1. The core difference

ISO 27001 is a certifiable management system (a certificate). SOC 2 is an attestation report with an auditor’s opinion (a report you share).

2. Geography and buyers

SOC 2 is favoured by US buyers.
ISO 27001 is globally recognised.
Enterprise procurement may ask for either or both.

3. Effort overlap

The underlying controls overlap heavily, so doing one makes the other far faster. Start with the one your customers ask for.
