Verisum provides organisations with tools to govern AI decisions, manage accountability and produce cryptographic proof. Its web and API service is organised around Govern, Monitor and Prove. Govern includes AI system and vendor registers, policy generation, shadow-AI tracking, model registries, regulatory feeds and compliance frameworks. Monitor covers drift, incidents, escalation workflows, runtime signals, staff declarations and team management. Prove includes decision ledgers, attestations, approvals, incident locks, provenance graphs, Trust Exchange, public verification and on-chain anchoring. The HAPP Protocol provides REST APIs for approvals, attestations, provenance, exchanges, incident locks and public verification. Verify can anchor attestations, incident locks and provenance records to EVM-compatible chains including Ethereum, Polygon and Arbitrum. Verisum states that data is encrypted in transit with TLS 1.2 or above and at rest with AES-256 through its managed database provider. Explorer is free forever; Core costs £129/month or £1,238/year, and Assure costs £499/month or £4,790/year. Verify has custom pricing. The DPA says the service is not designed for UK GDPR special category data, which customers must not submit.
