Hotspot Shield is the go to product for free wireless hotspot security. Yes, it has ads, that is how it can be free. Yes, it has a limit on how much traffic you can use, that is how it can be free. Yes, you have to download software to your computer to run it. Yes, it sets up a VPN between your computer and AnchorFree servers and encrypts the data in between so that balding bloated leather jacket in the summer wearing guy with the laptop can't grab your passwords out of the air without some serious work. Yes it takes over your whole network connection, no proxies, no worries about using your FTP client.
Pros:
- FREE!
- Encrypts all network traffic, not just the web browser.
Cons:
- 3 GB Per 30 day limit
- ADs. Big ad banner on the top of every page. You can close it, but it will be back with the next click.
