Free tool

Free Let’s Encrypt certificates for IIS.

An expired certificate takes a site down and sends visitors a warning. CertBot is a free Windows app that gets Let’s Encrypt certificates for the sites on your IIS server and renews them automatically every day, so nobody has to remember.

Updates are free and arrive automatically from Rubix Hub.

What it does
