This tool allows you to test the HTTPS security of any website by analyzing security headers, certificate validity, mixed content detection, and secure connection requirements. Simply enter a website URL to check its security configuration.

What is HTTPS Everywhere?

HTTPS Everywhere is a security feature that ensures websites use encrypted HTTPS connections instead of insecure HTTP. It automatically redirects HTTP requests to HTTPS and blocks mixed content that could compromise security.

Why HTTPS Matters

• Encrypts data between your browser and websites
• Prevents man-in-the-middle attacks
• Protects your privacy and sensitive information
• Ensures website authenticity and integrity
• Required for many modern web features

The HTTPS Everywhere Checker uses multiple testing methods including security header analysis, certificate validation, mixed content detection, HSTS testing, and secure connection verification to assess website security.

The tool tests for various security headers including HSTS, CSP, and other security-related headers that enhance HTTPS security.

Security Headers Tested

• HSTS (HTTP Strict Transport Security): Forces HTTPS connections
• CSP (Content Security Policy): Prevents XSS and injection attacks
• X-Frame-Options: Prevents clickjacking attacks
• X-Content-Type-Options: Prevents MIME type sniffing
• Referrer-Policy: Controls referrer information
