Why Device Hardening Matters

Secure network architecture helps contain cyber threats across OT environments. However, vulnerabilities within network devices can still create entry points for attackers if not properly secured.

Device hardening reduces this risk by embedding security into device design and functionality, helping prevent the exploitation of vulnerabilities. Moxa addresses this challenge through a Secure-by-Design development approach, embedding security into products from the earliest design stages and supporting them with built-in protection mechanisms and lifecycle vulnerability management.

Vulnerability Management

Secure-by-Design Development

  • Security begins at the earliest stages of product development. Moxa follows a Secure-by-Design approach that integrates cybersecurity practices throughout the product lifecycle to reduce vulnerabilities before products are deployed.

    Key practices include:

    • Threat modeling during system architecture design
    • Secure coding standards and development guidelines
    • Security requirements integrated into product validation
    • Security testing and vulnerability scanning
  • This development approach enables Moxa devices to incorporate embedded security functions such as:

    • Device integrity and authenticity verification (Secure Boot)
    • Least-functionality design to disable unnecessary services
    • User authentication and role-based authorization
    • Network access authentication to control device connectivity
    • Encrypted communication for device configuration and management

Industrial Cybersecurity Standards Alignment

Moxa aligns its products with internationally recognized industrial cybersecurity standards to ensure devices meet trusted security requirements.


These include:

  • IEC 62443-4-1 Secure development lifecycle certification
  • IEC 62443-4-2 Security capabilities for industrial automation devices
  • EU Cyber Resilience Act (CRA) and RED-DA cybersecurity requirements (Learn more: Moxa’s Commitment to CRA)

  • JC-STAR certification for cybersecurity compliance in Japan

Moxa is among the first companies globally to achieve IEC 62443-4-1 certification for its secure development lifecycle, and several product lines have also been certified to these standards. This demonstrates Moxa’s commitment to delivering secure and trustworthy networking and connectivity devices for global industrial deployments.

Cybersecurity Vulnerability Management

Cyber threats evolve continuously, making ongoing vulnerability management essential for maintaining device security over time.


Moxa operates a dedicated Product Security Incident Response Team (PSIRT) that manages vulnerabilities through a structured process:

  • Monitoring security alerts and vulnerability reports
  • Investigating potential impacts on affected products
  • Developing mitigation guidance and firmware updates when available
  • Publishing security advisories and remediation recommendations

This structured approach helps organizations respond to emerging threats and maintain secure industrial networks. Visit here to learn more about Moxa PSIRT and vulnerability management policy.
