Permiso Security
Permiso Security is a Palo Alto-based cybersecurity company that discovers, protects, and defends identities across cloud and on-prem environments. Founded by former FireEye/Mandiant executives, its identity security platform stitches human, non-human, and AI-agent identities into a single Universal Identity Graph, using 1,400+ detection rules and behavioral analytics to catch account takeovers, credential compromise, and insider threats. Permiso also runs the P0 Labs threat-research team, which has released ten open-source tools including CloudGrappler and YetiHunter.
RAD Security
RAD Security is a San Francisco cloud-native security company that pairs runtime telemetry with agentic AI to help teams detect, investigate, and respond to threats across Kubernetes and cloud environments. Founded in 2021 as KSOC and rebranded RAD Security in 2024, it builds behavioral, eBPF-driven detection and a roster of AI 'RADBots' that triage alerts, generate compliance evidence, and automate security workflows. The company raised a $14M Series A in February 2025, bringing total funding to about $20M.
