Re: Zyxel?
We use their basic model gigabit switches and have been happy enough considering the low cost and not being on Uncle Sam's naughty list of Chinese OEMs (we used GS1900 series). Obviously keeping the management addresses off the Internet! The fancier switches have a cloud management feature which is just a hard NO! for me.
They do a small PoE model with 8 copper ports and two SFP so you can make a very cheap and effective network extender with fibre between buildings, etc, with that for PoE web cameras, WiFi access points, or similar. But Zyxel, like most other big names (Cisco, Sonicwall, Fortinet, Juniper, etc), seem unable to do a secure security appliance. Almost that name along hexes a product...
