Microsoft 365 security for UK small and regulated businesses
Most small businesses run on Microsoft 365, and most of the security they pay for is switched off or half set up. We test it, fix what fails and keep it right, at a fixed price, done by the engineers you talk to.

Questions
Where should a small business start with Microsoft 365 security?
With the controls that stop the most common attacks: multi-factor authentication on every account, legacy sign-in blocked, separate admin accounts, email authentication and only managed devices allowed. The free security check covers twelve of them; the Microsoft 365 MOT tests and fixes them in your tenant.
What's the difference between the MOT and the regulated-firm uplift?
The MOT is for small businesses generally. The uplift is built for law firms, IFAs and mortgage brokers, with the controls and evidence their regulators and clients expect. Both start from £1,800 for a typical 10-user organisation.
