If you regularly use public WiFi, travel for work, worry about Internet security, or simply value you privacy, you’re probably considering getting a VPN (Virtual Private Network).

A VPN is essentially a protective “tunnel” that secures the connection between your laptop, smartphone or tablet and the Internet. This ensures that all your online activity is protected from hackers, peeping toms, or others with malicious intent who are using the same network.

But, before you got out and buy one, it’s important to consider your needs and usage habits so that you choose the best possible VPN for you!

Here are 4 questions to consider before you buy a VPN:

1. Do you regularly travel out of the country? Many of your favorite services, like Netflix, Hulu, or Amazon on Demand, are blocked once you travel outside of the USA, and many decide to get a VPN to bypass these limitations. To ensure you get the right one for you, ask your VPN service provider if they have exit servers in the U.S. meaning that you can “appear” to be in the United States when you’re actually enjoying a cappuccino in Rome. (GhostPath VPN is totally equipped to help you bypass any foreign country limitation, so you can catch up on House of Cards even while you’re abroad.)
2. Can it be used across all your devices? You may think you only need a VPN for your computer, but the truth is more and more Internet security breaches are occurring on our smartphones and tablets because they’re portable and we can easily use them in public (often on unsecured WiFi networks). (Our GhostPath VPN works seamlessly with laptops, computers, smartphones and tablets, so no matter what device you’re using, you’re covered!)
3. Can I use it on my router? Using a VPN in conjunction with your wireless router is a great way to protect all of your internet connected devices in one fell swoop. (GhostPath supports using DD-WRT to connect to the VPN at the router level, meaning all your internet connected devices are protected. Keep in mind DD-WRT will only work if it’s supported by your router.)
4. Are there any limitations? Make sure to ask about bandwidth limitations, as that can greatly impact your user experience. Also, ask if the VPN you’re considering works with all service providers. (GhostPath syncs with all major operating systems including Windows, Mac OS X, Ubuntu, Android, and iOS. And, there are no download limits, no throttling, and no maximum number of server changes! You are free to use our service however you see fit.)
