The ease of use and flexibility of configuration are great features of this software. It's also very robust and reliable. I like how it can be used as a standalone authentication server or within a multi-factor system. Easy integration with other products such as ADFS. I also love that it includes an enterprise grade certificate management service which makes it easy to manage certificates. The price tag is a little high for some clients but overall it has been a good product. We have been able to deploy two factor authentication to our customers without requiring them to purchase any additional hardware. This has reduced fraud significantly while giving our customers confidence that their information is protected.
