Network Gateways

Description

A Network Gateway is a hardware or software device that acts as a bridge between two different networks, enabling communication and data exchange. It translates protocols, manages traffic, and provides security while connecting devices across local, wide-area, or cloud networks. In industrial automation, IoT, and enterprise IT systems, gateways play a vital role in ensuring seamless connectivity, data management, and system integration.
