Status and what to ask come from Assurix. Everything else is what each provider lists on its profile, and Assurix hasn’t checked it.

How this list is made

Listings come from the Assurix Trustmark Directory, as at 14/11/2026. Assurix sets each provider’s status. Towns, sectors, certificates, founding year and staff numbers are what the provider lists. Providers working with Assurix pay a subscription. None of them can change a result, and an Assurix assessor signs off every Trustmark.

Grouped by status, in alphabetical order within each, so every Assurix Trusted MSP is shown equally. Reviews and payments play no part in the order. Assurix Trusted and On the Journey providers are Assurix customers whose status Assurix checks, which is why they come first. Committed providers have signed up with a start date booked.

Assurix Trusted MSP
Independently assessed by Assurix on 59 controls across security and service. It passes all of them, with live evidence from its own tools. A failure left unfixed for 30 days suspends the Trustmark publicly.

Before you sign with any provider, read the NCSC’s guidance on choosing a managed service provider, and check a Cyber Essentials certificate on the IASME certificate search.
