The US has imposed a ban on all foreign-made consumer routers, citing significant supply chain vulnerabilities and severe cybersecurity risks that could disrupt critical infrastructure and harm national defense1. This prohibition applies to new routers, and existing ones are exempt from the ban. The Executive Branch has determined that foreign-produced routers pose a substantial threat to the US economy and national security. To mitigate this risk, any new router manufactured outside the US must now obtain approval from the Federal Communications Commission (FCC) before it can be imported. This move underscores the growing concern over the potential for foreign-made devices to be exploited by malicious actors, compromising the security of the US's critical infrastructure. The ban highlights the need for practitioners to carefully evaluate the security risks associated with foreign-made devices, particularly in sensitive environments, and to prioritize the use of trusted and approved devices to minimize potential vulnerabilities.
