A virtual private network (VPN) creates a secure, encrypted tunnel between your device and the Internet. It masks your real IP address with the IP of the VPN server, keeping your location and online activity hidden from ISPs, websites, advertisers, and potential hackers.
How does VPN work?
Your device encrypts the data before sending it to the remote VPN server. The server decrypts it and sends it to the destination site, which is visible only to the server’s IP address. Responses return through an encrypted tunnel. It protects data on public Wi-Fi and prevents interception.
advantages
– Better privacy — reduces tracking and targeted ads.
– Enhanced security — Keeps sensitive information like logins and payments secure.
– Access geo-restricted content — bypasses regional blocks on streaming/services.
– Avoid ISP throttling — Hides activity to maintain speeds.
Loss
– Speed loss — Encryption/rerouting can slow down connections, especially on remote/overloaded servers.
– Price — premium services require a subscription; Free ones often log data, show ads, or are not reliable.
– Detection/Blocking — Some sites (like Netflix) block VPN IPs.
– Battery/data consumption – Continuous use affects the mobile.
– Legal restrictions — Banned/restricted in some countries.
