What's New

  • Support for launching basic network Nessus scan - PVS 4.4.0 provides the ability to launch an active basic network Nessus scan on hosts monitored by PVS. This feature integrates with Nessus 6.4 or above, as it requires API keys.
  • New results views and charts for Mobile devices - New Mobile results views have been added to the user interface that provide visibility into mobile devices discovered and their attributes such as device model and operating system, their vulnerabilities and applications discovered running on them. A few distribution charts by device model, operating system and mobile applications have also been added.

The ability to view the hostname in the user interface will be available in a future release.
