What's New

10Gbps Support for Virtual/Software deployments (Non Tenable Appliance)

PVS version 4.2.1 provides capabilities for real-time multi-gigabit network traffic monitoring for software-based installs either with bare-metal installs of RHEL 6 or running under VMware ESX/ESXi 5.5.

ERSPAN Encapsulation Support

In addition to Generic IP Encapsulation, added support for VMware ERSPAN (Transparent Ethernet Bridging) and Cisco ERSPAN (ERSPAN Type II). ERSPAN allows you to mirror traffic from one or more "source" ports on a virtual switch or even a physical switch or router and send the traffic to a "destination IP" host running PVS. This could help in situations were provisioning a span port or network tap is problematic. More general info on ERSPAN:

Red Hat 7 Support for standard mode (non 10Gb)

Standard mode PVS is now supported on RHEL 7. High speed (10G mode) will be supported in a future release.

License enforce throughput by entitlement ("Standard mode" vs 10G "High speed mode")

High speed (10G mode) is now enforced via activation code. SC-CV includes unlimited "standard mode" PVS but each 10G sensor will need a dedicated activation code.

Additional Improvements

  • Realtime session logging has been updated to included total bytes transferred and session duration.
  • Prevent interfaces that have IP addresses bound to them from being selected in high performance mode.
  • Upgraded SQLite to
  • Upgraded OpenSSL to 1.0.0r.
