Cybersecurity is no longer confined to the IT department. As today’s Class 8 trucks become increasingly connected, technicians, maintenance professionals, and fleet operators need practical ways to understand what’s happening on a vehicle’s network and identify potential security concerns before they become operational problems.
That’s exactly why the National Motor Freight Traffic Association, Inc.® (NMFTA)® developed the Trucking Cybersecurity Assessment Tool (TCAT).
TCAT is designed to help transportation professionals more easily interact with vehicle bus and electronic control units, capture and analyze network traffic, and better understand the cybersecurity posture of heavy-duty vehicles. Whether you’re supporting a fleet, conducting research, or maintaining vehicles in the shop, TCAT provides valuable insight into how modern truck systems communicate and operate. If you know what you have, and how it’s configured, it’s easier to secure. In turn, fleets will be able to make better, more informed, purchasing decisions, especially when it comes to potentially less secure aftermarket devices.
At the 2026 NMFTA Cybersecurity Conference, attendees will have the opportunity to go beyond a demonstration and gain hands-on experience using the tool. Participants will learn the tool’s core capabilities, including capturing and analyzing vehicle network data and interacting with vehicle diagnostic systems.
This training will contain hands-on elements to enable deeper understanding of the TCAT and its capabilities and, ultimately, be integrated into shop and lab cybersecurity workflows.
By the end of the training, participants will leave with a stronger understanding of both the technology behind modern commercial vehicles and the processes that can help protect them.
As cybersecurity continues to become an essential part of fleet operations, having the right tools—and knowing how to use them—will be just as important as understanding traditional vehicle maintenance.
I look forward to seeing you in Long Beach!
