Profile
Sells network observability and service-assurance software, appliances, and support to enterprises, communications carriers, and public agencies, while Arbor and Omnis products detect and mitigate DDoS attacks and investigate network threats. Deep packet inspection supplies the shared data layer, and service revenue exceeds product revenue.
Turns packet-level network traffic into operational data for large enterprises, communications service providers, and public-sector organizations worldwide. The nGenius service assurance portfolio monitors application and network performance, while Arbor detects and mitigates DDoS attacks and Omnis supports network threat investigation.
Combines software, purpose-built appliances, virtual sensors, packet-flow systems, and cloud-based protection. Deep packet inspection at scale supplies a shared data layer across legacy, hybrid, cloud-native, and mobile environments, helping operations teams isolate performance failures and security events.
Sells products directly and through resellers and systems integrators, then earns service revenue from maintenance, support, cloud subscriptions, and professional services. Demand depends on continued customer investment in network visibility and attack protection; service revenue exceeds product revenue.

Ownership
A 13F quarter can total more than the shares outstanding — sub-advisers file the same block twice, and a filer's own share count can be a quarter stale. No split is drawn from it.
