Industrial Cybersecurity
With the growing convergence of IT and OT, industrial systems are becoming more connected—and more vulnerable. They face risks like unauthorized access, ransomware, and supply chain attacks. To address these threats, the IEC 62443 standard series provides a comprehensive framework for securing Industrial Automation and Control Systems (IACS) including PLCs, SCADA systems, and industrial IoT devices.
IEC 62443, the global standard for industrial cybersecurity, offers a structured framework to secure Industrial Automation and Control Systems (IACS) across their lifecycle. It promotes risk-based security levels, defense-in depth strategies, and clear role definitions for stakeholders.
At eInfochips, we offer comprehensive industrial cybersecurity services aligned with IEC 62443-4-1, IEC 62443-4-2, and IEC 62443-3-3 standards. Our offerings include system-level risk assessments and security capability mapping (IEC 62443-3-3), secure product development lifecycle support (IEC 62443-4-1), and embedded system and component-level security hardening (IEC 62443-4-2). Whether you’re upgrading legacy systems or developing secure-by-design industrial solutions, we help ensure your products are secure, compliant, and resilient.
