Web Application Penetration Testing
Every input is a doorway. We treat your application the way a motivated adversary would, chaining flaws through authentication, authorization, and business logic until they become a breach, then handing you the exact map to close them.
What you walk away with
- Full OWASP Top 10 coverage plus logic-layer abuse cases automated scanners never reach
- Reproducible, severity-ranked findings with working proof-of-concept
- Remediation guidance written for engineers, not auditors
A methodology built on manual exploitation
Automated scanners find the obvious. Real risk lives in the seams, a role check missing on one endpoint, a token that never expires, a workflow that can be replayed for profit. Our testers combine authenticated and unauthenticated perspectives, model your application's trust boundaries, and pursue exploit chains end to end. Coverage is aligned to the OWASP Web Security Testing Guide and calibrated to the way your specific product actually works.
What we test
- Injection: SQL, NoSQL, command, template, and ORM-layer injection with full data-exfiltration proofs
- Cross-Site Scripting (XSS): reflected, stored, and DOM-based, including CSP-bypass techniques
- Authentication: credential handling, MFA logic, session lifecycle, and account-recovery abuse
- Authorization: horizontal and vertical privilege escalation, IDOR, and broken function-level access control
- Server-Side Request Forgery (SSRF): internal service pivoting and cloud metadata access
- Cross-Site Request Forgery (CSRF) and state-changing action abuse
- Remote Code Execution (RCE): deserialization, file-upload, and dependency-driven paths
- Business logic: pricing, quota, workflow, and race-condition abuse unique to your product
How we work with your team
We start with a scoping session to understand your architecture, roles, and highest-value assets, then run testing in a controlled window with a live channel for critical findings. Nothing waits for the report. If we find something that puts you at material risk, you hear about it the same day.
