What this means for you
The top 3 risks, most serious first.
-
Serious
It’s made abroad, so the FCC’s 2026 foreign-made router rule applies
The Multy M1 is manufactured in China. The FCC foreign manufacture rule applies regardless of where Zyxel is headquartered.
-
Moderate
Its software has a long record of security flaws
Zyxel products including mesh systems were affected by critical authentication and command injection vulnerabilities in 2022–2023. Ensure firmware is fully current.
-
