SSL API use case

Online security is becoming tremendously important every single passing day. If commerce and businesses are going online, we can’t transfer the locks and alarm systems they have in their brick and mortar stores. We have to create new technologies that do that.

With our SSL API you can check the certificates of any domain name in the world and see it’s expiry date. Either offer your clients the installation of a certificate, or alert them in time when it’s time to renew or switch to another provider!
