Standards comparison
Crossbearing See what carries over
Pick the standard you have and the one you want next. See, clause by clause and control by control, what you can reuse, what to extend and what is new — and whether you need to rewrite your policies.

How it works
-
At a glance, for any pair
What kind of thing each is, how it applies, how you show you meet it, and where — from MajorCyber™’s guide to each.
-
The management system, clause by clause
ISO management-system standards share a harmonised structure, so clauses 4 to 10 line up. Each clause of the standard you want is marked against the one you have.
-
Controls and documents
Every control of the standard you want, with the controls you already run that support it, and what to do with each document.
What the marks mean
- Reuse
- Use what you have: the same process or document, with its scope widened.
- Extend
- Keep what you have and add the new standard’s content.
- New
- Nothing you have covers it: new work.
- Keep separate
- Must stay distinct, even in an integrated system.
An educational comparison. A mapping shows where work you have already done supports a requirement; it never means the requirement is met, and your certification body decides what conforms. Clause and control numbers are cited; no standard’s text is reproduced.
