Competitive landscape
Edge: Leadership from Mandiant/Trustwave plus rapid revenue traction ($10M in six months) — rare velocity for cybersecurity services startups.
MDR is a services-heavy market being reshaped by AI automation. Tenex must prove unit economics at scale while incumbents embed AI into existing SOC contracts.
-
Arctic Wolf direct
Managed detection and response at scale; less AI-native positioning.
-
CrowdStrike Falcon Complete incumbent
Vendor-native MDR bundled with EDR platform.
-
Expel direct
Managed SOC with human analysts; different AI automation depth.
