F
HIGH RISK
The Verdict

This router has documented security problems. Every device on this network — your work laptop, banking app, Ring camera, smart lock — is running at higher risk than it should be.

An F is not a warning — it’s a finding that the router has been independently flagged for security or supply-chain concerns serious enough to warrant action.

  • Every device on your home network is exposed through a single point of failure

    Every device on your home network — phones, laptops, security cameras, smart speakers, baby monitors, smart locks — routes through this single point of failure. A flaw at this severity puts all of them in reach of one attacker.

    Show technical detail

    Long history of high-severity CVEs: Tenda routers have been the subject of dozens of disclosed CVEs including stack overflows and remote command execution. Many older models never received patches.

  • Tenda is legally required to share your network data with the Chinese government if asked

    The manufacturer is legally required to share your network data with the Chinese government if asked. This isn't theoretical — it's a legal obligation that can't be refused.

    Show technical detail

    The company behind this router is legally required to cooperate with Chinese intelligence: Shenzhen Tenda is subject to PRC intelligence law obligations.

  • A real gap that affects every device sharing this Wi-Fi

    It affects every device sharing this Wi-Fi — your work laptop, your phone, your kids' devices, your security cameras. Not the most urgent threat on the page, but a real edge an attacker can use to reach the rest.

    Foreign manufacture — FCC ban applies: Manufactured in mainland China.
