Tenable Network Security's Security Center includes a 3D visualization tool that can derive network topology information from distributed Nessus vulnerability scanners. Each node in the center helix of the above graph is detected router. Clicking on the router can expose the number of hosts "behind" each router. Placing your mouse over the node displays its vulnerabilities and placing your mouse over the router can display its links to other routers. The entire display can be rotated and loaded with different data sets. For example, a user could query the Security Center to get a list of all web servers, then perform a second query for all web servers which perhaps didn't have logging enabled and then display these locations on the topology. A video of the 3D tool in action is located here.
