I see you mention that brand a lot but I dont see very many (to none) offerings for the home. I certainly am not interested in enterprise equipment. I would expect with a limited line of consumer products that you will only see a fraction of the security issues vs companies with lines many times greater. Yet I am not doubting your knowledge at all.
I take reasonable (more than most the population) precautions with everyday name brand equipment, there are much, much better fish to go after

than me. I always tend to buy a router after its been out 2ish years and price reductions due to the newest Wifi standard coming out when I am happy with ac, sure next one will be an AX, its unavoidable. Anyway, range is most important to me and why I hesitate to get rid of the MR2600, it's flawless in that regard. Enthusiasts would cringe at the limited UI of the router, heck it even upset me at first *LOL* but it does what it does very well.
My MR2600 is now out of production and for fun Im tempted to get a new router after having this one for three going on 4 years will be Nov 2024. This would be a preemptive move, I mean the thing has to fail sooner or later. Though I still have an older TPlink that I replaced as an emergency back up should it fail I could use it until buying a new one. (wife works from home so back up important)
I actually hesitate, its been so dead on reliable with incredible range and the price always boggled my mind, just always works, never needs reset, get within a few percent of the 300/300speed we pay for over WiFi throughout the house on so many devices I get tired of counting them. Therein I think is more concerning than the router. The devices themselves I see as a security risk. However I am not nor is it my field like yours so have no idea what I am talking about, expect Im more aware and informed then the Joe next door.
Anyway, not jumping into anything, might wait until Nov or whenever but I typically look to buy one standard+ older routers meaning $200 to $250 routers for around $130 to $160. when the "new" line up comes out. I find the Archer AX55 interesting which is stupid cheap right now at $94. The other extreme is the bargain priced Archer AX6000 but in reading it says it runs hot I think and not power efficient ... anyway, just a small sample of what I am looking at. I am not going to be roped into a subscription service by any router company. I read, I think NETGEAR it terrible about this, along with privacy concerns.
It's amazing how Antennas can make a router look beefy. *LOL*

Just to be clear, I like shopping the internet on days I am bored. I might not do anything at anytime and other times I do, like, back in 2022 when we had a new house built *LOL* and moved in 2023. (my wife jokes about it)
