Accounting Policies [Abstract]
BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2: BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. The condensed consolidated balance sheet as of December 31, 2021 was derived from the audited consolidated financial statements as of that date, but does not include all of the disclosures, including certain notes required by U.S. GAAP on an annual reporting basis. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2021, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on February 25, 2022. In management’s opinion, other than the changes to accounting for leases as described in Note 6, the unaudited condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements with normal recurring adjustments necessary for the fair presentation of the Company’s financial position as of March 31, 2022, and the Company’s consolidated results of operations, convertible and redeemable convertible preferred stock and stockholders’ equity (deficit), and cash flows for the three months ended March 31, 2022 and 2021. The results for the three months ended March 31, 2022, are not necessarily indicative of the results to be expected for the full year ending December 31, 2022, or any other future interim or annual period. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company evaluates on an ongoing basis its assumptions, including those related to contingencies, income tax uncertainties, incremental borrowing rate for operating leases, fair value of financial assets and liabilities, including fair value of derivatives, fair value and useful life of intangible assets, as well as in estimates used in applying the revenue recognition policy. The Company bases these estimates on historical and anticipated results, trends and various other assumptions that it believes are reasonable under the circumstances, including assumptions as to future events. Actual results could differ from those estimates. Concentration of Risks Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, restricted cash and trade receivables. The majority of the Company’s cash, and cash equivalents and restricted cash are invested with major banks in the United States, Israel, and the United Kingdom. Such investments in the United States may be in excess of insured limits and they are not insured in other jurisdictions. In general, these investments may be redeemed upon demand and therefore bear minimal risk. The Company’s trade receivables are geographically dispersed and derived from sales to customers mainly in the United States, Europe, and Asia. Concentration of credit risk with respect to trade receivables is limited by credit limits, ongoing credit evaluation, and account monitoring procedures. Major customer data as a percentage of total revenues: The following table sets forth customers that represented 10% or more of the Company’s total revenue in each of the periods set forth below: Three months ended March 31, 2022 2021 Customer A (M&T) *) — 10.10 % Customer B (EE&T) *) — 10.09 % *) Represents an amount that is lower than 10% of the Company's total revenue. Significant Accounting Policies and Estimates The Company’s significant accounting policies are discussed in Note 2 of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, which was filed with the SEC on February 25, 2022. There have been no significant changes to these policies during the three months ended March 31, 2022 except as noted below. Derivatives and Hedging Derivatives are recognized at fair value as either assets or liabilities in the consolidated balance sheets in accordance with ASC Topic 815, “Derivatives and Hedging.” The gain or loss of derivatives which are designated and qualify as hedging instruments in a cash flow hedge, is recorded under accumulated other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Derivatives are classified within Level 2 of the fair value hierarchy as the valuation inputs are based on quoted prices and market observable data of similar instruments. Recently Adopted Accounting Pronouncements As an “emerging growth company”, the Jumpstart Our Business Startups Act (“JOBS Act”) allows the Company to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. The Company has elected to use this extended transition period under the JOBS Act. The adoption dates discussed below reflect this election. In February 2016, the Financial Accounting Standards (“FASB”) issued ASU No. 2016-02, Leases (Topic 842), which would require lessees to put all leases on their balance sheets, whether operating or financing, while continuing to recognize the expenses on their income statements in a manner similar to the existing practice. The guidance states that a lessee would recognize a lease liability for the obligation to make lease payments and a right-of-use (“ROU”) asset for the right to use the underlying asset for the lease term. The Company adopted the guidance on January 1, 2022 using a modified retrospective transition approach. It applied Topic 842 to all leases as of January 1, 2022 without adjusting the comparative periods presented. The Company elected certain practical expedients permitted under the transition guidance within the new guidance and carried forward the historical accounting relating to lease identification and classification, remaining lease terms, and initial direct costs. Upon adoption, the Company recognized operating lease right-of-use assets and corresponding lease liabilities of $823. The adoption of Topic 842 did not have a material impact to the Company’s results of operations or cash flows. See Note 6, Leases, for further information. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing a variety of exceptions within the framework of ASC 740. These exceptions include the exception to the incremental approach for intra-period tax allocation in the event of a loss from continuing operations and income or a gain from other items (such as other comprehensive income), and the exception to using general methodology for the interim period tax accounting for year-to-date losses that exceed anticipated losses. The guidance will be effective for the Company beginning January 1, 2022, and interim periods in fiscal years beginning January 1, 2023. Early adoption is permitted. The Company adopted this guidance on January 1, 2022, and the adoption did not have a material impact on its consolidated financial statements. Recently Issued Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaces the existing incurred loss impairment model with an expected credit loss model and requires a financial asset measured at amortized cost to be presented at the net amount expected to be collected. The guidance will be effective for the Company beginning January 1, 2023, and interim periods therein. Early adoption is permitted. The Company is currently evaluating the effect that ASU 2016-13 will have on its consolidated financial statements and related disclosures. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires an acquirer in a business combination to recognize and measure contract assets and contract liabilities in accordance with Accounting Standards Codification Topic 606. ASU 2021-08 is effective for fiscal years beginning after December 15, 2022 and early adoption is permitted. While the Company is continuing to assess the timing of adoption and the potential impacts of ASU 2021-08, it does not expect ASU 2021-08 to have a material effect, if any, on its consolidated financial statements.

