Offensium Vault provides remote penetration testing for businesses across the United Kingdom, from London to Manchester, Birmingham, Edinburgh and beyond.
We are based in India, a few hours ahead of the UK, so our working day overlaps with yours for calls and updates, and testing can continue after your office closes.
Testing for UK security and data protection requirements
UK organisations are expected to protect personal data and show their controls work. We help you produce clear evidence for:
- UK GDPR and the Data Protection Act 2018, which require appropriate technical security measures
- Cyber Essentials and Cyber Essentials Plus: we help you find and fix gaps before your assessment (certification itself is issued by accredited certification bodies)
- ISO 27001 and SOC 2 audits
- PCI DSS for payment environments
- Client and supplier security reviews

How a remote engagement works
- Scoping call and NDA. We agree what is in scope, the rules of engagement and the testing window.
- Manual, evidence-based testing. Tools support the work, but every finding is verified by hand.
- Live updates on critical issues. Serious findings are shared as soon as they are confirmed, not held for the final report.
- Clear report and walkthrough. An executive summary, technical findings with evidence and business impact, and step-by-step fixes.
- Retest. We verify your fixes so “fixed” really means fixed.
Testing windows and walkthrough calls can be agreed around UK business hours.
