WEB-03 // WEB APP PENETRATION TESTING

Web App Penetration Testing

Break your app before your users (or attackers) do.

// 01 · Mission Profile

Deep, manual testing of your web applications and APIs against the OWASP Top 10 and well beyond it: auth flaws, injection, broken access control and business-logic abuse, found by humans, not just scanners.

What you get out of it

  • Ship features without shipping vulnerabilities
  • Protect customer data and sessions
  • Meet security requirements for clients & audits

Representative findings

[CRIT]Remote code execution via outdated component
[HIGH]Broken access control on privileged endpoints
[MED]Missing security headers & weak TLS configuration
[LOW]Information disclosure in verbose error responses

// representative severities · your real findings come with proof & remediation

Flight plan

  1. 01

    Scope & Recon

    We align on goals, rules of engagement and crown jewels, then map your real attack surface the way an adversary would.

  2. 02

    Attack & Exploit

    Hands-on, manual exploitation using the same tools and techniques as real threat actors, not just an automated scan.

  3. 03

    Escalate & Pivot

    We chain weaknesses, escalate privileges and move laterally to prove genuine business impact, not hypothetical risk.

  4. 04

    Report & Remediate

    Clear, prioritized findings with proof, a remediation roadmap, and a free retest to confirm the fixes hold.
