InduTUX OS

Industrial-Grade Linux OS for Connected Industrial Products

InduTUX OS™ is a Linux OS platform developed and maintained by L4B Software, intended for integration into connected industrial products. It provides a long-term, secure, and maintainable operating system foundation for PLCs, IIoT gateways, edge controllers, industrial robotics, and connected machinery operating under increasing regulatory and cybersecurity obligations.

As regulatory expectations tighten – with the EU Cyber Resilience Act (CRA) entering enforcement in 2026, IEC 62443 cybersecurity requirements becoming de facto market requirements, and NIS 2 obligations extending across supply chains – industrial OEMs are required to manage SBOMs, vulnerability monitoring, secure update lifecycles, and long-term software maintenance. Building and sustaining this infrastructure internally requires significant ongoing investment in DevSecOps, cybersecurity engineering, and compliance processes most industrial engineering teams were never staffed to handle.

InduTUX OS goes beyond a standard Linux distribution. It is a managed platform service that delivers curated Linux builds, platform-level software lifecycle artifacts aligned with IEC 62443, cybersecurity engineering support, automated SBOM generation, CVE monitoring, and long-term update maintenance. InduTUX is designed to help industrial OEMs reduce operational burden and regulatory friction while retaining full system-level responsibility and control.

No separate real-time co-processor required. No split software architecture to maintain.
7. Future-Ready with Edge AI/ML: As industrial systems move toward smart automation and AI-driven control, InduTUX is ready to integrate AI/ML application layers – from vision systems to predictive maintenance – on the same secure, maintained OS foundation.

Standards & Regulatory Alignment

InduTUX OS is developed and maintained by L4B Software and is intended for integration into connected industrial products.

InduTUX supports industrial OEMs by aligning platform development, cybersecurity engineering, and lifecycle activities with relevant EU and international standards and regulations, including:

• EU Cyber Resilience Act (CRA) — Regulation 2024/2847 – Supporting SBOM generation, vulnerability monitoring, coordinated disclosure (ENISA reporting), and secure update lifecycle management
• IEC 62443-4-1 – Secure product development lifecycle: threat modeling, secure coding practices, security testing, and vulnerability management processes
• IEC 62443-4-2 – Technical security requirements for industrial control system components: secure boot, mandatory access control, audit logging, encrypted storage, and OTA update integrity
• IEC 61508 (SIL) – InduTUX is designed for integration into connected industrial products. For customers requiring IEC 61508 functional safety support – including pre-existing software evidence and SIL-compliant documentation – contact L4B to discuss your specific safety requirements.

InduTUX provides platform-level documentation, evidence, and cybersecurity support to assist OEM compliance efforts. Final system integration, risk acceptance, and regulatory compliance remain the responsibility of the industrial product manufacturer.

In addition, InduTUX supports industrial OEMs in addressing further applicable regulations, including:

• NIS 2 Directive – Supply chain cybersecurity obligations for manufacturers supplying operators of essential services across energy, manufacturing, transport, and healthcare
• ETSI EN 303 645 – Cybersecurity baseline for IoT consumer and industrial connected devices, relevant for CE marking under RED and CRA

Why Should You Build with InduTUX OS™?

Navigating the complexities of Linux in regulated industrial environments is not a simple task. It’s not just about picking a Linux distribution; it’s about understanding its security implications, ensuring ongoing CRA compliance, and maintaining it over a 10–15 year product life against constant vulnerability disclosures and evolving EU regulation.

With InduTUX OS™ by L4B, you’re not just purchasing a Linux subscription; you’re investing in:

• CRA Compliance Readiness: InduTUX is built around the CRA’s core obligations – SBOM, CVE monitoring, coordinated vulnerability disclosure, and secure update lifecycle. We provide the documented evidence the regulation requires before it becomes mandatory. Our engineering team is the same team that delivers MediTUX to regulated medical device manufacturers worldwide – industrial compliance is well within our scope.
• Commitment to Cybersecurity: Our cybersecurity engineering practices are informed by IEC 62443-4-1, IEC 62443-4-2, ETSI EN 303 645, and NIS 2. InduTUX delivers a hardened baseline – secure boot, mandatory access control, encrypted storage, and audit logging – as standard, not an add-on.
• 20+ Years of Proven Safety-Critical Software Delivery – Including Real-Time: Our legacy spans over 20 years of industrial and safety-critical embedded Linux projects, including deterministic real-time systems for motor control, robotics, and industrial Ethernet. The same engineering team that builds MediTUX for regulated medical devices brings that full-stack expertise — real-time, secure, and maintained – to industrial.
• Cost-Effective & Time-Saving: Building and maintaining CRA-compliant OS infrastructure in-house — hiring a DevSecOps engineer, maintaining SBOM tooling, managing CVE triage for 10+ years – costs far more than an InduTUX subscription. Our managed approach converts unpredictable engineering overhead into a fixed, predictable annual cost.
