I'd start with a VPN. I'm personally a big fan of Tunnel Bear as it is incredibly easy to setup and has a good mobile app as well. TorrentFreak has some good VPN reviews. Lots more at https://www.reddit.com/r/vpnreviews/

Some posters in the original thread had reservations about VPNs https://news.ycombinator.com/item?id=12980878 .

For me the benefit of a VPN would be protection against my ISP being hacked rather than stopping someone with sufficient motivated from GCHQ accessing my data.
