Cyber Essentials for Law Firms

Law firms hold exactly what attackers want, client funds, privileged correspondence and identity documents, and certification is no longer optional for everyone: since 1 October 2025, practices holding Criminal Legal Aid contracts must hold a valid Cyber Essentials certificate as a contractual requirement, and panel and insurer questionnaires increasingly expect it from the rest.

RedSecLabs is preparing to offer Cyber Essentials certification services with an understanding of how law firms actually run: case management systems, dictation workflows, fee earners on personal devices, and legacy practice management software that complicates the “supported software” rule.

We help firms scope honestly, remediate pragmatically, and pass under the 2026 requirements without disrupting fee-earning work.

What certification looks like in a law firm

The five controls map cleanly onto how a modern firm works. Firewalls and secure configuration cover your office network and any hosted practice management environment. Security update management is where legacy legal software bites, unsupported Windows servers running an old PMS are the most common blocker we see, and under the 2026 rules they are an automatic failure if left in scope. User access control means fee earners work without admin rights and leavers lose access on their last day, not at the next IT visit. Malware protection and enforced MFA on email close off the phishing and payment-fraud route that causes most legal-sector losses.

Cloud-hosted case management platforms count as cloud services under the 2026 definition: they belong on your asset list, and MFA must be enabled where the platform supports it.

What Cyber Essentials gives a law firm:
A recognised answer to lender-panel and client security questionnaires
Concrete evidence of SRA-relevant safeguards for client information and money
MFA-enforced email, the control that blocks most payment-redirection fraud
A structured reason to finally retire unsupported legacy systems
Stronger cyber insurance position at renewal
A baseline that Lexcel and ISO 27001 can later build on

For most firms, the certification project doubles as the risk-reduction project they already knew they needed, with a certificate at the end that clients recognise.

The legal sector's specific exposure

Attackers target law firms because the economics are excellent: a single compromised mailbox during a conveyancing transaction can redirect a six-figure completion payment, and privileged material creates ransomware leverage most businesses don't face. Client account rules mean losses are not just financial but regulatory.

None of the common attacks are sophisticated. They exploit exactly the gaps the five controls close: no MFA on email, stale patching, everyone an admin, and no control over the devices partners use at home. That is why buyers of legal services now check for the certificate.

Common gaps we see in law firms:
No MFA on email, the direct route to conveyancing and invoice fraud
Unsupported servers kept alive for a legacy practice management system
Fee earners using personal devices with no controls for client documents
Shared logins for support staff and no leaver process
Local admin rights firm-wide because “IT set it up that way years ago”
Backups untested and reachable from the main network, ransomware's best friend

Every one of these is fixable in weeks, and every one has caused a real UK firm a real loss. Certification forces the fixes onto a deadline.

Frequently Asked Questions

For some, yes: since 1 October 2025, any practice holding a Criminal Legal Aid contract must hold a valid Cyber Essentials certificate as a Legal Aid Agency contractual requirement, and because certificates expire after 12 months, that means renewing every year without a gap. Beyond legal aid, it is not an SRA rule, but lender panels, insurers and corporate clients increasingly require it, and the SRA expects firms to protect client money and information; certification is the most recognised way to evidence the technical basics.

If the operating system or the PMS version is unsupported and receives no security updates, it cannot remain in scope as-is, under the 2026 rules unsupported software is an automatic failure. Options: upgrade, migrate to the vendor's cloud version, or properly segregate the system out of scope. We help firms pick the least disruptive route.

If they access client emails, documents or firm systems, yes, they are in scope under the 2026 remote-working rules and must meet the controls (supported OS, updates, screen lock, malware protection). Many firms solve this with firm-issued devices or lightweight management on personal ones.

Done properly, minimally. The noticeable changes are MFA prompts and losing day-to-day admin rights, both quick adjustments. We schedule remediation around court dates and completions, and most technical work happens with your IT provider outside working hours.

Generally yes. Insurers increasingly ask directly about MFA, patching and backups, the CE controls, and eligible firms under £20m turnover also receive £25,000 of cyber liability cover included with certification. Some insurers offer better terms for certified firms.

They do different jobs: Lexcel is practice management quality, Cyber Essentials is verified technical security. CE is faster and cheaper, and its evidence supports the information-management elements of Lexcel. Most firms without either should do CE first, it closes live risks immediately.
