our long-lived assets, including purchased intangible assets and property and equipment, by comparison of its carrying amount to the future undiscounted cash flows we expect the asset to generate. If we consider the asset to be impaired, we measure the amount of any impairment as the difference between the carrying amount and the fair value of the impaired asset. Stock-Based Compensation We use the estimated grant-date fair value method of accounting in accordance with Accounting Standards Codification, or ASC, Topic 718 Compensation—Stock Compensation . Fair value is determined using the Black-Scholes Model using various inputs, including our estimates of expected volatility, term and future dividends. We estimated the forfeiture rate for the three and six months ended June 30, 2015 and the corresponding periods of 2014 based on our historical experience for annual grant years where the majority of the vesting terms have been satisfied. We recognize compensation costs for awards with service and performance vesting conditions on an accelerated method over the requisite service period of the award. For stock options, restricted stock units or restricted stock grants with no performance condition, we recognize compensation costs on a straight-line basis over the requisite service period of the award, which is generally the vesting term of four years . Research and Development Research and development, or R&D, costs are charged to expense as incurred. Advertising Advertising costs are expensed and included in sales and marketing expense when incurred. Advertising expense for the three and six months ended June 30, 2015 and 2014 was not significant. Income Taxes We account for income taxes in accordance with ASC Topic 740, Income Taxes , under which deferred tax liabilities and assets are recognized for the expected future tax consequences of temporary differences between financial statement carrying amounts and the tax basis of assets and liabilities and net operating loss and tax credit carryforwards. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. We use a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. A tax position is recognized when it is more likely than not that the tax position will be sustained upon examination, including resolution of any related appeals or litigation processes. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority. The standard also provides guidance on derecognition of tax benefits, classification on the balance sheet, interest and penalties, accounting in interim periods, disclosure and transition. Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board, or FASB, or other standard setting bodies and adopted by us as of the specified effective date. Unless otherwise discussed, the impact of recently issued standards that are not yet effective will not have a material impact on our financial position or results of operations upon adoption. In May 2014, the FASB, jointly with the International Accounting Standards Board, issued a comprehensive new standard on revenue recognition from contracts with customers. The standard’s core principle is that a reporting entity will 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. In applying this new guidance to contracts within its scope, an entity will: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation. Additionally, this new guidance will require significantly expanded disclosures about revenue recognition. As clarified by the FASB on July 9, 2015, provisions of this new standard are effective for annual reporting periods (including interim reporting periods within those annual periods) beginning after December 15, 2017. Early adoption is permitted for annual reporting periods (including interim reporting periods within those annual periods) beginning after December 15, 2016. Entities have the option of using either a full retrospective or a modified retrospective approach to adopt this new guidance. We are currently evaluating the potential effect on our consolidated financial statements from adoption of this standard.

Fair Value Disclosures [Abstract]
Fair Value Measurement	3. Fair Value Measurement With the exception of our held-to-maturity fixed income investments, we report all financial assets and liabilities and nonfinancial assets and liabilities that are recognized or disclosed at fair value in the consolidated financial statements on a recurring basis in accordance with ASC 820 (formerly FASB Statement No. 157, Fair Value Measurements ). ASC 820 defines fair value 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, which are required to be recorded at fair value, we consider the principal or most advantageous market in which we would transact and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as inherent risk, transfer restrictions and credit risk. ASC 820 also establishes a fair value hierarchy, which prioritizes the inputs to valuation techniques used to measure fair value into three levels. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is available and significant to the fair value measurement. ASC 820 establishes and prioritizes three levels of inputs that may be used to measure fair value: — Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities. — Level 2—Inputs are quoted prices for similar assets and liabilities in active markets or inputs other than quoted prices that are observable for the assets or liabilities, either directly or indirectly through market corroboration, for substantially the full term of the financial instruments. — Level 3—Inputs are unobservable inputs based on our own assumptions used to measure assets and liabilities at fair value. The inputs require significant management judgment or estimation. Our financial assets that are carried at fair value include cash and money market funds. We had no other financial liabilities, or nonfinancial assets and liabilities that were required to be measured at fair value on a recurring basis, or that were measured at fair value as of June 30, 2015 or December 31, 2014 . Our financial instruments measured at fair value as of June 30, 2015 and December 31, 2014 were as follows (in thousands): As of June 30, 2015 (in thousands) Level 1 Level 2 Level 3 Total Money market funds $ $ — $ — $ Corporate debt securities — — Commercial paper — — Securities and obligations of U.S. government agencies — — Total $ $ $ — $ As of December 31, 2014 (in thousands) Level 1 Level 2 Level 3 Total Money market funds $ $ — $ — $ Corporate debt securities — — Commercial paper — — Securities and obligations of U.S. government agencies — — Total $ $ $ — $

Investments	4. Investments Our portfolio of fixed income securities consists of commercial paper, corporate debt securities and securities and obligations of U.S. government agencies. All our investments in fixed income securities are classified as held-to-maturity. These investments are carried at amortized cost.

