EDR Core (Total Security Suite) Release Notes

New Features

• In WatchGuard Patch Management, you can now configure computers on the network as test computers. Use test computers to verify patches install successfully before you deploy the patches across the network.
  • You can also configure computers or computer groups to not install patches.
  • When you create a patch installation task, you can select to install patches on only test computers.

Enhancements

• In the Patch Management Installation History list, when a patch requires a computer restart, the patch status shows as Pending Restart. The status now changes to Installed when the computer restarts and completes patch installation.
• The default workstations and servers settings profile now has anti-exploit and decoy files disabled. Endpoint Security applies this profile to the All group by default until you create and assign a new profile. This profile helps prevent issues with third-party antivirus and EDR solutions when you activate the Endpoint Risk Assessment. This change does not affect Endpoint Risk Assessments in progress.
• When an Endpoint Risk Assessment is in progress, and you want to schedule a report, the Risk Assessment Report is now selected by default.
• Subscriber accounts with EDR Core allocated to their endpoints, but not deployed, can now start a trial of WatchGuard EPDR or Advanced EPDR and activate an Endpoint Risk Assessment.
• You can now download signature files over HTTPS.

Resolved Issues

• When the user is not logged in to the endpoint, WatchGuard Endpoint Security can now re-install with a restart after the scheduled wait time is exceeded.
• Duplicate computers no longer display when you use Active Directory to discover unmanaged computers.
• When you filter the Unmanaged Computers Discovered list and then select all filtered computers to install WatchGuard Endpoint Security on, the software now installs only on the computers in the filtered list.
• A fix was made to make sure that WatchGuard Endpoint Security sends executive reports and other scheduled daily reports as expected.
• When you disable a feature that uses the NAHSL network driver (for example, Advanced Protection, Web Access Control, or the Firewall), the NAHSL network driver is disabled.

Enhancements

• These enhancements were made in Windows protection v8.00.22.0024 and higher:
  • The software upgrade process was enhanced to make sure that Windows devices do not receive a BSOD error when EDR Core cannot stop a driver.
  • Improvements were made to prevent high CPU usage during computer startup when the Shadow Copies feature is enabled.

Resolved Issues

• These issues were resolved in Windows protection v8.00.22.0024 and higher:
  • A fix was made to prevent memory leaks on connections over port 8180 of the Java application that could cause the server to run out of memory.
  • The URL filtering feature prevents access to URLs configured as denied (for example, Facebook or YouTube pages).
  • A fix was made to prevent a rare BSOD error caused by the pskmad.sys driver.
  • The AMSI detection technology now respects the path exclusions configured in the protection software settings.

Resolved Issues

• Fixed a vulnerability in the pskmad_64.sys driver that could enable an attacker with Administrator privileges to run code with SYSTEM privileges on the target computer. For more information, review this Security Advisory Detail. This fix requires Windows protection version 8.00.22.0023 or higher.

Enhancements

• You can now isolate Mac computers on your network. Similar to the Windows feature, isolated Mac computers allow only WatchGuard Endpoint Security processes to communicate. If an attack occurs, you can isolate the computer from the network to prevent the spread of the threat. If required, you can exclude other processes to allow them to communicate on isolated computers. This feature requires macOS protection version 3.04.00.0000 or higher.
• To improve anti-tamper protection, you can now require two-factor authentication (2FA) when users try to log in to the management UI from their computers or uninstall the WatchGuard Endpoint Security product from their computer. 2FA uses a QR code you can generate for all computers in a customer account or, if you want to have different authenticator factors for different settings profiles, you can generate multiple QR codes. This feature requires Windows protection version 8.00.22.0023 or higher.
• Anti-tampering features now protect Windows computers when they start in Safe Mode. This setting is enabled by default. You can disable it in the management UI or from the Windows computer. This feature requires Windows protection version 8.00.22.0023 or higher.
• In the list of discovered computers, you can now select all unprotected computers.

Resolved Issues

• When a MAC address is not in uppercase letters, the security software can still discover unprotected computers.
• When you search the network for unprotected computers, the search results do not return protected computers that do not match the name in the list.
• Resolved an issue to make sure that antivirus exclusions are applied to decoy files. This fix requires Windows protection version 8.00.22.0023 or higher.
• Resolved an issue that caused a rare BSOD error when the server generated malformed network packages. This fix requires Windows protection version 8.00.22.0023 or higher.
• The zlib version was updated to resolve vulnerabilities in the previous version. This fix requires Windows protection version 8.00.22.0023 or higher.
• Performance improvements on virtual servers. This fix requires Windows protection version 8.00.22.0023 or higher.

Resolved Issues

• An updated version of the macOS protection (v3.03.00.0003) is now available. The updated version includes these resolved issues: 
  • Network access enforcement (VPN enforcement) now works for endpoints with macOS v3.03.00.0003 and higher. [WGUA-1913]
  • The network extension no longer stops working and the message that NeXT privileges had not been accepted no longer appears. [WGUA-2048]
  • When analyzing paths and files that contain special characters or emojis, the local console no longer stops working. [WGUA-2119]
  • macOS v3.03.00.0003 includes performance improvements. Goodware items are now correctly added to the cache to optimize the analysis at the next program execution. [WGUA-1629]
