Detection, prevention and response for enterprise agents

Evoke Security is a detection, prevention and response platform for the AI agents enterprises have rolled out to their workforce, such as Claude, Codex and Copilot.

It gives security teams unified visibility across the agent platforms they actually run, answering two questions most teams cannot: what those agents are doing, and whether anyone would know if one went rogue or an employee used one to bypass a security control.

Its detection engine combines signatures, machine learning and small language models to judge what an agent is trying to do, not just what it touched — catching an employee routing around a control or an agent reaching for credentials it does not need. When something crosses the line, Evoke blocks the action, redirects the agent to a safer path or ends the session, and keeps a full audit trail so investigations take minutes instead of days.

Evoke Security was founded in 2025 by Jason Rebholz, a former CISO, and Jeffrey Chan, a former CTO, both of whom spent more than a decade in incident response.