Actual maturities may differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties.

In order to determine whether a decline in fair value is other-than-temporary, we evaluate, among other factors: the duration and extent to which the fair value has been less than the carrying value; our financial condition and business outlook, including key operational and cash flow metrics, current market conditions and future trends in our industry; our relative competitive position within the industry; and our intent and ability to retain the investment for a period of time sufficient to allow for any anticipated recovery in fair value. A decline in the fair value of the security below amortized cost that is deemed other-than-temporary is charged to earnings, resulting in the establishment of a new cost basis for the affected securities. In the three and six months ended June 30, 2015 , we had an insignificant amount of unrealized gains or losses, and we did not recognize any other-than-temporary impairments .

Business Combination Disclosure [Text Block]	5. Acquisition In April 2014, we completed the acquisition of certain assets of Averail Corporation, or Averail, a privately-held content security-oriented software company, for 276,466 shares of common stock and the assumption of certain liabilities. The assets acquired provide additional features in our Docs Work product. We obtained control of the specific assets acquired and liabilities assumed of Averail through the issuance of 276,466 shares of our common stock to the pre-existing Averail shareholders. Included in the total, 43,612 shares are subject to a holdback provision for standard representations and warranties and will be held in escrow for 18 month from the date of acquisition. The aggregate purchase price of the transaction was approximately $2.0 million, net of liabilities assumed. In connection with this acquisition, 206,463 of these shares were distributed to two Averail investors that are also MobileIron investors. In addition, one of our board members served as a director of Averail. The aggregate value of the securities issued to our investors was approximately $1.5 million. The total consideration for this transaction was approximately $2.0 million and consisted of the following (in thousands except share data): Common stock issued (232,854 shares) $ Holdback common stock (43,612 shares) Total Consideration $ Transaction costs associated with the acquisition were $167,000 , all of which we expensed in three and six months ended June 30, 2014, and are included in general and administrative expense in the accompanying unaudited consolidated statements of operations . We accounted for the Averail acquisition as a business combination. The assets acquired and liabilities assumed were recorded at fair market value. The excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired was recorded as goodwill. The goodwill generated from this business combination was primarily related to value placed on the employee workforce and expected synergies and will not be deductible for tax purposes. The purchase price was allocated as follows (in thousands): Technology – intangible asset $ Goodwill Liabilities assumed Net assets acquired $ The technology intangible asset is being amortized over a period of four years and is reported net of accumulated amortization in the accompanying unaudited condensed consolidated balance sheets as of June 30, 2015 and December 31, 2014. Amortization expense related to the intangible asset was $100,000 in each of the three months ended June 30, 2015 and 2014 and $200,000 and $100,000 in the six months ended June 30, 2015 and 2014, all of which was included in cost of revenue. The amount of revenue and earnings of Averail since the acquisition date are included in the condensed consolidated statements of operations and pro forma results of operations for the acquisition have not been presented because the effect of the acquisition was not significant to our financial results.

Amounts borrowed accrue interest at a floating per annum rate equal to the prime rate. A default interest rate shall apply during an event of default at a rate per annum equal to 5% above the otherwise applicable interest rate. The line of credit is collateralized by substantially all of our assets, except intellectual property, and requires us to comply with working capital, net worth and other nonfinancial covenants, including limitations on indebtedness and restrictions on dividend distributions, among others, and the borrowing capacity is limited to eligible accounts receivable. We are required to maintain an adjusted quick ratio (defined as the ratio of current assets to current liabilities minus deferred revenue) of at least 1.25 .

