Level 3
I have a spare PC right now with two network cards. Currently I am running Sophos UTM HOME 9.3. Is that decent enough? I want to provide a whole house security even for the guests who are visiting and want to use my network. I don't want their infected PC's/devices to infect mine.
I also, would want to block any ads and tracking thingies in my mobile devices and PC's without the need to install anything on the mobile device. Yes, I know that once I leave the house I am at the mercy of the ads due to my cell network.

Basically I am looking at the ring 0 defense layer...I will still run Antimalware at the home PC's but I want something to act as the initital gate keeper.

So far Sophos UTM home is good but I was wondering if there is something better out there.
