Cryptographic Compliance
for AI Agents
Prove your AI agent is well-behaved — without revealing how it works. Zero-knowledge STARK proofs generated in 9ms.
How It Works
From individual observations to a tamper-proof compliance record — five steps, fully automated.
Observe
Collect behavioral metrics from your AI agent — quality scores, latency, safety checks, or any measurable signal.
Prove
Send observations to the SENTINEL API. A STARK proof is generated in 9ms attesting behavior stays within your defined limits.
Verify
Anyone can verify the proof — clients, auditors, regulators — without seeing the raw data. Zero-trust, tamper-proof.
Chain
Link proofs into a cryptographic chain. Each proof references the previous one, creating a verifiable behavioral timeline.
Register
Publish proofs to the on-chain registry. Immutable, publicly auditable, timestamped — your compliance record of truth.
Why SENTINEL
Purpose-built for AI agent compliance. Not another generic ZK platform.
Zero-Knowledge by Design
Your raw observations never leave the proof. Auditors verify compliance without seeing proprietary operational data. Designed for GDPR, CCPA, and DORA compliance by construction.
9ms Proof Generation
Fast enough for synchronous API calls. Generate proofs in real-time as part of your agent's workflow — no batch jobs, no waiting.
Proof Chaining
Link proofs into a cryptographic chain where each proof references the previous one. Build a verifiable behavioral timeline that auditors can walk from genesis to present.
Proof Registry
Publish proofs to a public, immutable registry at registry.starksentinel.com. Timestamped, queryable, and independently auditable — your compliance record of truth.
Proof Aggregation
Aggregate multiple proofs into a single Merkle commitment. Verify an entire chain of proofs in one call — efficient compliance at scale.
VBA Standard
The Verifiable Behavioral Attestation standard defines how proofs, chains, and registrations compose. An open specification for interoperable AI compliance.
Client-Side Verification
Ship our WASM verifier to your clients. They verify proofs locally in 158ms — no network calls, no trust in SENTINEL required.
MCP Native
Drop SENTINEL into any MCP-compatible AI agent framework. Six tools — prove, verify, chain, aggregate, verify-aggregate, and health. Five-minute integration.
Compliance Reports
Generate professional PDF attestation reports from any proof. File them with auditors, attach to contracts, share with partners.
Try It Live
Generate a real STARK proof right here. No sign-up, no API key needed.
Sends 8 sample behavioral observations to the live API and auto-verifies the result.
Built For
AI Agent Operators
Prove to your clients that your agent stays within behavioral bounds — response quality, latency, safety scores — without exposing operational data or proprietary algorithms.
Enterprise Compliance Teams
Get verifiable evidence that third-party AI agents are behaving as contracted. File cryptographic attestation reports with auditors for SOC 2, DORA, or internal audit.