Foreign currency derivative contracts are classified within the Level 2 value hierarchy, as the valuation inputs are based on quoted prices and market observable data of similar instruments. Fair value measurements as of Description Fair Value Hierarchy March 31, 2022 December 31, 2021 Measured at fair value on a recurring basis: Assets: Cash equivalents: Money market funds Level 1 $ 40,001 $ — Derivative instruments asset included in prepaid expenses and other current assets: Options and forward contracts designated as hedging instruments   Level 2 $ 523 $ — Prior to the Company's initial public offering (the "IPO"), the warrants to purchase preferred and common stock were measured at fair value using Level 3 inputs upon issuance and at each reporting date. Inputs used to determine the estimated fair value of the warrants to purchase preferred and common stock as of the valuation date included expected term, the risk-free interest rate, volatility, and the fair value of underlying shares. T he following table sets forth a summary of the changes in the fair value of the warrants to purchase preferred and common stock: Three Months Ended March 31, 2021 Balance at January 1 $ 56,780 Reclassification of warrant to preferred stocks to mezzanine equity (1,149) Change in fair value of warrants 4,151 Balance at March 31, 2021 $ 59,782 On February 3, 2021, SVB Financial Group (“SVB”) converted a Warrant to Purchase Stock issued on February 3, 2011 (the “Series C Warrant”) into shares of the Company’s Series C Convertible Preferred Stock pursuant to the cashless conversion mechanism described in the Series C Warrant. The conversion was exercised for all 31,414 shares covered by the Series C Warrant and resulted in the net issuance of 27,011 shares of the Company’s Series C Convertible Preferred Stock. Pursuant to the terms of the Series C Warrant, the number of net shares issued was determined by dividing (a) the aggregate fair market value of the shares otherwise issuable upon exercise of the Series C Warrant minus the aggregate exercise price of such shares by (b) the fair market value of one share of the Company’s Series C Convertible Preferred Stock.

