The number one question we hear from CISOs right now is: how do I secure AI agents I can't even see? Evoke is the answer." Andre Fuetsch, Managing Director, Crosspoint Capital. "The rise of agents has created an entirely new attack surface existing tools were never designed to address. Evoke's founding team has spent their careers on the front lines." George Barnes, President, Cyber Practice, Red Cell Partners, and former Deputy Director of the NSA.

Each action is judged against the agent's full trajectory: the current action, the session, activity across sessions, and handoffs between agents. Evoke assesses every action on four dimensions: - Mission: are the action and trajectory still aligned with the original task? Range: on-mission, drifting, deviating, off-mission. - Method: is the approach rational and proportionate, or does a safer path exist? Range: reasonable, debatable, aggressive, excessive. - Motive: what intent does the behavior imply? Range: good, uncertain, suspicious, malicious. - Magnitude: how much could the action change the risk or blast radius? Range: safe, sensitive, risky, dangerous. The combined assessment drives one of four responses: - Allow: the action proceeds. - Nudge: the agent is guided to a better path. - Alert: the security team is notified. - Block: the action or agent is stopped and a human has to act. Detection rules roll out per organization from shadow mode to alert to block, so teams tune a rule before enforcing it. Detection coverage maps to the OWASP Top 10 for Agentic Applications.

For Claude Enterprise, Evoke covers Claude chat, Claude Cowork, and Claude Code sessions through the Claude Compliance API. - Deployment takes minutes through existing MDM (Jamf, Microsoft Intune, Kandji, Group Policy) and API integrations, with no disruption to employee workflow and no professional services engagement. ## What the platform includes - Detection and response: monitors every prompt, tool call, and action across local, production, and SaaS agents; detects agent misuse and rogue agents; nudges, alerts, or blocks. - Investigation: a full forensic trail of agent and human actions with enterprise search, plus Slack and email alerting. - Inventory: a live inventory of agents, MCP servers, Agent Skills, tools, models, and permissions across the enterprise. - Posture: surfaces over-permissioned agents, toxic tool combinations, and malicious Agent Skills and MCP servers before they are exploited, with continuous scanning of MCP servers and Agent Skills. ## Frequently asked questions ### What does Evoke Security do? Evoke gives security teams detection, prevention, and response for the AI agents their employees use. It captures what agents do (prompts, tool calls, MCP servers, Agent Skills, sub-agents, and permission changes), detects when an agent is misused or goes rogue, blocks risky actions inline, and gives investigators a full forensic trail of agent and human activity. ### What does "EDR for AI agents" mean? Endpoint detection and response gave security teams visibility and control over processes on laptops and servers. Evoke applies the same detection and response discipline to AI agents. The unit of analysis is the agent's task and trajectory rather than a process, because agents reason, call tools, and move work between local, production, and SaaS environments. ### What is AIDR? At Evoke, AIDR stands for Agent Detection & Response: detecting, preventing, and responding to misuse and rogue behavior by AI agents. Other vendors use AIDR to mean AI Detection and Response, which usually centers on model inputs and outputs. Evoke's AIDR centers on the agent: its task, tool calls, MCP servers, Agent Skills, sub-agents, and the path it takes across a session. ### Why can't existing security tools catch rogue agents? Most detections evaluate one action at a time. An agent's web request can look harmless alone and still be the last step of an exfiltration chain. Evoke reads the full trajectory, so risk that builds across individually reasonable steps stays visible. ### How is Evoke different from an AI gateway, MCP gateway, or proxy? Gateways and proxies see the traffic that crosses them. For local agents, Evoke hooks into the agent runtime itself, so it also sees agents that shell out, local MCP servers, sub-agents, permission changes, and tool calls that never cross a network gateway. Because it sits in the runtime, Evoke can block an action and steer the agent to a safer path instead of only logging it. For production agents, Evoke's SDK and proxy API add the same agent-level context to traffic from custom agents. ### How is Evoke different from AI features in an existing EDR or XDR? Endpoint tools record that a process ran or opened a connection. Evoke records which task, reasoning step, and tool call caused it, and judges that action against the path the agent has taken so far. ### How is Evoke different from AI security posture management? Posture management finds risky configuration before an agent runs. Evoke includes inventory and posture, and its focus is runtime: detecting misuse and rogue behavior as it happens, preventing it, and investigating it. ### Which agents does Evoke support? Claude Code, Claude Cowork, Claude chat, Cursor, OpenAI Codex, GitHub Copilot CLI, and Google Antigravity on Mac and Windows endpoints; Amazon Bedrock, GitHub, and Google Cloud for production agents; and Anthropic, OpenAI, and Google (Gemini) SaaS agents. Claude Enterprise coverage runs through the Claude Compliance API. ### How is Evoke deployed? The endpoint sensor deploys in minutes through existing MDM tools (Jamf, Microsoft Intune, Kandji, Group Policy). SaaS and production coverage connects through API integrations. No professional services engagement is required. ### Who founded Evoke and who invested? Jason Rebholz (CEO, former CISO) and Jeff Chan (CTO, former CTO and security engineering leader) founded Evoke after years in incident response supporting the Fortune 1000. Crosspoint Capital led the $4M pre-seed round, with participation from Red Cell Partners. ### Is Evoke SOC 2 compliant?
