IEC 62443 is a comprehensive cybersecurity framework for industrial automation and control systems (IACS). XQ Zero Trust Data Security aligns with key IEC 62443 standards by ensuring data protection, secure access, and compliance with industrial cybersecurity requirements. Below is a breakdown of how XQ meets specific IEC 62443 requirements:

📌 IEC 62443-3-3: System Security Requirements and Security Levels

SR 1.1 - Human User Identification and Authentication

XQ enforces strong identity verification before granting access to encrypted data, reducing unauthorized access risks.

SR 3.1 - Communication Integrity

XQ encrypts data end-to-end to prevent unauthorized tampering or interception during transmission.

SR 3.3 - Security Event Logging

XQ provides audit-ready logs and real-time reporting, ensuring forensic traceability for compliance audits.

📌 IEC 62443-4-2: Technical Security Requirements for IACS Components

CR 1.4 - Strength of Encryption

XQ ensures post-quantum-ready encryption and supports external key management to strengthen cryptographic security.

CR 2.1 - Asset Inventory for Cybersecurity

XQ enables visibility into data flows, ensuring that organizations can track and control data access across the supply chain.

CR 3.4 - Application Hardening

XQ implements geofencing and granular access controls, restricting data to authorized locations and personnel.

📌 IEC 62443-2-4: Security Program Requirements for Service Providers

Security Policy Enforcement

XQ enables automated policy enforcement for secure file and database access, helping organizations adhere to industrial security mandates.

Supply Chain Security (Third-Party Risk Management)

XQ mitigates third-party risks by allowing organizations to retain control over encryption keys, even when data is shared externally.

By aligning with IEC 62443 standards, XQ simplifies cybersecurity compliance while reducing operational complexity, labor costs, and data breach risks in industrial environments.

How XQ Meets IEC 62443 Compliance

Zero Trust Architecture: Ensures secure communication across industrial control systems (ICS) by enforcing least-privilege access.
End-to-End Encryption: Protects sensitive data in transit and at rest, preventing unauthorized access or tampering.
Granular Access Controls: Enables role-based encryption and real-time access revocation to limit data exposure.
Secure Key Management: Uses external, independently managed encryption keys to prevent key compromise risks.
Geofencing & Data Sovereignty: Restricts data access based on geographic policies, ensuring compliance with location-based regulations.
Audit-Ready Reporting: Automates logging and compliance reporting for easier IEC 62443 validation and cybersecurity audits.
Seamless Integration: Works with existing ICS environments and cloud infrastructure without disrupting operations.
Resilience Against Cyber Threats: Mitigates ransomware, insider threats, and data exfiltration risks through advanced data security controls.
