Modern problems require modern solutions.
Craton Shield is a comprehensive family of memory-safe, #![no_std] Rust security modules designed to provide a unified defense-in-depth architecture for the most demanding embedded environments.
From IoT leaf nodes to complex automotive gateways and industrial controllers, Shield provides the primitives necessary to build secure-by-design systems. Each product builds on Shield Core — the open-source foundation providing CAN/Ethernet monitoring, basic crypto traits, tamper-evident logging, and an anomaly detection engine.
Shield Auto targets automotive ECUs with AUTOSAR Adaptive integration and V2X security. Shield Embedded delivers ultra-low-footprint security for IoT and wearables. Shield Industrial protects PLCs and SCADA systems with Modbus/OPC-UA/PROFINET IDS. Shield Enterprise adds HSM integration, post-quantum cryptography, and OTA orchestration for production-grade deployments.
All products share unified design principles: native bare-metal and RTOS compatibility, zero-allocation static memory, default-deny security posture, and predictable constant-time execution. CAN frame detection runs in under 500 ns on Cortex-M7 with zero jitter.
5 Products, 1 Unified Architecture
Shield Core (foundational IDS & crypto), Shield Auto (ISO 26262 / AUTOSAR), Shield Embedded (IoT / low-power), Shield Industrial (IEC 62443 / OT), and Shield Enterprise (HSM & post-quantum).
Memory-Safe by Construction
Written in 100% safe Rust (excluding minimal, audited FFI blocks). Zero-allocation, statically bounded data structures — no heap required. Eliminates 70% of the CVE classes that dominate embedded security bulletins.
Defense-in-Depth for Connected Systems
From IoT leaf nodes to automotive gateways and industrial controllers. CAN/Ethernet monitoring, tamper-evident logging, anomaly detection, V2X security, Modbus/OPC-UA/PROFINET IDS, and OTA orchestration.
The Technical Edge
Why experts choose Craton Shield
Modular Product Architecture
All products build on Shield Core (Apache-2.0). Specialized modules — Auto (ISO 26262), Embedded (ESP32/nRF52), Industrial (IEC 62443), Enterprise (BSL-1.1) — include only the crates necessary for each target platform.
Sub-Microsecond Deterministic IDS
CAN frame detection in under 500 ns on Cortex-M7. Zero jitter IDS engine with constant-time cryptographic verification. Scalable from constrained sensors to high-performance gateways.
Hybrid Licensing Model
Open source (Apache-2.0): Core, Auto, Embedded, and Industrial — fully transparent to drive industry-wide adoption. Commercial (BSL-1.1): Enterprise features, HSM integration, post-quantum crypto, and professional support.
