Summary of Significant Accounting Policies
 
Principles of Consolidation
 
Our consolidated financial statements include our accounts and those of our wholly owned subsidiaries. Intercompany balances and transactions have been eliminated in consolidation.
 
Cash and Cash Equivalents
 
Cash and all highly liquid investments purchased with an original maturity of less than
three
months are considered to be cash and cash equivalents.
 
Risk Concentration
 
Financial instruments, which potentially subject us to concentrations of credit risk, are primarily cash and cash equivalents, investments and accounts receivable. Cash and cash equivalent deposits are at risk to the extent that they exceed Federal Deposit Insurance Corporation insured amounts. To minimize risk, we place our investments in U.S. government obligations, corporate securities and money market funds. Substantially all of our cash, cash equivalents and investments are maintained with
two
major U.S. financial institutions. We do not believe that we are subject to any unusual financial risk with our banking arrangements. We have not experienced any significant losses on our cash and cash equivalents.
 
We sell our products to customers in diversified industries worldwide and periodically have receivables from customers, primarily in North America, Europe and Asia. Fluctuations in currency exchange rates and adverse economic developments in foreign countries could adversely affect the Company’s operating results. We perform ongoing credit evaluations of our customers’ financial condition and generally require no collateral. We maintain reserves for potential credit losses, and such losses, in the aggregate, have historically been minimal.
 
Accounts Receivable and Allowance for Doubtful Accounts
 
Trade accounts receivable are stated at the amount we expect to collect. We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. Management considers the following factors when determining the collectability of specific customer accounts: customer credit-worthiness, past transaction history with the customer, current economic industry trends, and changes in customer payment terms. If the financial condition of our customers were to deteriorate, adversely affecting their ability to make payments, additional allowances would be required. Based on management’s assessment, we provide for estimated uncollectible amounts through a charge to earnings and an increase to a valuation allowance. Balances that remain outstanding after we have used reasonable collection efforts are written off through a charge to the valuation allowance. There was
no
allowance at
December
 
31,
2016
and
2015
.
 
Inventories
 
Inventories are stated at the lower of cost or market. We value our inventories using average cost, which approximates actual cost on a
first
-in,
first
-out basis. Our management estimates the allowance required to state inventory at the lower of cost or market. There is a risk that we will forecast demand for our products and market conditions incorrectly and maintain excess inventories. Therefore, there can be no assurance that we will not maintain excess inventory and incur inventory lower of cost or market charges in the future. All inventory on hand at
December
 
31,
2016
and
2015
is finished goods inventory.
 
Property and Equipment
 
Equipment and furniture and fixtures are stated at cost less accumulated depreciation and depreciated on a straight-line basis over the estimated useful lives of the assets. Such lives vary from
1
to
5
years. Leasehold improvements are stated at cost less accumulated amortization and are amortized on a straight-line basis over the shorter of estimated useful lives of the assets or the remaining terms of the leases. Such lives vary from
2
to
5
years. Expenditures for major renewals and betterments that extend the useful lives of property and equipment are capitalized. Repair and maintenance costs are expensed as incurred. Depreciation and amortization expense totaled approximately
$291,000
and
$299,000
for the years ended
December
 
31,
2016
and
2015,
respectively.
 
Long-Lived Assets
 
We review long-lived assets, including property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset
may
not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted cash flows to be generated by the asset. If the carrying value exceeds the future undiscounted cash flows, the assets are written down to fair value. During the years ended
December
 
31,
2016
and
2015,
there was no impairment of long-lived assets.
 
Foreign Currency
 
All assets and liabilities in the balance sheets of foreign subsidiaries whose functional currency is other than the U.S. dollar are translated at year-end exchange rates. All revenues and expenses in the statement of operations of these foreign subsidiaries are translated at average exchange rates for the year. Translation gains and losses are not included in determining net income but are shown in accumulated other comprehensive loss in the stockholders’ deficit section of the consolidated balance sheet. Foreign currency transaction gains and losses are included in determining net loss and were not significant.
 
Accounting for Stock Options
 
We account for stock options using the guidance in Financial Accounting Standards Board Accounting Standards Codification (“FASB ASC”) Topic
718.
FASB ASC Topic
718
requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values.
 
