PlaxidityX Ethernet Protection is an automotive-grade Intrusion Detection and Prevention System (IDPS) designed for in-vehicle Ethernet networks and switches. The solution provides real-time monitoring, detection, and prevention of cyber threats and anomalies on high-bandwidth automotive Ethernet backbones, which are increasingly used for advanced driver assistance, infotainment, and control systems. It inspects Ethernet traffic up to Layer 7, detects invalid or malicious activity, and enforces firewall rules based on vehicle system descriptions and automotive application protocols. The system is compliant with industry standards such as AUTOSAR firewall specifications and UNECE R155, and is ASPICE Level 2 certified with cybersecurity extensions. PlaxidityX Ethernet Protection can be integrated directly into automotive Ethernet switches, offloading security processing from microcontrollers and minimizing resource impact. It supports post-build configuration, standardized security event reporting, and is validated for integration with leading automotive software stacks and hardware platforms.
