Security Heartbeat on the Windows Update

Question

Good morning everyone, 
 Is it possible to use Security Heartbeat on computers that have Windows installed and are not updated via Windows Update? 
 I know and we have applied Security Heartbeat where the endpoint is not up to date restricts internet access (green, yellow or unrestricted). 
 I await comments or help on how to proceed with this.

Thank you for reaching us, It is not possible to use Heartbeat in an environment where internet access isn&rsquo;t allowed, as your endpoint will always get isolated once heartbeat is triggered due to an endpoint update issue. However, if you deploy the Message relay and update the cache server on this Isolated network and allow all endpoints on this network to update via this server, then it&rsquo;s possible. You may refer to this documentation on how update cache and message relay works
