Unique Solution

Cyber Security Hardware

GuardKnox Secure Network Orchstrator (SNO) is a highly secure centralized ECU which provides high assurance defense for vehicle networks. Our patent pending technology serves as a centralized cyber security platform within the vehicle, providing security services to all ECUs in the vehicle. This leads to consolidation, lower complexity, easier certification and overall cost reduction. GuardKnox local ECU protection (Local SNO), provides an easy to integrate (drop-in) cyber security hardware solution, specifically designed for Infotainment, Telematics and other ECU’s with external communication, preventing the car from being hacked remotely and thus providing a security in depth approach.

Certified Safe and Secure

GuardKnox’s hardware solution is the only one which is completely autonomous, doesn’t require any external connectivity nor any updates, and can defend against any type of known or unknown cyber-attacks. It adheres to the most stringent security (ISO 15408) and safety (ISO 26262) standards. As a complete ECU, it integrates seamlessly into the vehicle, into the value chain and vehicle production process. By design, it is completely transparent to all other ECUs and doesn’t require any architectural modification, significantly lowering integration costs.

Fits Automotive Value Chain

There are approximately 100,000,000 vehicles manufactured annually and many more which are already on the road without cyber protection. GuardKnox’s architecture supports all automotive protocols, thus making it suitable for all vehicles, new and already on the road. GuardKnox’s unique value proposition brings to automotive manufacturers a solution that can be used in existing vehicles as a drop in replacement, allowing them to add robust security in a cost effective manner.

Key Competitive Advantages
