PlaxidityX CAN Protection is an automotive-grade Intrusion Detection and Prevention System (IDPS) designed specifically for Controller Area Network (CAN) bus networks in vehicles. The solution provides real-time monitoring, detection, and prevention of cyber threats and anomalies on the CAN bus, which is critical for safety-related vehicle systems. It inspects all types of CAN messages—including communication, diagnostics, and control frames—to identify irregularities in message periodicity, protocol control information, and payloads. The system detects and blocks common attack methods such as denial of service, brute force, and unauthorized diagnostic access, and reports suspicious activities as security events. CAN Protection is hardware-agnostic, supports Classic AUTOSAR architectures, and is validated for integration with leading automotive software stacks. It is engineered for minimal impact on memory, CPU, and network latency, making it suitable for both prototype and series production environments. The solution helps OEMs and suppliers meet regulatory requirements such as UNECE R155 and ASPICE 3.1, and reduces the risk of costly recalls and brand damage due to cyber incidents.
