TuSimple and Yamaha Motor Group have joined the Automotive Information Sharing and Analysis Center along with two strategic partners, ArmorText and Celerium.

The inclusion of these four companies increases the strength of the Auto-ISAC’s position as the voice of the global auto cybersecurity information-sharing community as it works to prevent cyber threats to the connected vehicle, the organization reported.

The Auto-ISAC was formed by automakers in 2015 to promote collaboration between suppliers, commercial vehicle companies and automobile manufacturers around vehicle cybersecurity issues.

“Collectively, these companies will contribute valuable information to drive the industry’s proactive work to incorporate strong security measures into every phase of the vehicle lifecycle,” said Jeff Massimilla of General Motors, who serves as the group’s chairman.