LEASES

LEASES	3 Months Ended

Leases [Abstract]
LEASES	NOTE 6: LEASES The Company leases its office facilities under non-cancelable agreements that expire at various dates through July 2027. The Company determines if an arrangement is a lease at inception. As discussed in Note 2, operating lease right-of-use assets and liabilities are included on the Condensed Consolidated Balance Sheet beginning January 1, 2022. The Company currently has finance leases in an immaterial amount that will expire during the fourth quarter of 2022. Operating lease right-of-use assets and liabilities are recognized at the present value of the future lease payments at the lease commencement date. Operating lease right-of-use assets also include any prepaid lease payments and lease incentives. Certain lease agreements include rental payments adjusted periodically for the consumer price index ("CPI"). The right-of-use and lease liability were calculated using the initial CPI and will not be subsequently adjusted. Payments for variable lease costs are expensed as incurred and not included in the operating lease right-of-use assets and liabilities. For short-term leases with a term of 12 months or less, operating lease right-of-use assets and liabilities are not recognized and the Company records lease payments in the Condensed Consolidated Statements of Operations on a straight-line basis over the lease term. The Company combines its lease payments and fixed payments for non-lease components and account for them together as a single lease component. The interest rate used to determine the present value of the future lease payments is the Company’s incremental borrowing rate, because the interest rate implicit in the Company’s leases is not readily determinable. The Company’s incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located. Many of the Company’s lease agreements provide one or more options to renew. When determining lease terms, the Company uses the non-cancellable period of the leases and does not assume renewals unless it is reasonably certain that the Company will exercise the renewal option. Operating lease expenses are recognized on a straight-line basis over the lease term. Components of operating lease expense were as follows: Three Months Ended March 31, 2022 Operating lease cost $ 625 Short-term lease cost — Variable lease cost 12 Total $ 637 Rent expense under the previous lease accounting standard was $548 during the three months ended March 31, 2021. Supplementary cash flow information related to operating leases was as follows: Three Months Ended March 31, 2022 Cash paid for operating leases $ 467 As of March 31, 2022, the weighted-average discount rate is 2.3% and the weighted-average remaining term is 5.30 years. Maturities of the Company’s operating lease liabilities as of March 31, 2022 were as follows: Year Ending December 31, 2022 (Remainder) $ 751 2023 790 2024 808 2025 863 2026 921 2027 471 Total operating lease payments 4,604 Less: imputed interest 505 Total operating lease liabilities $ 4,099 On April 6, 2022, after the balance sheet date, the Company entered into a lease agreement as tenant related to a property in Israel (the "Lease"). The Lease provides that the Company will lease a new building containing approximately 5,926 square meters. The initial lease term is approximately 5.5 years with two options to extend of five years each. The Company believes that it is reasonably certain that it will exercise the option for the first extension period, and accordingly will include this extension period as part of the lease term. The total payments that the Company expects to pay over the initial lease term and the first extension period are approximately $26,419. The lease term is expected to commence in the second quarter of 2022. As of December 31, 2021, the minimum lease payments under operating leases, including payments for leases which had not commenced, were as follows: Year Ending December 31, Rental of premises 2022 $ 1,317 2023 788 2024 806 2025 862 2026 919 2027 548 Total $ 5,240

Income Tax Disclosure [Abstract]
INCOME TAXES	NOTE 10: INCOME TAXES The Company recognized an income tax expense of $2,086 and $1,806 for the three months ended March 31, 2022, and 2021, respectively. The tax expense for these periods was primarily attributable to pre-tax foreign earnings. The Company’s effective tax rates of (14)% and (13)% for the three months ended March 31, 2022 and 2021, respectively, differ from the U.S. statutory tax rate primarily due to U.S. losses for which there is no benefit and the tax rate differences between the U.S. and foreign countries. The Company has a full valuation allowance on its deferred tax assets. As a result, consistent with the prior year, the Company does not record a tax benefit on its losses because it is more likely than not that the benefit will not be realized.

REPORTABLE SEGMENTS AND GEOGRAPHICAL INFORMATION	NOTE 12: REPORTABLE SEGMENTS AND GEOGRAPHICAL INFORMATION Reportable segments ASC 280, Segment Reporting, establishes standards for reporting information about operating segments. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company's chief operating decision maker ("CODM") is its Chief Executive Officer. The Company's CODM does not regularly review asset information by segments and, therefore, the Company does not report asset information by segment. The Company organizes its operations in two segments: Enterprise, Education and Technology and Media and Telecom. The Enterprise, Education and Technology segment represents products related to industry solutions for education customers, and media services (except for Media and Telecom customers). The Media and Telecom segment primarily represents TV solutions that are sold to media and telecom operators. The measurement of the reportable operating segments is based on the same accounting principles applied in these financial statements, which includes certain corporate overhead allocations.