Share Based Awards	10. Share Based Awards 2008 Plan The 2008 Stock Plan, or 2008 Plan, which expired on June 12, 2014 , provided for the grant of incentive and nonstatutory stock options to employees, nonemployee directors and consultants of the Company. Options granted under the 2008 Plan generally become exercisable within three to four years following the date of grant and expire 10 years from the date of grant. When options are subject to our repurchase right, we may buy back any unvested shares at their original exercise price in the event of an employee’s termination prior to full vesting. Our 2008 Plan was terminated following the date our 2014 Equity Incentive Plan, or the 2014 Plan, became effective. Any outstanding stock awards under our 2008 Plan will continue to be governed by the terms of our 2008 Plan and applicable award agreements. 2014 Equity Incentive Plan Our board of directors adopted our 2014 Plan on April 17, 2014, and our stockholders subsequently approved the 2014 Plan on May 27, 2014. The 2014 Plan became effective on the date that our registration statement was declared effective by the SEC. The 2014 Plan is the successor to and continuation of our 2008 Plan. Upon the effective date of the 2014 Plan, no further grants can be made under our 2008 Plan. Our 2014 Plan provides for the grant of incentive stock options, or ISOs, within the meaning of Section 422 of the Internal Revenue Code, or the Code, to our employees and our parent and subsidiary corporations’ employees, and for the grant of nonstatutory stock options, or NSOs, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance-based stock awards, and other forms of equity compensation to our employees, directors and consultants. Additionally, our 2014 Plan provides for the grant of performance cash awards to our employees, directors and consultants. The initial number of shares of our common stock available to be issued under our 2014 Plan was 8,142,857 , which number of shares will be increased by any shares subject to stock options or other stock awards granted under the 2008 Plan that would have otherwise returned to our 2008 Plan (such as upon the expiration or termination of a stock award prior to vesting), not to exceed 16,312,202 . Additionally, the number of shares of our common stock reserved for issuance under our 2014 Plan will automatically increase on January 1 of each year, beginning on January 1, 2015 and continuing through and including January 1, 2024, by 5% of the total number of shares of our capital stock outstanding on December 31 of the preceding calendar year, or a lesser number of shares determined by our board of directors. On January 1, 2015, we increased the number of shares of common stock reserved for issuance under our 2014 Plan by 3,818,242 shares. 2014 Employee Stock Purchase Plan Our board of directors adopted our 2014 Employee Stock Purchase Plan, or ESPP, on April 17, 2014, and our stockholders subsequently approved the ESPP on May 27, 2014. The ESPP became effective immediately upon the execution and delivery of the underwriting agreement related to our IPO. The purpose of the ESPP is to secure the services of new employees, to retain the services of existing employees and to provide incentives for such individuals to exert maximum efforts toward our success and that of our affiliates. The ESPP is intended to qualify as an “employee stock purchase plan” within the meaning of Section 423 of the Code. The ESPP permits eligible employees to purchase our common stock through payroll deductions, which may not exceed 15% of the employee’s base compensation. Stock may be purchased under the plan at a price equal to 85% of the fair market value of our common stock on either the first day of the offering or the last day of the applicable purchase period, whichever is lower. The initial number of shares of our common stock initially reserved for issuance under our ESPP was 2,071,428 shares. The number of shares of our common stock reserved for issuance under our ESPP will increase automatically each year, beginning on January 1, 2015 and continuing through and including January 1, 2024, by the lesser of (i) 1% of the total number of shares of our common stock outstanding on December 31 of the preceding calendar year; (ii) 2,142,857 shares of common stock; or (iii) such lesser number as determined by our board of directors. Shares subject to purchase rights granted under our ESPP that terminate without having been exercised in full will not reduce the number of shares available for issuance under our ESPP. On January 1, 2015, we increased the number of shares available for issuance under the ESPP by 763,648 shares. Restricted Stock and Restricted Stock Units Restricted stock activity for the six months ended June 30, 2015 was as follows: Restricted Stock Time-based Time-and- performance based Total shares shares shares Unvested, December 31, 2014 Granted — — — Vested Cancelled/Forfeited — Unvested, June 30, 2015 For stock-based compensation expense, we measure the value of the restricted stock based on the fair value of our common stock on the date of grant. Our restricted stock grants may be subject to service only or service and performance-based vesting conditions. We expense the fair value of restricted stock grants with service only vesting conditions on a straight-line basis over the vesting period of the awards. For shares subject to service and performance conditions, we evaluate the probability of meeting the vesting conditions at the end of each reporting period to determine how much compensation expense to record. We amortize the fair value, net of estimated forfeitures, as stock-based compensation expense using the graded vesting method over the vesting periods of the awards. To the extent that actual results or updated estimates differ from our original estimates, the cumulative effect on current and prior periods of those changes will be recorded in the period those estimates are revised. In 2014 we began granting restricted stock units under our 2014 Plan. For stock-based compensation expense, we measure the value of the restricted stock units based on the fair value of our common stock on the date of grant. Our restricted stock unit grants are subject to service conditions and we expense the fair value of those shares on a straight-line basis over their vesting periods. Our restricted stock unit activity for the six months ended June 30, 2015 was as follows: Restricted Stock Units Weighted- Average Number of Grant Date Shares Fair Value Unvested, December 31, 2014 $ Granted Vested Forfeitures Unvested, June 30, 2015 $ In February 2015, our board of directors approved the 2015 Executive Bonus Plan and 2015 Non-executive Bonus Plan, or Bonus Plans, each effective as of January 1, 2015. The Bonus Plans are funded based on the achievement of certain Company metrics. Amounts earned under the Bonus Plans, if any, will be issued in shares of unrestricted common stock in the first quarter of 2016. Any shares issued from the Bonus Plans will reduce the 2014 Plan shares available for issuance. We record stock-based compensation expense related to the Bonus Plans, if any, over the service period of eligible employees based on forecasted performance relative to the Company metrics. To the extent that updated estimates of bonus expense differ from original estimates, the cumulative effect on current and prior periods of those changes will be recorded in the period those estimates are revised. For the three and six months ended June 30, 2015, no expense was recorded for the Bonus Plans. Stock Options Stock option activity under the 2008 Plan and 2014 Plan for the six months ended June 30, 2015 was as follows: Options Outstanding Weighted- Number of Average Aggregate Shares Weighted- Remaining Intrinsic Available Number of Average Contractual Value for Issuance Shares Exercise Price Term (Years) (In thousands) Balance—December 31, 2014 $ $ Authorized — Stock options granted Restricted stock units granted — Exercised (2) Stock options canceled Restricted stock units canceled — Repurchased — Balance—June 30, 2015 $ $ Vested and exercisable—June 30, 2015 $ Vested and expected to vest(1)—June 30, 2015 $ (1) Options expected to vest reflect an estimated forfeiture rate.

