Law Firm Cyber Security: Lessons From the NCSC Report

The National Cyber Security Centre (NCSC) has published a cyber threat report aimed specifically at UK law firms, and it is relevant to practices of every size, from sole practitioners to large partnerships. If you run or work in a legal practice, it is a useful prompt to check that your defences match the risk you carry.

Law firms are an attractive target for one simple reason: they hold exactly what criminals want. Sensitive client information, confidential case details, and often significant sums of client money moving through conveyancing and settlements. That combination makes strong law firm cyber security a professional obligation as much as an IT decision.

Why law firms are targeted

The value concentrated in a legal practice is unusually high. A single mailbox can hold confidential correspondence, identity documents and payment details for dozens of clients. Client account funds make firms a prime target for payment redirection fraud. And the duty of confidentiality means a breach is not only disruptive and costly, it can undermine the trust a practice depends on and raise difficult questions with regulators, clients and insurers.

The threats that matter most

Phishing and business email compromise. Convincing emails that impersonate a colleague, a client or the other side in a transaction remain one of the most common ways in, and are especially dangerous around the movement of funds.

Ransomware. Attackers encrypt or steal case files and demand payment, bringing a practice to a standstill and threatening to leak confidential material.

Data theft. Even without ransomware, stolen client data carries reporting obligations and reputational cost.

Meeting your obligations

Alongside the NCSC’s guidance, solicitors face expectations from the SRA around protecting client information and client money, and clients themselves increasingly ask about security before instructing a firm. Working towards recognised standards such as Cyber Essentials, and for larger firms ISO/IEC 27001, gives you a clear framework and something concrete to point to when asked.

Practical steps for your firm

1. Turn on multi-factor authentication across email and case management systems. It is the single most effective defence against stolen passwords.
2. Train the whole team on payment fraud. Verify any change of bank details by phone using a known number, never by replying to the email that requested the change.
3. Keep systems patched. Apply updates to your practice management software, operating systems and devices promptly.
4. Back up case data and test that you can restore it, keeping a copy separate from your main systems.
5. Control access. Give staff access only to the matters they need, and remove access promptly when people leave.
6. Work towards Cyber Essentials. Use Cyber Essentials as a practical checklist and a signal to clients that you take their data seriously.
