Integrating ISO 27701 Without Duplicating Governance

The mistake I see most often

Organisations that already have ISO 27001 in place frequently treat ISO 27701 as a separate project. That's expensive, and it's not what the standard is designed for.

ISO 27701 is an extension, not a parallel system

It's structured as additional guidance and controls layered directly onto ISO 27001's management system clauses, plus PIMS-specific controls for PII controllers and processors.

Where the real work is

The genuine lift is in mapping data flows precisely enough to know exactly where you're a controller versus a processor, for which categories of personal data, and under which legal basis.

A practical sequencing note

I generally recommend organisations complete at least one full ISO 27001 internal audit cycle before layering on ISO 27701.

“If a control cannot be evidenced, it does not exist.”
