Trellix On-Prem ePO Common Catalog Removal
In Skyhigh Client Proxy 4.9.1 and later, the dependency of Common Catalog Extension has been removed, providing users with a seamless experience when updating the Bypass List and Alternate Redirection List elements. For more details on how to remove it, see On-Prem ePO Common Catalog Removal.
IMPORTANT: It is required to follow the correct Common Catalog removal steps after completing the upgrade of the SCP extension to 4.9.1 or later to avoid any compatibility issues in the future with Trellix On-prem ePO.
Enhancements
Simplified Steps for Configuring PA-UDP
Support for the UDP protocol for Private Access has been improved through simplified steps for configuring PA-UDP settings. For more details, see Prerequisites and Firewall Settings for Private Applications.
Clear Text Log Optimization
Clear Text Logs are optimized by removing lines that are printed continuously, as they increase the log size and affect readability along with changing some of the ERROR Logs labels to INFO or WARNING on Windows & macOS.
Support for UDP-based Private Applications on macOS
Skyhigh Client Proxy supports UDP traffic for private applications using Private Access on macOS.

Known Issues
Reference | Issue Description |
---|---|
MCP-6590 | Issue: Policy Revision Number Mismatch between Trellix SaaS EPO and SCP Client (Mac and Windows). which happens only in a specific user environment. Workaround: Only the Trellix Saas ePO would show a rev no. of (N+1), compared with the endpoint. All the functionalities will be working as it is. |
MCP-6658 | Issue: Trellix SaaS ePO: In some scenarios when Bypass list and Alternate Redirection list settings are added/modified (eg. Domain Name, Network Address, Port and Process list information) the settings do not remain saved, when we switch between tabs or navigate to another screen before saving the policy. Workaround: Before switching tabs, save the policy. |
MCP-6668 | Issue: If we apply a dummy proxy as primary, scp blocks/bypasses the alternate redirection traffic as well since the primary proxy is not reachable. |
MCP-6755 | Issue: If a policy name is updated from the Policy Catalog page, the revision number will not increase. Workaround: Open the policy and save it to get the updated policy name reflected in an endpoint |
MCP-6759 | Issue: When SCP is installed, it is unable to use a T-Mobile iPhone hotspot. This is only for Mac and IPv6 networks. |
