AM4-LD is a rugged, CAN-based cybersecurity gateway designed to protect traffic and devices across internal vehicle networks. Housed in a durable, industrial-grade enclosure, it is built to withstand the demands of heavy-duty trucking environments, making it ideal for mission-critical mobile applications. By isolating internal CAN buses from external service connectors, the gateway prevents unauthorized access from reaching digital devices inside the vehicle, offering a reliable and scalable layer of defense against cyberattacks.
