If you have a large network, the Security Center can be used to place multiple Nessus scanners throughout your infrastructure. Using multiple scanners decreases your scan time, but also has several other advantages.
The Security Center can help any organization meet their compliance reporting needs. Having the Security Center in use makes it very easy to demonstrate vulnerability management, incident response and asset discovery functions.
With the Tenable Security Center, you can combine the knowledge of existing asset inventories with the vulnerability and compliance information discovered by Nessus and the Passive Vulnerability Scanner.