No shares were issued from the early exercise of stock options during the three and six months ended June 30, 2015 . Cash received from the early exercise of stock options is recorded in accrued expenses on the consolidated balance sheets and reclassified to stockholders’ equity as the options vest.

In May, 2015, we entered into an additional lease with WTA Middlefield LLC, effective as of May 14, 2015, for 43,466 square feet of office space in Mountain View, California. The lease term ends in 2023 and the total of the future lease payments is $18.4 million. Rent expense for the three months ended June 30, 2015 and 2014 was $1.1 million and $597,000 , respectively. Rent expense for the six months ended June 30, 2015 and 2014 was $2.2 million and $1.1 million, respectively. The aggregate future minimum lease payments under our agreements are as follows (in thousands): Year 2015 (remaining) $ 2016 2017 2018 2019 Thereafter Total $ Litigation We are involved in legal proceedings arising in the ordinary course of business, including intellectual property litigation. Although management currently is of the opinion that these matters will not have a material adverse effect on our condensed consolidated financial statements, the ultimate outcome of these matters cannot be predicted at this time, due to the inherent uncertainties in litigation. On November 14, 2012, Good Technology filed a lawsuit against us in federal court in the Northern District of California alleging false and misleading representations concerning their products and infringement of four patents held by them. In the complaint, Good Technology sought unspecified damages, attorney’s fees and a permanent injunction. On March 1, 2013, we counterclaimed against Good Technology for patent infringement of one of our patents , seeking similar relief . On October 13, 2014, the court issued a claims construction order. Good Technology responded by filing additional patent infringement suits against us in Delaware and internationally, as well as inter parties review proceedings. In each of these proceedings, Good Technology seeks to invalidate our patents and/or receive injunctive relief, as well as attorney’s fees. We have counterclaimed against them in the Delaware case on two of our next generation patents and seek similar relief. The Delaware case was recently transferred to the Northern District of California. On June 30, 2015, the court in the original Northern District of California case issued a summary judgment order invalidating one of Good Technology’s patents and holding that we did not infringe that patent as a matter of law. On August 4, 2015, a jury in the original Northern District of California case found that two of the three remaining Good Technology patents that were asserted in the case were invalid. The jury also found that we did not infringe any of Good Technology’s patents that were asserted in the case, and that Good Technology did not infringe our patent that was asserted in the case, which the jury also upheld as valid. As a result, neither we nor Good Technology was awarded damages in the case. Notwithstanding the summary judgment ruling and jury verdict in the original Northern District of California case, we and Good Technology continue to assert patent claims against each other in litigation and other proceedings, as described above. The final outcome, including our liability, if any, with respect to Good Technology’s on-going claims, is uncertain. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors. On May 1, 2015, a purported stockholder class action lawsuit was filed in the United States District Court for the Northern District of California against the Company and certain of its officers, captioned Panjwani v. MobileIron, Inc., et al. The action is purportedly brought on behalf of a putative class of all persons who purchased or otherwise acquired the Company’s securities between February 13, 2015, and April 22, 2015. It asserts claims for violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934.The complaint seeks, among other things, compensatory damages and attorney’s fees and costs on behalf of the putative class. The Company intends to defend the litigation vigorously. An estimate of a reasonably possible loss (or a range of loss) cannot be made in either the lawsuits that Good Technology has brought against us or the stockholder class action lawsuit at this time. Indemnification Under the indemnification provisions of our standard sales related contracts, we agree to defend and/or settle claims brought by third parties against our customers alleging that the customer’s use of our software infringes the third party’s intellectual property right, such as a patent right. These indemnification obligations are typically not subject to limitation; however if it is commercially impractical for us to either procure the right for the customer to continue to use our software or modify our software so that it’s not infringing, we typically can terminate the customer agreement and refund the customer a portion of the license fees paid, prorated over the three year period from initial delivery. We also on occasion indemnify our customers for other types of third party claims. In addition, we indemnify our officers, directors, and certain key employees while they are serving in such capacities in good faith. Through June 30, 2015, we have not received any written claim under any indemnification provision.

