Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation of the Company’s unaudited condensed consolidated financial statements have been included. The results of operations for the three months ended March 31, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021 or any future period. The unaudited condensed consolidated balance sheet as of December 31, 2020 has been derived from audited consolidated financial statements at that date, but does not include all disclosures required by U.S. GAAP for complete financial statements.

Significant Accounting Policies and Recent Accounting Pronouncements	2. Significant Accounting Policies and Recent Accounting Pronouncements Significant Accounting Policies No material changes have been made to the Company's significant accounting policies disclosed in Note 2, Significant Accounting Policies and Recent Accounting Pronouncements Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) Additionally, ASU No. 2019-10 defers the effective date for the adoption of the new standard on credit losses for public filers that are considered small reporting companies as defined by the SEC to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, which will be fiscal 2023 for the Company if it continues to be classified as a smaller reporting company. In February 2020, the FASB issued ASU 2020-02, which provides guidance regarding methodologies, documentation, and internal controls related to expected credit losses. The subsequent amendments will have the same effective date and transition requirements as ASU No. 2016-13. Early adoption is permitted. Topic 326 requires a modified retrospective approach by recording a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. While the Company is currently evaluating the impact of Topic 326, the Company does not expect the adoption of the ASU to have a material impact on its consolidated financial statements. In December 2019, FASB issued ASU 2019-12, Income Taxes (740), Simplifying the Accounting for Income Taxes

Revenue From Contract With Customer [Abstract]
Revenue	3. Revenue Revenue Recognition Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company enters into contracts that can include various combinations of its products, software licenses, and services, which are generally capable of being distinct and accounted for as separate performance obligations. For contracts with multiple performance obligations, the Company allocates the transaction price of the contract to each performance obligation, generally on a relative basis using its standalone selling price. The stated contract value is generally the transaction price to be allocated to the separate performance obligations. Revenue is recognized net of any taxes collected from customers that are subsequently remitted to governmental authorities. Nature of Products and Services The Company derives revenues from sales of hardware products, software licenses, subscriptions, professional services, software maintenance and support, and extended hardware warranties. Hardware Product Revenue — Guarantees Software License Revenue — Subscription Revenue the right to take possession of the software supporting the subscription service, or if applicable, any hardware devices at any time during the contract period, and as such are not considered separate performance obligations. Revenue is recognized ratably on a straight-line basis over the term of the contract beginning when the service is made available to the customer. Subscription contract terms range from month-to-month to six years in length and billed monthly or annually. Professional Services Revenue — Software Maintenance and Support Revenue — Extended Hardware Warranties Revenue — two Performance Obligation When Performance Obligation is Typically Satisfied When Payment is Typically Due How Standalone Selling Price is Typically Estimated Hardware products When customer obtains control of the product (point-in-time) Within 30-60 days of shipment Observable in transactions without multiple performance obligations Software licenses When license is delivered to customer or made available for download, and the applicable license period has begun (point-in-time) Within 30-60 days of the beginning of license period Established pricing practices for software licenses bundled with software maintenance, which are separately observable in renewal transactions Subscriptions Ratably over the course of the subscription term (over time) In advance of subscription term Contractually stated or list price Professional services As services are performed and/or when contract is fulfilled (point-in-time) Within 30-60 days of delivery Observable in transactions without multiple performance obligations Software maintenance and support services Ratably over the course of the support contract (over time) Within 30-60 days of the beginning of the contract period Observable in renewal transactions Extended hardware warranties Ratably over the course of the support contract (over time) Within 30-60 days of the beginning of the contract period Observable in renewal transactions Significant Judgments The Company’s contracts with customers often include promises to transfer multiple products and services to a customer. For such arrangements, the Company allocates the transaction price to each performance obligation based on its relative standalone selling price (“SSP”). Judgment is required to determine the SSP for each distinct performance obligation in a contract. For the majority of items, the Company estimates SSP using historical transaction data. The Company uses a range of amounts to estimate SSP when it sells each of the products and services separately and needs to determine whether there is a discount to be allocated based on the relative SSP of the