System Security Requirements
Implement system-level security requirements including access control, authentication, encryption, and audit logging for IACS.
Component Security
Ensure component-level security requirements for PLCs, HMIs, SCADA servers, and other industrial control components.
Patch Management
Establish OT-specific patch management processes that balance security updates with operational availability requirements.
Security Program
Develop and maintain a comprehensive industrial cybersecurity program with policies, procedures, and continuous improvement.
Implementation Methodology
A proven methodology refined across hundreds of compliance engagements.
Gap Assessment
Evaluate current state against framework requirements to identify gaps and priorities.

Frequently Asked Questions
What is IEC 62443?
IEC 62443 is a series of international standards for industrial automation and control systems (IACS) cybersecurity, covering organizational processes, system architecture, and component requirements.
Who needs IEC 62443?
Organizations operating industrial control systems, SCADA, DCS, or OT environments in manufacturing, energy, utilities, oil & gas, and critical infrastructure sectors.
How does IEC 62443 relate to NIST CSF?
IEC 62443 provides detailed OT-specific security requirements that can implement the broader NIST CSF functions in industrial environments. They are complementary frameworks.
Can you assess our existing OT security against IEC 62443?
Yes, we perform gap assessments against IEC 62443 standards, identify current security levels, and develop roadmaps to achieve target security levels.
