Cisco will buy WideField Security and fold its identity and session telemetry tech into Splunk’s agentic AI SOC. The deal aims to track human and AI-agent actions in real time, tightening security around automated workflows. It follows Cisco’s recent picks of Astrix Security and Galileo Technologies.

Zscaler unveiled a zero trust platform to secure autonomous AI agents’ data access, communications and device activity. It adds an AI Broker for agent-to-agent and data calls, endpoint AI threat detection, an AI Access Graph for mapping identities and data flows, and expanded AI Protect controls. This aims to give each AI agent its own identity, permissions and real-time monitoring.
