To use the SSL Checker, simply enter your server's hostname (must be public) in the box below and click the Check SSL button. If you need an SSL certificate, check out the SSL Wizard.

How can SSL Shopper help you? We explain all the terms, give you certificate authority reviews from real customers, and let you compare every detail of each certificate so you can know you are making the best decision. Certificates are ranked according to what real customers have said about their providers.

Where should you get started? If you want to know about a particular certificate authority, start with the SSL Certificate Reviews. If you want a wizard to walk you through choosing an SSL certificate, compare SSL features from all providers with our SSL Wizard.

All the information on the site is kept as accurate as possible and the certificate authority reviews are unedited and posted by real customers so that it is easy to discern which provider will give you the greatest value.
