The Cyber Escort Unit is a hardware security IP (intellectual property) component designed to bridge the gap between software cybersecurity and hardware security. The product monitors program execution step-by-step to detect and prevent cyberattacks in real-time, including zero-day attacks. The technology operates at the hardware level, making it inaccessible to remote attackers. It provides protection against both software-based attacks (code injection, buffer overflow, stack smashing, control flow graph hijacking, return-oriented programming) and hardware-based fault injection attacks (temperature, electromagnetic injection, clock glitch, power glitch, laser injection). The Cyber Escort Unit functions without requiring processor modifications or program recompilation. It monitors fundamental properties of well-behaved code to limit false positive alarms. The product detects return address corruption on the stack and can stop attacks before execution. Runtime performance impact is minimal, typically less than 1% in most cases, with a low hardware footprint. The technology is processor-agnostic and does not influence the protected program. In safety contexts, it can restore the program counter to return the system to a stable state. Target markets include automotive (real-time, low latency, safety-compatible applications), SCADA systems, datacenters, network and telecom infrastructures, and government/defense sectors.
