What is a VPN?
A VPN (virtual private network) creates an encrypted tunnel between your device and a server, so your traffic is scrambled on the way and appears to come from the server instead of you.
What it actually does
- Encrypts your connection so others on the same network (like public Wi-Fi) cannot read what you send.
- Hides your IP address, showing the VPN server's location instead of yours.
What it does not do
- It does not make you anonymous — your accounts still identify you when you sign in.
- It does not replace antivirus or stop you from being phished.
- A free VPN can be worse than none if it logs or sells your data; choose a reputable, transparent provider.
When it helps
A VPN is most useful on public Wi-Fi, for privacy from your network or provider, and for accessing your home or work network remotely. For everyday browsing on a trusted connection, a modern browser with HTTPS already encrypts most of what matters.
Frequently asked questions
Do I really need a VPN?
Not always. It is valuable on public Wi-Fi and for privacy, but most websites already use HTTPS encryption. Decide based on your situation.
Are free VPNs safe?
Be careful. Some free VPNs log or sell your browsing data. If you use one, pick a reputable provider with a clear no-logs policy.
