ISO 27001 vs SOC 2: where do IAM and access reviews fit?

TL;DR: ISO 27001 and SOC 2 both target security assurance, but they differ in scope, audit model, and how they support access governance, according to Zluri’s comparison. For identity teams, the practical question is which framework better aligns with your access review cadence, control evidence, and lifecycle discipline.

By the numbers:

• ISO 27001 outlines 114 security controls organized into 14 control sets.
• Only 44% of organisations have implemented any policies to manage their AI agents, despite 92% agreeing that governing AI agents is critical to enterprise security.
• 70% of organisations grant AI systems more access than they would give a human employee performing the exact same job.

Questions worth separating out

Q: How should organisations decide between ISO 27001 and SOC 2?

A: Choose based on where the assurance need sits.

Q: Why do access reviews matter in both ISO 27001 and SOC 2?

A: Access reviews matter because both frameworks depend on proof that permissions are appropriate and periodically validated.

Q: What do security teams get wrong about ISO 27001 and SOC 2?

A: Teams often treat the frameworks as interchangeable labels for compliance.

Practitioner guidance

• Align access evidence to the assurance model Map provisioning, certification, and revocation records to the framework the business is pursuing, then keep the evidence consistent across audit cycles and control owners.
• Separate entitlement control from certification Use one workflow to grant or remove access and another to review whether that access still has a business justification.
• Document supplier and contractor offboarding Include third-party access removal in the same lifecycle process used for employees so supplier relationships do not leave stale entitlements behind.
