Why SSL Certificates Matter

Frequently Asked Questions

What happens when an SSL certificate expires?

Browsers display security warnings and may block access. Users see "Not Secure" in the address bar. The site remains functional but loses user trust. Renew certificates before expiration.

How often should SSL certificates be renewed?

Most certificates are valid for 1 year. Plan renewal 30 days before expiration. Some organizations get 2 or 3-year certificates but must renew before expiry.

What's the difference between DV and EV certificates?

DV (Domain Validation) is quick and inexpensive. EV (Extended Validation) requires business verification and shows company name in browser. EV provides stronger trust signals.
