Integrity fingerprint
A SHA-256 fingerprint is calculated on deposit: the slightest alteration to the document is immediately detectable.
Certyneo Vault
The digital safe with probative value
Keep your important documents — signed contracts, payslips, invoices — sealed, timestamped and immutable for their entire legal retention period. For individuals and businesses alike.
Much more than simple storage
Every document you deposit goes through a chain of evidence that complies with the NF Z42-020 standard.
RFC 3161 timestamping
An RFC 3161 timestamp token, issued by a third-party timestamping authority, attests to the date of deposit of each document.
Immutability (WORM)
Documents are locked in write-once mode: they cannot be modified or deleted before the end of their retention period.
Guaranteed retrieval
You can retrieve all your documents at any time, with no dependency and no vendor lock-in.
