Hotspot Shield

When you connect to the Internet via a public hot spot, you put yourself at risk because someone might try to sniff your packets or otherwise snoop on what you're doing online. Hotspot Shield, a free, lightweight piece of software from AnchorFree, promises to keep you safe by creating a secure VPN connection and encrypting all of your communications.

Hotspot Shield
Hotspot Shield lets you use a VPN to protect yourself while using a public hot spot.

As you connect to a hot spot, simply run Hotspot Shield, and it will begin protecting you using the HTTP Secure (HTTPS) protocol. It launches a tab to show you that you're connected; to disconnect, click the Disconnect button on the tab. To connect again, click the Connect button. You can also connect and disconnect by right-clicking the program's icon in the System Tray.

You'll need to take some care when you first install Hotspot Shield. If you don't want its toolbar installed in your browser, uncheck the box next to "Include the Hotspot Shield Community Toolbar." Also, make sure to uncheck the boxes for setting Hotspot Shield Private Search as your default search, setting your home page to the Hotspot Shield Private Search page, fixing "Page Not Found" errors, and enabling you to get instant alerts from the software -- those options won't do you much good and will likely annoy you.

A few caveats: When you run the software, it will open a browser tab to the product's home page, which has ads on it. You can close that tab if you want; the program works fine without it open. Also, according to a page on the Hotspot Shield Web site, you might see targeted ads appear above Web pages you visit. That hasn't happened to me, although I've seen complaints elsewhere around the Web about intrusive ads. Finally, some people who have downloaded the program have complained that it is unstable, or they were unable to uninstall it. In my tests I didn't run across those problems, but be forewarned that others have reported them.

While AnchorFree offers Hotspot Shield for free, other companies sell similar VPN software products to protect you at public hot spots. ConnectInPrivate, for example, offers software and a service that costs $14.99 per month.
