Featured Highlights
TWO PORTFOLIO COMPANIES RECOGNIZED IN RISING IN CYBER
Rain Capital portfolio companies ProjectDiscovery and Clover Security were recognized on the 2026 Rising in Cyber List by Notable Capital. As AI reshapes how software is built and deployed, both companies reflect the growing shift toward more autonomous, AI-native security infrastructure embedded directly into modern development workflows.
CISCO TO ACQUIRE ASTRIX SECURITY IN REPORTED ~$400M DEAL
Cisco announced its acquisition of Astrix Security in a reported ~$400M transaction, marking Rain Capital’s third exit in six months following Lakera and SPLX. As enterprises adopt AI agents and autonomous systems, Astrix built a platform focused on securing non-human identities, including service accounts, APIs, and AI-driven workflows across modern enterprise environments.
EXPLOITBENCH TRACKS THE RISE OF AI-DRIVEN EXPLOITATION
Rain Venture Partner and Carnegie Mellon University Professor Dr. David Brumley and Ph.D. student Seunghyun Lee launched ExploitBench, a benchmark measuring how AI systems progress through real-world software exploitation workflows. Tested against 41 real V8 vulnerabilities, the benchmark highlights how frontier models are increasingly capable of autonomous, multi-stage offensive operations.
