In today’s digital industrial era, connectivity and automation are transforming how manufacturing, energy, transportation, and industrial systems operate. But as operational technology (OT) becomes more networked and intelligent, cyber threats have also grown in scale and sophistication. Traditional IT cybersecurity frameworks aren’t enough to cover the unique risks inherent in industrial automation and control systems (IACS). This is where IEC 62443 enters the picture — a globally recognized cybersecurity standard designed specifically for industrial environments.

What is IEC 62443?

IEC 62443 is a series of international cybersecurity standards focused on securing industrial automation and control systems across their full lifecycle. Developed jointly under the International Society of Automation (ISA) and the International Electrotechnical Commission (IEC), these standards provide a comprehensive risk-based framework for identifying threats, defining controls, and verifying security measures for both products and systems in industrial settings.

Rather than being a single document, IEC 62443 is modular — addressing security needs at multiple levels:

  • Risk assessment and security program requirements
  • Secure development processes for products
  • Technical security requirements for products and systems
  • Guidelines for asset owners and service providers

This structure helps manufacturers, integrators, and end users establish processes that cover people, technology, and operational practices — not just device hardening.

Why ISO/IEC 62443 Is Important in Industrial Cybersecurity

1. Comprehensive Protection for OT and IACS

Industrial control environments have very different risk profiles from traditional IT systems — they run critical processes where a cyber incident can impact physical safety, production continuity, and regulatory compliance. ISO/IEC 62443 helps organizations systematically identify and mitigate these risks by embedding security practices into design, operations, and maintenance.

2. Recognized, Rigorous Framework for Security

Unlike proprietary or internal security approaches, ISO/IEC 62443 is internationally recognized and developed through consensus. It provides trusted benchmarks for how systems should be protected, helping engineers and architects make informed security decisions throughout the product lifecycle.

3. Enables Third-Party Validation and Trust

Achieving conformity or certification under the IEC 62443 framework involves independent testing and verification by accredited certification bodies. This third-party certification demonstrates that systems and products meet defined security criteria — an increasingly valuable signal of product trustworthiness to customers, partners, and regulators.

Lanner is strengthening industrial cybersecurity with IEC 62443.

As a leading provider of industrial cybersecurity platforms, Lanner is progressing toward IEC 62443 certification to further reinforce its commitment to security-by-design in industrial and mission-critical environments. By aligning product architecture, secure development processes, and system-level protections with internationally recognized IEC 62443 requirements, Lanner aims to deliver verifiable cybersecurity assurance for industrial automation and control systems. This initiative supports growing market and regulatory expectations across manufacturing, energy, transportation, and healthcare sectors, where compliance with global cybersecurity standards is increasingly essential.

IEC 62443 Certification also enables faster customer deployments, smoother system integration for partners, and broader acceptance in regulated global markets—demonstrating that Lanner’s industrial platforms are built not only for performance and reliability, but also for long-term cybersecurity resilience.