Debt Disclosure [Abstract]
LONG-TERM LOAN	NOTE 13: LONG-TERM LOAN In January 2021, the Company refinanced all amounts outstanding under the existing loan agreements, terminated all outstanding commitments, and entered into a new credit agreement (the “Credit Agreement”) with an existing lender, which provides for a new senior secured term loan facility in the aggregate principal amount of $40,000 (the “Term Loan Facility”) and a new senior secured revolving credit facility in the aggregate principal amount of $10,000 (the “Revolving Credit Facility” and, together with the Term Loan Facility, the “Credit Facilities”). In June 2021, the Company entered into an amendment to the Credit Agreement (the “First Amendment”). Pursuant to the First Amendment, the Company borrowed an additional aggregate principal amount of $12,500 and increased commitments under the Revolving Credit Facility to $35,000. In December 2021, the Company repaid in full its outstanding principal amount under the Revolving Credit Facility. As of March 31, 2022 and December 31, 2021, the total commitments under the Revolving Credit Facility are available for future borrowings. Borrowings under the Credit Facilities are subject to interest, determined as follows: (a) Eurodollar loans accrue interest at a rate per annum equal to the Eurodollar rate plus a margin of 3.50% (the Eurodollar rate is calculated based on the Credit Agreement, subject to a 1.00% floor, divided by 1.00 minus the maximum effective reserve percentage for Eurocurrency funding), and (b) Alternate Base Rate (“ABR”) loans accrue interest at a rate per annum equal to the ABR plus a margin of 2.50% (ABR is equal to the highest of (i) the prime rate and (ii) the Federal Funds Effective Rate plus 0.50%, subject to a 2.00% floor). As of March 31, 2022, the current rate of interest under the Credit Facilities was equal to a rate per annum of 4.50%, consisting of the 1.00% floor and the margin of 3.50%. The Term Loan Facility is payable in consecutive quarterly installments on the last day of each fiscal quarter in an amount equal to (i) $250 for installments payable on April 1, 2021, through December 31, 2021 (ii) $750 for installments payable on March 31, 2022 through December 31, 2022, and (iii) $1,500 for installments payable on and after March 31, 2023. The remaining unpaid balance on the Term Loan Facility is due and payable on January 14, 2024, together with accrued and unpaid interest on the principal amount to be paid to, but excluding, the payment date. Amounts outstanding under the Credit Facilities may be voluntarily prepaid at any time and from time to time, in whole or in part, without premium or penalty. Under the terms of the Credit Facilities, the Company is obligated to maintain certain covenants as defined therein. As of March 31, 2022, the Company met these covenants. The aggregate principal annual maturities according to the Credit Facilities agreements are as follows: Year Ending December 31, 2022 (Remainder) $ 2,250 2023 6,000 2024 30,000 $ 38,250 The carrying amounts of the loans approximate their fair value.

