Tenable has launched our Unified Security Monitoring (USM) concept. There is a new white paper available which details how event monitoring, vulnerability analysis and configuration auditing can all be leveraged in one process.
I realize this is a pretty advanced concept for some organizations, especially those that are large enough that their audit, incident response and patch management groups don't regularly communicate with one and other. Having said that, Tenable has many financial, government and academic customers where log analysis, configuration auditing, vulnerability monitoring and passive network monitoring are all performed by the same team. Accomplishing these tasks with not only the the same product suite, but also with the same core team has many political, efficiency and financial advantages.
I am also very excited to announce the launch of the merged Tenable and Nessus web sites. If you have not seen the new "unified" site yet, you'll notice the new Tenable company logo, and the new website design.