Segment Reporting [Abstract]
Segment Information	13. Segment Information We conduct business globally. Our chief operating decision maker (Chief Executive Officer) reviews financial information presented on a consolidated basis accompanied by information about revenue by geographic region for purposes of allocating resources and evaluating financial performance. We have one business activity, and there are no segment managers who are held accountable for operations, operating results and plans for levels, components or types of products or services below the consolidated unit level. Accordingly, we are considered to be in a single reportable segment and operating unit structure. Revenue by geographic region based on the billing address was as follows: Three Months Ended Six Months Ended June 30, June 30, (in thousands) 2015 2014 2015 2014 Revenue United States $ $ $ $ International Total $ $ $ $ We recognized revenue of $4.1 million, or 12% of total revenue , and $7.3 million , or 11% of total revenue , from customers with a billing address in Germany for the three and six months ended June 30, 2015, respectively. No country, except for the United States , exceeded 10% of the total revenue in the three or six months ended June 30, 2014. Substantially all of our long-lived assets were attributable to operations in the United States as of June 30, 2015 and December 31, 2014 .

Net Loss per Share	14. Net Loss per Share The following table sets forth the computation of basic and diluted net loss per share for the three and six months ended June 30, 2015 and 2014 (in thousands, except per share data): Three Months Ended Six Months Ended June 30, June 30, 2015 2014 2015 2014 Numerator: Net loss $ $ $ $ Denominator: Weighted–average shares outstanding Less: weighted average shares subject to repurchase Weighted–average shares used to compute basic and diluted net loss per share Basic and diluted net loss per share $ $ $ $ Basic net loss per share is computed by dividing the net loss by the weighted-average number of common shares outstanding for the period. Because we have reported a net loss for the three and six months ended June 30, 2015 and 2014 , the number of shares used to calculate diluted net loss per common share is the same as the number of shares used to calculate basic net loss per common share for those periods presented because the potentially dilutive shares would have been anti-dilutive if included in the calculation. The following potentially dilutive securities outstanding have been excluded from the computation of diluted weighted-average shares outstanding because such securities have an antidilutive impact due to losses reported (in common stock equivalent shares): June 30, June 30, 2015 2014 Options to purchase common stock and unvested restricted stock and restricted stock units

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Description of Business	Description of Business MobileIron, Inc., and its wholly owned subsidiaries collectively, the “Company”, “we”, “us” or “our”, provides a purpose-built mobile IT platform that enables enterprises to manage and secure mobile applications, content and devices while providing their employees with device choice, privacy and a native user experience. We were incorporated in Delaware in July 2007 and are headquartered in Mountain View, California, with additional sales and support presence in North America, Europe, the Middle East, Asia and Australia.
Initial Public Offering	Initial Public Offering In June 2014, we completed our initial public offering, or our IPO, in which we issued and sold 12,777,777 shares of common stock, including 1,666,666 million shares of common stock sold pursuant to the full exercise of the underwriters’ over-allotment option, at a price of $9.00 per share. We received aggregate proceeds of $107.0 million from the sale of shares of common stock, net of underwriters’ discounts and commissions, but before deducting offering expenses of approximately $4.1 million. Upon the closing of the initial public offering, all shares of our outstanding convertible preferred stock automatically were converted into 49,646,975 shares of common stock.
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The accompanying unaudited condensed consolidated financial statements as of June 30, 2015 and for the three and six months ended June 30, 2015 and 2014 have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP, for interim financial statements and pursuant to the rules and regulations of the Securities and Exchange Commission, or the SEC, and include the accounts of our wholly owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. Certain information and footnote disclosures in this Form 10-Q normally included in annual financial statements prepared in accordance with U.S. GAAP and pursuant to the rules and regulations of the SEC have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary for a fair presentation of our balance sheet as of June 30, 2015 and our operating results for the three and six months ended June 30, 2015 and 2014 , and our cash flows for the six months ended June 30, 2015 and 2014 . Operating results for the three and six months ended June 30, 2015 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2015 . The condensed consolidated balance sheet as of December 31, 2014 has been derived from the audited consolidated financial statements as of that date but does not include all the footnotes required by U.S. GAAP for complete financial statements. The accompanying unaudited condensed consolidated financial statements and related financial information should be read in conjunction with our audited financial statements and related notes thereto for the year ended December 31, 2014, included in our Annual Report on Form 10-K filed with the SEC on February 27, 2015.
