i like is ease of use, as well has being able to generate certificates in less than 2 minutes! I dislike how complicated it can be sometimes for someone who dont have any technical knowledge or experience using this software; that's why we also need an assistance from our IT Department whenever something goes wrong with someones certificate (like renewing them).
We are solving problems related security issues by generating unique SSL / TLS Certificates every time somebody needs one - especially when working remotely where you cannot rely completely into your network infrastructure but still having trusty connections between two different sites/clouds etc.
