How I Built a Free Web Security Scanner That Uncovers 8+ Vulnerabilities in 30 Seconds

Web security is often treated as an afterthought — until something goes wrong. As a developer who's spent years building and breaking web apps, I decided to change that.

The Problem

Every day, thousands of websites go live without basic security protections:

• Missing security headers (HSTS, CSP, X-Frame-Options)
• Open ports exposing attack surfaces
• CORS misconfigurations leaking sensitive data
• SSL/TLS weaknesses making MITM attacks trivial

Most developers either ignore these issues or can't afford expensive enterprise scanners.

The Solution: WebSec Scanner Pro

I built WebSec Scanner Pro — a comprehensive vulnerability scanner designed for real developers.

What It Checks

• ✅ OWASP Top 10 vulnerabilities — SQLi, XSS, CSRF, and more
• ✅ Security headers — HSTS, CSP, X-Frame-Options, etc.
• ✅ CORS configuration — checks for dangerous wildcard origins
• ✅ SSL/TLS validation — certificate issues
• ✅ Port scanning — identifies unnecessary open ports
• ✅ Information disclosure — directory listing, sensitive files
