Operational Technology (OT) Compliance and Risk Management

While implementing technical controls and mitigations is essential, organizations operating Industrial Automation and Control Systems (IACS) must also consider broader Cybersecurity compliance and risk management responsibilities, for example, regulatory requirements and industry standards increasingly mandate demonstration actions by Industrial Automation system operators and end-users to mitigate cybersecurity risks to their systems.

Key Considerations:

• Cybersecurity Risk Assessments - Risk assessments help identify threat exposures to systems, prioritize risk mitigations and vulnerability handling. IEC 62443-3-2 and NIST SP 800-82 recommend regular assessments of IACS environments.

• Compliance Obligations - Depending on the region and sector, you may be subject to:

  • US Executive Order (EO) 14028

  • National Institute of Standards and Technology (NIST) Special Publication (SP) 800-218 and NIST SP 800-82

  • EU Directive 2022/2555, also known as NIS2 and the Cyber Resilience Act (CRA)

  • Industry-specific or customer-mandated requirements

  • IEC 62443 Security Requirements

We Can Support You

Watlow supports its customers by designing products with cybersecurity features that are aligned with international best practices, for example, IEC 62443 and National Institute of Standards and Technology (NIST). However, compliance and risk management responsibilities often require broader assessments across systems and networks.
