Chinese Lidar Firm Hesai Faces U.S. Cyber Risk Accusations
Hesai Technology, linked to Nvidia, was designated a Chinese military entity by the Pentagon in 2024, raising national security alarms.
The U.S. Department of Defense blacklisted Chinese lidar manufacturer Hesai Technology in 2024, formally designating the company as a Chinese military entity and flagging it as a national security threat. The move placed Hesai among a growing list of Chinese technology firms that Washington has accused of maintaining ties to Beijing's defense apparatus.
Hesai's connections to Nvidia — one of the most prominent American semiconductor companies — have drawn additional scrutiny, raising questions about how deeply U.S. technology interests are entangled with firms the Pentagon considers security risks. The designation signals that American regulators are increasingly focused on the dual-use potential of advanced sensing and chip technologies.

Lidar technology, which uses laser pulses to create precise three-dimensional maps of environments, sits at the heart of autonomous vehicles, robotics, and military surveillance systems. That breadth of application makes companies like Hesai strategically significant — and, in Washington's view, potentially dangerous if their data collection or hardware could be leveraged by the Chinese government.
The Pentagon's designation does not automatically trigger a full trade ban, but it subjects Hesai to heightened restrictions and reputational pressure that can deter American partners and investors. As the U.S.-China technology rivalry intensifies, cases like Hesai's illustrate the difficult position faced by multinational firms caught between two competing tech ecosystems.
