General and Basis of Presentation [Abstract]
Segment Reporting	Segment Reporting Operating segments are defined as components of an enterprise for which separate financial information is available and evaluated regularly by the chief operating decision maker ("CODM"), or decision making group, in deciding how to allocate resources and assess performance. We currently operate in one operating and reportable business segment for financial reporting purposes. We currently have the following three business lines: Cyber Operations and Defense, Identity Management, and IT & Enterprise Solutions. Our Chief Executive Officer is the CODM. Our CODM manages our business primarily by function and reviews financial information on a consolidated basis, accompanied by disaggregated information by line of business as well as certain operational data, for purposes of allocating resources and evaluating financial performance. The CODM only evaluates profitability based on consolidated results.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers," which requires an entity to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. In July 2015, the FASB finalized the delay of the effective date by one year, making the new standard effective for interim periods and annual periods beginning after December 15, 2017. The new standard can be applied retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of the change recognized at the date of the initial application. We are currently assessing the impact the adoption of ASU 2014-09 will have on our condensed consolidated financial position, results of operations and cash flows. In August 2014, the FASB issued ASU No. 2014-15, "Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern." The new standard addresses management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. Management's evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued. The new standard will be effective for the first interim period within annual reporting periods beginning after December 15, 2016. Early adoption is permitted. The adoption of this update will not have a material impact on our condensed consolidated financial position, results of operations and cash flows. In July 2015, the FASB issued ASU 2015-11, "Simplifying the Measurement of Inventory," which requires an entity to measure inventory at the lower of cost and net realizable value. The provisions of the ASU are effective for periods beginning after December 15, 2016. We are currently assessing the impact the adoption of this ASU will have on our condensed consolidated financial position, results of operations and cash flows. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." The guidance in this update supersedes the requirements in Accounting Standards Codification ("ASC") Topic 840, Leases. The update will require business entities to recognize lease assets and liabilities on the balance sheet and to disclose key information about leasing arrangements. A lessee would recognize a liability to make lease payments and a right-of-use asset representing its right to use the leased asset for the lease term. For public companies, this update will be effective for interim and annual periods beginning after December 15, 2018, and is to be applied on a modified retrospective basis. We are currently assessing the impact the adoption of this ASU will have on our condensed consolidated financial position, results of operations and cash flows. In March 2016, the FASB issued ASU 2016-09, "Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting," which involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The new standard will be effective for interim and annual reporting periods beginning after December 15, 2016, with early adoption permitted. The adoption of this update will not have a material impact on our condensed consolidated financial position, results of operations and cash flows. In June 2016, the FASB issued ASU 2016-13, "Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments," which introduces new guidance for estimating credit losses on certain types of financial instruments based on expected losses and the timing of the recognition of such losses. The new standard will be effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. We are currently assessing the impact the adoption of this ASU will have on our condensed consolidated financial position, results of operations and cash flows.
Revenue Recognition	Revenue Recognition Revenues are recognized in accordance with FASB ASC 605-10-S99. We consider amounts earned upon evidence that an arrangement has been obtained, services are delivered, fees are fixed or determinable, and collectability is reasonably assured. Additionally, revenues on arrangements requiring the delivery of more than one product or service are recognized in accordance with ASC 605-25, "Revenue Arrangements with Multiple Deliverables," which addresses and requires the separation and allocation at the inception of the arrangement of all deliverables based on their relative selling prices. This determination is made first by employing vendor-specific objective evidence ("VSOE"), to the extent it exists, then third-party evidence ("TPE") of selling price, to the extent that it exists. Given the nature of the deliverables contained in our multi-element arrangements, which often involve the design and/or delivery of complex or technical solutions to the government, we have not obtained TPE of selling prices on multi-element arrangements due to the significant differentiation which makes obtaining comparable pricing of products with similar functionality impractical. Therefore we do not utilize TPE. If VSOE and TPE are not determinable, we use our best estimate of selling price ("ESP") as defined in ASC 605-25, which represents our best estimate of the prices under the terms and conditions of a particular order for the various elements if they were sold on a stand-alone basis. We recognize revenues for software arrangements upon persuasive evidence of an arrangement, delivery of the software, and determination that collection of a fixed or determinable license fee is probable. Revenues for software licenses sold on a subscription basis are recognized ratably over the related license period. For arrangements where the sale of software licenses are bundled