What this page covers
cloud and data centres teams need proof that decisions, controls, changes and incidents happened under the right policy and system version. This page maps the evidence Attesto can seal before an audit or customer review.
Legal timing
NIS2 was due for national transposition by 17 October 2024. National implementation differs by Member State, but incident and control evidence should be retained before an authority or customer asks for it.
This page is implementation guidance for evidence planning, not legal advice.

Where Attesto fits
Sector GRC tools help cloud and data centres teams manage obligations. Attesto adds a cryptographic evidence layer for selected logs, approvals, model changes and incident packets.
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 AI Act evidence for cloud and data centres fit in the compliance stack?
Sector GRC tools help cloud and data centres teams manage obligations. Attesto adds a cryptographic evidence layer for selected logs, approvals, model changes and incident packets.
