Digital Yacht N2K Protect NMEA 2000 Network Guard – Maritime Cyber Security Device

N2K Protect NMEA 2000 Network Guard

With more technically advanced, integrated, and connected boats, security becomes a major concern. Recent high-profile automotive hacks have highlighted security weaknesses in some CAN-based systems.

The NMEA Organisation has responded to this threat by establishing a Cyber Security Working Group to identify and mitigate the risks of maritime attacks

N2K Protect is the Worlds first cyber security product, focused on NMEA 2000, to be developed as part of this NMEA initiative

N2K Protect is a self-contained, bus-powered, unobtrusive black box that receives and analyses all NMEA 2000 network data.

Key Functions:

• Test and validate the NMEA 2000 network during installation


• Tools for NMEA 2000 configuration and network monitoring/analysis


• Ongoing 24/7 monitoring and protection for the life of the vessel

Features:

• Worlds first NMEA 2000 Cyber Security Device


• Tests validates the NMEA 2000 network during installation


• Allows configuration of other NMEA 2000 devices


• View and analyze the NMEA 2000 network with device and PGN displays plus raw data logging


• 24/7 monitoring of the NMEA 2000 network


• An integrated WiFi antenna can create its own WiFi network or join the vessels wireless network


• Configuration and monitoring via built-in web interface


• 92dB internal buzzer for alerts


• Ability to generate SMS alert messages when used with a Digital Yacht 4GX or 5GX product for remote alerts


• Self-contained, bus-powered, unobtrusive IP54-rated black box


• Future-proof design, with easy-to-update firmware via web interface to keep unit aligned with current threats

User Installation Interface:

• N2K Protect has a built-in wireless interface so any browser-enabled device can access its functionality phone, iPad, tablet, or PC


• Simply search for its secure wireless network and log


• Capability to join another network on larger systems


• No complicated or proprietary apps

As modern vessels become increasingly connected and technologically advanced, the importance of cybersecurity in marine networks continues to grow. The Digital Yacht N2K Protect NMEA 2000 Network Guard is the world's first dedicated cyber security device designed specifically for NMEA 2000 networks, addressing the rising concern of maritime cyber threats. This self-contained, bus-powered black box seamlessly integrates into your vessel's existing network, providing continuous protection and monitoring without disrupting system operation.
Designed for ease of installation, N2K Protect connects directly into the NMEA 2000 backbone, requiring no complicated setup or proprietary software. Its built-in wireless interface allows users to access network data and configuration through any device with a web browser—such as a smartphone, tablet, or PC—by joining its secure WiFi network. The device also supports connection to the vessel's existing wireless network, enabling remote monitoring and alerts. The integrated web interface offers comprehensive tools for network testing, device configuration, and real-time analysis, making installation and ongoing management straightforward.
Key security features include 24/7 network monitoring, PGN and raw data logging, and an internal 92dB buzzer for immediate alerts. When paired with compatible Digital Yacht products like 4GX or 5GX, the N2K Protect can send SMS alerts for rapid response to potential threats. Its future-proof design allows firmware updates via the web interface, ensuring the device remains aligned with evolving cybersecurity threats and standards. The N2K Protect is rated IP54, making it suitable for marine environments with protection against dust and water ingress, and its unobtrusive form factor minimizes its impact on vessel aesthetics and space.
Ideal for both new installations and retrofits, the Digital Yacht N2K Protect NMEA 2000 Network Guard offers a vital layer of security for modern boat systems, safeguarding critical data and ensuring operational integrity in an increasingly connected maritime environment.
