SSL Certificate Checker Expiry, Issuer & Coverage

Enter a domain to see its SSL certificate: who issued it, when it starts and expires, how many days are left, and which domain names it covers. Catch an expiring certificate before visitors see a scary browser warning.

What this tool checks

  • Certificate issuer and subject
  • Valid from and valid until dates
  • Days remaining before expiry
  • Domain names covered (SAN list)
  • Whether the certificate matches the domain

How to use it

  1. Enter your domain, for example yourhotel.com.
  2. Press Check SSL.
  3. If fewer than 30 days remain, renew the certificate now.

Why it matters for hotels, resorts and tour operators

An expired SSL certificate shows a full-page warning in most browsers. Visitors leave instantly, and booking forms stop working. For a hotel or tour operator, one expired certificate can mean lost bookings for days.

Most hosts renew certificates automatically, but renewals fail more often than people expect, especially after a hosting or DNS change. Check yours regularly.

Frequently asked questions

What happens when an SSL certificate expires?
Browsers warn visitors that the site is not secure, and many will refuse to load it. Forms and bookings can stop working.
How often should I check my SSL certificate?
Once a month is enough, and always after you change hosting or DNS.
Does SSL help SEO?
Yes. Google uses HTTPS as a ranking signal, and visitors trust secure sites more.
What does the SAN list mean?
It lists all the domain names the certificate protects. Make sure both the www and non-www versions are included.
Can you set up SSL for me?
Yes. We set up and monitor SSL as part of our website maintenance.
