As more and more devices come online and networks open to the internet to make operational and communication gains with IIoT based services, security has become paramount for ensuring that your network’s traffic stays between your devices, with network vulnerabilities including unauthorized data access and unauthorized network commands, risking loss of data and operational downtimes.

Featuring 6 x Gigabit RJ45 ports and the choice between 2 x Secure Gigabit RJ45 ports or 2 x Secure Gigabit SFP uplink slots, ATOP’s EHG2408 switch series provides a plug-and-play solution for fast, reliable network switching that offers increased network security through MACsec encryption.

Providing point-to-point security on Ethernet links between nodes, MACsec uses GCM-AES to ensure the integrity of all network traffic. This means it can secure a network from a whole host of security threats, including intrusion, man-in-the-middle, masquerading, passive wiretapping, and playback attacks. And because MACsec encryption is hardware-based, there is no added latency.

With its modern, slim, and  flat design to minimize surface area usage, the EHG2408 series is ideal for demanding industrial applications that require compact solutions while delivering high network performance. Supporting a wide operating temperature range of -20°C to 70°C and being compliant with essential sections of EN 60950, UL/IEC 60950, EN/IEC(CB)/UL62368-1, and MIL-STD-810G, the EHG2408 switch series is a powerful compact device that can perform under a variety of environmental conditions, such as power input voltage, shock, drop and vibration.
