ISO 27001 vs PCI DSS: Overlap and Differences

Overlap

Policies, IAM, crypto, vuln management, and IR programmes often feed both.

Differences

• PCI scopes the CDE; ISO scopes the ISMS boundaries you define
• PCI has SAQ/RoC validation; ISO has accredited certification
• PCI is more prescriptive on CHD protections

Sequencing

Many merchants run both — map controls once with dual tags.
