Free Microsoft 365 Security Audit — Check Your Posture & Costs in 3 Minutes
A free Microsoft 365 security audit you can run yourself, right now, without a sales call or handing anyone access to your tenant. In three minutes you’ll see how your security posture scores against the standards regulators and insurers expect — and how much Microsoft 365 licensing spend you could be reclaiming. Everything runs in your browser, so nothing you enter is ever uploaded, stored, or sent to us.
Most regulated firms are quietly doing two opposite things at once: overpaying for Microsoft 365 and under-protecting the licences they already have. This check surfaces both.
Is your Microsoft 365 secure — and are you overpaying?
See your security posture score and the licence spend you could reclaim, framed against your regulator. No sign-up, no sales call — and everything runs in your browser.
What this Microsoft 365 audit checks
The assessment looks at the controls that matter most when a regulator, auditor or cyber-insurer comes asking — and at the licensing decisions that quietly drain budget:
- Identity and access: multi-factor authentication coverage, admin protection, legacy authentication, and Conditional Access.
- Threat protection: Defender for Office 365, Safe Links and Safe Attachments.
- Data and resilience: Data Loss Prevention, audit logging and retention, and whether you hold an independent backup of your Microsoft 365 data.
- Licensing and cost: unused or unassigned seats, over-provisioned users (for example, E5 licences where E3 would do), and tiers that could be consolidated.
You answer a short set of questions, and the tool scores each area and shows you where the gaps are.
Why these gaps usually go unnoticed
The controls almost always exist inside Microsoft 365 — the problem is that nobody has checked whether they are switched on and configured the way they should be. A licence gets assigned to someone who later leaves. A user is put on the top tier “to be safe” and never moved down. MFA is enabled for most people but not enforced for everyone. None of it shows up until an incident, an audit, or an insurance renewal forces the question. A regular Microsoft 365 security audit is how you catch these before they cost you.

Your data never leaves your browser
This is the part we care about most. The entire Microsoft 365 assessment runs locally in your web browser. Nothing you type is transmitted to Innoligo or to any third party, nothing is stored, and we never ask for access to your tenant. For a regulated firm that is rightly cautious about who touches its systems, that means you can get real insight with zero exposure.
Built for regulated UK firms
Innoligo specialises in making high-stakes technology safe for regulated sectors. Every finding in this audit is framed against the expectations that apply to you — the FCA and DORA for financial services, the SRA for law firms, NHS DSPT for healthcare, and Cyber Essentials more broadly. It’s the same regulatory lens we bring to a full engagement, in a form you can try in minutes.
From self-check to verified audit
This tool gives you an honest, indicative picture — but it is a self-assessment, not a substitute for a verified audit. A full Innoligo Microsoft 365 security audit connects securely to your tenant to confirm the figures, surface what self-assessment can’t see, and deliver a board-ready remediation plan mapped to your regulator. If your results show gaps worth closing, that’s the natural next step.
Run the free check above, then book your verified audit when you’re ready.
Frequently asked questions
Is the Microsoft 365 security audit really free? Yes. The self-assessment tool is completely free, with no sign-up and no obligation. You only pay if you choose to commission a full verified audit afterwards.
Does my data leave my computer? No. The tool runs entirely in your browser. Nothing you enter is uploaded, stored, or sent to Innoligo or anyone else.
How long does it take? About three minutes. You answer a short set of questions about your licensing and security setup and get your results on the spot.
What’s the difference between this and a verified audit? This is an indicative self-assessment based on your own answers. A verified audit connects securely to your Microsoft 365 tenant to confirm the findings, go deeper, and produce a prioritised remediation plan and board-ready report.
Will it tell me if I’m compliant with the FCA, SRA or NHS rules? It highlights where your setup may fall short of common regulatory expectations and maps each finding to the relevant framework. It’s a starting point for a conversation, not a formal statement of compliance.
How much could I save on Microsoft 365 licensing? It varies by organisation, but unused seats and over-provisioned users are common and often add up to thousands of pounds a year. The tool gives you an indicative estimate based on the figures you enter.
Results are indicative and generated from self-reported inputs. They do not constitute a verified security or licensing audit, regulatory advice, or assurance of compliance. Microsoft 365 is a trademark of Microsoft Corporation; Innoligo is an independent partner.
It’s an indicative self-check, not a substitute for a verified audit — but in three minutes it’ll tell you whether you’ve got a problem worth a conversation.
If you’re in compliance or IT, I’d genuinely value your feedback on what to add.
