Website Security Grader is a Python-based tool that analyzes the security posture of any website. It evaluates key parameters like HTTPS support, TLS configuration, SSL certificate, secure headers, secure cookies, and more — then assigns a Security Grade (A+ to D) based on industry-standard best practices.
👉 
- ✅ Check if the website uses HTTPS
- 🔒 Analyze TLS version (TLSv1.2, TLSv1.3, etc.)
- 📜 Inspect SSL/TLS Certificate details
- 📅 Validate Certificate expiration
- 🛡️ Detect HTTP Strict Transport Security (HSTS)
- 🔐 Check for Secure Cookies
- 📦 Inspect Security Headers:
X-Frame-OptionsX-Content-Type-OptionsX-XSS-Protection
- 🧠 Check for Content Security Policy (CSP)
- 📈 Assign final security grade (A+ to D)
