What this page covers
Incident evidence needs to survive urgency, handovers and later scrutiny. Attesto creates a verifiable timeline.
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
Attesto adds proof to existing security operations instead of asking teams to move all incident data into another tool.
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 NIS2 incident evidence fit in the compliance stack?
Attesto adds proof to existing security operations instead of asking teams to move all incident data into another tool.
