Runtime enforcement infrastructure for autonomous AI agents

Kevros sits between intent and execution. Every action requires a signed release token. No token, no execution.

How It Works

A three-step process: request, decision, proof. Each decision is cryptographically signed and independently verifiable.

1
Agent Requests Permission
Agent submits action_type, payload, and context. Kevros evaluates against policy.
2
Kevros Evaluates and Decides
Policy evaluation returns ALLOW, CLAMP, or DENY. Decision is cryptographically signed.
3
Evidence Recorded
Decision hash-chained, tamper-evident, independently auditable. No action executes without valid token.

Three Decisions

Every action evaluation results in a cryptographic proof of authorization.

ALLOW

Action proceeds. Release token issued as cryptographic proof of authorization. Token bound to agent identity and policy state.

CLAMP

Action adjusted to safe bounds. Modified action parameters returned in response. Original action blocked. Safe variant executed with proof.

DENY

Action rejected. No release token. Denial recorded with reason. Agent receives cryptographic proof that action was blocked.

Cryptographic Enforcement, Not Monitoring

Traditional security monitors what happened after the fact. Kevros prevents unauthorized actions before they execute.

Fail-closed state machine: If the token is missing or invalid, the action is blocked. No exceptions. No override. No fallback to "log and hope."

ML-DSA-87 post-quantum signatures: FIPS 204 compliant. Resistant to quantum computing attacks. Every decision cryptographically signed and independently verifiable.

Hash-chained ledger: Evidence chain links identity, authorization policy, decision timestamp, and outcome. Auditors verify the chain without trusting Kevros.

Evidence Chain Entry (ML-DSA-87)
agent_id: "claude-opus-4.6"
action: "database_delete"
policy_hash: "f8a3c2e1..."
decision: APPROVED
signature: "0xf2d8a94e..."
timestamp: "2026-04-03T14:22:19Z"
prev_hash: "a7b4e291..."
