How it works
-
Submit existing artifacts
Upload tickets, logs, approvals, change records, or related evidence through the browser.
-
Receive PASS or FAIL
AttestLayer evaluates the submission deterministically. On PASS, the evidence is bound into a signed, verifiable record.
-
Use the output where review happens
Forward the proof kit for approval, audit follow-up, dispute defense, partner review, or downstream verification.
Who it's for
Operators
Turn existing change evidence into a cleaner approval package without changing how your team works.
Compliance and risk
Get consistent, reviewable, defensible proof output without adding a new system-level vendor dependency.
Technical evaluators
Work from existing artifacts with signed proof outputs that can be independently verified.
Executive approvers
Improve approval quality with a low-friction, no-install path instead of a long software rollout.
Stronger than screenshots and ad hoc approvals
Most teams have evidence, but not in a form that is clean, consistent, easy to forward, or easy to defend later.
Typical current process
- Screenshots and exports assembled manually
- Approval context scattered across tools
- Hard to forward cleanly
- Weak consistency across teams
- Difficult to verify later

- Clear record of what was submitted
- Review-ready forwardable package
- Repeatable handling across workflows
