Web Application Penetration Testing
Manual web application penetration testing that goes beyond automated scanners. Full OWASP Top 10 coverage, business logic testing, and developer-ready reports for SaaS and startup teams.
Overview
Automated scanners catch the obvious. The vulnerabilities that actually get companies breached — broken access control, chained logic flaws, subtle authentication bypasses — take a human who understands how your application is meant to work and how to break that intent.
A web application penetration test simulates a determined attacker against your app. I map the full attack surface, test every role and workflow by hand, and prove impact with real, reproducible exploits — not theoretical severity scores.
What you walk away with
- Every finding manually verified with a working proof of concept
- Risk-rated report with CVSS scores and clear business impact
- Step-by-step remediation guidance your developers can act on
- Free retest to confirm your fixes actually close the issue
What gets tested
A representative view of the attack surface I probe by hand during this engagement.
Broken Access Control
IDOR, forced browsing, horizontal and vertical privilege escalation across every user role.
Injection
SQL, NoSQL, command, template, and header injection across all inputs and parameters.
Authentication & Sessions
Login, MFA, password reset, session fixation, and token handling weaknesses.
Cross-Site Scripting
Reflected, stored, and DOM-based XSS, plus CSP and output-encoding review.
Business Logic
Workflow abuse, race conditions, price and quantity tampering, and multi-step bypasses.
Server-Side Flaws
SSRF, insecure deserialization, file upload abuse, and misconfigured security headers.
Web Application Penetration Testing — common questions
Most engagements run one to three weeks depending on the size of the application, the number of user roles, and the complexity of the business logic. You get a clear timeline and scope before any testing begins.
Testing is deliberately careful. I favor a staging environment where possible, avoid destructive payloads, and coordinate any potentially disruptive checks with your team in advance so there are no surprises.
Typically a test environment, test accounts for each user role, and any relevant documentation. Signed authorization and a defined scope are required before testing starts.
