Overview

Nodes make up the strongDM network, and allow your users to connect securely to your resources. There are two types of nodes:

  1. Relay: creates connectivity to your datasources, while maintaining the egress-only nature of your firewall

  2. Gateways: a relay that also listens for connections from strongDM clients
