The CISO Decision Brief

Guidance · Situation

The auditor arrives in six weeks

A Stage 1 or Stage 2 ISO 27001 audit is in the diary.

Why this moment is hard

Six weeks is enough to close the gaps an auditor reliably finds, and not enough to build what was never there. The risk is spending the time polishing documents while the scope, the exclusions or the people interviews let you down.

5 Guidance questions3 pack documents1 toolAbout 3 h 40 min of reading in all

This is a reading path, not a checklist. Nothing is ticked off or saved, and you can start at any step.

First, the decisions

  1. Guidance · Regulation, audit and certification

    When are we ready for the Stage 1 audit?

    5 decision points · about 10 min to read

    Why here First decide honestly whether you are ready, and what would make you move the date.

  2. Guidance · Regulation, audit and certification

    How do we justify excluding an Annex A control?

    5 decision points · about 10 min to read

    Why here Exclusions are the first thing a Stage 1 auditor reads in the Statement of Applicability.

  3. Guidance · Regulation, audit and certification

    How do we run an internal audit when we are small?

    7 decision points · about 10 min to read

    Why here An internal audit has to have happened before certification, even a small one.

  4. Guidance · Regulation, audit and certification

    How do we prepare our people for auditor interviews?

    5 decision points · about 10 min to read

    Why here People are interviewed, not only documents; prepare them without scripting them.

  5. Guidance · Regulation, audit and certification

    If the auditor raises a major nonconformity, then what?

    7 decision points · about 10 min to read

    Why here Know in advance what you will do if a major nonconformity is raised.

If your start looks different

Reading times are estimates: the words on each question's flow or document's preview at 220 words a minute, rounded up to the next five minutes. A tool shows its own time.