Foreign Currency Translation	Foreign Currency Translation Our reporting currency is the U.S. dollar. The functional currency of all our international operations is the U.S. dollar. All monetary asset and liability accounts are translated into U.S. dollars at the period-end rate, nonmonetary assets and liabilities are translated at historical exchange rates, and revenue and expenses are translated at the weighted-average exchange rates in effect during the period. Translation adjustments arising are recorded as foreign currency gains (losses) in the consolidated statements of operations. We recognized a foreign currency loss of approximately $83,000 and $93,000 for the three months ended June 30, 2015 and 2014 , respectively, and approximately $257,000 and $169,000 for the six months ended June 30, 2015 and 2014, respectively, in other expense—net in our condensed consolidated statements of operations.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. These estimates include, but are not limited to, revenue recognition, stock-based compensation, stock-settled bonus expense, goodwill, intangible assets and accounting for income taxes. Actual results could differ from those estimates.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject us to a concentration of credit risk consist of cash, money market funds and fixed income investments. Although we deposit our cash with multiple financial institutions, our deposits, at times, exceed federally insured limits. We invest in fixed income securities that are of high-credit quality. Substantially all of our money market funds, or $20.7 million, are held in a two funds that are rated “AAA.” We generally do not require collateral or other security in support of accounts receivable. Allowances are provided for individual accounts receivable when we become aware of a customer’s inability to meet its financial obligations, such as in the case of bankruptcy, deterioration in the customer’s operating results, or change in financial position. If circumstances related to customers change, estimates of the recoverability of receivables would be further adjusted. We also consider broader factors in evaluating the sufficiency of our allowances for doubtful accounts, including the length of time receivables are past due, significant one-time events and historical experience. As of June 30, 2015 and December 31, 2014 we have an allowance for doubtful accounts of $692,000 and $550,000 , respectively. One reseller accounted for 17% of total revenue ( 1% as an end customer) and 18% of total revenue ( 1% as an end customer) for the three and six months ended June 30, 2015 , respectively, and for 26% of total revenue (2% as an end customer) and 25% of total revenue (1% as an end customer) for the three and six months ended June 30, 2014, respectively. The same reseller accounted for 27% and 16% of net accounts receivable as of June 30, 2015 and December 31, 2014 , respectively. There were no other resellers or end-user customers that accounted for 10% or more as a percentage of our revenue or net accounts receivable for any period presented.
Segments	Segments We have one reportable segment.
Revenue Recognition	Revenue Recognition We derive revenue principally from software-related arrangements consisting of perpetual software licenses, post-contract customer support for such licenses, or PCS or software support, including when and if available updates, and professional services such as consulting and training services. We also offer our software as term-based licenses and cloud-based arrangements. In addition, we install our software on servers that we ship to customers. We begin to recognize revenue when (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred or services have been provided, (iii) the sales price is fixed or determinable, and (iv) collection of the related receivable is probable. If collection is not considered probable, revenue is recognized only upon collection. Signed agreements, including by electronic acceptance, are used as evidence of an arrangement. Delivery is considered to occur when we provide a customer with a link and credentials to download our software. Delivery of a hardware appliance (an “appliance”) is considered to occur when title and risk of loss has transferred to the customer, which typically occurs when appliances are delivered to a common carrier. Delivery of services occurs when performed. Prior to January 1, 2013, we had not established vendor specific objective evidence, or VSOE, of fair value for any of the elements in our multiple-element arrangements. As of January 1, 2013, we determined that we had sufficient history to establish VSOE of fair value for PCS and professional services. Prior to January 1, 2013, we did not have VSOE of fair value for our software-related undelivered elements due to limited history of stand-alone sales transactions and inconsistency in pricing. We established VSOE of fair value when we had a substantial majority of stand-alone sales transactions of software support and services pricing within a narrow pricing band. In our VSOE analysis, we generally include stand-alone sales transactions completed during a rolling 12 month period unless a shorter period is appropriate due to changes in our pricing structure. We typically enter into multiple-element arrangements with our customers in which a customer may purchase a combination of software on a perpetual or subscription license, PCS, and professional services. The professional services are not considered essential to the functionality of the software. All of these elements are considered separate units of accounting. Our standard agreements do not include rights for customers to cancel or terminate arrangements or to return software to obtain refunds. We use the residual method to recognize revenue when a perpetual license arrangement includes one or more elements to be delivered at a future date provided the following criteria are met: (i) VSOE of fair value does not exist for one or more of the delivered items but exists for all undelivered elements, (ii) all other applicable revenue recognition criteria are met and (iii) the fair value of all of the undelivered elements is less than the arrangement fee. VSOE of fair value is based on the normal pricing practices for those products and services when sold separately by us and contractual customer renewal rates for post-contract customer support services. Under the residual method, the fair value of the undelivered elements is deferred and the remaining portion of the arrangement fee is recognized as revenue in the period in which it was earned. If evidence of the fair value of one or more undelivered elements does not exist, then the revenue is deferred and recognized when delivery of those elements occurs, or when fair value can be established, or ratably over the PCS period if the only undelivered element is PCS—we refer to these deferred revenue elements as the “Deferred Portion.” Revenue from subscriptions to our on-premise term licenses, arrangements where perpetual and subscriptions to our on-premise term licenses are sold together, and subscriptions to our cloud service are recognized ratably over the contractual term for all periods presented and are included as a component of subscription revenue within our consolidated statements of operations. We