Stock-based compensation expense recognized in the statements of operations for the years ended
2016
and
2015
is based on awards ultimately expected to vest, reduced by estimated forfeitures. FASB ASC Topic
718
requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
 
Valuation Assumptions
 
The fair values of option awards were estimated at the date of grant using a Black-Scholes option-pricing model with the following assumptions for fiscal years ended
December
 
31,
2016
and
2015,
respectively:
 
 
 
201
6
 
 
2015
 
                 
Weighted average grant date fair value
  $
0.28
    $
1.94
 
Weighted average assumptions used:
               
Expected dividend yield
   
0.00
%

Risk-free interest rate

Expected volatility
   
110.24
%
   
229.24
%
Expected life (in years)
   
5.00
     
5.00
 
 
Expected volatility is based on historical volatility and in part on implied volatility. The expected term considers the contractual term of the option as well as historical exercise and forfeiture behavior. The risk-free interest rate is based on the rates in effect on the grant date for U.S. Treasury instruments with maturities matching the relevant expected term of the award.
 
Net Loss Per Share
 
We report
two
separate net loss per share numbers, basic and diluted. Basic net loss attributable to common stockholders per share is computed by dividing net loss attributable to common stockholders for the year by the weighted average number of common shares outstanding for the year. Diluted net loss attributable to common stockholders per share is computed by dividing the net loss attributable to common stockholders for the year by the weighted average number of common shares and dilutive common stock equivalents outstanding for the year. Our common stock equivalents include all common stock issuable upon conversion of convertible preferred stock and the exercise of outstanding options. Common stock equivalents are included in the diluted loss per share for the years ended
December
 
31,
2016
and
2015
except in cases where the issuance would be anti-dilutive. The aggregate number of common stock equivalents excluded from the diluted loss per share calculation at
December
 
31,
2016
and
2015
totaled
3,509,241
and
3,765,959,
respectively.
 
Revenue Recognition
 
We generally recognize product revenue upon shipment. These products include both hardware and perpetual software licenses, as we do not currently offer software on a subscription basis. We accrue for estimated warranty costs and sales returns at the time of shipment based on our experience. There is a risk that technical issues on new products could result in unexpected warranty costs and returns. To the extent that our warranty costs exceed our expectations, we will increase our warranty reserve to compensate for the additional expense expected to be incurred. We review these estimates periodically and determine the appropriate reserve percentage. However, to date, warranty costs and sales returns have not been material. The customer
may
return a product only under very limited circumstances during the
first
thirty
days from delivery for a replacement if the product is damaged or for a full refund if the product does not perform as intended. Historically, most or our sales returns were related to hardware-based products. As we continue to migrate away from such hardware-based products, these returns have declined.
 
We recognize software revenue from the licensing of our software products in accordance with FASB ASC Topic
605
whereby revenue from the licensing of our products is not recognized until all
four
of the following have been met: i) execution of a written agreement; ii) delivery of the product has occurred; iii) the fee is fixed and determinable; and iv) collectability is probable. Bundled hardware and software product revenue is recognized at time of delivery, as our licenses are not sold on a subscription basis. Data updates are typically done monthly and revenue will be matched accordingly. Product sales
may
include maintenance and customer support allocated revenue in an arrangement using estimated selling prices of the delivered goods and services based on a selling price hierarchy using the relative selling price method. All of our product offering and service offering market values are readily determined based on current and prior stand-alone sales. We
may
defer and recognize maintenance, updates and support revenue over the term of the contract period, which is generally
one
year. Deferred revenue represents deposits on licensing for software products.
 
Service revenue, primarily including maintenance, training and installation are recognized upon delivery of the service and typically are unrelated to product sales. To date, training and installation revenue has not been material. These revenues are included in net customer support and maintenance revenues in the statement of operations.
 
Our normal payment terms offered to customers, distributors and resellers are net
30
days domestically and net
45
days internationally. We do not offer payment terms that extend beyond
one
year and rarely do we extend payment terms beyond our normal terms. If certain customers do not meet our credit standards, we do require payment in advance to limit our credit exposure.
 
Shipping and handling costs are billed to the customer and included in product revenue. Our costs of shipping and handling are included in cost of product revenue.
 
Research and Development Costs
 
We incur research and development costs that relate primarily to the development of new security software, appliances and integrated solutions, and major enhancements to existing services and products. Research and development costs are comprised primarily of salaries and related benefits expenses, contract labor and prototype and other related expenses.
 
Software development costs are included in research and development and are expensed as incurred. FASB ASC Topic
350
Intangibles—Goodwill and Other
requires that software development costs incurred subsequent to reaching technological feasibility be capitalized, if material. If the process of developing a new product or major enhancement does not include a detailed program design, technological feasibility is determined only after completion of a working model. To date, the period between achieving technological feasibility and the general availability of such software has been short, and the software development costs qualifying for capitalization have been insignificant.
 
Use of Estimates
 
The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Estimates are used for, but not limited to, the accounting for doubtful accounts, sales discounts, sales returns, revenue recognition, warranty costs, inventory obsolescence, depreciation and income taxes. Actual results could differ from these estimates.
 
