What Is a VPN?
Put simply, a Virtual Private Network, or VPN, is a group of computers (or discrete networks) networked together over a public network—namely, the internet.
Businesses use VPNs to connect remote datacenters, and individuals can use VPNs to get access to network resources when they’re not physically on the same LAN (local area network), or as a method for securing and encrypting their communications when they’re using an untrusted public network.
When you connect to a VPN, you usually launch a VPN client on your computer (or click a link on a special website), log in with your credentials, and your computer exchanges trusted keys with a far away server.
Once both computers have verified each other as authentic, all of your internet communication is encrypted and secured from eavesdropping.
The most important thing you need to know about a VPN:
A VPN secures your computer’s internet connection to guarantee that all of the data you’re sending and receiving is encrypted and secured from prying eyes.
Whether the VPNs you’re familiar with are the ones offered by your school or business to help you work or stay connected when you’re traveling or the ones you pay to get you watch your favorite shows in another country as they air, they’re all doing the same thing. For much more detail on what VPNs are, how they work, and how they’re used, check out this How Stuff Works article.
Why You Need a VPN, or How You Can Benefit from Using One
A VPN alone is just a way to bolster your security and access resources on a network you’re not physically connected to. What you choose to do with a VPN is a different story. Usually, VPN users fall into a few separate categories:
- The student/worker
- This person has responsibilities to attend to, and uses a VPN provided by their school or company to access resources on their network when they’re at home or traveling.
- In most cases, this person already has a free VPN service provided to them, so they’re not exactly shopping around.
- Also, if they’re worried about security, they can always fire up their VPN when using airport or cafe WI-Fi to ensure no one’s snooping on their connection.
- The downloader
- Whether they’re downloading legally or illegally, this person doesn’t want on some company’s witch-hunt list just because they have a torrenting app installed on their computer.
- VPNs are the only way to stay safe when using something like BitTorrent—everything else is just a false sense of security.
- Better safe than trying to defend yourself in court or paying a massive fine for something you may or may not have even done, right?
- The privacy minded and security advocate
- Whether they’re a in a strictly monitored environment or a completely free and open one, this person uses VPN services to keep their communications secure and encrypted and away from prying eyes whether they’re at home or abroad.
- To them, unsecured connections mean someone’s reading what you say.
- The globetrotter.
- This person wants to watch a major sports event live, without dealing with their crummy local networks.
- They want to check out their favorite TV shows as they air instead of waiting for translations or re-broadcasts (or watch the versions aired in other countries,) listen to location-restricted streaming internet radio, or want to use a new web service or application that looks great but for some reason is limited to a specific country or region.
- Some combination of the above
- Odds are, even if you’re not one of these people more often than not, you’re some mix of them depending on what you’re doing.
- In all of these cases, a VPN service can be helpful, whether it’s just a matter of protecting yourself when you’re out and about, whether you handle sensitive data for your job and don’t want to get fired, or you’re just covering your own ass from the MPAA.
Even if none of the above really sound right to you, you can still benefit from using a VPN.