refer to arrangements where perpetual and subscriptions to our on-premise term licenses are sold together as “Bundled Arrangements.” Occasionally, we enter into multiple-element arrangements with our customers in which a customer may purchase a combination of software on a perpetual or term basis, PCS, professional services, and appliances. We generally provide the appliances and software upon the commencement of the arrangement and provide software-related elements throughout the support period. We account for appliance-bundled arrangements under the revised accounting standard related to multiple-element arrangements, Accounting Standard Update, or ASU, No. 2009-13, Multiple Element Arrangements , and determine the revenue to be recognized based on the standard’s fair value hierarchy and then determine the value of each element in the arrangement based on the relative selling price of the arrangement. Amounts related to appliances are generally recognized upon delivery with the remaining consideration allocated to software and software-related elements, which are recognized as described elsewhere in this policy. Revenue from PCS is recognized ratably over the support term and is included as a component of software support and service revenue within the consolidated statements of operations. Revenue related to professional services is recognized upon delivery and is included as a component of software support and services revenue within the consolidated statements of operations. Prior to establishing VSOE of fair value for PCS and professional services on January 1, 2013, we recognized revenue for multiple element software and software-related arrangements ratably from the date of service commencement over the contractual term of the related PCS arrangement. After January 1, 2013, the deferred revenue related to these arrangements continues to be recognized ratably over the remaining contractual term of the PCS arrangement. Approximately $616,000 and $1.4 million of perpetual license revenue in three months ended 2015 and 2014 , respectively, and approximately $1.4 and $3.0 million of perpetual license revenue in the six months ended June 30, 2015 and 2014 respectively, related to sales made prior to January 1, 2013. Approximately $758,000 and $2.1 million of deferred revenue as of June 30, 2015 and December 31, 2014 , respectively, related to sales made prior to January 1, 2013. We allocated the revenue from all multiple-element arrangements entered into prior to the establishment of VSOE of fair value for our PCS and professional services to each respective revenue caption using our best estimate of value of each element based on the facts and circumstances of the arrangements, our go-to-market strategy, price list and discounts from price list as applicable. We believe that the allocation between the revenue captions allows for greater transparency and comparability of revenue from period to period even though VSOE of fair value may not have existed at that time. Appliance revenue was less than 10% of total revenue for all periods presented and is included as a component of perpetual license revenue within the consolidated statements of operations. Generally, sales made through resellers are fulfilled to the end customer and processed in the same period. The inventory of licenses held by the resellers was immaterial for all periods presented. Shipping charges and sales tax billed to partners are excluded from revenue. Sales commissions and other incremental costs to acquire contracts are also expensed as incurred and are recorded in sales and marketing expense. For all arrangements, any revenue that has been deferred and is expected to be recognized beyond one year is classified as long-term deferred revenue in the consolidated balance sheets.
Cash Equivalents	Cash Equivalents We consider all highly liquid investments with an original maturity of three months or less to be cash equivalents. As of June 30, 2015 and December 31, 2014 cash and cash equivalents consist of cash deposited with banks, money market funds and investments that mature within three months of their purchase.
Held-To-Maturity Investments	Held-To-Maturity Investments We determine the appropriate classification of our fixed income investments at the time of purchase and reevaluate their classifications each reporting period. Investments are classified as held-to-maturity since the Company has positive intent and the ability to hold the securities to maturity. Held-to-maturity securities are stated at amortized cost.
Comprehensive Loss	Comprehensive Loss Comprehensive loss includes all changes in equity (net assets) during a period from non-owner sources. For the three and six months ended June 30, 2015 and 2014 , there were no differences between net loss and comprehensive loss. Therefore, the consolidated statements of comprehensive loss have been omitted.
Net Loss per Share of Common Stock	Net Loss per Share of Common Stock Basic net loss per common share is calculated by dividing the net loss by the weighted-average number of common shares outstanding during the period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common shares and potentially dilutive securities outstanding for the period determined using the treasury-stock and if-converted methods. For purposes of the diluted net loss per share calculation, unvested restricted stock and stock options are considered to be potentially dilutive securities. Because we have reported a net loss for the three and six months ended June 30, 2015 and 2014 , the number of shares used to calculate diluted net loss per common share is the same as the number of shares used to calculate basic net loss per common share for those periods presented because the potentially dilutive shares would have been anti-dilutive if included in the calculation.
Inventory	Inventory We have appliances (industry standard hardware servers available from multiple vendors) that are available for customers to purchase, on which we will preinstall our software prior to shipment. Inventory is stated at the lower of cost or net realizable value. We value our inventory using the first-in, first-out method. Appropriate consideration is given to obsolescence, excessive levels, deterioration and other factors in evaluating net realizable value—such adjustments were not material for any period presented. The entire inventory is comprised of finished goods. As of June 30, 2015 and December 31, 2014 , we had inventory of $313,000 and $528,000 , respectively, which is included in prepaid expenses and other current assets in the consolidated balance sheets.
Software Development Costs	Software Development Costs Incurred in Connection with Software to be Sold or Marketed The costs to develop new software products and enhancements to existing software products are expensed as incurred until technological feasibility has been established. We consider technological feasibility to have occurred when all planning, designing, coding and testing have been completed according to design specifications. Once technological feasibility is established, any additional costs would be capitalized. We believe our current process for developing software is essentially completed concurrent with the establishment of technological feasibility, and accordingly, no costs have been capitalized.
