Well, considering Linksys is made by Cisco, it's not like they couldn't figure it out. I don't have one so I can't give you that side. I do know however that the Netgear router I have is just as secure(or insecure) as any other consumer router. There really won't be a difference beyond some weird proprietary feature or two. If you want good security, you shouldn't be looking at this kind of stuff, but they will all keep you safe from most things.
