Stamus Networks

Stamus Networks, founded in 2014, builds network detection and response (NDR) technology under the Clear NDR brand (formerly the Stamus Security Platform), built on top of the open-source Suricata intrusion detection engine that the company’s founders help maintain. The platform inspects network traffic to surface threats, generate rich metadata for hunting, and provide detection logic that customers can inspect and tune rather than treat as an opaque black box.

The company positions its Suricata-based, rules-transparent approach as a differentiator against proprietary NDR vendors whose detection logic is not inspectable by the customer, branding this openness as "Clear NDR." Stamus lists Indianapolis, Indiana as its U.S. office alongside a Paris, France location that reflects its European engineering roots and Suricata community ties.

Stamus Networks has raised roughly $11 million total, including a $6 million Series A round in 2023 led by First Analysis with participation from SmoothBrain, funding levels that keep it a small, focused player rather than a scaled NDR incumbent. For SOC and network security teams that want transparent, tunable detection logic and Suricata-native integration rather than a closed proprietary engine, Stamus is a credible niche alternative to larger NDR platforms, though its funding and headcount are modest relative to well-capitalized competitors like Darktrace, Vectra, or Corelight.
