Segment Reporting [Abstract]  
SEGMENT AND GEOGRAPHIC INFORMATION SEGMENT AND GEOGRAPHIC INFORMATION
The Company's operating segments are determined based on the units that constitute a business for which discrete financial information is available and for which operating results are regularly reviewed by the CODM. The Company's President and CEO is the CODM. Operating results are reviewed by the CODM primarily at the consolidated entity level for the purpose of making resource allocation decisions and for evaluating financial performance, primarily by monitoring actual results compared to forecasted results as well as by reviewing year-over-year results. The Company's CODM evaluates company-wide performance and determines allocation of resources based on multiple performance measures, including but not limited to net income (loss).
The Company has determined it operates as a single operating segment and has one reportable segment which includes product and service revenue related to the sale of enterprise performance management, carrier service assurance, cybersecurity, and DDoS protection solutions. The Company's results for the one reportable segment are the same as presented in the Company's consolidated statements of operations and there is no expense information that is supplemental to those disclosed in these consolidated financial statements, that are regularly provided to the CODM. The measure of segment assets is reported on the Company's consolidated balance sheet as total assets. Segment asset information is not used by the CODM to allocate resources.

The United States revenue includes sales to resellers in the United States. These resellers fulfill customer orders and may subsequently ship the Company's products to international locations. Further, the Company determines the geography of its sales after considering where the contract originated. A majority of revenue attributable to locations outside of the United States is a result of export sales. Substantially all of the Company's identifiable assets are located in the United States.
