The best thing that I liked is its integration into my Plesk interface which makes managing it easy for me as well has giving us many options such like caching proxy servers or other features provided via this software package are quite amazing! What i did not really enjoy was when we had issues regarding our license key but their support team helped out very quickly solving those minor problems even without any downtime at all!! So far everything's been good apart from some little bugs here-and there nothing serious enough though they were solved fastly so no worries about security concerns since they have great customer service available through livechat feature too.
