Penetration Testing for UK Law Firms (SRA Cyber Standard)
CREST-accredited penetration testing for UK solicitors, barristers’ chambers, conveyancers, legaltech and e-discovery providers. SRA Cyber Standard alignment, privileged data confidentiality, partner-tier procurement, conveyancing fraud defence. Strict NDA, sector-experienced testers.
- Unlimited retesting
- Unlimited pre-retesting
- No hidden fees
“I would highly recommend EJN Labs to any organisation seeking reliable, detailed, and well-managed penetration testing services, particularly for government or enterprise-level projects.”
“There wasn’t another company we could find that could deliver what we needed in the timeframe we needed. The client loved it, and we got instant ROI from the engagement.”
penetration test, scoped to your matter systems and client data, gives you evidence for SRA Cyber Standard work, LOCS:23 certification and the questions on your cyber insurance proposal form.
What SRA Expects from Penetration Testing
SRA Cyber Standard. The Solicitors Regulation Authority’s Cyber Standard requires demonstrable technical security controls. Pen testing is the recognised mechanism for evidencing those controls during regulatory audit.
Privileged Data Confidentiality. Legal client data carries privilege. Engagement scoping covers handling of legally privileged material, NDA-strict reporting, and a redaction model that protects both attacker insight and client privilege.
Partner-Tier Procurement. Major legal clients (financial services, corporates, public sector) audit their law firm’s cyber posture. Our reports map findings to SRA and ISO 27001 controls and to the questions on your cyber insurance proposal form. Requirements vary by insurer and policy.
LOCS:23. The Legal Services Operational Privacy Certification Scheme, the ICO-approved UK GDPR certification for legal services, requires an external and an internal vulnerability scan at least once a year (controls 8.3.7.14 and 8.3.7.15) and lists penetration testing among the protective measures a certified firm evidences (8.3.7.13). Our external and internal scans, penetration test report and letter of attestation give you that evidence in the form a LOCS:23 assessor expects.

FAQ
Frequently Asked
Do you sign legal-grade NDAs?
Yes. EJN signs partner-tier NDAs covering legally privileged information, with explicit obligations on data handling, retention, and sub-processor restrictions. Our standard NDA template is available for your firm’s review pre-engagement.
How do you handle legally privileged material discovered during testing?
Privileged content discovery is contained within the report’s restricted technical appendix, redacted in the executive summary, and never excerpted beyond the engaged law firm. Our testers operate under standing instructions on privilege handling.
Can you test conveyancing fraud defences specifically?
Yes. Our phishing assessments include specific conveyancing wire-fraud scenarios: payment-instruction interception, partner-impersonation BEC, lookalike domain registration, and direct-communication-channel hijacking patterns.
How do you handle the partner / staff role asymmetry?
Engagement scoping defines authorised tester targets (typically the IT-admin tier for credentialed testing, and standard-staff role for phishing simulation). Partners are tested only with explicit Managing Partner authorisation.
Compatible with our Lexcel Practice Management certification?
Yes. Reports include Lexcel control mapping for cyber security clauses. Most law firm clients attach our reports to their Lexcel evidence pack at re-certification.
Does your testing give us the evidence LOCS:23 asks for?
Yes. LOCS:23 (the Legal Services Operational Privacy Certification Scheme, approved by the ICO) requires an external and an internal vulnerability scan at least once a year and lists penetration testing among the protective measures a certified firm evidences. We deliver the external scan, the internal scan and the penetration test, and the report plus letter of attestation are written so your LOCS:23 assessor can use them directly.
Do you provide attestation letters for cyber insurance underwriting?
Yes. Requirements vary by insurer and policy. Some cyber insurance applications ask whether you conduct vulnerability assessments or penetration tests and remediate critical findings. After remediation and the free retest we issue a letter of attestation, and we tailor its wording to the questions your broker or insurer asks where requested.
Can you test an in-progress matter system?
Production matter systems are tested only with explicit Managing Partner authorisation, restricted scope, and no exfiltration. In our experience firms prefer testing on a UAT-tier mirror environment.
Which legal organisations do you test for?
Solicitors’ firms, barristers’ chambers, conveyancers, legaltech vendors, e-discovery providers and legal operations teams.
Can you test our client portal or data room?
Yes. We test matter-level confidentiality and ethical walls, whether a client or share link can reach another matter’s documents, how client identity is verified, and whether payment instructions can be changed without the right checks.
What’s in the report?
Executive summary (board-ready), technical report with CVSS 3.1 scores, reproduction steps, screenshots, specific remediation guidance, and a 60-minute walkthrough call. Letter of attestation issued after free retest.
How quickly can you start?
From signed scope to active testing in 24 hours where required. Standard pipeline is 3-5 business days from initial scoping call to test start.
Are your testers UK-based and what certifications do they hold?
Every engagement is performed by vetted UK-based CREST-certified testers matched to your engagement based on security clearance, compliance scope, and sector specialism. Testers hold CREST certifications relevant to their discipline (CRT, CCT APP, CCT INF, CCSAM).
