In short

What is a Microsoft 365 security assessment?

A Microsoft 365 security assessment, sometimes called a Microsoft 365 security audit, is a fixed-scope review of how your Microsoft 365 environment is configured and where it is exposed. It produces a cyber security rating and a ranked list of fixes, so you know what to do first and what can wait. It is a fixed price of £999 and takes 4 to 6 weeks, with read-only access.

What's included

  • A cyber security rating for your Microsoft environment
  • Findings from threat and malware detection checks
  • Identity, email and device exposure explained in business terms
  • Fixes ranked by risk and effort
  • Useful preparation for Cyber Essentials or a cyber insurance renewal

Most security reviews produce a long list of findings. This one ends with a short list of decisions: what to fix first, what it costs, and what can wait.

Security audit or security assessment?

People search for a Microsoft 365 security audit, an Office 365 security review or a security health check. They usually mean the same thing: an independent look at how the tenant is set up and where it is exposed. We call it an assessment because it ends with a plan, not just a pass or fail.

What we look at

  • Identity: multi-factor authentication, Conditional Access, admin roles and accounts that should no longer exist
  • Email: phishing and spoofing protection, forwarding rules and mailbox access
  • Devices: which devices can reach company data and how they are managed
  • Data sharing: files and sites shared outside the business or more widely than intended
  • Threat detection: what Microsoft Defender is set to catch and what it is reporting

Each finding is explained in business terms, with the risk it creates and the effort needed to fix it.

Delivered remotely, across the UK and Europe

The assessment is carried out remotely with read-only access to your Microsoft 365 environment, so your location does not matter. Whether your business is in London, Kent, elsewhere in the UK or in Ireland or the rest of Europe, the process, the fixed price of £999 and the timescale of 4 to 6 weeks are the same. Read-only access means nothing in your setup is changed during the assessment.

What every assessment ends with

  • Your landscape, mapped across infrastructure, platform and software
  • Your current cost, layer by layer
  • A roadmap with risks, and savings ranges worth testing
  • A senior readout and a report you keep

Frequently asked questions

Is this the same as a penetration test?

No. It reviews the configuration and exposure of your Microsoft environment and ranks what to fix. It does not attempt to break in.

What does an assessment cost?

Each assessment is a fixed price of £999, agreed before we start. There is no hourly billing.

How long does an assessment take?

4 to 6 weeks. Your team's time is limited to a scoping conversation and giving us read-only access to the relevant environment.

Will you change anything in our systems?

No. Access is read-only during the assessment. We look before we touch, and any changes happen only if you later decide to act on the findings.

Do we keep the report?

Yes. The findings, cost view and roadmap are yours to use, whether you act on them with us, with another supplier or in-house.

Do you sell Microsoft licences?

We are an authorised Microsoft CSP partner. Every assessment is scoped and priced separately from any licence sale.
