Host Protection

Intrusion Detection and Prevention for ECUs

Argus’ ECU Intrusion Detection and Prevention System reduces risk and drives compliance with detection, protection, logging, and fail-safe capabilities for Posix based ECUs running Linux, Android and Adaptive AutoSAR software.

Autosar Firewall Protection Software
why now?

Detect and prevent intrusions within vehicle components

Built on widely available POSIX operating systems, core components such as infotainment, telemetry units, and driver assistance systems are exposed to a wide pool of potential increased risks. Vulnerability databases are freely available to malicious actors, and connections like Wi-Fi and Bluetooth provide an attack vector. As a result, manufacturers and suppliers need ECU protection tools which accommodate automotive-specific requirements, such as AUTOSAR cyber security.
