I always used it with my customers because they needed monitoring but we also had some problems when was down or not working well sometimes (but there are good people from netrwix). There were many things like this happening every year since 2013 at least so don't expect too much help if you have something problem after upgrade/move your server etc.. Sometimes i got connection issues which made me annoyed, maybe just try different ports then see what works best? We use it as an application firewall solution mainly only using agentless mode - no other features yet. It helps us monitor our websites performance very easy way and even alert about possible attacks via email! It is very user-friendly and has a wide range of features for security assessments. I have only used a few of the features, but it is easy enough to learn. I would like to see more features, but I think the developers are working on it. We are able to assess the security of our network and identify areas that could be improved. We are also able to identify areas that are not secure enough and need to be addressed.
