Audit readiness checklist: how to walk into an audit with evidence already in place

Most audit stress comes from collecting evidence after the audit is announced. A checklist for being ready all year, for ISO 27001, SOC 2 or a regulatory IS audit.

Key takeaways

  • Most audit stress comes from collecting evidence after the audit is announced.
  • Status should come from completed work and evidence, not from a self-declared tick.
  • Evidence must cover the whole audit period, and you should be able to show it has not been altered.
  • One body of evidence, mapped once, can answer several audits.

Audit preparation often starts the day the audit is announced. Someone makes a list of requirements, someone else hunts for screenshots, and the team spends the following weeks rebuilding what happened over the year.

The audit does not need to start from a blank page. If the work is recorded as it is done, the evidence is already there.

Why audits hurt

PainWhat causes it
Evidence is hard to findIt was collected after the fact, and is easier to get wrong or leave incomplete
Status is disputedA control was marked done because someone said so, and the auditor asks for proof
Questions go unansweredOwnership is vague, so no one knows who answers a given question
The same finding appears twiceObservations from the last audit are still open

Tip. Aim for the evidence to build up as the work is done. That is what turns audit preparation from months to weeks.

One body of evidence, many audits

If you run more than one framework, the same evidence often answers several requests. Mapping it once, rather than collecting it again for each audit, removes much of the repeat work. The cross-framework mapping page shows how.

How Netra approaches it

Netra connects tasks, policies, risks, evidence and audits, so control status is derived from the work that was completed. The Audit Centre holds the audit plan, requests, findings and follow-up in one place, and evidence is tamper-evident, so it can be shown to be unaltered.

This article is for general information. Your auditor or regulator decides what is sufficient for your scope.

Frequently asked questions

Why does audit preparation take so long?

Most of the stress comes from collecting evidence after the audit is announced, instead of keeping it ready through the year.

Can control status be self-declared?

Status should come from completed work and evidence, not from a self-declared tick.

Can one set of evidence serve several audits?

Yes. One body of evidence, mapped once, can answer several audits, as long as it covers the whole audit period and can be shown not to have been altered.

The audit does not start from a blank page

Audit plan, requests, findings and follow-up in one place, with evidence that can be shown to be unaltered.
