What is a VPN?
A VPN, or Virtual Private Network, is a technology that creates a secure, encrypted connection between your device and the internet. When you connect to a VPN, your internet traffic is routed through an encrypted tunnel to a server in a location of your choice, hiding your real IP address and protecting your data from anyone who might be watching.
Websites and online services see the VPN server’s IP address, not yours. This means advertisers, hackers, and even your internet service provider cannot track your online activity. Your data is encrypted end-to-end, making it unreadable even if intercepted.
Why do I need a VPN?
Every time you connect to the internet without a VPN, your activity is visible to your ISP, the networks you use, and potentially malicious actors. A VPN puts a secure layer between you and the internet, making your connection private and your data protected.
Whether you’re on your home network, a coffee shop’s Wi-Fi, or travelling abroad, a VPN keeps your browsing private, your identity hidden, and your data encrypted.
“A VPN is one of the simplest, most effective tools for protecting your privacy online.”

How does a VPN work?
When you activate TunnelBear, your device connects to one of our servers using strong AES-256 encryption. All traffic between your device and that server is encrypted — no one between you and the server can read it.
The VPN server then forwards your requests to websites on your behalf. Those websites see the server’s IP address, not yours. The response travels back through the encrypted tunnel to your device.
