This article lists the certificates used in OfficeScan XG/Apex One.
For the OfficeScan server and client machines which do not have these certificates, the following issues may occur:
- OfficeScan clients remain in "Updating" state and fail to get their updates from the server
- OfficeScan server cannot verify the agents' digital signatures during Inter-Process Communication (IPC)
These issues occur when OfficeScan 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:

- Make sure that the value is set to "Not configured" (default value).
