What TransNexus does
TransNexus is a privately held Atlanta-based software company that develops telecom network management and protection platforms for voice service providers, managed service providers, and enterprises. Founded in 1997 and operating continuously since, the company sells three core products: ClearIP, a cloud-hosted telecom platform providing fraud prevention, robocall and TDoS mitigation, jurisdictional and least-cost routing, STIR/SHAKEN caller authentication, and CNAM services; NexOSS, an on-premises VoIP application suite for intelligent least-cost routing, quality-of-service monitoring, billing analytics, and STIR/SHAKEN; and CDRAnalyzer, a call detail record analytics and reporting tool. Underlying capabilities include the proprietary SIP Analytics technology, which inspects SIP messages in real time before call setup to detect and block telecom fraud attacks faster than CDR-based alternatives.
The company monetizes through subscription licensing of ClearIP (cloud-hosted SaaS) and NexOSS (on-premises) under quote-based enterprise pricing, supported by free trials with technical onboarding. TransNexus is an FCC-recognized SHAKEN Certification Authority (STI-CA) and operates a STIR/SHAKEN statistics program aggregating data from 100+ voice service providers, providing thought leadership and ecosystem visibility. Distribution is primarily direct enterprise field sales, supplemented by channel partnerships (ACG, TIP Solutions) targeting wireless carriers for Branded Calling ID deployments, and technology integrations with Telinta, DigiCert, Somos, Cisco BroadWorks, Oracle Acme Packet, Ribbon, and Metaswitch. The company also offers enterprise-targeted solutions for TDoS prevention and robocall blocking, and serves international customers (e.g., Linkt in France) under non-U.S. robocall mitigation programs. The company holds CSA STAR Level 1, GDPR, and PCI DSS compliance certifications.
