I'm able to leverage other open source tools for various tasks such as scanning, reporting, etc. The UI is simple but functional. They have some features that are useful especially when dealing with multiple hosts in one scan (e.g., hostname lookups). It also allows me keep track of my scans from different areas. There seems to be an issue where you cannot do cross-scanner queries like you can if using 3rd party tool - so you must combine your work into 1 scanner which sucks! We use CentralEye together with VulnChecker and it works great! This gives us fast alerts about vulnerabilities that need attention. The most important thing I like about this software is that it helps me get an overview of my network, and gives me a good idea of how vulnerable I am. It's also very easy to use. There are many features that can be used to customize your own needs. I think that the price could be lower, but for now, I don't have any complaints. If you want to know more about your network, then this is the right tool for you. I have been able to find vulnerabilities in my network.