Internal Use Software	Internal Use Software We capitalize costs incurred during the application development stage related to our internally used software. Such costs are primarily incurred by third party vendors and consultants. Costs related to preliminary project activities and post-implementation activities are expensed as incurred. Amounts capitalized in all periods presented were not significant. All software development costs incurred in connection with our cloud offering, or SaaS are also sold or marketed to partners or end customers, therefore we start capitalizing costs when technological feasibility is achieved. No costs were capitalized in any periods presented as we believe that our current process for developing software is essentially completed concurrent with the establishment of technological feasibility.
Property and Equipment	Property and Equipment Property and equipment are stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives, determined to be three years for computers and equipment and software, five years for furniture and fixtures, and the lesser of the remaining lease term or estimated useful life for leasehold improvements. Expenditures for repairs and software support are charged to expense as incurred. Upon disposition, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is reflected as operating expenses in the consolidated statements of operations.
Goodwill and Intangible Assets	Goodwill and Intangible Assets We record the excess of the acquisition purchase price over the fair value of the tangible and identifiable intangible assets acquired as goodwill. We perform an impairment test of our goodwill in the third quarter of our fiscal year, or more frequently if indicators of potential impairment arise. We have a single reporting unit and consequently evaluate goodwill for impairment based on an evaluation of the fair value of the Company as a whole. We record purchased intangible assets at their respective estimated fair values at the date of acquisition. Purchased intangible assets are being amortized using the straight-line method over their remaining estimated useful lives, which range from three to five years. We evaluate the remaining useful lives of intangible assets on a periodic basis to determine whether events or circumstances warrant a revision to the remaining estimated amortization period.
Long-Lived Assets with Finite Lives	Long-Lived Assets with Finite Lives Long-lived assets are reviewed for possible impairment whenever events or circumstances indicate that the carrying amount of these assets may not be recoverable. We evaluate the recoverability of each of our long-lived assets, including purchased intangible assets and property and equipment, by comparison of its carrying amount to the future undiscounted cash flows we expect the asset to generate. If we consider the asset to be impaired, we measure the amount of any impairment as the difference between the carrying amount and the fair value of the impaired asset.
Stock-Based Compensation	Stock-Based Compensation We use the estimated grant-date fair value method of accounting in accordance with Accounting Standards Codification, or ASC, Topic 718 Compensation—Stock Compensation . Fair value is determined using the Black-Scholes Model using various inputs, including our estimates of expected volatility, term and future dividends. We estimated the forfeiture rate for the three and six months ended June 30, 2015 and the corresponding periods of 2014 based on our historical experience for annual grant years where the majority of the vesting terms have been satisfied. We recognize compensation costs for awards with service and performance vesting conditions on an accelerated method over the requisite service period of the award. For stock options, restricted stock units or restricted stock grants with no performance condition, we recognize compensation costs on a straight-line basis over the requisite service period of the award, which is generally the vesting term of four years .
Research and Development	Research and Development Research and development, or R&D, costs are charged to expense as incurred.
Advertising	Advertising Advertising costs are expensed and included in sales and marketing expense when incurred. Advertising expense for the three and six months ended June 30, 2015 and 2014 was not significant.
Income Taxes	Income Taxes We account for income taxes in accordance with ASC Topic 740, Income Taxes , under which deferred tax liabilities and assets are recognized for the expected future tax consequences of temporary differences between financial statement carrying amounts and the tax basis of assets and liabilities and net operating loss and tax credit carryforwards. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. We use a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. A tax position is recognized when it is more likely than not that the tax position will be sustained upon examination, including resolution of any related appeals or litigation processes. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority. The standard also provides guidance on derecognition of tax benefits, classification on the balance sheet, interest and penalties, accounting in interim periods, disclosure and transition.
Recent Accounting Pronouncements	Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board, or FASB, or other standard setting bodies and adopted by us as of the specified effective date. Unless otherwise discussed, the impact of recently issued standards that are not yet effective will not have a material impact on our financial position or results of operations upon adoption. In May 2014, the FASB, jointly with the International Accounting Standards Board, issued a comprehensive new standard on revenue recognition from contracts with customers. The standard’s core principle is that a reporting entity will 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. In applying this new guidance to contracts within its scope, an entity will: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation. Additionally, this new guidance will require significantly expanded disclosures about revenue recognition. As clarified by the FASB on July 9, 2015, provisions of this new standard are effective for annual reporting periods (including interim reporting periods within those annual periods) beginning after December 15, 2017. Early adoption is permitted for annual reporting periods (including interim reporting periods within those annual periods) beginning after December 15, 2016. Entities have the option of using either a full retrospective or a modified retrospective approach to adopt this new guidance. We are currently evaluating the potential effect on our consolidated financial statements from adoption of this standard.
