Description of ES Direct protocol
Article ID: KB417 email a link to this article

What is ES Direct?

ES Direct is a protocol for use over a local area network (LAN) whereby the ESET Endpoint Encryption (EEE) Client can locate the EEE Server, and then open an encrypted direct communication to perform various commands.

ES Direct uses a single UDP/TCP port. The UDP port will accept an IP multicast packet meaning the client does not necessarily need to be configured with the server address and the server can be assigned a dynamic address. However, if the network topology does not allow the transmission of multicast packets then the client can be configured with the server address.

The port can be configured in the EEE Server control panel under the organisation settings tab.

What features are supported?

Auto Enrolment

The new Self Enrolment feature provides automatic activation for systems that are on the same local network as the EEE Server. When a user logs into their domain account, the EEE Server is contacted and the EEE client is automatically provided with the user’s key-file and activation information.

This provides a seamless experience for the user, especially when roaming, as a user is able to log into a new workstation without needing to perform the traditional EEE activation.

Once Self Enrolment has been completed, the EEE Server and EEE client are able to communicate through the EEE Cloud Proxy in the usual way. Key-File updates, Full Disk Encryption and all the EEE functions continue to operate as normal.
