Microsoft 365 Security Review
Independent review of identity, endpoint, mail, collaboration and audit controls, ending with a prioritised remediation backlog.
The Microsoft 365 Security Review is a structured, independent read of the tenant controls that matter most: identity, endpoint, mail, collaboration and the audit evidence that proves changes actually happened. The output is a prioritised backlog, not a generic checklist.
How it runs
Tenant evidence first, fixes second.
The review starts by confirming admin access, tenant size, current suppliers, licensing and the control areas in scope. Elevated permissions are time-bound and scoped. Nothing changes without an explicit decision.
Findings are grouped by risk to operations, not by portal menu. Identity and endpoint gaps come before mail and collaboration settings because access failures are the faster escalation path. The backlog gives each finding a business owner and a sequenced remediation step.
Best for
- SMEs that know their Microsoft 365 tenant has drifted.
- Teams that need a fast risk picture before audit, renewal or board review.
- Internal IT teams that want an outside control review without replacing day-to-day support.
Commercial details
- Commercial model
- Defined review scope with fee agreed before access.
- Typical budget
- £1,500 to £2,500
- Typical timeframe
- Usually 5 working days after access and context are ready.
Signs this is the right fit
Use these signals to check whether an independent Microsoft 365 security review fits the current problem. They narrow the scope before the conversation starts.
- Admin roles have grown without a clear owner or review rhythm.
- MFA, Conditional Access and break-glass access exist but nobody trusts the exceptions.
- Security settings are being discussed at board, audit or renewal time without a current evidence pack.
The output explains the risk order, what was reviewed, what changed, what still needs approval and who should own recurring checks.
The first week is usually evidence-led: confirm admin access, export the high-risk settings, compare them with expected control ownership, then separate urgent exposure from tidy-up work. That stops the review becoming a tour of every portal blade and keeps decisions tied to business risk.