with other products, including software products, upgrades and enhancements, post-contract customer support ("PCS"), and installation, the relative fair value of each element is determined based on VSOE. VSOE is defined by ASC 985-605, "Software Revenue Recognition," and is limited to the price charged when the element is sold separately or, if the element is not yet sold separately, the price set by management having the relevant authority. When VSOE exists for undelivered elements, the remaining consideration is allocated to delivered elements using the residual method. If VSOE does not exist for the allocation of revenue to the various elements of the arrangement, all revenue from the arrangement is deferred until the earlier of the point at which (1) such VSOE does exist or (2) all elements of the arrangement are delivered. PCS revenues, upon being unbundled from a software license fee, are recognized ratably over the PCS period. Software arrangements requiring significant production, modification, or customization of the software are accounted for in accordance with ASC 605-35 "Construction-Type and Production-Type Contracts". We may use subcontractors and suppliers in the course of performing contracts and under certain contracts we provide supplier procurement services and materials for our customers. Some of these arrangements may fall within the scope of ASC 605-45, "Reporting Revenue Gross as a Principal versus Net as an Agent." We presume that revenues on our contracts are recognized on a gross basis, as we generally provide significant value-added services, assume credit risk, and reserve the right to select subcontractors and suppliers, but we evaluate the various criteria specified in the guidance in making the determination of whether revenue should be recognized on a gross or net basis. A description of the business lines, the typical deliverables, and the revenue recognition criteria in general for such deliverables follows: Cyber Operations and Defense – Our Cyber Operations and Defense business line consists of Cyber Security and Secure Mobility solutions areas. Regarding our deliverables of Cyber Security (formerly Information Assurance) solutions, we provide Xacta IA Manager software and cybersecurity services to our customers. The software and accompanying services fall within the scope of ASC 985-605, "Software Revenue Recognition," as discussed above. We provide consulting services to our customers under either a FFP or T&M basis. Such contracts fall under the scope of ASC 605-10-S99. Revenue for FFP services is recognized on a proportional performance basis. FFP services may be billed to the customer on a percentage-of-completion basis or based upon milestones as appropriate under a particular contract, which may approximate the proportional performance of the services under the agreements, as specified in such agreements. To the extent that customer billings exceed the performance of the specified services, the revenue would be deferred. Revenue is recognized under T&M contracts based upon specified billing rates and other direct costs as incurred. For cost plus fixed fee ("CPFF") contracts, revenue is recognized in proportion to the allowable costs incurred unless indicated otherwise in the terms of the contract. Regarding our deliverables of Secure Mobility (formerly Secure Networks) solutions, we provide wireless and wired networking solutions consisting of hardware and services to our customers. Also, within this area is our Emerging Technologies Group creating innovative, custom-tailored solutions for government and commercial enterprises. The solutions within the Secure Mobility and Emerging Technologies groups are generally sold as firm-fixed price ("FFP") bundled solutions. Certain of these networking solutions involve contracts to design, develop, or modify complex electronic equipment configurations to a buyer's specification or to provide network engineering services, and as such fall within the scope of ASC 605-35. Revenue is earned upon percentage of completion based upon proportional performance, such performance generally being defined by performance milestones. Certain other solutions fall within the scope of ASC 605-10-S99, such as resold information technology products, like laptops, printers, networking equipment and peripherals, and ASC 605-25, such as delivery orders for multiple solutions deliverables. For product sales, revenue is recognized upon proof of acceptance by the customer, otherwise it is deferred until such time as the proof of acceptance is obtained. For example, in delivery orders for Department of Defense customers, which comprise the majority of the Company's customers, such acceptance is achieved with a signed Department of Defense Form DD-250 or electronic invoicing system equivalent. Services provided under these contracts are generally provided on a FFP basis, and as such fall within the scope of ASC 605-10-S99. Revenue for services is recognized based on proportional performance, as the work progresses. FFP services may be billed to the customer on a percentage-of-completion basis or based upon milestones, which may approximate the proportional performance of the services under the agreements, as specified in such agreements. To the extent that customer billings exceed the performance of the specified services, the revenue would be deferred. Revenue is recognized under time-and-materials ("T&M") services contracts based upon specified billing rates and other direct costs as incurred. Identity Management (formerly Telos ID) – We provide our identity assurance and access management solutions and services and sell information technology products, such as computer laptops and specialized printers, and consumables, such as identity cards, to our customers. The solutions are generally sold as FFP bundled solutions, which would typically fall within the scope of ASC 605-25 and ASC 605-10-S99. Revenue for services is recognized based on proportional performance, as the work progresses. FFP services may be billed to the customer on a percentage-of-completion basis or based upon milestones, which may approximate the proportional performance of the services under the agreements, as specified in such agreements. To the extent that customer billings exceed the performance of the specified services, the