Cisco is in advanced talks to acquire Israeli cybersecurity startup Astrix Security for $250M-$350M, per Calcalist and multiple sources. Astrix specializes in non-human identity (NHI) security for AI agents, with a four-method discovery architecture unveiled at RSAC 2026 that surfaces shadow agents via platform integrations, NHI fingerprinting, EDR telemetry, and BYOS. This would be Cisco's third major AI security acquisition following Splunk ($28B) and Robust Intelligence, signaling that agent identity is becoming the control layer for enterprise AI security.
