HIGH RISK
The Verdict

Security updates are still active, which limits the most common attack surface. However, it has serious security gaps that put every device on your network at risk - every phone, laptop, camera, and smart device on this Wi-Fi shares that exposure.

The gaps are real enough to affect banking sessions, remote work, and anything sensitive passing through your home network. A D grade means the issues are documented and ongoing, not theoretical.

  • Your home network is more exposed than it should be

    Your home network is more exposed than it should be. Your work laptop, banking sessions, security cameras, and smart home devices all pass through this router - a flaw here gives an attacker leverage over all of them at once.

    Show technical detail

    Foreign manufacture - FCC ban applies: The Multy M1 is manufactured in China. The FCC foreign manufacture rule applies regardless of where Zyxel is headquartered.

  • 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.

    Show technical detail

    Zyxel critical CVE history: Zyxel products including mesh systems were affected by critical authentication and command injection vulnerabilities in 2022–2023. Ensure firmware is fully current.

  • A small gap that still touches every device on this network

    A small gap, not an urgent one - but it still touches everything on this network: your work laptop, your phone, your security cameras, and any guest device that joins the Wi-Fi.

    Show technical detail

    Limited security configuration in consumer mesh: The Multy M1 offers basic guest network isolation but lacks VLAN segmentation, VPN, or advanced firewall features available in prosumer alternatives.
