This article lists the certificates used in OfficeScan XG/Apex One.
For the product servers and client machines that do not have these certificates, the following issues may occur:
- Clients remain in "Updating" state and fail to get their updates from the server
- Server cannot verify the agents' digital signatures during Inter-Process Communication (IPC)
These issues occur when OfficeScan/Apex One is installed on a Windows machine without direct Internet connection for downloading certificate updates. These certificates are necessary on the endpoints, as well as the server itself.
To resolve this issue:
Download the root and intermediate certificates from the following links:
Certificates are free. If you encounter any issues, contact Trend Micro Technical Support.
