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 consolidated balance sheet as of December 31, 2022 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, 2022, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on February 24, 2023. In management’s opinion, 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 June 30, 2023, and the Company’s consolidated results of operations, stockholders’ equity, and cash flows for the three and six months ended June 30, 2023 and 2022. The results for the three and six months ended June 30, 2023, are not necessarily indicative of the results to be expected for the full year ending December 31, 2023, 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 acquired intangible assets and goodwill, 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, marketable securities, bank deposits, restricted cash and trade receivables. The majority of the Company’s cash, and cash equivalents, marketable securities, bank deposits 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. Market conditions can impact the viability of these financial institutions. In the event of failure of any of the financial institutions where the Company maintains its cash and cash equivalents, there can be no assurance that the Company would be able to access uninsured funds in a timely manner or at all. Any inability to access or delay in accessing these funds could adversely affect the Company's business and financial position. 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 June 30, Six Months Ended June 30, 2023 2022 2023 2022 Customer A (M&T) 10.30 % *) — 10.50 % *) — *) 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, 2022, which was filed with the SEC on February 24, 2023. There have been no significant changes to these policies during the six months ended June 30, 2023 except as noted below. 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 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 Company adopted this guidance using modified retrospective approach, effective on January 1, 2023. The adoption did not have a material effect on its consolidated financial statements.

REPORTABLE SEGMENTS AND GEOGRAPHICAL INFORMATION	NOTE 13: 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.

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 May 2023, the Company entered into an amendment to the Credit Agreement to replace the London Interbank Offered Rate (“LIBOR”) with the Secured Overnight Financing Rate (“SOFR”) as the benchmark rate under the Credit Agreement. Prior to the Fourth Amendment, borrowings under the credit agreement would bear interest, at the Company's election, at (a) the Eurodollar Rate (as defined in the Credit Agreement as in effect prior to the Fourth Amendment) plus a margin of 3.50% or (b) Alternative Base Rate (“ABR”) (as defined in the Credit Agreement) plus a margin of 2.50%. Following the effectiveness of the Fourth Amendment, borrowings under the Credit Facilities bear interest, determined as follows: (a) SOFR loans accrue interest at a rate per annum equal to Term SOFR (aas defined in the Credit Agreement) plus 0.10% per annum plus a margin of 3.50% (the Adjusted Term SOFR (as defined in the Credit Agreement) is subject to a 1.00% floor), and (b) 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 June 30, 2023, the current rate of interest under the Credit Facilities was equal to a rate per annum of 8.84%, consisting of 5.34% (the 3-month SOFR rate as of June 30, 2023), 0.10% credit spread adjustment 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.

BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
	Jun. 30, 2023
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 consolidated balance sheet as of December 31, 2022 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, 2022, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on February 24, 2023. In management’s opinion, 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 June 30, 2023, and the Company’s consolidated results of operations, stockholders’ equity, and cash flows for the three and six months ended June 30, 2023 and 2022. The results for the three and six months ended June 30, 2023, are not necessarily indicative of the results to be expected for the full year ending December 31, 2023, 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 acquired intangible assets and goodwill, 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, marketable securities, bank deposits, restricted cash and trade receivables. The majority of the Company’s cash, and cash equivalents, marketable securities, bank deposits 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. Market conditions can impact the viability of these financial institutions. In the event of failure of any of the financial institutions where the Company maintains its cash and cash equivalents, there can be no assurance that the Company would be able to access uninsured funds in a timely manner or at all. Any inability to access or delay in accessing these funds could adversely affect the Company's business and financial position. 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 June 30, Six Months Ended June 30, 2023 2022 2023 2022 Customer A (M&T) 10.30 % *) — 10.50 % *) — *) 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, 2022, which was filed with the SEC on February 24, 2023. There have been no significant changes to these policies during the six months ended June 30, 2023 except as noted below.
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 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 Company adopted this guidance using modified retrospective approach, effective on January 1, 2023. The adoption did not have a material effect on its consolidated financial statements.
