I will do web app penetration testing, OWASP audit, and fix xss, sql injection


Your website is only as strong as its weakest security gap.


Even a small vulnerability can let attackers:

  • Steal user or customer data
  • Inject malicious scripts into your pages
  • Deface your website
  • Compromise your database


I'm a CEH & CompTIA Security+ certified developer offering penetration testing, OWASP Top 10 vulnerability assessment, and hands-on fixes so your site works AND holds up under attack.


Whether your site was recently hacked or you just want to catch issues before an attacker does, I find the real problem and fix it at the root.


WHAT I FIX:

  • XSS (Cross-Site Scripting)
  • CSRF attacks
  • SQL Injection vulnerabilities
  • Broken authentication & session issues
  • Insecure APIs
  • Missing security headers
  • Exposed sensitive data
  • General bugs & broken functionality


WHAT YOU GET:

  • Full penetration testing & OWASP-based vulnerability assessment of your application
  • Detailed report with severity ratings
  • Issues fixed directly in your codebase
  • Secure authentication improvements
  • Best-practice recommendations to prevent future issues


Message me with your issue before ordering so I can scope it accurately.
