- Install Certify The Web on the server you would like SSL on.
- Go through the guide when it opens, use a real email address.
- New Certificate

We'll set the SSL renew for 14 days before it expires and the also set PRTG to alert us if the certificate get's below 13 days. This should be a great solution and we'll know if it's ever not working with PRTG monitoring it.
