ISO/IEC 27001 is the most recognised standard for information security management. If your organization runs on Microsoft 365, many of the technical controls auditors look for are already available in your tenant. The challenge is configuring them, documenting them and proving they work.
This guide maps ISO 27001:2022 Annex A controls to Microsoft 365 features and shows how to collect audit-ready evidence.
ISO 27001:2022 at a Glance
The standard has two parts. Clauses 4 to 10 define the ISMS: scope, risk assessment, leadership, documentation, audits and improvement. Annex A lists 93 controls in four themes.
| Annex A theme | Number of controls | Microsoft 365 relevance |
|---|---|---|
| Organizational | 37 | Policies, supplier and cloud security, incident management |
| People | 8 | Training, awareness, remote working |
| Physical | 14 | Mostly covered by Microsoft for cloud, your offices for the rest |
| Technological | 34 | Heavily supported by Microsoft 365 security tools |
Mapping Key Annex A Controls to Microsoft 365
| Control area | Microsoft 365 capability |
|---|---|
| Access control and authentication | Entra ID, MFA, Conditional Access |
| Privileged access | Privileged Identity Management |
| Endpoint devices | Intune compliance, BitLocker, Defender for Endpoint |
| Malware protection | Defender XDR and Defender for Office 365 |
| Information classification and labelling | Purview sensitivity labels |
| Data leakage prevention | Purview DLP |
| Logging and monitoring | Unified audit log, Microsoft Sentinel |
| Configuration management | Intune baselines, Secure Score |
| Information deletion | Retention and deletion policies |
| Backup | Microsoft 365 and Azure backup |
For identity controls, see Conditional Access best practices. For monitoring, read What is Microsoft Sentinel.
Using Compliance Manager and Secure Score as Evidence
Microsoft Purview Compliance Manager includes an ISO 27001 assessment template that tracks improvement actions and stores evidence. Microsoft Secure Score reports show configuration progress over time. Export both monthly and file them in your ISMS.
A 7-Step Path to ISO 27001 With Microsoft 365
- Define the ISMS scope and boundaries.
- Run a gap analysis against clauses and Annex A.
- Complete a risk assessment and Statement of Applicability.
- Configure Microsoft 365 controls in priority order.
- Write short, usable policies linked to each control.
- Run an internal audit and management review.
- Book the certification audit with an accredited body.
A Zero Trust roadmap for Microsoft 365 fits naturally into step 4.
Common Mistakes
- Treating Microsoft’s own ISO certificate as yours.
- Buying policy templates nobody follows.
- Configuring controls without keeping evidence.
- Ignoring suppliers and cloud apps outside Microsoft 365.
One Control Set, Several Frameworks
ISO 27001 controls overlap with UAE PDPL and Saudi NCA ECC. Build once, map many. Our UAE PDPL compliance checklist shows the overlap for data protection.

Frequently Asked Questions
Can Microsoft 365 help with ISO 27001 certification?
Yes. Microsoft 365 provides many technical controls that support ISO 27001 Annex A, such as access control, logging, encryption and device management. You still need an ISMS with policies, risk assessment and audits.
Is Microsoft 365 itself ISO 27001 certified?
Microsoft’s cloud services hold ISO/IEC 27001 certification. That covers Microsoft’s side of the service, not your organization’s own ISMS or configuration.
How many controls are in ISO 27001:2022 Annex A?
Annex A of ISO/IEC 27001:2022 contains 93 controls grouped into four themes: organizational, people, physical and technological.
Which Microsoft 365 tools matter most for ISO 27001?
Entra ID, Intune, Defender XDR, Microsoft Purview and Microsoft Sentinel cover most technological controls. Compliance Manager helps track control status and evidence.
Do we need Microsoft 365 E5 for ISO 27001?
No. Many organizations certify on Business Premium or E3. E5 makes some controls easier, such as advanced threat detection and auditing.
How long does ISO 27001 implementation take?
Most organizations need six to twelve months from gap analysis to certification audit, depending on scope and maturity.
Does ISO 27001 help with UAE and Saudi regulations?
Yes. Many ISO 27001 controls overlap with UAE IA standards, UAE PDPL and Saudi NCA ECC, so one control set can support several frameworks.