revenue would be deferred. Revenue is recognized under T&M contracts based upon specified billing rates and other direct costs as incurred. IT & Enterprise Solutions (formerly Secure Communications) – We provide Secure Information eXchange (T-6) suite of products which include the flagship product the Automated Message Handling System ("AMHS"), Secure Collaboration, Secure Discovery, Secure Directory and Cross Domain Communication, as well as related services to our customers. The system and accompanying services fall within the scope of ASC 985-605, as fully discussed above. Other services fall within the scope of ASC 605-10-S99 for arrangements that include only T&M contracts and ASC 605-25 for contracts with multiple deliverables such as T&M elements and FFP services. Under such arrangements, the T&M elements are established by direct costs. Revenue is recognized on T&M contracts according to specified rates as direct labor and other direct costs are incurred. For cost plus fixed fee ("CPFF") contracts, revenue is recognized in proportion to the allowable costs incurred unless indicated otherwise in the terms of the contract. Revenue for FFP services is recognized on a proportional performance basis. FFP services may be billed to the customer on a percentage-of-completion basis or based upon milestones, which may approximate the proportional performance of the services under the agreements, as specified in such agreements. To the extent that customer billings exceed the performance of the specified services, the revenue would be deferred. Estimating future costs and, therefore, revenues and profits, is a process requiring a high degree of management judgment. In the event of a change in total estimated contract cost or profit, the cumulative effect of a change is recorded in the period the change in estimate occurs. To the extent contracts are incomplete at the end of an accounting period, revenue is recognized on the percentage-of-completion method, on a proportional performance basis, using costs incurred in relation to total estimated costs, or costs are deferred as appropriate under the terms of a particular contract. In the event cost estimates indicate a loss on a contract, the total amount of such loss, excluding overhead and general and administrative expense, is recorded in the period in which the loss is first estimated.
Accounts Receivable	Accounts Receivable Accounts receivable are stated at the invoiced amount, less allowances for doubtful accounts. Collectability of accounts receivable is regularly reviewed based upon management's knowledge of the specific circumstances related to overdue balances. The allowance for doubtful accounts is adjusted based on such evaluation. Accounts receivable balances are written off against the allowance when management deems the balances uncollectible.
Inventories	Inventories Inventories are stated at the lower of cost or net realizable value, where cost is determined on the weighted average method. Substantially all inventories consist of purchased commercial off-the-shelf hardware and software, and component computer parts used in connection with system integration services that we perform. An allowance for obsolete, slow-moving or nonsalable inventory is provided for all other inventory. This allowance is based on our overall obsolescence experience and our assessment of future inventory requirements. This charge is taken primarily due to the age of the specific inventory and the significant additional costs that would be necessary to upgrade to current standards as well as the lack of forecasted sales for such inventory in the near future. Gross inventory is $9.4 million and $4.4 million as of June 30, 2016 and December 31, 2015, respectively. As of June 30, 2016, it is management's judgment that we have fully provided for any potential inventory obsolescence, which was $1.5 million as of June 30, 2016 and December 31, 2015.
Income Taxes	Income Taxes We account for income taxes in accordance with ASC 740-10, "Income Taxes." Under ASC 740-10, deferred tax assets and liabilities are recognized for the estimated future tax consequences of temporary differences and income tax credits. Deferred tax assets and liabilities are measured by applying enacted statutory tax rates that are applicable to the future years in which deferred tax assets or liabilities are expected to be settled or realized for differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. Any change in tax rates on deferred tax assets and liabilities is recognized in net income in the period in which the tax rate change is enacted. We record a valuation allowance that reduces deferred tax assets when it is "more likely than not" that deferred tax assets will not be realized. We are required to establish a valuation allowance for deferred tax assets if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Based on available evidence, realization of deferred tax assets is dependent upon the generation of future taxable income. We considered projected future taxable income, tax planning strategies, and reversal of taxable temporary differences in making this assessment. As such, we have determined that a full valuation allowance is required as of June 30, 2016 and December 31, 2015. We are not able to use temporary taxable differences related to goodwill, as a source of future taxable income. As a result of a full valuation allowance against our deferred tax assets, a deferred tax liability (hanging credit) related to goodwill remains on our condensed consolidated balance sheet at June 30, 2016 and December 31, 2015. We follow the provisions of ASC 740-10 related to accounting for uncertainty in income taxes. The accounting estimates related to liabilities for uncertain tax positions require us to make judgments regarding the sustainability of each uncertain tax position based on its technical merits. If we determine it is more likely than not that a tax position will be sustained based on its technical merits, we record the impact of the position in our consolidated financial statements at the largest amount that is greater than fifty percent likely of being realized upon ultimate settlement. These estimates are updated at each reporting date based on the facts, circumstances and information available. We are also required to assess at each reporting date whether it is reasonably possible that any significant increases or decreases to our unrecognized tax benefits will occur during the next 12 months. The provision for income taxes in interim periods is computed by applying the estimated annual effective tax rate against earnings before income tax expense for the period. In addition, non-recurring or discrete items are recorded during the period in which they occur.