ISO 27001 nonconformities and corrective action

By Sam Rivera, Founder, SentinelPanda · June 19, 2026 · 1 min read · ISO 27001

A nonconformity is not failure — an audit with zero findings is more suspicious than one with a few. What matters is how you close them.

Minor vs major

Auditors classify findings. A minor nonconformity is an isolated lapse — one missed access review. A major is a significant or systemic failure — no risk assessment at all, or a control that is absent rather than imperfect. Majors block certification until resolved; minors are managed through corrective action with the certificate still attainable.

Findings are normal

A Stage 2 audit that finds nothing is rare and, frankly, a little suspect — it usually means a shallow audit. A handful of minor findings is the normal, healthy result. What the certification body actually judges is whether you respond to them properly, not whether they exist.

Corrective action fixes the cause

Clause 10 requires corrective action that addresses the root cause, not just the symptom. A late access review is not closed by doing that one review — it is closed by understanding why it slipped and changing the process so it does not recur. That root-cause discipline is what auditors look for.

Close the loop with records

For each nonconformity: record it, analyse the cause, define and implement the correction, and verify it worked — with dates. That record is the evidence that the management system self-corrects. SentinelPanda tracks findings to closure and keeps the corrective-action trail.
