About SSL Certificates

What is an SSL Certificate?

SSL (Secure Sockets Layer) certificates are digital certificates that authenticate a website's identity and enable an encrypted connection between a web server and a browser.

Why Check SSL?

Regularly checking your SSL certificate helps ensure your website remains secure, prevents expired certificates, and maintains visitor trust and SEO rankings.

Certificate Expiration

SSL certificates typically last 1 year. It's important to renew them before expiration to avoid security warnings and maintain continuous protection.
