❓ FAQ

What is an SSL certificate?

An SSL certificate encrypts data between a website and its visitors. It's what puts the "S" in HTTPS and the padlock in your browser.

How often should I check my SSL?

Check at least monthly. Certificates expire and need renewal. Set a reminder 30 days before expiry to avoid downtime.

What happens when SSL expires?

Browsers show a security warning and visitors may be blocked from accessing your site. It can damage trust and SEO rankings.
