What Hex-Five's MultiZone Security Can Do For You

Hardware-Grade Security

Formally verifiable, hardware-enforced software-defined trusted execution environments using standard RISC-V ISA. This enables complete isolation of programs and data between untrusted applications or exposed attack surfaces and safety-critical code segments.

Lightweight and Fast

Consumes less than 1KB of RAM and <1% of CPU. Supports ultrafast zone switching and preemtable user-mode interrupts. MultiZone Security is written entirely in assembly and has no dependencies on external libraries or runtimes.

Simple Integration

Requires no additional cores, specialized hardware or changes to existing code. With the policy-based configurator a system can be up and running with HexFive’s MultiZone Security in minutes.

Why Hex Five?

MultiZone Security is the culmination of the embedded security best practices developed over the last decade and now applied to RISC-V processors. No more secure vs. not secure worlds: MultiZone Security provides policy-based hardware-enforced separation for an unlimited number of security domains, with full control over data, code and peripherals.

Contrary to traditional solutions, MultiZone Security requires no additional hardware, dedicated cores or clunky programming models. Open source libraries, third party binaries and legacy code can be configured in minutes to achieve unprecedented levels of safety and security.
