Security Assessment
Web Application Penetration Testing
Manual testing of web applications and APIs for injection, broken access control, authentication flaws and business-logic abuse.
- OWASP Top 10 and OWASP API Security Top 10 coverage
- Authentication, session and password-reset flow testing
- Broken access control and IDOR testing across roles
Deep testing of your applications and APIs
Overview
Automated scanners are good at finding known patterns and blind to the flaws that matter most. Broken access control, insecure direct object references and business-logic abuse all require a human who understands what the application is supposed to do.
We test with multiple privilege levels, attempt horizontal and vertical privilege escalation, probe every authentication and session boundary, and try to make the application do things it was never intended to do.
Web application penetration testing and API penetration testing go beyond automated web application security testing: testers work through authentication, access control and business logic by hand. API security testing covers the APIs behind your web and mobile apps, including the ones users never see.

FAQ
Frequently asked questions
Can you test against staging instead of production?
Preferred, provided staging is a faithful mirror. Where it differs materially we agree a limited, carefully scoped production validation pass.
Do you test single-page applications and APIs?
Yes. Modern SPA and mobile back-ends are API-first, and we test the API surface directly rather than only through the browser interface.
Ready to move on Web Application Penetration Testing?
We will scope it against your actual environment, not a generic package, and give you a fixed price before any work starts.
