IT providers for UK law firms

There are 340 IT providers serving Legal clients listed in the Assurix directory, including 9 with verified Assurix trustmarks.

Last updated: 7 October 2026

If you run or manage a law firm, your IT provider sits close to your case files, your client money and your email. When something slips with any of those, the work stops and clients notice.

This page lists providers who work with legal firms. Providers holding the Assurix Trusted MSP badge are shown first, and any working toward it appear as On the Journey. The rest are listed as not yet Assurix-verified, which says nothing bad about them. Many are strong providers who simply haven't been through the assessment.

Below you'll find what a good provider should be able to show a law firm, the questions worth asking before you sign, and how independent verification fits alongside the standards your insurer and clients already care about.

What to look for in a provider for a law firm

A good IT provider for a law firm does more than fix laptops. Here's what they should be able to show you, before and after you sign.

A grip on payment fraud risk
Conveyancing means moving large sums of client money, which is exactly what payment redirection fraud targets. A good provider should be able to explain how they help protect email and payment instructions from interception. Ask what would happen if a false 'change of bank details' email reached your team.
Tight control over client files
Your firm holds privileged and confidential information that sits under UK GDPR. A provider should be able to show who can access what, and how that access is logged and reviewed. Least-privilege access is a fair thing to expect.
A real plan for keeping work running
If systems go down mid-transaction or mid-trial prep, clients feel it fast. Ask how the provider backs up your case and matter data, how quickly it can be restored, and when they last tested a recovery. Continuity of case work is the thing to protect.
Support with SRA incident reporting
The SRA expects firms to report serious cyber incidents. When one happens, your provider is part of spotting it and helping you respond in time. A provider that understands this obligation is worth more than one that treats an incident as purely technical.
Evidence you can share upward
Insurers and clients increasingly ask about your supply chain security, including your IT provider. Look for a provider that can give you independent evidence of its controls, so you can answer those questions with proof. Continuous, independent verification is stronger than a one-off assurance.

Questions to ask an IT provider

You don't need to be technical to ask these. Good providers welcome them.

  1. Can you show how you'd keep our case management system and email running if your own systems were hit? Continuity of case work is what clients feel first when something breaks.
  2. How do you protect client money transfers and conveyancing payments from email interception? Payment redirection fraud targets exactly these large, time-sensitive transfers.
  3. Who on your side can access our privileged client files, and how is that logged? Confidential and privileged information sits under UK GDPR and the duty of confidence you owe clients.
  4. How would you support us in reporting a serious cyber incident to the SRA? The SRA expects firms to report serious incidents, and your provider is part of that response.
  5. What can you give us to answer our insurer's supply chain security questions? Professional indemnity insurers increasingly ask about the firm's IT provider.
  6. Do you hold any independent security verification, and can you evidence it? Independent proof carries more weight than a provider describing its own controls.

The compliance picture for law firms

Law firms in England and Wales are regulated by the Solicitors Regulation Authority, which expects firms to report serious cyber incidents. When an incident hits, your IT provider is part of how quickly you can respond and report.

Two Law Society standards, Lexcel and the Conveyancing Quality Scheme, both touch how a firm manages information, and your systems sit underneath that. Conveyancing adds its own pressure. Firms move large sums of client money, which makes email interception and payment redirection a well-known risk in the sector.

Firms also hold privileged and confidential client information, which is subject to UK GDPR. And there's growing outside interest in how firms protect it. Professional indemnity insurers and clients increasingly ask firms about their supply chain security, including the IT provider they rely on. That makes your provider's security part of the story you tell, and being able to evidence it is where independent verification helps.

How the Assurix Trustmark helps a law firm

The Assurix Trustmark gives a law firm a shorter way to check an IT provider. A provider carrying the Trusted MSP badge has passed all 59 controls in the Assurix assessment, aligned to the NCSC Cyber Assessment Framework v4. Assurix monitors continuously and reassesses every year. If a control fails, the provider has 30 days to fix it, or the badge is publicly suspended and disappears from the listing. When your insurer asks about your supply chain, that's evidence you can hand over.

Frequently asked questions

What does 'Assurix Verified' mean for a law firm choosing an IT provider?

Assurix is an independent trustmark for UK IT providers, built on the idea of proof, not promises. A provider showing the Trusted MSP badge has passed all 59 controls in the Assurix assessment, aligned to the NCSC Cyber Assessment Framework. There are no partial passes. Assurix monitors continuously and reassesses every year, so the badge reflects current standing rather than a single moment. If a control fails, the provider gets 30 days to fix it. If it isn't fixed, the badge is publicly suspended and disappears from the listing.

What's the difference between a Trusted MSP and an 'On the Journey' provider?

A Trusted MSP has passed all 59 controls. 'On the Journey' means a provider is working toward the Trustmark and hasn't passed yet. That status is time-limited to six months, so it shows genuine intent without being treated as a result. When you're choosing for a law firm, it's fair to see an On the Journey provider as one that's actively working on its security, while a Trusted MSP has already met the full bar.

Is a provider that's 'not yet Assurix-verified' a bad choice for my firm?

No. A provider listed as not yet Assurix-verified simply hasn't been through the assessment. Many are excellent providers with long records serving law firms, and some hold their own certifications. The status is neutral. It's a prompt to ask the questions on this page and look at the evidence a provider can show you, not a signal that a firm is unsafe or a poor choice.

Does the Assurix Trustmark replace Cyber Essentials or ISO 27001?

No. Assurix is a trustmark, and it doesn't give a provider Cyber Essentials, ISO 27001 or any other certification. Those are separate schemes, and your insurer or clients may still ask a provider about them directly. What the Assurix Trustmark adds is independent, continuous verification against the NCSC Cyber Assessment Framework. You can hold both. A provider might carry its own certifications and the Trusted MSP badge, and each tells you something different.

How does our IT provider affect what we tell our insurer and clients?

Increasingly, quite a lot. Professional indemnity insurers and clients ask law firms about their supply chain security, and the IT provider is part of that chain. If you can point to independent verification of your provider's controls, you're answering that question with evidence. It also helps with the SRA's expectation that firms report serious incidents, since a well-run provider is part of how quickly you spot and respond to one.