various products and services. In instances where SSP is not directly observable, such as when the product or service is not sold separately, the Company determines the SSP using information that may include market conditions and other observable inputs. The determination of SSP is an ongoing process and information is reviewed regularly in order to ensure SSPs reflect current information or trends. Disaggregation of Revenue The Company disaggregates revenue from contracts with customers based on the timing of transfer of goods or services to customers (point-in-time or over time) and geographic region based on the shipping location of the customer. The geographic regions that are tracked are the Americas, Europe and the Middle East, and Asia-Pacific regions. Total net revenue based on the disaggregation criteria described above is as follows (in thousands): Three Months Ended March 31, 2021 2020 Point-in- Time Over Time Total Point-in- Time Over Time Total Americas $ 14,396 $ 752 $ 15,148 $ 12,705 $ 1,163 $ 13,868 Europe and the Middle East 2,364 96 2,460 2,504 97 2,601 Asia-Pacific 4,554 — 4,554 1,651 — 1,651 Total $ 21,314 $ 848 $ 22,162 $ 16,860 $ 1,260 $ 18,120 Contract Balances Amounts invoiced in advance of services being provided are accounted for as deferred revenue. Nearly all of the Company’s deferred revenue balance is related to software maintenance contracts. Payment terms and conditions vary by contract type, although payment is typically due within 30 to 90 days of contract inception. In instances where the timing of revenue recognition differs from the timing of invoicing, the Company has determined its contracts do not include a significant financing component. The primary purpose of the Company’s invoicing terms is to provide customers with simplified and predictable ways of purchasing the Company’s products and services, not to receive financing from its customers. Changes in deferred revenue during the three months ended March 31, 2021 and March 2020 were as follows (in thousands): Three Months Ended March 31, 2021 2020 Deferred revenue, beginning of period $ 2,366 $ 2,833 Deferral of revenue billed in current period, net of recognition 392 384 Recognition of revenue deferred in prior periods (793 ) (931 ) Deferred revenue as, end of period $ 1,965 $ 2,286 Unsatisfied Performance Obligations Revenue expected to be recognized in future periods related to remaining performance obligations, excluding revenue pertaining to contracts that have an original expected duration of one year or less, and contracts where revenue is recognized as invoiced, was approximately $0.8 million as of March 31, 2021. Since the Company typically invoices customers at contract inception, this amount is included in the deferred revenue balance. As of March 31, 2021, the Company expects to recognize 53% of the revenue related to these unsatisfied performance obligations during the remainder of 2021, 32% during 2022, and 15% thereafter. Assets Recognized from the Costs to Obtain a Contract with a Customer The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if it expects the benefit of those costs to be longer than one year. The Company has determined that certain sales incentive programs (i.e., commissions) meet the requirements to be capitalized. Capitalized incremental costs related to contracts are amortized over the respective contract periods. For the three months ended March 31, 2021, total capitalized costs to obtain contracts were immaterial.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	4. Fair Value Measurements The Company determines the fair values of its financial instruments based on a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The classification of a financial asset or liability within the hierarchy is based upon the lowest level input that is significant to the fair value measurement. Under ASC 820, Fair Value Measurement and Disclosures (“ASC 820”) • Level 1 – Quoted prices (unadjusted) for identical assets and liabilities in active markets; • Level 2 – Inputs other than quoted prices in active markets for identical assets and liabilities that are observable either directly or indirectly; and • Level 3 – Unobservable inputs. Assets and Liabilities Measured at Fair Value on a Recurring Basis As of March 31, 2021 and December 31, 2020, the only assets measured and recognized at fair value on a recurring basis were nominal cash equivalents. As of March 31, 2021 and December 31, 2020, there were no liabilities measured and recognized at fair value on a recurring basis, other than contingent consideration related to prior acquisitions as of December 31, 2020 which had no fair value. Assets and Liabilities Measured at Fair Value on a Non-recurring Basis Certain of the Company's assets, including goodwill, intangible assets, and privately-held investments, are measured at fair value on a nonrecurring basis if impairment is indicated. Purchased intangible assets are measured at fair value primarily using discounted cash flow projections. For additional discussion of measurement criteria used in evaluating potential impairment involving goodwill and intangible assets, refer to Note 5, Goodwill and Intangible Assets As of March 31, 2021 $ As of March 31, 2021 and December 31, 2020, there were no liabilities that are measured and recognized at fair value on a non-recurring basis. Assets and Liabilities Not Measured at Fair Value The carrying amounts of the Company's accounts receivable, prepaid expenses and other current assets, accounts payable, and other accrued liabilities approximate fair value due to their short maturities. The carrying value of the Company’s financial liabilities approximates fair value based upon borrowing rates currently available to the Company for loans with similar terms.