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets We evaluate the impairment of goodwill and other intangible assets in accordance with ASC 350, "Intangibles - Goodwill and Other," which requires goodwill and indefinite-lived intangible assets to be assessed on at least an annual basis for impairment using a fair value basis. Between annual evaluations, if events occur or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying amount, then impairment must be evaluated. Such circumstances could include, but are not limited to: (1) a significant adverse change in legal factors or business climate, or (2) a loss of key contracts or customers. As the result of an acquisition, we record any excess purchase price over the net tangible and identifiable intangible assets acquired as goodwill. An allocation of the purchase price to tangible and intangible net assets acquired is based upon our valuation of the acquired assets. Goodwill is not amortized, but is subject to annual impairment tests. We complete our goodwill impairment tests as of December 31st each year. Additionally, we make evaluations between annual tests if events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The evaluation is based on the estimation of the fair values of our three reporting units, Cyber Operations and Defense ("CO&D"), Identity Management, and IT & Enterprise Solutions, of which goodwill is housed in the CO&D reporting unit, in comparison to the reporting unit's net asset carrying values. Our discounted cash flows required management judgment with respect to forecasted revenue streams and operating margins, capital expenditures and the selection and use of an appropriate discount rate. We utilized the weighted average cost of capital as derived by certain assumptions specific to our facts and circumstances as the discount rate. The net assets attributable to the reporting units are determined based upon the estimated assets and liabilities attributable to the reporting units in deriving its free cash flows. In addition, the estimate of the total fair value of our reporting units is compared to the market capitalization of the Company. The Company's assessment resulted in a fair value that was greater than the Company's carrying value, therefore the second step of the impairment test, as prescribed by the authoritative literature, was not required to be performed and no impairment of goodwill was recorded as of December 31, 2015. There were no triggering events which would require goodwill impairment consideration during the quarter. Subsequent reviews may result in future periodic impairments that could have a material adverse effect on the results of operations in the period recognized. Recent operating results have reduced the projection of future cash flow growth potential, which indicates that certain negative potential events, such as a material loss or losses on contracts, or failure to achieve projected growth could result in impairment in the future. We estimate fair value of our reporting unit and compare the valuation with the respective carrying value for the reporting unit to determine whether any goodwill impairment exists. If we determine through the impairment review process that goodwill is impaired, we will record an impairment charge in our consolidated statements of operations. Goodwill is amortized and deducted over a 15-year period for tax purposes. Other intangible assets consist primarily of customer relationship enhancements. Other intangible assets are amortized on a straight-line basis over their estimated useful lives of 5 years. The amortization is based on a forecast of approximately equal annual customer orders over the 5-year period. Other intangible assets are subject to impairment review if there are events or changes in circumstances that indicate that the carrying amount is not recoverable.
Stock-Based Compensation	Stock-Based Compensation Compensation cost is recognized based on the requirements of ASC 718, "Stock Compensation," for all share-based awards granted. Since June 2008, we have issued restricted stock (Class A common) to our executive officers, directors and employees. To date, there have been no grants issued in 2016. As of June 30, 2016, there were 19,047,259 shares of restricted stock outstanding. Such stock is subject to a vesting schedule as follows: 25% of the restricted stock vests immediately on the date of grant, thereafter, an additional 25% will vest annually on the anniversary of the date of grant subject to continued employment or services. In the event of death of the employee or a change in control, as defined by the Telos Corporation 2008 Omnibus Long-Term Incentive Plan or the 2013 Omnibus Long-Term Incentive Plan, all unvested shares shall automatically vest in full. The value of our common stock is deemed to be immaterial, based on the deduction of our outstanding debt, capital lease obligations, and preferred stock from an estimated enterprise value, which was estimated based on discounted cash flow analysis, comparable public company analysis, and comparable transaction analysis. Additionally, we determined that a significant change in the valuation estimate for common stock would not have a significant effect on the condensed consolidated financial statements.
Other Comprehensive Income	Other Comprehensive Income Our functional currency is the U.S. Dollar. For one of our wholly owned subsidiaries, the functional currency is the local currency. For this subsidiary, the translation of its foreign currency into U.S. Dollars is performed for assets and liabilities using current foreign currency exchange rates in effect at the balance sheet date and for revenue and expense accounts using average foreign currency exchange rates during the period. Translation gains and losses are included in stockholders' deficit as a component of accumulated other comprehensive income.
