What is Stamus Networks?

Stamus Networks develops Clear NDR, a network detection and response platform formerly marketed as the Stamus Security Platform. It is built on the open-source Suricata IDS/IPS engine and combines intrusion detection, network security monitoring, and NDR using signature-based, anomaly-based, and behavioral methods. It is offered as a commercial Enterprise edition and a free open-source Community edition, the successor to the SELKS project. The company also maintains the Suricata-based open-source tooling that underpins its commercial offering.
