Do you know what happens between the last time a vulnerability scan is completed and the next time a new scan will be completed? New hosts, new ports, new services, and new vulnerabilities can arrive on your networks faster than you may be allowed to scan for them.

The Tenable Passive Vulnerability Scanner (PVS) can find out what is happening on your network without actively scanning it. Each PVS monitors your network for vulnerable systems, watches for potential application compromises, client and server trust relationships, and open or browsed network protocols in use.

A single PVS can be placed in front of a network of 25,000 systems and continuously monitor the traffic for a variety of security related information including:

• Keeping track of all client and server application vulnerabilities
• Detecting when an application is compromised or subverted
• Detecting which applications and servers host or transmit sensitive data
• Detecting when new hosts are added to the network
• Detecting when an internal system begins to port scan other systems
• Highlighting all interactive and encrypted network sessions
• Tracking exactly which systems communicate with other internal systems
• Detecting which ports are served and which ports are browsed for each individual system
• Passively determining the type of operating system of each active host

A PVS software license is priced on a per installation basis with no limitations on the number of hosts or size of network being monitored. For pricing and quotes, please contact our sales team.
