About this gig
Are you confident your website and customer data are fully protected?
I provide forensic-grade web application security audits using automated AST code scanning and OWASP Top 10 standards. You will receive an actionable executive PDF report and precise surgical code fixes (git diff) with zero disruption to your production servers.
What I Analyze:
* Missing HTTP Defensive Headers (HSTS, CSP, X-Frame-Options, Referrer-Policy)
* DOM-Based Cross-Site Scripting (XSS) and Insecure Direct Object References
* Open Redirection and Cross-Origin Message flaws
* Hardcoded credentials, exposed API endpoints, and sensitive information leakage
* SSL/TLS strength and cryptographic posture
Deliverables:
- Bank-Grade Executive PDF Report with severity scoring (Critical, High, Medium, Low)
- Surgical git diff remediation patches ready for your developers
- Verification of compliance with GDPR Art. 32 and OWASP standards
