The risks using open public WiFi networks has been done to death.
What I've been wondering is whether an open WiFi network (typically public) is safe against packet-sniffing if that network is using client isolation?
(Putting aside the still-important risk of an evil twin which the above does not mitigate against)
As I understand it, using client isolation means just that. If a bad actor connects to the same open network, they, and myself for that matter, are limited to our own broadcast domain. Which effectively means, they can't see my traffic. Period.
Assuming the answer is yes (client isolation prevents packet-sniffing), to what degree does client isolation make using an open network safer to use?
Follow-up to above, is there a good tool to test if this has been implemented on a said open network? My idea would be to connect another device to that same network and unleash some nmap goodness to validate.
