The security client on an endpoint needs to connect to various cloud services in order to download updates and implement protection features. Example services include the FLS (file look-up service), the Valkyrie file verdict service, and the website filtering service.
CCS can generate a diagnostic report on an endpoint’s connectivity with these services. This can help you troubleshoot issues you may be experiencing.
