Compare Belden Horizon Console vs. Karamba SafeCAN

Belden Horizon is an advanced software suite tailored for industrial use, aimed at delivering secure remote access, edge orchestration, and efficient management of operational-technology (OT) data for factories, plants, and critical infrastructure. Central to this solution is the Belden Horizon Console, which facilitates Secure Remote Access (SRA) and continuous, reliable connectivity through a Persistent Data Network (PDN), enabling technicians and service providers to connect securely to remote machines or networks for troubleshooting, maintenance, or monitoring without the need for complex IP routing or risking exposure of the entire network. The Horizon suite employs a robust zero-trust security framework, incorporating token-based two-factor authentication, role-based access controls for users and devices, encrypted communication tunnels, single sign-on capabilities through Active Directory, customizable password policies, IP address allow lists, and a unique “virtual Lockout-Tagout (vLOTO)” system for permissions, ensuring that connections to machinery are granted only after thorough security checks. By integrating these features, Belden Horizon not only enhances operational efficiency but also significantly mitigates risks associated with remote access to critical systems. This makes it an essential tool for modern industrial environments that prioritize both connectivity and security.

SafeCAN is a patented ultra-lightweight network security solution designed to authenticate and encrypt communications between electronic control units (ECUs) without introducing any network overhead. It ensures the integrity of the sender and the data for each message, effectively preventing unauthorized ECUs and physical tampering from compromising the system. Additionally, SafeCAN secures in-vehicle communications to thwart potential over-the-air (OTA) malware attacks. The innovative approach of SafeCAN allows for the exchange of encryption keys during the manufacturing process, eliminating the need for key swaps while the vehicle is operating, which is a common issue with other solutions. Unlike competing technologies that increase network traffic by sending extra validation messages, SafeCAN cleverly embeds validation information within the redundant bits of each message, thus avoiding additional payloads. Furthermore, its backward compatibility means there are no required modifications to the ECU application, network protocols, or chipset, making implementation smooth and straightforward. Its hardware-agnostic design ensures that it can be integrated without altering the existing message format, and importantly, it will not add strain to already congested vehicle networks while providing robust security. This makes SafeCAN an ideal choice for enhancing vehicle security without compromising performance.