BASIS OF PRESENTATION AND SUM_2

BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
	Mar. 31, 2022
Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. The condensed consolidated balance sheet as of December 31, 2021 was derived from the audited consolidated financial statements as of that date, but does not include all of the disclosures, including certain notes required by U.S. GAAP on an annual reporting basis. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2021, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on February 25, 2022. In management’s opinion, other than the changes to accounting for leases as described in Note 6, the unaudited condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements with normal recurring adjustments necessary for the fair presentation of the Company’s financial position as of March 31, 2022, and the Company’s consolidated results of operations, convertible and redeemable convertible preferred stock and stockholders’ equity (deficit), and cash flows for the three months ended March 31, 2022 and 2021. The results for the three months ended March 31, 2022, are not necessarily indicative of the results to be expected for the full year ending December 31, 2022, or any other future interim or annual period.
Use of Estimates	Use of EstimatesThe preparation of financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company evaluates on an ongoing basis its assumptions, including those related to contingencies, income tax uncertainties, incremental borrowing rate for operating leases, fair value of financial assets and liabilities, including fair value of derivatives, fair value and useful life of intangible assets, as well as in estimates used in applying the revenue recognition policy. The Company bases these estimates on historical and anticipated results, trends and various other assumptions that it believes are reasonable under the circumstances, including assumptions as to future events. Actual results could differ from those estimates.
Concentration of Risks	Concentration of Risks Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, restricted cash and trade receivables. The majority of the Company’s cash, and cash equivalents and restricted cash are invested with major banks in the United States, Israel, and the United Kingdom. Such investments in the United States may be in excess of insured limits and they are not insured in other jurisdictions. In general, these investments may be redeemed upon demand and therefore bear minimal risk. The Company’s trade receivables are geographically dispersed and derived from sales to customers mainly in the United States, Europe, and Asia. Concentration of credit risk with respect to trade receivables is limited by credit limits, ongoing credit evaluation, and account monitoring procedures. Major customer data as a percentage of total revenues: The following table sets forth customers that represented 10% or more of the Company’s total revenue in each of the periods set forth below: Three months ended March 31, 2022 2021 Customer A (M&T) *) — 10.10 % Customer B (EE&T) *) — 10.09 % *) Represents an amount that is lower than 10% of the Company's total revenue.
Significant Accounting Policies and Estimates	Significant Accounting Policies and Estimates The Company’s significant accounting policies are discussed in Note 2 of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, which was filed with the SEC on February 25, 2022. There have been no significant changes to these policies during the three months ended March 31, 2022 except as noted below.
Derivatives and Hedging	Derivatives and Hedging Derivatives are recognized at fair value as either assets or liabilities in the consolidated balance sheets in accordance with ASC Topic 815, “Derivatives and Hedging.” The gain or loss of derivatives which are designated and qualify as hedging instruments in a cash flow hedge, is recorded under accumulated other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Derivatives are classified within Level 2 of the fair value hierarchy as the valuation inputs are based on quoted prices and market observable data of similar instruments.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements As an “emerging growth company”, the Jumpstart Our Business Startups Act (“JOBS Act”) allows the Company to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. The Company has elected to use this extended transition period under the JOBS Act. The adoption dates discussed below reflect this election. In February 2016, the Financial Accounting Standards (“FASB”) issued ASU No. 2016-02, Leases (Topic 842), which would require lessees to put all leases on their balance sheets, whether operating or financing, while continuing to recognize the expenses on their income statements in a manner similar to the existing practice. The guidance states that a lessee would recognize a lease liability for the obligation to make lease payments and a right-of-use (“ROU”) asset for the right to use the underlying asset for the lease term. The Company adopted the guidance on January 1, 2022 using a modified retrospective transition approach. It applied Topic 842 to all leases as of January 1, 2022 without adjusting the comparative periods presented. The Company elected certain practical expedients permitted under the transition guidance within the new guidance and carried forward the historical accounting relating to lease identification and classification, remaining lease terms, and initial direct costs. Upon adoption, the Company recognized operating lease right-of-use assets and corresponding lease liabilities of $823. The adoption of Topic 842 did not have a material impact to the Company’s results of operations or cash flows. See Note 6, Leases, for further information. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing a variety of exceptions within the framework of ASC 740. These exceptions include the exception to the incremental approach for intra-period tax allocation in the event of a loss from continuing operations and income or a gain from other items (such as other comprehensive income), and the exception to using general methodology for the interim period tax accounting for year-to-date losses that exceed anticipated losses. The guidance will be effective for the Company beginning January 1, 2022, and interim periods in fiscal years beginning January 1, 2023. Early adoption is permitted. The Company adopted this guidance on January 1, 2022, and the adoption did not have a material impact on its consolidated financial statements.
New Accounting Pronouncements Issued	Recently Issued Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaces the existing incurred loss impairment model with an expected credit loss model and requires a financial asset measured at amortized cost to be presented at the net amount expected to be collected. The guidance will be effective for the Company beginning January 1, 2023, and interim periods therein. Early adoption is permitted. The Company is currently evaluating the effect that ASU 2016-13 will have on its consolidated financial statements and related disclosures. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires an acquirer in a business combination to recognize and measure contract assets and contract liabilities in accordance with Accounting Standards Codification Topic 606. ASU 2021-08 is effective for fiscal years beginning after December 15, 2022 and early adoption is permitted. While the Company is continuing to assess the timing of adoption and the potential impacts of ASU 2021-08, it does not expect ASU 2021-08 to have a material effect, if any, on its consolidated financial statements.
