Main Menu Enhancements:

A few main menu items have been renamed and re-organized to make the menu more intuitive:

  • A new "Zero-Day Protection" menu item is now part of the "Monitor and Analyze" section that contains two tabs that were previously under the “Advanced threat” menu. The first tab provides a record of all files that have been analyzed by Threat Intelligence and Sandboxing in the SophosLabs Intelix Cloud.  The second tab provides settings for this analysis..
  • A new "Sophos Central" menu item is part of the “System" section that contains the settings for connecting the firewall to Sophos Central for Synchronized Security features and for Sophos Central Management and Reporting (including the new Central VPN Orchestration capability).
  • Other minor changes include the renaming of the “Advanced threat” menu item to “Advanced Protection” to better reflect it’s function
