So I am new to using VPNs. I don't torrent, or need to hide internet use from the wife, and I know a VPN service doesn't actually offer as much privacy as they want you to think. What I do want to use it for is traveling. Specifically my wife and I want to stream stuff and generally browse when we are staying at a house we're staying at with some friends this summer. I'm pretty sure they'll offer free public wifi...which make me uneasy. I basically just want to know if IKEv2 apps for iOS are secure enough to ward off anybody using wireshark to try to sniff out passwords and that sort of thing. All the privacy advocate cry foul about IKEv2 and the NSA, which I honestly am not worried about. I don't use the internet for much more than light browsing, and obviously we won't be using any sensitive data. I just want to practice general caution.
