Moxa Europe: NPort 6000-G2 Series – Secure serial device server (GSA27-52)
The Moxa NPort 6000-G2 Series brings secure-by-design serial connectivity to machines and industrial plants where legacy serial devices remain business-critical. Many PLCs, meters, controllers, operator consoles, and service interfaces still rely on RS-232, RS-422, or RS-485 communication. These assets are proven and durable, but when connected to modern Ethernet-based OT networks, they can become a blind spot in the overall security architecture.
This is where the NPort 6000-G2 Series closes a critical gap. It acts as a secure gateway between legacy serial assets and today’s connected industrial environments, helping operators modernize securely without replacing installed equipment prematurely. In practice, this supports both plant availability and machine safety by reducing the risk of unauthorized access, insecure data exchange, and undetected incidents at the field level.
The NPort 6000-G2 Series is the world’s first serial device server certified to IEC 62443-4-2 Security Level 2 under the IECEE CB scheme. This is a relevant milestone for the industry because it applies recognized component-level cybersecurity requirements to a device class that has traditionally been overlooked, despite its importance in day-to-day operations.
Its value for machine and plant security lies in four areas:
Secure integration of legacy serial devices into modern OT security concepts
Support for corporate security policies through centralized authentication and remote syslog
Improved visibility and troubleshooting with built-in web-based serial traffic monitoring
Longer secure service life for installed assets, enabling retrofit instead of replacement
The NPort 6000-G2 Series helps manufacturers and operators strengthen defense in depth exactly where many attacks begin: close to the machine, close to the process, and close to critical operations.
