On a computer network, the term edge device refers to any apparatus that acts as an entry point into the core of the network. Examples include a router, a routing switch, a network multiplexer, or many of MAN and WAN access devices.

An edge device acts as a checkpoint at the border between two countries. When data attempts to enter the network, it is inspected according to certain security procedures, and either allowed or denied entry.
