Microsoft 365 Security Audit

Microsoft 365 security assurance for complex organisations

Independent review of identity, access, tenant configuration and security controls, with risk-prioritised findings and practical remediation guidance.

Review the controls that shape Microsoft 365 risk

Entra ID & identity

Review identity configuration, authentication, administrator roles and the controls protecting access to the tenant.

Conditional Access & privileged access

Assess how access decisions, MFA requirements and privileged activity are controlled across users, devices and administration.

Exchange, SharePoint, OneDrive & Teams

Review important service configuration, collaboration controls, sharing behaviour and security settings across the core Microsoft 365 workloads.

External sharing & data protection

Identify configuration that can expose information through external collaboration, guest access or inappropriate sharing.

Logging, monitoring & security settings

Review relevant logging, monitoring and tenant-level security configuration so gaps are visible and actionable.

Prioritised remediation

Receive clear findings, management context and practical technical recommendations that can support wider assurance objectives such as Cyber Essentials Plus and ISO/IEC 27001.

A security assurance review, not a configuration dump

When a review is useful

A Microsoft 365 security review is particularly useful when a tenant has evolved over time, undergone major change, supports complex remote or hybrid working, uses extensive external collaboration, or needs independent evidence before a wider assurance programme.

It can also help establish a clearer baseline before Cyber Essentials Plus, ISO/IEC 27001 implementation or an internal security-improvement programme.

What the organisation receives

The engagement produces an agreed review scope, a concise management view of material risk, prioritised technical findings and practical remediation actions. The objective is to make important weaknesses understandable and actionable rather than generate a long list of settings without context.

A follow-up discussion can help technical and assurance teams understand priorities, dependencies and sensible next steps.
