Web Application & API Penetration Testing
Web application penetration testing is a security assessment that simulates real-world attacks against your web apps and APIs to uncover exploitable vulnerabilities before attackers do. StealthNet AI combines AI-driven coverage with senior pentester validation for audit-ready results.
What we test
Comprehensive coverage of the attack surface most relevant to this engagement.
Injection attacks
SQL injection, XSS, command injection, SSRF, and template injection across endpoints and parameters.
Authentication issues
JWT vulnerabilities, session fixation, weak passwords, MFA bypass, and brute-force resistance.
Authorization flaws
IDOR, privilege escalation, broken access control, and admin route protection bypasses.
API-specific risks
Mass assignment, BOLA, missing rate limiting, schema validation gaps, and verb tampering.
Business logic flaws
Workflow abuse, race conditions, payment manipulation, and tenant isolation failures.
Client-side issues
DOM XSS, prototype pollution, postMessage abuse, and insecure third-party scripts.
How it works
A clear, repeatable process from scope to remediation.
Scoping
Define apps, APIs, user roles, and compliance goals in a short kickoff call.
Testing
AI agents map the surface and probe at scale. Senior pentesters validate and chain findings.
Reporting
Audit-ready report with severity, evidence, and remediation guidance.
Remediation
Slack support during fixes plus complimentary retesting on confirmed issues.
