You wouldn't open a high street shop and leave the back door unlocked. Your web application is your shop front — except it faces 4 billion potential visitors. We find the unlocked doors before someone else walks through them.
Here's an uncomfortable asymmetry: the average cost of a web application penetration test is a fraction of your annual IT budget. The average cost of a data breach in the UK is £3.4 million. That's not a security decision — it's a maths problem. And the maths is embarrassingly one-sided.
Every form field, every API endpoint, every authentication flow in your web application is a potential entry point. Automated scanners will find the obvious issues — the ones script kiddies find too. What they won't find are the business logic flaws, the chained vulnerabilities, the subtle authorisation bypasses that a skilled attacker will exploit to turn your application into their application.
Our web application penetration testing goes far beyond running a scanner and handing you a PDF. We think like the attackers who target your specific industry, your specific technology stack, and your specific business logic. Because that's exactly what they'll do.
People don't buy penetration testing because they enjoy spending money. They buy it because the regret of not testing is catastrophically larger than the cost of testing. This is loss aversion working in your favour — the smartest security investment is the one that makes the worst day of your career simply never happen. Think of it as the cheapest insurance policy you'll ever take out, except this one actually prevents the fire.
We test your web applications against the OWASP Top 10 as a baseline — then go significantly further. Because attackers don't stop at the top ten, and neither do we.
Our testing follows a structured methodology rooted in OWASP and PTES, enhanced by the real-world attack experience of our testers. We don't just run tools — we think like the people who want your data.
We offer three approaches depending on your objectives and the maturity of your application:
| Approach | What We Know | Best For |
|---|---|---|
| Black Box | Nothing but the URL. We approach your application exactly as an external attacker would — no credentials, no documentation, no insider knowledge. | Realistic external threat simulation. Tests your application's resilience against unauthenticated attackers. |
| Grey Box | User credentials for each role, basic documentation, and API specs. The most efficient approach for maximising coverage. | The sweet spot. Tests both unauthenticated and authenticated attack surfaces within a fixed timeframe. Our most popular approach. |
| White Box | Full source code access, architecture diagrams, admin credentials, and database schemas. | Maximum depth. Ideal for critical applications handling financial data, healthcare records, or sensitive personal information. |
A penetration test tells you where you stand today. But your application changes with every deployment, every dependency update, every new feature. Attackers don't wait for your next annual test — they probe continuously.
For continuous monitoring, see our SOCinaBox managed SOC service — 24/7 threat detection, log analysis, and incident response that keeps watching long after the pen test report is filed.
Combine annual web application penetration testing with continuous monitoring from SOCinaBox. The pen test finds the structural weaknesses. The SOC catches the exploitation attempts in real time. Together, they create a security posture that's dramatically harder to breach than either alone.
Every engagement starts with a free, no-obligation scoping call. We'll assess your application, define the scope, and give you a clear quote — no surprises, no pressure. The only cost you should worry about is the cost of doing nothing.
