Super-Node

What is a Super Node?

A Super Node is a Windows device running a specially configured Endpoint Security Client with server-like and proxy capabilities. It functions as a light-weight proxy (based on NGINX) that helps reduce bandwidth consumption and supports offline updates, so that only the Super Node requires direct connectivity to the update servers.

By default, a Super Node listens on TCP port 4434 and TCP port 3128 (proxy mode) for client connections. Endpoint clients also use TCP port 4436 (HTTPS) for Super Node proximity calculations.

Note:

Ensure ports 4434 and 4436 are allowed between endpoints and the Super Node under the same firewall rules. If port 4436 is blocked, the Super Node cannot perform proximity calculations.

Primary Advantages:

  • Reduces site bandwidth usage.

  • Reduces server workload.

  • Reduces customer expense on server equipment, as there is no need for a local appliance.

  • Improved scale.

Note:

Super-Node is available in both Domain and Workgroup environments.
