I will do web application penetration testing and owasp top 10 vulnerability assessment


About this gig
I will do web app penetration testing, full VAPT, and OWASP Top 10 vulnerability assessment
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 full VAPT (Vulnerability Assessment and Penetration Testing), OWASP Top 10 audits, and targeted 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 show you exactly where it lives with the option to have it patched too.
WHAT I TEST FOR:
- XSS (Cross-Site Scripting)
- CSRF attacks
- SQL Injection vulnerabilities
- Broken authentication & session handling
- Insecure APIs
- Missing security headers
- Exposed sensitive data
