What Is a VPN?
A virtual private network 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, guaranteed to provide greater privacy than even a secured Wi-Fi hotspot.
Why You Need a VPN
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 required a password, any data transmitted during your online session was likely vulnerable to eavesdropping by strangers using the same network.
The encryption and anonymity that a VPN provides protects all of your online activities: sending emails, shopping online, or paying bills. VPNs also help keep your Web browsing anonymous.
