FortiClient to EMS - Block unauthorized machines

[bcotnam]

Hi,

We currently, have a Fortigate 60D at a remote site which all clients are using FortiClient connected to a EMS Server for VPN Access.

What we would like to do is have the Fortigate block internet access if the FortiClient wasn't installed on the client machine (laptop/desktop) and reporting to EMS.  This is to avoid unauthorized access to the network and only FortiClients reporting to EMS can get access.  We would like to receive an alert when an "unauthorized" machine connects to the network for example locally.  This is only a remote site and only clients checking into EMS should have access.

Is this possible and what would be the best approach to achieve this? 

Any help or suggestions in this matter would be very helpful.

Need any further information let me know.

Thanks,

Blair
