I like that they do an excellent job at keeping my site secure while also providing great reporting features to help me monitor what is happening in my environment.
There are some areas where their UI could be improved but overall it's been fairly easy for our team to get up to speed using this tool. We have not found any other software of similar nature as far as security scanning goes. It has really helped us identify potential threats within our application which would otherwise go unnoticed by our users and customers.
