I understand and know what you are talking about. However my opinion is I don't trust this security system. Can this system protect our devices as much as dedicated network security devices such as enterprise firewalls and small office firewall? I don't think so. I don't trust consumer grade router security. That is what I wanted to say.
'zero logical sense'? What if the door locks have been compromised? I saw some hacked Asus routers including some other routers. Those routers were turned on firewall and AiProtection. Chinese attackers were using them as VPN servers. I think Asus Aiprotection and Netgear Amor are just marketing tactics until now.
I just don't trust them at all. That's it.
That's not the same thing as claiming that it's stupid. Yes, business-class services will provide better protection, however It's still better security than not having these at all.
I've seen AiProtection actually do something useful personally (I had a RDesktop forwarded for a while on my router for a particular project). AiProtection blocked and reported a number of brute-force attempts targeting the RDesktop protocol specifically.
