New features and improvements

• Online Safety alerts are added.
• Business Suite + EDR installation experience is now improved.
• WithSecure Firewall has a new feature to allow certain rules and groups of rules when "disable all rules" option is selected. It's useful if you want, for instance, to disable all rules except Network Discovery.
• User specific environment variables are now supported in Firewall.
• If Firewall option is unchecked from the installation wizard, even our built-in FW rules should not be added.
• Remove unnecessary built-in inbound Firewall rules.
• Enriched info for scanning alerts.
• Mailbox scanning feature analyzing OST/PST files for infection.

Limitations

• Before upgrading Client Security and Server Security on golden images and snapshots to this version please check that installed version of F-Secure Ultralight Updater update is 2023_05_08_01 or newer.
• After the Policy Manager upgrade to version 16.00, automatic Firewall rule for Policy Manager ports created by Server Security 14.10 and newer will stop functioning. You would need to create corresponding Firewall rule manually or upgrade Server Security to version 16.00 and install HF 16.00HF1 to allow external connections to Policy Manager ports.

Installation

• It is now required to have Policy Manager server address defined at the Root domain level. It is still possible to override values for subdomains, i.e. Policy Manager host has specific alias for certain location.
• It is now impossible to modify Policy Manager Server address in the Remote Installation Wizard. It should be defined in policies instead

A new version of the Ultralight Core update, part of the Windows endpoint client has been released on 3rd of July, WithSecure Ultralight Core 2024-06-24_01. 

With this release, we are removing the ORSP service (fsulorsp) and corresponding executables (fsorsp.exe / fsorsp64.exe). This should have no affect for customers, but any custom agent monitoring in place might be affected, as this change might break health checks.

Released for GA on 3rd of July 2024.