Following subsequent amendments, on February 8, 2021 the Company amended and restated the Loan and Security Agreement in its entirety (the “Loan and Security Agreement”). The Loan and Security Agreement provides for a $20.0 million revolving loan facility subject to a borrowing base and a $4.0 million non-formula revolving loan facility that is not subject to a borrowing base. The Company’s obligations under the Loan and Security Agreement are collateralized by substantially all of its assets. The maturity date of the main revolving loan facility is February 8, 2023. The non-formula revolving loan facility will terminate on February 7, 2022, however the Company may, at its option if certain conditions are met, convert prior to their maturity any loans under the non-formula revolving loan facility to a term loan that will fully amortize and mature on February 1, 2025. Advances under the revolving loan facilities and the term loan (if converted) will initially bear interest at a per annum rate equal to the prime rate as determined under the Loan and Security Agreement plus 0.25%. On April 30, 2021, the Company entered into an amendment to its Loan and Security Agreement which reduced the per annum interest rate to the prime interest rate. The Company may voluntarily prepay amounts outstanding under the revolving loan facilities and the term loan without prepayment charges. In the event the Loan and Security Agreement is terminated prior to February 8, 2023, the Company would be required to pay an early termination fee in the amount of 2.0% of the main revolving loan line if terminated prior to February 8, 2022 and 1% of the main revolving loan line thereafter. Additional borrowing requests under the revolving loan facilities are subject to various customary conditions precedent, including a borrowing base for the main revolving loan facility. The Loan and Security Agreement contains customary representations and warranties and customary affirmative and negative covenants, including, limits or restrictions on the Company’s ability to incur liens, incur indebtedness, make certain restricted payments (including dividends), merge or consolidate and dispose of assets. In addition, the Loan and Security Agreement contains financial covenants requiring that the Company (i) hold $5 million in unrestricted cash in accounts with EWB, (ii) maintain a monthly minimum trailing six-month EBITDA of $0.6 million for the first two quarters of 2021 and $1.2 million thereafter and (iii) maintain, if the Company converts into the term loan and starting with the quarter ending March 31, 2022, a quarterly fixed charge coverage ratio of at least 1.35:1.00. The Loan and Security Agreement contains customary events of default that entitle EWB to cause any or all of the Company’s indebtedness under it to become immediately due and payable. The events of default (some of which are subject to applicable grace or cure periods), include, among other things, non-payment defaults, covenant defaults, cross-defaults to other material indebtedness, bankruptcy and insolvency defaults and material judgment defaults. Upon the occurrence and during the continuance of an event of default, EWB may terminate its lending commitment and/or declare all or any part of the unpaid principal of all loans, all interest accrued and unpaid thereon and all other amounts payable under the Loan and Security Agreement to be immediately due and payable. As of March 31, 2021, the Company was in compliance with all financial covenants under the Revolving Loan Facility. April 21 Funds On May 5, 2020, the Company issued secured subordinated promissory notes in an aggregate principal amount of $4.0 million (the “Notes”) to 21 April Fund, LP and 21 April Fund, Ltd. (collectively referred to as the “April 21 Funds”) pursuant to a Note and Warrant Purchase Agreement entered into with the April 21 Funds (the “Note Purchase Agreement”). The Notes are collateralized by the Company’s assets, but subordinate to the Company’s obligations to EWB under its Loan and Security Agreement. Proceeds from the sale of the Notes were only to be used for expenses incurred by the Company in connection with its provisions of goods and services under a statement of work with a third party. The Notes have an initial term of nine months and do not bear