Lanmark provides managed IT support to law firms and legal practices across London. We understand that a law firm’s IT environment is not simply infrastructure — it is the system through which you handle confidential client data, manage billing, maintain regulatory obligations, and keep your practice running. Getting it wrong has professional and legal consequences. Our service is built to ensure it does not go wrong.
As holders of Microsoft’s Support Service Designation, an accreditation held by fewer than a dozen companies worldwide, we bring an independently verified standard of technical expertise to every engagement. Our pricing is per user, per month — making costs predictable for firms of any size.
Why law firms need specialist IT support
A law firm’s IT requirements are different from those of a generic office environment in several important respects.
First, confidentiality. Your client data is subject to legal professional privilege and strict confidentiality obligations. The systems that hold that data — your practice management platform, your document management system, your email — must be secure, access-controlled, and auditable. A general IT provider without legal sector experience may not fully appreciate the implications of a data breach or an access control failure in this context.
Second, regulation. The Solicitors Regulation Authority (SRA) expects firms to have appropriate systems and controls in place to protect client data and maintain operational resilience. The ICO’s GDPR obligations apply to client and matter data in the same way they apply to any business — but the consequences of a breach are amplified by the professional dimension. Lanmark helps firms implement the IT controls appropriate to these obligations.
Third, system complexity. Modern law firms typically run a combination of cloud-based practice management, document management, and time-recording systems alongside Microsoft 365 for communications and file storage. Managing this environment — and keeping it integrated, secure, and performant — requires experience rather than generalism. Increasingly, law firms are also asking how to use AI safely with confidential client data — our AI consultancy covers Microsoft 365 Copilot deployment with the SRA-aligned governance the legal sector needs.
Cybersecurity for law firms — the risk is not theoretical
Law firms are a high-value target for cyber attackers. Client accounts, confidential deal data, litigation materials, and large sums held in client accounts make a successful attack extremely lucrative. The NCSC has specifically highlighted the legal sector as a priority target for ransomware groups and business email compromise campaigns.
The response most firms default to — antivirus software and a basic firewall — is no longer sufficient. Modern attacks use compromised credentials, legitimate software tools, and slow-burn techniques designed to evade detection. By the time a conventional security product raises an alert, the attacker has often already achieved their objective.
Lanmark’s Managed Detection and Response (MDR) service provides 24/7 monitoring of your environment by a dedicated Security Operations Centre (SOC). Security analysts watch your systems around the clock, looking for anomalous behaviour that automated tools would not flag. When something is detected, the response is immediate. This is not theoretical protection — it is continuous, active monitoring by people whose sole responsibility is the security of your environment.
This level of security was previously only accessible to large organisations with significant security budgets. Lanmark makes it available to law firms at SMB pricing. For a practice that holds sensitive client information, it is no longer an optional enhancement — it is the baseline that professional obligations increasingly demand.

SRA compliance readiness and IT governance
The SRA’s Codes of Conduct and associated guidance place clear expectations on law firms around data protection, cybersecurity, and operational resilience. While Lanmark does not provide legal or regulatory advice, we support law firms in implementing the IT controls and processes appropriate to these requirements.
This includes access management (ensuring only authorised individuals can access matter files and client data), audit logging (maintaining records of who accessed what and when), data backup and recovery (ensuring client and matter data is recoverable in the event of a system failure), and incident response planning (knowing what to do and who to call if something goes wrong).
Many firms find that an annual IT review — examining their systems, access controls, and security posture — is a straightforward way to identify gaps before a regulator or auditor does. We provide this as part of our managed service.
Microsoft 365 and cloud infrastructure for law firms
Microsoft 365 has become the dominant platform for legal sector communication, file storage, and collaboration. As a Microsoft Direct Cloud Solution Provider, Lanmark supplies M365 licences at discounted rates and manages the full lifecycle of your Microsoft environment — from initial configuration and migration through to day-to-day administration and support.
For firms considering moving case management or document management to a cloud-hosted platform, Lanmark has direct experience of migrating legal practices from on-premise infrastructure to cloud environments without disruption to billing cycles, matter continuity, or client communication.
If you are unsure whether your current M365 licences are correctly configured for your practice’s needs, we offer a free licence review. Many firms are either over-licensed in areas they do not use or under-licensed in areas that would deliver genuine productivity gains.
Per-user pricing — IT costs that scale with your firm
Law firm headcount is not static. Trainees join in cohorts, lateral hires expand teams, and seasonal pressures create fluctuations. A per-device IT support contract creates friction at every headcount change: new machines need adding, departing staff’s devices need removing, and the bill rarely reflects the actual size of the practice at any given point.
Lanmark’s per-user pricing model removes this friction entirely. Every member of staff is covered across all their devices for a single monthly user fee. When the firm grows, the cost scales proportionately. When it contracts, so does the bill. There are no call-out charges, no per-incident fees, and no surprise invoices at the end of a difficult month.
Frequently asked questions
Do you provide IT support for smaller law firms and sole practitioners? Lanmark’s primary focus is practices in the 20-500 user range, where our managed service model is most effective. For smaller practices, minimum engagement thresholds may apply. We are happy to discuss your specific requirements directly.
How do you handle client data confidentiality? All Lanmark engineers operate under data processing agreements that comply with UK GDPR requirements. Access to client systems is controlled, logged, and subject to strict internal governance. We do not access client data beyond what is necessary to deliver the service and resolve support issues.
Can you support our practice management system? Lanmark works across a broad range of legal software environments. Compatibility with your specific systems is assessed as part of the onboarding process. Please contact us with details of the platforms you use and we will confirm our experience with them.
What happens if we experience a cyber attack or ransomware incident? Firms with Lanmark’s MDR service benefit from 24/7 monitoring that is designed to detect and contain threats before they become incidents. If an incident does occur, our security operations team responds immediately and the engagement transitions into an active incident response posture. We are able to discuss incident response planning as part of your service agreement.
Are you familiar with SRA IT and data security requirements? Yes. We support a number of London law firms and are familiar with the SRA’s expectations around data protection, cybersecurity, and operational resilience. We work alongside firms’ compliance teams to ensure IT controls are appropriate and documented.
How quickly can you transition from our current IT provider? Transition timelines depend on the complexity of your existing infrastructure. We manage the full handover process — discovery, documentation, and cutover — to minimise disruption to the practice. In most cases, a smooth transition can be completed without any visible disruption to day-to-day operations.