Fair Value of Financial Instruments
 
We calculate the fair value of our assets and liabilities which qualify as financial instruments and include additional information in the notes to consolidated financial statements when the fair value is different than the carrying value of these financial instruments. The estimated fair value of accounts receivable, accounts payable and accrued expenses, and dividends payable approximate their carrying amounts due to the relatively short maturity of these instruments. Loans payable to officer are with a related party and as a result do not bear market rates of interest.  Capital leases approximate fair value as they bear market rates of interest. Management believes based on its current financial position that it could not obtain comparable amounts of
third
party financing, and as such cannot estimate the fair value of the loans payable to officer. None of these instruments are held for trading purposes.
 
Income Taxes
 
Deferred income taxes are determined using the liability method in accordance with FASB ASC
740,
Accounting for Income Taxes
. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. In addition, a valuation allowance is established to reduce any deferred tax asset for which it is determined that it is more likely than not that some portion of the deferred tax asset will not be realized.
 
FASB ASC
740
creates a single model to address accounting for uncertainty in tax positions by prescribing a minimum recognition threshold that a tax position is required to meet before being recognized in the financial statements. FASB ASC
740
also provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. There are no unrecognized tax benefits to disclose in the notes to the consolidated financial statements.
 
We file income tax returns in the United States federal jurisdiction. At
December
 
31,
2016,
tax returns related to fiscal years ended
December
 
31,
2013
through
December
 
31,
2015
remain open to possible examination by the tax authorities. No tax returns are currently under examination by any tax authorities. We did
not
incur any penalties or interest during the years ended
December
 
31,
2016
and
2015
.
 
Recent Accounting Pronouncements
 
Revenue Recognition
 
In
May
 
2014,
the FASB issued Accounting Standards Update No. 
2014
-
09,
Revenue from Contracts with Customers (ASU
2014
-
09),
which supersedes most current revenue recognition guidance under U.S. GAAP. The core principle of ASU
2014
-
09
is 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. ASU
2014
-
09
defines a
five
step process to achieve this core principle and, in doing so, more judgment and estimates
may
be required within the revenue recognition process than are required under existing U.S. GAAP. The standard is effective for us beginning
2018,
and requires using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU
2014
-
09
recognized at the date of adoption (which includes additional footnote disclosures). We are currently evaluating the impact of our pending adoption of ASU
2014
-
09
on our consolidated financial statements and have not yet determined the method by which we will adopt the standard in
2018.
We do not believe the adoption of this guidance will have a material impact on our financial statements.
 
In
November
 
2015,
the Financial Accounting Standards Board (“FASB”) issued ASU
2015
-
17,
 Income Taxes (Topic
740):
Balance Sheet Classification of Deferred Taxes, which eliminates the current requirement to present deferred tax liabilities and assets as current and noncurrent in a classified balance sheet. Instead, all deferred tax assets and liabilities will be required to be classified as noncurrent. The new standard will be effective for us beginning with the
first
quarter of
2017.
Early adoption is permitted. We do not believe the adoption of this new standard will have a material impact on our Consolidated Financial Statements.
 
In
February
2016,
the FASB issued Accounting Standards Update No.
2016
-
02,
Leases (Topic
842)
(ASU
2016
-
02),
which generally requires companies to recognize operating and financing lease liabilities and corresponding right-of-use assets on the balance sheet. This guidance will be effective for us in the
first
quarter of
2019
on a modified retrospective basis and early adoption is permitted. We do not believe the adoption of this guidance will have a material impact on our consolidated financial statements and related disclosures.
 
In
March
2016,
the FASB issued new guidance simplifying the accounting for stock-based compensation transactions, including income tax consequences, classification of awards as equity or liabilities, forfeitures, and classification on the statement of cash flows (“ASU
2016
-
09”).
This update is effective for annual reporting periods beginning after
December
15,
2016,
and early adoption is permitted. We do not believe the adoption of this guidance will have a material impact on our results of operations, financial position, and disclosures.
 
In
August
2014,
the FASB issued authoritative guidance that requires an entity’s management to evaluate, for each reporting period, whether there are conditions and events that raise substantial doubt about the entity’s ability to continue as a going concern within
one
year after the financial statements are issued. Additional disclosures are required if management concludes that conditions or events raise substantial doubt about the entity’s ability to continue asa going concern. This guidance is effective for annual reporting periods ending after
December
15,
2016,
and for annual periods and interim periods thereafter, with earlier adoption permitted. The adoption of this guidance did not have an impact on the consolidated financial position, results of operations
or cash flows and we have updated our disclosures as necessary based on this guidance.
