How to prepare for an ISO 27001 audit

Treat ISO as a working system (ISMS), not a binder. Focus on scope, risks, controls, and evidence.

When this is required

Enterprise sales, larger datasets, or procurement asks.

Preparation checklist

• Define scope (systems, locations, products).

• Risk assessment with treatment plan.

• Annex A control mapping (what you do, where it lives).

• Document control; training; internal audit; management review.

Step‑by‑step process

1. Scope & statement of applicability (SoA).

2. Risk assess: identify top risks; assign owners and mitigations.

3. Controls: connect real practices (MFA, backups, change control) to Annex A.

4. Evidence: gather logs, tickets, and reports.

5. Internal audit → management review.

6. Stage 1: fix gaps; schedule Stage 2.

Docs & approvals

Policy set, SoA, risk register, internal audit report, management review minutes.

Mitigations & follow‑up

Track corrective actions; close them before Stage 2.

Templates & tools

Your ticketing, identity, and logging stack are your evidence engines.
