If you run a small law firm or solicitors practice, cybersecurity is no longer optional — it’s a professional obligation.

The Solicitors Regulation Authority (SRA) Code of Conduct requires firms to have appropriate and proportionate measures in place to protect client data and prevent unauthorised access. And in 2026, what counts as “appropriate and proportionate” is being interpreted more strictly than ever.

What Does the SRA Require?

The SRA doesn’t publish a specific technical checklist — the standard is “appropriate and proportionate” which means it varies based on the size and nature of your firm and the data you handle.

In practice, the SRA expects law firms to:

When the SRA investigates a firm following a breach, it looks at whether these elements were in place. A firm that had made genuine efforts to assess and address its risks is in a very different position to one that had done nothing.

What Are the Biggest Cyber Risks for Small Law Firms?

Email compromise: Law firms are targeted specifically because they handle high-value financial transactions and privileged communications. A compromised email account can be used to intercept client funds or extract confidential information.

Case management system access: If your case management software isn’t properly secured — particularly around authentication and access controls — it’s a significant vulnerability.

Remote working: Many firms adopted remote working arrangements quickly and haven’t reviewed the security of those setups. VPN configurations, remote desktop access, and home network security are all common weak points.

Supply chain attacks: Criminals increasingly target the suppliers of law firms rather than the firms themselves. If your IT provider, document management company, or any other supplier is compromised, that can create a path into your systems.

Staff as the weakest link: Phishing emails have become dramatically more sophisticated. What was once easy to spot — poor grammar, obvious pretexts — is now highly targeted and convincing. In 2026, AI-generated phishing emails are essentially indistinguishable from legitimate correspondence.

What Should a Small Law Firm Have in Place?

The practical minimum for a small firm in 2026:

Multi-factor authentication on all email accounts and case management systems. This single measure prevents the vast majority of account takeover attacks.

A formal offboarding process that removes system access the moment someone leaves the firm — not weeks or months later.

Regular software updates — within 14 days of release for high-risk patches under current Cyber Essentials requirements.

Documented incident response — you don’t need a complicated plan, but you should know who to call, what to do, and when you’re required to notify the ICO or affected clients.

A basic backup system that’s tested regularly — knowing that your data can be restored is fundamentally different from hoping that it can.
