BloxOne is for DNS protection. We point our local domain name servers to it and it has a feed for "bad character" domain names. We protect our end-users that way. The way we're using it, that's all it does. It fits in somewhere in the middle of our security stack. DNS is the most important part of networking. Not so many people see it that way, but if you can't resolve, say, "cnn.com", nothing works. If your DNS doesn't work correctly, nothing is going to work correctly on your network. It is one of the first layers that comes into play when going to a website or using email.
It's a SaaS solution, a service that InfoBlox provides. All the systems are run by them and they maintain it.
