Industrial Automation and Control Systems (IACS): Securing Critical Infrastructure with Certified Cryptography
Robust, certifiable security solutions for next-generation industrial control systems
Industrial Automation and Control Systems (IACS) form the backbone of modern manufacturing, utilities, and infrastructure. From SCADA controllers and industrial drives to proprietary fieldbus networks and human-machine interfaces, these systems operate under stringent safety and cybersecurity requirements. FortifyIQ provides hardened cryptographic hardware and software solutions that deliver certified resistance to sophisticated physical attacks, enabling SoC designers, system integrators, and security leaders to meet evolving regulatory demands without compromising performance or reliability.
The IACS Security Challenge
Long Equipment Lifecycles & Legacy Deployments
Many industrial control devices remain in operation for decades, often lacking hardware cryptographic protections but facing modern security standards.
Compliance & Audit Readiness
Regulations like IEC 62443, NIST SP 800-82, and the EU NIS2 Directive demand proven, certifiable cryptographic modules with documented security lifecycles.
Diverse & Interconnected Environments
Expanding connectivity between operational technology (OT) and IT increases exposure to cyber-physical threats, including side-channel and fault-injection attacks (SCA/FIA).
Operational Safety & Performance
Security solutions must operate deterministically with minimal latency and resource overhead, ensuring no disruption to critical control loops.
Why FortifyIQ ?
Industrial control systems must stay secure for decades, often on legacy, resource-limited devices, while meeting strict OT/IT and regulatory requirements. FortifyIQ provides certified, modular cryptography, such as hardware IP, software libraries, and Roots of Trust, designed to protect legacy and modern systems alike. Our technology-agnostic, high-efficiency solutions ensure secure communications, firmware integrity, and lifecycle protection, with post-quantum readiness for the long term.
Optimized for Industrial Use Cases — Hardware IP cores and software crypto libraries with exceptional power, performance, and area (PPA), designed to run efficiently on constrained MCUs, MPUs, and custom SoCs used in SCADA, industrial drives, and fieldbus interfaces.
Modular Cryptobox and Root-of-Trust IPs — Combining AES, PKA (ECC/RSA), PQC, and HMAC-SHA2, customizable to your application’s needs for secure boot, firmware authentication, encrypted communications, and device lifecycle security.
Technology-and Platform-agnostic, Integration-ready — Our algorithmic cryptographic protection applies equally in any silicon process or system architecture. Delivered as synthesizable soft macros, FortifyIQ’s cryptographic IP is technology-neutral and integrates seamlessly into industrial ASICs, FPGAs, and legacy SoCs, with no need for proprietary instructions or hardware changes.
Quantum-era Readiness for Long-lived Infrastructure — FortifyIQ offers SCA/FIA-resistant post-quantum cryptography (ML-KEM, ML-DSA), ensuring long-term protection for industrial systems with decades-long deployment cycles.
Field Upgradeable Security — Our software libraries support over-the-air (OTA) updates, enabling legacy equipment to be retrofitted with certified cryptographic protection, extending device lifetime and compliance readiness.
