Cyera Extended Agent Guardian to the Endpoint, Chasing Local AI Tools Running on Employee Laptops
Cyera introduced Agent Guardian and Cyera Endpoint on August 3 at Black Hat, structured around a four-phase discover, govern, protect, validate framework that continuously inventories AI agents and enforces runtime controls on prompt injection and unauthorized data access. Cyera Endpoint is the more consequential half: it pushes the same guardrails onto local AI tools running directly on employee devices, extending the company beyond browser-based controls to the device layer. The $12B-valued company reached this position partly by acquisition, having bought non-human-identity vendor Oasis Security to assemble the agent security stack rather than build it.
