Sign up for a Trial License of the CheckTLS Outlook Add-in ("CsOA") by filling in this screen.

A Trial License lets you install and use CsOA on a single PC. The installation process, and how the Add-in works, are the same as a Full CsOA License.

A Full License uses public/private key pairs to authorize access to CsOA, while the Trial License uses a unique GUID to authorize your PC.

The GUID is a one-way hash of your Windows USERNAME and COMPUTERNAME. We do not keep your USERNAME or COMPUTERNAME.


When you click Save below, your Trial License will be enabled and you will be redirected to this More Info page where you can install the Add-in.
