| Aspect | SOC 2 | ISO 27001 |
|---|---|---|
| Access control | CC6.x, CC7.x expectations | Annex A.5, A.8, A.9 controls |
| Change management | CC8.x change, deployment, and integrity | Annex A.12, A.14 for change and development |
| Logging/monitoring | CC7.x monitoring and alerting | Annex A.5, A.8, A.13 logging and monitoring expectations |
| Availability | A1 availability controls | Annex A.5, A.17 business continuity and resilience |
| Vendor management | CC9.x third-party risk | Annex A.5, A.15 supplier relationships |
Decision guide
- •Maintain one control library mapped to both frameworks to reduce evidence duplication.
- •Collect evidence once and tag it to SOC 2 TSC and ISO Annex A controls.
- •Align cadence: access reviews, logging checks, and change approvals serve both frameworks.
FAQ
Do we need separate evidence for each?
No—tag evidence to both control sets. Ensure narratives satisfy both auditors and certification bodies.
How do we document mappings?
Create a simple matrix linking SOC 2 criteria to ISO Annex A controls with evidence references.
What about risk management?
ISO requires formal risk management; SOC 2 benefits from it. Keep a shared risk register and treatment plans.
How often should we refresh mappings?
At least annually or when controls change. Update when new systems or regions are added.
Can one pentest serve both?
Yes if scoped appropriately. Ensure the report covers in-scope systems and is recent enough for both audiences.
How do we onboard new control owners?
Provide mapped controls with evidence examples so they understand how work supports both frameworks.
