Solution: IEC 62443-4-2 - Intrising Networks

IEC 62443-4-2 certified security for dependable industrial communications

802.1X Access Control

Enforces strict port-level access using 802.1X with RADIUS/TACACS+ to ensure only verified devices and users can join the network

Role-Based Access Control

Implements a Role-Based Access Control (RBAC) model to restrict administrative privileges, preventing unauthorized configuration changes

Secure Boot & Signed Firmware

Guarantees System Integrity by verifying the cryptographic signature of the firmware before boot-up, defending against malicious code injection

256b MACsec Support

Provides Data Confidentiality and authentication for traffic traveling between switches, securing communications at the Layer 2 level

Industrial networks face escalating cyber risks as operational technology (OT) environments become more interconnected and digitized. Industrial switches are central to real-time communication between controllers, sensors, and supervisory systems; that centrality also makes them attractive targets for attackers. Unauthorized access, malware, and network intrusions can disrupt processes, corrupt data, and endanger safety. Ensuring switches resist such threats requires rigorous cybersecurity measures aligned with IEC 62443-4-2 standards. Achieving certification is difficult because devices must combine robust protection with operational reliability.

Secure firmware update mechanisms and effective patch management are critical to address evolving threats, yet implementing these functions in rugged devices exposed to extreme temperatures, electromagnetic interference, and continuous vibration increases technical complexity. Interoperability and compliance create additional challenges. Switches must integrate smoothly into multivendor ecosystems while maintaining standardized security controls. IEC 62443-4-2 certification provides a structured framework to guide engineers and manufacturers in delivering resilient, secure industrial networking solutions and operational continuity assurance.

Our Solution

Managed switches with IEC 62443-4-2 certification address these challenges by incorporating security functions that strengthen network resilience without compromising industrial performance. They provide authenticated access, encrypted communication, and strict integrity validation to prevent unauthorized intrusion and ensure trustworthy data exchange. Built-in secure firmware updates, patch management, and cryptographic protections help safeguard devices against evolving cyber threats while maintaining operational stability in harsh industrial conditions.

Certified managed switches also enhance interoperability by adhering to standardized security requirements that support seamless integration with multivendor systems. Their advanced monitoring, logging, and anomaly-detection capabilities give operators continuous visibility into network behavior, enabling rapid identification of abnormal activities. By delivering consistent, verifiable security controls, IEC 62443-4-2 certified managed switches provide a reliable foundation for secure, compliant, and high-availability industrial networks.
