// Penetration Testing That Finds What Scanners Miss
Manual Testing, Real Results
Our penetration testing services put a human being in front of your systems. A scanner tells you a port is open. It cannot tell you that the open port, combined with a predictable session token and a forgotten admin account, gets someone into your customer database in four steps.
That chain is what we look for, and it is the part automated tools miss every time.
We test web applications, APIs, internal and external networks, cloud environments and mobile apps for businesses across the UK, with a lot of that work in Manchester and London. Every finding is proved by hand before it reaches your report, so you are never chasing a false positive. You get the evidence, the reproduction steps, the fix, and a free retest once your team has made the change.
- Manual, Not Just Automated Testing
- Zero False Positives
- Clear, Actionable Reporting
- Certified Testers in OSCP, CISSP and GPEN
