GuardKnox and CAROTA have partnered to provide a secure end-to-end solution for Over-The-Air (OTA) updates, remote diagnostic and cyber security (equipped with the patented Communication Lockdown™ methodology.) for the VSOC, Vehicle Security Operation Center.


The high performance, consolidated, customizable, secure solution will analyze in-vehicle data and will send security related data back to the VSOC.

CAROTA, a pioneer in the latest technologies is committed to serving the car networking ecosystem that enables this end-to-end solution for OEMs and Tier 1 suppliers.

The scalable solution can be implemented on any ECU and secures the communication in the vehicle as well as on the cloud.






One of the main benefits of digitalization is the capability to make functionality much more dynamic and allow for continuous customization of vehicle functions, thus greatly enhancing both the driver and passenger experience. In order to support such dynamic functionality, implemented in the form of services, vehicle ECUs need to be designed as secure, flexible, Service Oriented Architecture (SOA) ECUs. Such design shall allow OTA updates while providing a secure infrastructure to do so.


Such a flexible and open architecture requires stringent and advanced security protocols to ensure that any malicious code isn’t able to affect the overall system and other services. As the number of services, and service vendors grows, also is the task of making sure that all services are inherently secure. Thus, the underlying software and hardware infrastructure must ensure secure separation and compartmentation of resources and data between the services. Moreover, strict access control to services and data must be enforced.
