Wytness — The Blackbox Recorder for AI Agents

Wytness is the managed compliance and audit layer for AI agents. Every action your agents take is signed with your key, every sensitive payload is sealed so we never see it, and the whole record is auditor-ready. Built on Microsoft's open-source Agent Governance Toolkit (AGT), Wytness is vendor-neutral and runs wherever your agents do.

Why teams running regulated AI agents choose Wytness:

• You hold the keys. Personally identifiable data is pseudonymised in your own environment with a key only you hold. Wytness stores evidence without ever seeing the secrets — true zero-knowledge.
• Non-repudiable evidence. Every event carries a per-event Ed25519 signature in a tamper-evident envelope. An agent owner attested to this exact action and cannot deny it later.
• Auditor-ready output. Evidence Packs map your agent activity to EU AI Act, SOC 2, and ISO 27001 controls — the deliverable your auditor actually expects.
• Your storage, or ours. On Business and above, bring your own storage — evidence lands in an Azure Blob container in your own tenancy, where you can apply your own immutability policy. AWS S3 is on the roadmap. Or let Wytness host it for you.
• Retention that matches your obligations. A live queryable dashboard window on every plan, and from Business upward a seven-year archive with signed handover on exit.
• Choose where your evidence lives. Data residency is available on Business and above — tell us the region you need and we provision into it.

Three surfaces, one platform:

• Ledger — the audit and evidence layer: per-event signing, customer-held PII keys, long-term retention, and Evidence Pack PDFs.
• Registry — the inventory and detection layer: a live dashboard of Events, Agents, Tools, Sessions and Permissions, with a seven-rule behavioural anomaly engine.
• Shield — the policy layer: author policies and run them in observe mode, with in-process enforcement available through the AGT library in your own runtime. Wytness-side enforce mode and human-in-the-loop approval routing arrive Q4 2026.

Built on Microsoft AGT. Wytness extends Microsoft's Agent Governance Toolkit — identity, delegation and a tamper-evident hash chain — with the non-repudiation and privacy layer regulated buyers need. Install the Wytness SDK (Python or TypeScript), and your existing AGT audit events flow straight into Wytness, signed and sealed.

Fully managed SaaS. Up and running in minutes. Cloud-hosted and regulator-ready.
