Signed compliance evidence: why it beats a spreadsheet
When a customer reviews your security, the question is not only what you claim, but whether the claim can be trusted. Anyone can edit a spreadsheet after the fact. Cryptographically signed evidence cannot be changed unnoticed.
What signed evidence is
Each evidence document carries a digital signature (Ed25519) that ties the content to a point in time and an issuer. Change one letter and the signature breaks. That gives customers and auditors verifiable proof that the document is authentic and unaltered.
Why it shortens the deal
- Less back and forth: the buyer can verify instead of requesting clarifications.
- Higher credibility: a signed, dated document with named human sign-off carries more weight than a self-reported table.
- Audit-ready: the same evidence holds up for customer due diligence, for regulators, and for a future certification process.

Frequently asked questions
Do customers already require signed evidence? More and more ask for verifiability, even if few yet specify the exact technology. The advantage is that you are a step ahead.
Does it replace a certification? No, but it complements it and is reusable in a certification process.
