HTTPS/TLS Security Analysis

Our checker evaluates your website's security configuration to ensure it follows modern web security standards and best practices.

  • HTTPS Implementation:
    We verify your website uses secure HTTPS protocol rather than insecure HTTP.
  • Certificate Validation:
    We check if your SSL/TLS certificate is valid, not expired, and properly matches your domain name.
  • Security Headers:
    We analyze implementation of critical security headers like HSTS.
  • Protocol Support:
    We test for modern protocol support such as HTTP/2 and secure TLS versions.

Based on these findings, you can enhance your website's security posture, protect user data, and improve search engine rankings.

HTTPS/TLS Security Best Practices​

❌ Bad Practice​

# Using HTTP instead of HTTPS
http://example.com

# Supporting outdated, insecure TLS versions
TLS 1.0: Enabled
TLS 1.1: Enabled

# Missing HSTS header
# (No Strict-Transport-Security header in response)

# Certificate issues
- Self-signed certificates
- Expired certificates
- Certificate with mismatched domain name
- Certificates using outdated encryption (SHA-1)
- Wildcard certificates used inappropriately

# HTTP/2 not supported
(Falling back to HTTP/1.1, reducing page load performance)

# Mixed content
- Loading scripts over HTTP on HTTPS pages
- Including insecure resources on secure pages

✅ Good Practice​

# Using secure HTTPS by default
https://example.com

# All HTTP requests automatically redirected to HTTPS
301 Redirect: http:// → https://

# Strong HSTS implementation
Strict-Transport-Security: max-age=31536000; includeSubDomains; preload

# Modern, secure protocols
HTTP/2: Enabled
TLS 1.2: Enabled
TLS 1.3: Enabled
TLS 1.0/1.1: Disabled

# Proper certificate configuration
- Valid, trusted certificate authority
- Certificate matches domain name
- Extended Validation (EV) or Organization Validation (OV) for e-commerce
- Appropriate use of wildcard certificates
- Modern encryption (SHA-256)
- Adequate key length (2048+ bits)

# Secure cipher configuration
- Strong cipher suites prioritized
- Weak ciphers disabled
