When it comes to browsing the web, your personal information is a lot less protected than you may think. When you access the internet via standard networks, much of your activity is visible to your internet service provider (ISP) and the companies that own the websites you visit.
A VPN, or virtual private network, helps you protect your personal information and gain privacy online. Essentially, a VPN funnels your activity through a remote server so no one can trace where you are or what you access on the web.
But what is a VPN, how does it work, and what are the full benefits? Read on to learn more.
A VPN encrypts your data by running it through a remote server, which could be anywhere in the world. Instead of a direct transmission between you and your ISP, your data first passes through a sort of “tunnel” or “encoder” (the VPN), and the same thing happens when websites transmit data back to you.
This encryption hides your identity, location, and activity from your ISP, third-party websites, or hackers who may be trying to steal your data. Instead of seeing your internet protocol (IP) address, which uniquely identifies your device and location, they only see a jumble of indecipherable data and the IP address of your VPN.
You can’t simply jump on a VPN, however. These services require a subscription, and though some are free, you’ll typically pay anywhere from $2 to $15 a month for access. That may be worth it, though, depending on what you need from a VPN.
VPNs have many benefits, but they primarily come down to privacy and security. Here’s a look at four common uses of VPNs.
Privacy is the most common use for VPNs, and it reflects a concern many people have about using the internet.
Consider what usually happens when you visit websites or search for products online. Before long, you’re seeing ads for similar products in your email, on social media, or along website banners. That’s because your IP address and activity told those companies everything they needed to know to find you and send advertising your way.
With a VPN, companies can’t target you in this way. If you want to keep brands out of your business, this is the easiest way to do it.
Accessing the internet without a VPN leaves not only your browsing activity but also your location exposed. Companies can see where you are (generally, not your specific home address) as you search for information or products and target advertising or marketing efforts based on your location.
Note that if you log in to an account with any third-party website or provider, your activity will be logged through your account. However, your IP address is still encrypted, so the provider can’t tie any of that activity to your location.
When you access the internet from a public Wi-Fi connection, your activity and personal information are exposed to any hackers on the network who want to seek it out. If you log in to a website, for instance, you risk having your password stolen by cyber-criminals.
A VPN provides an additional layer of security. By connecting to the VPN before you pass any sensitive data over public Wi-Fi, you can ensure your activity is fully encrypted. This can also protect you from some malware and other types of cyber-attacks.
Blocking your location isn’t only advantageous for hiding from companies and their advertising schemes. It can also prove helpful for online shopping, searches, and other activities. For instance, you may find pricing on online retail or travel sites when browsing from a VPN based outside the U.S.
A VPN may also unlock access to content that’s not available in your area, such as movies or TV shows that aren’t available to stream in the U.S. Some people even use VPNs to access blacked-out content on streaming services. Before you follow suit, however, keep in mind that this may violate the terms of service for your streaming provider.
VPN providers vary widely in terms of their features and functionality. Businesses and individuals value different features, but in general, you’ll want to consider things like cost, speed, and device/operating system compatibility when comparing VPNs. Make sure the provider uses industry-standard security like 256-bit AES encryption, too. Although there are free VPNs, it’s usually worth paying even a small amount to avoid advertising or having your information sold.
Some of the best available VPNs include:
Ultimately, your VPN choice comes down to your individual, household, or business needs. If you regularly transmit highly sensitive data for work, higher levels of security should be your top priority. On the other hand, if you simply want to keep your internet activity and location private at home, one of the more budget-friendly options may suit you just fine.
If you are connected to a VPN, you should be able to find it in your Wi-Fi settings or computer control panel, though it varies by operating system. You can also visit whatismyproxy.com to see if it shows you are connected to a VPN or proxy server.
Yes, VPN services offer mobile apps that allow you to connect to the server directly, regardless of how you are connected to the internet.
A VPN provides an extra layer of protection against hackers by encrypting your IP address and any information you transmit over the internet. Keep in mind, however, that VPNs won’t protect against all cyber-attacks, such as some malware and phishing attacks.
