Web Application Penetration Testing
Identify real-world vulnerabilities before attackers do
We simulate the attacks your application will actually face. Our testers work by hand through authentication, authorisation, and business logic — the classes of flaw a scanner cannot reach — and prove every finding with a working exploit before it reaches your report.
Scope
What the engagement covers
- OWASP Top 10 and business logic flaw discovery
- Authentication, session, and access control testing
- Exploit validation with CVSS and business risk rating
- Developer-ready remediation guidance with code examples
- API endpoint security assessment
- Client-side and DOM vulnerability detection
Outcomes
Why teams choose this
Exploit-verified findings
Every issue is reproduced by hand, so your team never spends a sprint chasing a false positive.
Business context
Risk is rated by what a breach would actually cost you, not by scanner severity alone.
Developer-friendly
Each finding ships with the vulnerable request and a concrete fix for your stack.
Retest included
We verify your fixes and reissue the report once remediation lands, at no extra cost.

Questions
Frequently asked
How long does an engagement take?
A single application typically takes five to ten working days, depending on the number of user roles, workflows, and integrations in scope. We agree the window with you before any testing starts.
Will testing affect production?
We prefer a staging environment that mirrors production. Where production testing is genuinely required, we agree rate limits, testing windows, and a named escalation contact in advance.
Do you provide a certificate for compliance?
Yes. We issue a letter of attestation alongside the report, which is accepted for SOC 2, ISO 27001, and most customer security reviews.
