About SSL Certificates

What is an SSL Certificate?

An SSL (Secure Sockets Layer) certificate is a digital certificate that authenticates a website's identity and enables an encrypted connection.

Why Check Expiry?

An expired SSL certificate will cause browsers to display security warnings, eroding user trust and potentially disrupting service.

Secure Connection

SSL is essential for protecting sensitive information like login credentials, credit card numbers, and personal data from being intercepted.

HTTPS and SEO

Websites with active SSL certificates (using HTTPS) are often favored by search engines, which can positively impact search rankings.
