Certified penetration testers helping UK businesses identify and remediate security weaknesses — before attackers exploit them.
CISOs and IT leaders comparing providers need a reason to choose. Here’s ours.
Your work is never handed to a junior. Every assessment is conducted by CREST, Cyber Scheme and OffSec certified testers — not outsourced, not templated.
We don’t disappear after delivery. We stay engaged through remediation, answer your team’s questions, and retest to confirm fixes.
The large consultancies treat smaller clients as low priority. You get direct access to your tester, plain-English reporting, and pricing that fits your budget.
Critical findings are communicated immediately — not buried in a report two weeks later. You’ll have a dedicated channel throughout the engagement.
Every report includes an executive summary for non-technical stakeholders, alongside full technical detail for your engineering team.
Leading IT support companies and MSPs across the UK partner with us to deliver testing for their clients — a trust signal that speaks for itself.

Our experience with JAG Secure has been excellent. The testing plan was communicated clearly from the outset. Throughout testing we maintained continuous communication — discovered vulnerabilities were reported immediately. Jordan provided suggestions for how vulnerabilities could be patched which really helped. Far less daunting than anticipated. Our partner recommended JAG Secure and I would recommend them myself for their professionalism and thorough approach.
We engaged JAG Secure to perform security testing on a new software product and its underlying cloud architecture. From the very first call, we felt a genuine sense of partnership. JAG Secure took time to understand what we were building and the outcomes we needed. Communication throughout was excellent. We wouldn’t hesitate to work with JAG Secure again as our product grows.
Tell us what you’re looking to test and we’ll come back with a clear, no-obligation proposal within 24 hours.
We’ll respond within one business day.
