What is a VPN?
A VPN (Virtual Private Network) is a service that encrypts your internet connection and hides your online identity, allowing you to browse the web privately and securely.
Why Do You Need a VPN?
- Protects your data on public Wi-Fi networks
- Hides your browsing activity from your ISP (Internet Service Provider)
- Masks your IP address and location
- Bypasses geographical restrictions on content
- Helps prevent tracking and targeted advertising
How Does a VPN Work?
A VPN creates an encrypted tunnel between your device and a VPN server. All your internet traffic passes through this tunnel, making it unreadable to anyone who might try to intercept it. When you access websites through a VPN:
- Your data is encrypted before leaving your device
- The encrypted data travels to the VPN server
- The VPN server decrypts your data and sends it to the destination website
- The website sees the VPN server's IP address, not yours
- Responses follow the same encrypted path back to your device
Choosing the Right VPN
Look for these important features when selecting a VPN service:
- Strong encryption: AES-256 is the industry standard
- No-logs policy: The provider doesn't store records of your online activities
- Kill switch: Automatically disconnects your internet if the VPN connection drops
- Server locations: Multiple servers in various countries for better access options
- Speed and reliability: Minimal impact on your internet connection speed
- Compatible apps: Available for all your devices (computer, phone, tablet)
