Functional Testing for IEC 62443 Compliance
What Is Functional Testing for IEC 62443?
Functional testing ensures that Industrial Control Systems (ICS) and Operational Technology (OT) meet the highest cybersecurity standards. This process validates that security controls operate as expected, protecting industrial environments from cyber threats, unauthorized access, and operational disruptions.
As part of IEC 62443 compliance, functional testing helps manufacturers, system integrators, and asset owners confirm that their systems are cybersecure, resilient, and aligned with regulatory requirements before deployment.
What We Test
Our comprehensive cybersecurity assessment covers all critical security controls required by IEC 62443, ensuring that your industrial systems are built to withstand cyber threats.
Threat Simulation & Risk Analysis for Industrial Cybersecurity
We simulate real-world attacks (privilege escalation, lateral movement, denial-of-service) to identify vulnerabilities in industrial systems. Assess risks to operations, safety, and compliance (IEC 62443, NIST), protecting against ransomware and advanced cyber threats.
We verify that only authorized personnel can access critical systems, ensuring role-based permissions and preventing unauthorized entry.
Testing authentication mechanisms like multi-factor authentication (MFA), certificates, and passwords to confirm that only approved users gain access.
We assess encryption protocols to ensure confidentiality and integrity of sensitive data, preventing interception and unauthorized access.
Testing of intrusion detection and prevention systems (IDS/IPS) to ensure early detection of cyber threats and anomalies in network traffic.
Validation of hashing, digital signatures, and logging mechanisms to protect data from corruption or unauthorized modification.
The Outcome:
A Cyber-Resilient Industrial System
With functional testing, your industrial control systems are ready to face real-world cyber threats, ensuring a secure, standards-compliant infrastructure that meets IEC 62443 requirements.
