A VPN (Virtual Private Network) creates an encrypted tunnel between your device and a remote server operated by the VPN provider. All your internet traffic is routed through this tunnel, masking your real IP address and encrypting your data from anyone monitoring the connection.
What a VPN Does
- Encrypts your traffic — Prevents ISPs, governments and hackers on public Wi-Fi from reading your data.
- Masks your IP address — Websites see the VPN server's IP, not your real IP.
- Bypasses geo-restrictions — Access content available in other countries by connecting to a server there.
- Hides your location — Useful for privacy-conscious users.
What a VPN Does NOT Do
- Does not make you anonymous online — the VPN provider can see your traffic.
- Does not protect against malware, phishing or browser cookies.
- Does not hide your activity from the VPN provider itself — trust is essential.
When to Use a VPN
- Using public Wi-Fi at airports, hotels or cafés.
- Accessing sensitive work data remotely.
- Protecting your privacy from ISP tracking.
- Accessing content restricted in your country.
