detections.ai

detections.ai, rebranded from System Two Security, builds AI tooling for detection engineering: translating threat intelligence into detections, generating and tuning rules, managing detection libraries, and converting detections across platforms such as Splunk, Microsoft Sentinel and CrowdStrike’s Next-Gen SIEM. A free Community tier lets detection engineers share and reuse rules with an AI assistant and MITRE ATT&CK mapping; a paid Enterprise tier adds automated hunting, live coverage tracking against CVEs and ATT&CK, and scheduled library audits. The company has also announced “Nightwatch,” pitched as autonomous hunting and detection engineering.

Founded in 2023 in Palo Alto, California by CEO Robert Fly and CTO Prasanth Ganesan, the company raised a $7 million seed round in December 2024 led by Costanoa Ventures, with Runtime Ventures, The Hive, Webb Investment Network and individual angel investors including Scott McNealy and Frederic Kerrest, followed by an additional, undisclosed round in November 2025 led by new investors Modern Technical Fund Management and S Ventures.

The company states more than 17,000 detection engineers use its platform, a concrete if self-reported adoption figure that distinguishes it from earlier-stage peers in the same AI-for-SOC space.
