Authority, not just prompts.

AI agents do more than generate text. They read data, call tools, send messages, and change system state. Themis evaluates whether attacker-controlled inputs can push those actions beyond their intended authority. Themis applies that in two ways: test the agent before it ships, and govern its consequential actions while it runs.

Test the agent. Govern it at runtime.

AI Agent Security Assessment

See what an attacker can make your agent do.

Adversarial testing of the agent’s reachable capabilities: authority failures, sensitive data flows, approval failures, and the consequences that follow, with execution evidence for each finding.

Themis Agent Intelligence

Evaluate consequential actions before they execute.

Runtime authorization for the agents you already run. Themis evaluates each consequential action against delegated authority, data provenance, and runtime context, and returns ALLOW, ALERT, REQUIRE APPROVAL, or BLOCK to your existing execution layer. Start in Observe; enforce selectively.

About Agent Intelligence

Independent entry points: runtime security does not require a prior assessment. Only Continuous Agent Validation builds on assessment evidence.

Five ways an agent can act outside its authority.

Sensitive data flows

Can attacker-controlled input make the agent send sensitive data out?

  1. Customer record
  2. Report creation
  3. External message

Scope expansion

Can one record turn into access to many?

  1. Current customer
  2. Customer directory

Approval bypass

Can the agent act without the approval it should need?

Refund ≤ $500
Automatic
Refund > $500
Approval required

Unsafe action chains

Can individually allowed steps combine into an unsafe outcome?

  1. READ
  2. TRANSFORM
  3. SEND

Destination substitution

Can attacker input change the intended recipient or destination?

  1. Address on file
  2. Attacker-supplied address

How an assessment works, step by step →

Optional additional capacity.

Expert services are optional additional capacity for teams still designing a system, or with questions a standard assessment does not cover. Automated findings do not require a paid human-validation tier.

For an AI agent, four short questions get you a factual support determination before any scoping call. For web applications and APIs, request a scoped proof of concept.
