Problem Description
According to Trend Vision One™ Standard Endpoint Protection: New Web Browser Extension Support, the Trend Micro Toolbar for Enterprise browser extension is automatically downloaded and installed on supported endpoints when the "Check HTTPS URLs" option is enabled, starting from Apex One version 14.0.20315.
The Trend Micro extension may block extensions defined by Google Workspace due to a conflict between the ExtensionInstallForcelist registry key and cloud policy.
Based on the chrome://policy output on affected machines, the cloud source value is overwritten by the platform source value, which causes the conflict.
Scope of Impact
This issue occurs only in environments where Google Workspace administrators have defined custom extensions. Standard deployments without cloud policies are not affected.
Mitigation
The hotfix is available after installing the following versions:
- Standard Endpoint Protection (SEP) version: 14.0.0.20600
- XDR Endpoint Security (XES) version: 1.2.0.7218
To prevent conflicts, the browser extension force-install setting will be merged into the customer’s cloud policy.
- Open the Google Admin Console and add the Trend extension to the policy.
