GDPR Penetration Testing
CREST-accredited penetration testing scoped to UK GDPR Article 32, the duty to regularly test the effectiveness of your security. You get a fixed price, a named UK-based tester, and a report that stands up as evidence to an assessor, an auditor, or the ICO. Free retests are included.
- Unlimited retesting
- Unlimited pre-retesting
- No hidden fees
When the deadline cannot move, these named UK teams chose EJN Labs and got the result on the timeline they needed
Real EJN Labs clients, named with their permission. They chose us for accreditations they can verify and a CREST team that replies fast, not a sales pipeline.
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.
- CREST approval, publicly verifiable
- IASME Cyber Essentials body
- Active testing within 24 hours
- 100% UK-based testers

the security measures Article 32 lists. The fourth is a process for regularly testing that the other three actually work, and penetration testing is how you evidence it.
GDPR never says “penetration test”. Article 32 still requires you to prove your security works
UK GDPR does not contain the phrase “penetration testing” anywhere in its text. What Article 32(1)(d) does require is a process for regularly testing, assessing and evaluating the effectiveness of your technical and organisational measures.
A firewall you never test, a web application you assume is hardened, an access control you have not challenged: none of these are evidence of effectiveness. Both the ICO and the NCSC point to penetration testing as the recognised way to gain that assurance. For the full legal breakdown, read our guide on whether GDPR requires penetration testing.
We scope every engagement to Article 32, so the deliverable is evidence you can put in front of an assessor, an auditor, or the ICO after an incident. Findings are triaged by risk, remediation is practical, and a retest to confirm your fixes is included.
UK GDPR ARTICLE 32
What a GDPR Penetration Test Covers
Article 32 sets an outcome, not a checklist: your security measures must be regularly tested for effectiveness. Here is how we turn that duty into concrete testing across the systems that process personal data.
Regular testing of effectiveness
the limb that drives penetration testing, a process to test, assess and evaluate whether your controls actually work.
Confidentiality, integrity, availability and resilience
the Article 32(1)(b) measures, tested in practice rather than assumed.
APIs
the interfaces that move personal data between systems and third parties.
Access controls
whether authentication, authorisation and segregation hold up when challenged.
Applications
the web applications that process personal data, tested for business-logic and access-control flaws.
Infrastructure
external and internal network, hosts and services around your personal-data processing.
Significant-change testing
industry norm and ICO / NCSC guidance. UK GDPR Article 32(1)(d) requires a process for regularly testing effectiveness but sets no interval, so a material change to systems processing personal data is a sensible trigger to retest.
METHODOLOGY
How a GDPR Engagement Runs
From mapping the systems that process personal data to an evidence-ready report and the retest that confirms your fixes, here is how the engagement runs.
Scope
We map the systems that process personal data, agree the Article 32 outcomes to evidence, and fix the price and timeline.
Test
Applications, APIs, external and internal infrastructure and access controls, with findings shared live to your portal.
Report
An evidence-ready report with an executive summary, technical detail, and each finding tied to the Article 32 duty it informs.
Retest
We verify your remediation and issue a letter of attestation you can show an assessor or the ICO.

FAQ
Frequently Asked
How long does a GDPR penetration test take?
Typically 2 to 8 days, depending on the number of systems that process personal data. We confirm the timeline with your fixed quote.
Do I get a named tester?
Yes. A named, CREST-accredited, UK-based consultant runs your test and stays available throughout.
Who is qualified to perform a GDPR penetration test?
A qualified, independent tester. UK GDPR names no scheme; CREST accreditation is widely accepted as evidence of competence.
Is a vulnerability scan enough on its own?
No. A scan is a useful input but does not demonstrate effectiveness; Article 32 points to testing that challenges your controls.
What happens if you find vulnerabilities?
We triage by risk, give practical remediation, and a retest to confirm the fixes is included.
Will the report help satisfy an assessor, auditor or the ICO?
It is built as the evidence they expect: how you test the effectiveness of your Article 32 controls, findings triaged by risk, and remediation confirmed on retest.
Do you retest after we fix issues?
Yes. Retests are included so you can show the fixes held.
