IsomerSSL provisions SSL certificates for your sites. The certificates are issued by Let's Encrypt, a non-profit certificate authority run by Internet Security Research Group that provides X.509 certificates for Transport Layer Security encryption at no charge. You can read more about them here.
The certs are provisioned through CertBot, which is integrated into Isomer's redirection server.
To use this IsomerSSL, all you need to do is to point your A-record to our redirection server and we'll provision a cert for you.
Certificate renewal typically happens every 3 months and it will be handled by Isomer team centrally.
