Web Application Penetration Testing
Identify vulnerabilities in your web applications before attackers do.
What this assessment covers.
Web applications are among the most targeted assets in any organisation’s digital footprint. DERISK’s Web Application Penetration Testing service provides a deep, expert-led assessment of your application’s security posture, simulating real-world attacker techniques to uncover vulnerabilities that automated scanning alone cannot detect.
Our assessments go beyond surface-level checks. We analyse authentication flows, session management, access control logic, input validation, and business logic flaws that could allow privilege escalation, data exposure, or unauthorised access. Every finding is manually validated to ensure zero false positives and delivered with clear, developer-ready remediation guidance.
How we test.
A structured, expert-led methodology from initial reconnaissance through to real-time reporting and remediation guidance.
- 01
Reconnaissance and mapping of the application surface
We begin by mapping your application’s full attack surface — endpoints, parameters, authentication flows, and hidden functionality — to understand how the app behaves and where it might be vulnerable.
- 02
Authentication, session, and access control testing
We rigorously test login mechanisms, session tokens, and role-based access controls to ensure users can’t escalate privileges, hijack sessions, or access data they shouldn’t see.
- 03
Vulnerability exploitation and business logic analysis
Beyond standard checks, we probe injection points, input validation, and application-specific business logic to uncover flaws that automated scanners miss.
- 04
Real-time findings published to the DERISK PTaaS portal
As vulnerabilities are confirmed, they are immediately published to the PTaaS portal with proof-of-concept evidence so your team can start remediation without waiting for the final report.
- 05
Report and recommendations with remediation guidance
You receive a comprehensive report with risk-rated findings, CVSS scores, and developer-ready remediation steps prioritised by business impact.

Web App Pentest questions.
What does a web application penetration test cover?
DERISK maps the full application surface, then tests authentication flows, session management, role-based access control, input validation, injection points and application-specific business logic. Coverage is aligned with the OWASP Top 10 and OWASP Testing Guide, but goes beyond them to find the logic flaws automated scanners cannot reason about.
How is this different from an automated vulnerability scan?
A scanner matches signatures. Our testers reason through attack chains the way an adversary does, combining lower-severity issues into critical paths and confirming exploitability by hand. Every finding is manually validated before it reaches you, which is how we deliver zero false positives.
How quickly will we see results?
Initial confirmed findings appear on the DERISK platform within 8 hours of kickoff, critical issues are validated and published within 2 hours of discovery, remediation retests complete within 24 hours, and the full report lands within 2 business days of engagement close.
Will testing disrupt our production application?
No. Scope, timing and intensity are agreed before testing begins, destructive techniques are excluded by default, and you can pause or stop an engagement from the platform at any point. Most clients test production directly; staging is also supported where the environments match.
Often scoped together.
