A virtual private network (VPN) gives you online privacy and anonymity by creating a private network from a public internet connection. VPNs mask your internet protocol (IP) address so your online actions are virtually untraceable. Most important, VPN services establish secure and encrypted connections to provide greater privacy than even a secured Wi-Fi hotspot.
Why do you need a VPN service?
Surfing the web or transacting on an unsecured Wi-Fi network means you could be exposing your private information and browsing habits. That’s why a virtual private network, better known as a VPN, should be a must for anyone concerned about their online security and privacy.
Think about all the times you’ve been on the go, reading emails while in line at the coffee shop, or checking your bank account while waiting at the doctor’s office. Unless you were logged into a private Wi-Fi network that requires a password, any data transmitted during your online session could be vulnerable to eavesdropping by strangers using the same network.
The encryption and anonymity that a VPN provides helps protect your online activities: sending emails, shopping online, or paying bills. VPNs also help keep your web browsing anonymous.
How a VPN protects your IP address and privacy
VPNs essentially create a data tunnel between your local network and an exit node in another location, which could be thousands of miles away, making it seem as if you’re in another place. This benefit allows online freedom, or the ability to access your favorite apps and websites while on the go.
Here’s a closer look at how a virtual private network works. VPNs use encryption to scramble data when it’s sent over a Wi-Fi network. Encryption makes the data unreadable. Data security is especially important when using a public Wi-Fi network, because it prevents anyone else on the network from eavesdropping on your internet activity.
There’s another side to privacy. Without a VPN, your internet service provider can know your entire browsing history. With a VPN, your search history is hidden. That’s because your web activity will be associated with the VPN server’s IP address, not yours. A VPN service provider may have servers all over the world. That means your search activity could appear to originate at any one of them. Keep in mind, search engines also track your search history, but they’ll associate that information with an IP address that’s not yours. Again, your VPN will keep your online activity private.
