U.S. federal authorities are investigating TP-Link, a Chinese router manufacturer that holds approximately 65% of the U.S. home router market, over potential national security risks. The investigations by the Departments of Commerce, Defense, and Justice focus on security vulnerabilities linked to cyberattacks associated with TP-Link's internet routers, which are widely used in American households. This scrutiny could lead to a ban on the sale of TP-Link routers in the United States as early as 2025. The probes come amid growing concerns about the security implications of using Chinese-made technology in critical infrastructure and consumer devices.
