Autonomous red teaming for AI agents and applications.

Themis maps your attack surface, tests real attack paths, and validates vulnerabilities across AI agents, web applications, and APIs. Every finding comes with reproducible evidence.

Test before deployment. Protect at runtime.

Themis Agent Intelligence

Evaluate consequential agent actions before they execute.

Runtime authorization for the agents you already run: ALLOW, ALERT, REQUIRE APPROVAL, or BLOCK, decided before the action executes.

Five ways agents can cross boundaries.

How an assessment works: Connect → Discover → Confirm → Test → Report. Themis generates the initial capability and authority model. Your team confirms it.

Safe testing: sensitive actions can be intercepted, staging and test environments are supported, and production access is not required for a standard assessment.

Real reports generated from the Themis reference-agent assessment pipeline.

The Themis assessment engine has been evaluated against AgentDojo, AgentHazard, and a live MCP-based AI agent.

Real-world researchTested beyond benchmarks.Themis also evaluates widely adopted open-source AI infrastructure. Our research has identified security failures in agent and AI platforms used by thousands of developers.Responsible disclosure is ongoing for several findings.View security research
