Web application penetration testing
We test your application the way a motivated attacker would: with valid accounts, an intercepting proxy, and the time to understand how it works. Scanners catch the obvious issues. We focus on broken authorization, business logic flaws, and low-severity issues that chain into serious ones.
What we test
- Authentication, session handling, password reset, and MFA bypass
- Authorization between users, roles, and tenants (IDOR and privilege escalation)
- Injection: SQL, NoSQL, OS command, template, and cross-site scripting
- Business logic abuse: pricing, workflows, limits, and race conditions
- File upload, server-side request forgery, and deserialization
- Client-side security: CSP, CORS, postMessage, and DOM-based flaws
- Multi-tenant isolation in SaaS platforms
- TLS, cookie, and security header configuration
How we approach it
Every role you give us is tested against every other role. Automated tooling covers breadth, and testers spend most of the engagement on manual work: mapping the application, reading client-side code, and trying the things that only make sense once you understand what the application is for.
What you get
- Executive summary written for leadership and customers
- Technical findings with CVSS scores, evidence, and reproduction steps
- Specific remediation guidance for each finding
- One retest of reported findings within 90 days, with an updated report
- Attestation letter you can share with customers and auditors
Typical use cases
- Before a major launch or redesign
- SOC 2, ISO 27001, or HIPAA evidence
- A customer or partner has asked for a recent pen test report
- After significant changes to login, roles, or permissions
