# IsomerSSL 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](https://letsencrypt.org/). 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. {% hint style="info" %} **Wondering how our redirection service works?** You can read more here: {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
