Frequently Asked Questions

Find quick answers to common questions regarding SSL certificates and website security configuration.

An SSL certificate secures connection pathways between client browsers and server nodes by encrypting transit packets.

Security headers shield websites from common vulnerabilities like Cross-Site Scripting (XSS), Clickjacking, and cookie injection vectors.

The security grade is calculated by checking the presence of mandatory HTTP security headers (HSTS, CSP, X-Frame-Options) and verifying if the SSL certificate has more than 30 days remaining before expiration.

Generally, commercial certificates are valid for one year, while automated certificates (like Let's Encrypt) expire every 90 days.

TLS is the modern, secure successor of SSL. While the term SSL is still widely used, modern HTTPS sites use TLS.
