It has helped me to identify vulnerabilities in my network, as well as fix them with ease. I am able to set up alerts for patches that are due or overdue so it's easy to keep track of what needs attention. There isn't anything about DS that I dislike. The only thing is that there aren't too many options for customization, but other than this everything works great! We use dark sight primarily for vulnerability assessments, patch management, server monitoring etc., but we also use it for managing our firewall rules. In addition, I have been using it for some time now to monitor servers for health purposes (CPU usage, Disk Space Usage).
