CREST-accredited penetration testing Services
CREST-accredited penetration testing for the legal sector
Law firms sit on exactly what attackers want: personal and financial data, privileged and commercially sensitive material, and, for firms handling conveyancing, probate, litigation settlements or completions, money in motion. Ransomware crews, business email compromise and payment-redirection fraud all target the profession specifically, precisely because a single successful attack can be so lucrative and so damaging.
Our penetration testing for law firms is tailored to that reality. Whether you are testing to protect confidential client data, to satisfy the SRA’s expectations, to meet a Lexcel, Cyber Essentials or ISO 27001 requirement, or to pass an insurer’s or panel’s due diligence, every engagement is scoped around your environment and the real-world threats your practice actually faces.
You work directly with a qualified tester who understands the duties of confidentiality and privilege you operate under, not a call centre and not an offshore checklist.

Not sure which test you need?
Most people searching “pen test” aren’t sure yet, that’s normal. Pick the closest match, or talk it through directly with a tester. We can incorporate multiple testing types for a single project. We often do web app + network testing if a business wants to cover both.

Our Values
What’s in your penetration testing report
The report is where a penetration test earns its value. A test is only as useful as the document that comes out of it, and ours are built to be read and acted on, not filed away. Every engagement ends with a clear, structured report that works for your technical team and your senior stakeholders alike.

When does a law firm need a penetration test?
Penetration testing isn’t a one-off box to tick. It’s something to build into the key moments of your business. You should consider a test when:
Not sure which of these applies to your firm? A quick scoping conversation will tell you what you need, and, just as importantly, what you don’t.
LIVE REPORTING
Stay informed throughout your penetration test with real-time access to findings through our secure client portal.
As vulnerabilities are identified, they’re immediately available for your team to review, giving you complete visibility into the assessment as it progresses. Any High or Critical findings are communicated straight away via your agreed contact channels, ensuring urgent risks are never left waiting until the final report.
Our collaborative approach also allows for interactive re-testing during the engagement. As fixes are implemented, our consultants can validate them in real time, helping to reduce outstanding vulnerabilities before testing is complete.
At the end of the engagement, your portal is updated with the final quality-assured report, providing a comprehensive record of the assessment, findings, remediation guidance, and supporting evidence.

Penetration testing FAQs
Cloud providers secure the underlying infrastructure, but securing how you configure and use their services is your responsibility. Our testing focuses squarely on that customer side, where the vast majority of cloud breaches actually occur.
Yes. Our support doesn’t end at the report. Once you’ve addressed the findings, we can retest to confirm the fixes are effective, giving you and your stakeholders verified assurance that the risks have been closed.
The cost depends on scope: the size and complexity of your network, the number of live hosts and sites, and whether you need internal testing, external testing, or both. Rather than quote a misleading flat rate, we scope every engagement individually so you only pay for testing that delivers real value. Get in touch for a tailored quote.
Yes. APIs are one of the most common sources of serious vulnerabilities, so every connected endpoint receives the same scrutiny as the application itself, including tests for authentication gaps, excessive data exposure, and broken object-level authorisation.
Industry best practice is to test at least annually, and after any significant change to your infrastructure or applications. Frameworks such as PCI DSS and ISO 27001 typically require annual testing. We’ll help you define the right cadence for your organisation.
In black box testing the tester has no prior knowledge of the application. In white box testing they have full access to code and documentation. Grey box sits in between, with partial knowledge for a realistic yet efficient assessment. We’ll help you choose the right approach for your goals during scoping.
No. Wherever possible we test against a non-production environment such as UAT or QA, so there’s no risk to your live service. If that isn’t possible, we take a more cautious approach to post-exploitation testing to protect your users.
A vulnerability scan is automated and flags known issues. A penetration test adds expert human analysis, actively exploiting weaknesses to understand the real business impact and uncovering the misconfigurations, credential issues, and lateral movement paths that scanners simply cannot find.
