Important Highlights from this Release


  • For the FedRamp site, the Resource Center ? icon (in the upper-right corner of the page, next to Quick Actions) now correctly links to the Documentation site.

  • A new Tenable.io widget for the Microsoft Exchange Server ProxyLogon/Hafnium vulnerability. The new widget will be part of the Vulnerability Management Overview dashboard and the widget library.

Tenable released plugins for Microsoft Exchange Servers which can be used to determine which systems are vulnerable in the environment.