interest during this period. If the Notes are not repaid on or before the nine-month anniversary of issuance, (a) the Notes will thereafter bear interest of 8% per annum, payable quarterly, and (b) additional warrants to purchase common stock would be issuable to the April 21 Funds for each month all or a portion of the Notes remain unpaid, as further detailed in the Note Purchase Agreement. In the event the Notes are not paid in full by the first anniversary of their issuance, May 5, 2021, they shall thereafter bear interest of 12% per annum, payable quarterly, and additional warrants would be issuable to the April 21 Funds. As discussed in Note 10, Stockholders’ Equity, On February 5, 2021, the Company entered into an amendment to the secured subordinated promissory note with April 21 Funds, which extended the initial term of the Notes to March 31, 2021. As a result of the amendment, if the Notes were repaid on or before March 31, 2021, the Company would incur no further interest on the Notes, or be obligated to issue additional warrants. As of March 31, 2021, the principal amount outstanding under the Notes was $2.8 million. On March 31, 2021, April 21 Funds waived any additional warrants issuable, and interest payable, to April 21 Funds through May 5, 2021. On April 13, 2021, the Company repaid the remaining principal amount outstanding of $2.8 million. Paycheck Protection Program On April 9, 2020, the Company entered into a promissory note (the “PPP Note”) under the Paycheck Protection Program established under Section 1102 of the Coronavirus Aid, Relief and Economic Security (“CARES”) Act. The PPP Note is dated April 8, 2020 with EWB. The Company borrowed a principal amount of approximately $2.9 million. The interest on the PPP Note is 1.0% per annum. The PPP Note is payable two years from the date of the PPP Note, and there is no prepayment penalty. All interest which accrues during the initial six months of the loan period is deferred and payable on the maturity date of the PPP Note. Notes issued under the CARES Act may be eligible for forgiveness in whole or in part in accordance with Small Business Administration rules established for the Paycheck Protection Program. The principal amount outstanding, including accrued interest, is included in current portion – financial liabilities and other accrued expenses and liabilities in the accompanying condensed consolidated balance sheets, as the Company expects all amounts outstanding will be forgiven in 2021.

Income Taxes	9. Income Taxes The Company conducts business globally and, as a result, files federal, state and foreign tax returns. The Company strives to resolve open matters with each tax authority at the examination level and could reach agreement with a tax authority at any time. While the Company has accrued for amounts it believes are the probable outcomes, the final outcome with a tax authority may result in a tax liability that is more or less than that reflected in the condensed consolidated financial statements. Furthermore, the Company may later decide to challenge any assessments, if made, and may exercise its right to appeal. The Company applies the provisions of, and accounted for uncertain tax positions in accordance with ASC 740, Income Taxes The Company generally is no longer subject to tax examinations for years prior to 2016. However, if loss carryforwards of tax years prior to 2016 are utilized in the U.S., these tax years may become subject to investigation by the tax authorities. While timing of the resolution and/or finalization of tax audits is uncertain, the Company does not believe that its unrecognized tax benefits would materially change in the next 12 months. On March 11, 2021, President Biden signed the American Rescue Plan Act of 2021 (the “Act”) into law. The $1.9 trillion Act includes COVID-19 relief, as well as broader stimulus, but also includes several revenue-raising and business tax provisions. The CARES Act also includes several significant provisions for corporations, including the usage of net operating losses and payroll benefits. Several foreign (non-U.S.) jurisdictions in which we operate have taken similar economic stimulus measures. The Act and the CARES Act had no material impact on the Company’s condensed consolidated financial statements and disclosures.
