Building an audit-ready evidence trail for software compliance

The teams that sail through audits aren't the ones with the thickest binder — they're the ones who can produce a current, coherent trail on demand. Compliance is less a document and more a habit of leaving evidence behind you as you work.

What a good trail contains

  • SBOMs for each release — what you shipped, when.
  • Scan results and their outcomes — what you found and what you did about it (including VEX "not affected" decisions).
  • Update records — proof you distributed fixes within your support commitment.
  • Readiness assessments against the requirements, with gaps and how they were closed.

Make it tamper-evident

An evidence log you could quietly rewrite isn't evidence. Integrity — being able to show the record wasn't altered after the fact — is what turns your trail from a claim into proof.

The goal isn't to survive one audit. It's to always be one query away from proving how you keep your product safe.

Keep it continuous

Evidence generated once a year decays. Wire it into your release process so the trail grows on its own, and the audit becomes a report you run rather than a project you dread.

A sealed, continuous Evidence Log is core to how Proofwright works.
