What this page covers
Post-market monitoring requires operational memory. Attesto keeps monitoring records connected to proof packages.
Legal timing
The AI Act entered into force on 1 August 2024. The Commission describes 2 August 2026 as the general application date, while the AI Omnibus political agreement moves many high-risk areas to 2 December 2027 and product-integrated systems to 2 August 2028. The preparation work still has to start now because evidence cannot be rebuilt reliably after deployment.
This page is implementation guidance for evidence planning, not legal advice.

Where Attesto fits
Monitoring tools show what they see now. Attesto helps prove what they saw then.
FAQ
How is this different from a normal log?
A normal log asks an auditor to trust the system that produced it. Attesto records hashes, signatures, Merkle proofs and verifier receipts so selected evidence can be checked independently.
Does Attesto need to expose raw sensitive data?
No. Raw records can remain encrypted or customer-controlled while proof material is shared for verification.
Where does Post-market monitoring evidence fit in the compliance stack?
Monitoring tools show what they see now. Attesto helps prove what they saw then.
