What is different about IT in a law firm?

The systems are common ones. The stakes are not: privileged client material, client money and your own accountability.

Privileged client data: Matter files, emails and documents are confidential and often privileged. Access has to be controlled and logged, and leavers have to lose access the same day.
Fee earners and billable time: A slow login or a failed save costs billable hours. Support has to fix the fee earner’s problem fast, not just log a ticket.
Practice and document systems: Case management, document management and time recording sit alongside Microsoft 365. Keeping them joined up and secure takes planning. Tell us which you use.
Client account and payment fraud: A changed bank account in an email can cost a firm tens of thousands of pounds. Defending against it is partly IT and partly process.
Accountability for outsourced IT: The firm stays responsible when IT is outsourced. You need to know what your provider runs, and be able to show it.
Joiners, leavers and lateral hires: New fee earners need accounts and the right access on day one. Leavers need access removed straight away.

A changed bank account in an email can cost a firm tens of thousands of pounds

The National Crime Agency and the Law Society recorded 143 reports of payment diversion fraud in property sales between April 2024 and March 2025, with an average loss of about £82,000 (September 2025). The method is simple: a criminal takes over a real email account, or sets up a look-alike one, then sends new bank details.

It is not exotic malware. It is an account without multi-factor authentication, a hidden forwarding rule, or a sender address one letter out. Those are IT controls we can put in place: multi-factor authentication on every account, monitoring of mailbox rules, and email protections that make look-alike senders easier to spot.

The other half is process, and it is yours: check any change of bank details by phoning a number you already hold, and agree who is allowed to change payee details. Lanmark Total adds 24x7x365 monitoring by a security team on top.

Data breach: the first hour

You stay accountable when you outsource IT

The Solicitors Regulation Authority (SRA) says a firm cannot hand over its responsibility for compliance by getting others to do the work. The ICO has reprimanded a solicitors’ firm that was unaware of the security measures its outsourced IT provider had in place, and had not reviewed that arrangement for years (October 2024).

So the useful question for any IT provider is: can you tell me, in writing, what is running on my systems? With Lanmark you can expect to know what is in place: how access is controlled and logged, how backups are made and tested, what monitoring is running, and who to call.

We do not give legal or regulatory advice, and we do not make a firm compliant. We help you put in place the IT controls that sit underneath your obligations, and what those obligations are is for your compliance officers, your own advisers and the SRA.

Which IT controls support your obligations?

The controls we help you put in place:

Access management, so only authorised people can open matter files and client data.
Multi-factor authentication on every account, including email.
Audit logging, a record of who accessed what and when.
Microsoft 365 backup, so email and documents can be restored.
Incident response planning, so you know what to do and who to call.

What does IT support for a law firm cost?

The price per user is published. Very small practices often start on Flex. Priced per user or per device, whichever is fewer. A firm with twelve staff, some part-time, and ten computers is charged on ten.

What do law firms ask about IT support?

How do we stop a "changed bank details" email being paid?

The strongest control is a call to a number you already hold, never one from the email. On the IT side we protect sign-ins with multi-factor authentication, watch mailboxes for hidden forwarding rules, and help set up email protections that make look-alike senders easier to spot. No IT service removes the risk entirely, so the process and the IT controls need to work together.

What does the SRA expect of us when our IT is outsourced?

The Solicitors Regulation Authority (SRA) says a firm cannot hand over its responsibility for compliance by outsourcing. What that means for your firm is for your compliance officer and the SRA’s own guidance. What we can do is tell you plainly what is in place on your systems, so your compliance officers are not left piecing it together from invoices.

Can you support our case management and document systems?

Tell us which ones you use, whether that is a cloud practice management system, a document management system or both. We go through your specific systems with you at the first meeting and talk through how we can help.

Do you give legal or regulatory advice?

No. We help you put in place the IT controls that sit underneath your obligations, such as access management, audit logging, backup and recovery and incident response planning. What those obligations are is a matter for your compliance officers, your own advisers and the SRA.

Is there support outside office hours?

The service desk runs Monday to Friday. 24x7 support is available on request.

Can a very small practice use Lanmark?

Yes. Very small practices, usually under ten people, often choose Lanmark Flex, a prepaid pack of support hours with no contract. Most practices choose Lanmark Total.

How quickly can you take over from our current IT provider?

SmoothSwitch starts with a free IT review and a free 30-day trial with Lanmark running alongside your current provider, so the handover is checked against live tickets.
