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.

ISO 27001 and SOC 2 expose governance maturity, not just compliance posture. The comparison is valuable because it shows whether an organisation can sustain control discipline under scrutiny, not whether it can pass a single audit. ISO 27001 pushes toward system-wide governance, while SOC 2 narrows the question to operating effectiveness over time. Practitioners should treat the choice as a test of evidence quality, control ownership, and lifecycle rigor.
A few things that frame the scale:
- 67% of organisations still rely heavily on static credentials despite the risks they pose to agentic AI deployments, according to The 2026 Infrastructure Identity Survey.
- Only 7% of security leaders admit they do not know how often their AI systems are making autonomous changes to infrastructure, which shows how quickly visibility can erode once identity behaviour becomes runtime-driven.
A question worth separating out:
Q: Who is accountable when access certification fails an audit?
A: Accountability usually sits with the control owner, not the auditor. IAM, IGA, and PAM teams need named ownership for entitlement decisions, review completion, and remediation closure. If certification fails, the organisation should trace the gap to the process owner, the approver, and the evidence holder, not to the framework itself.
