In short
A VPN is not a general security product. It can help on untrusted Wi-Fi or to reach your home network, but protects neither against phishing nor malware.
What is it?
A VPN builds an encrypted tunnel between your device and a server. Websites then see the server's address instead of yours. The VPN provider, in turn, can see your traffic.
Who is it useful for?
People who often use public Wi-Fi or want to reach their home network while away.
What does it protect against?
- Eavesdropping on connection data in untrusted networks
- Partly websites tracking your IP address
What does it not protect against?
- Phishing, malware and account takeover
- Tracking through cookies and sign-ins
- A dubious VPN provider itself
What you can do for free
- 01Look for HTTPS – it is standard today
- 02Use mobile data rather than open Wi-Fi
- 03Check your router's VPN feature for home access
When is an extra product worth it?
A paid service can be worth it if you regularly use untrusted networks. Some free VPN apps make money from data – be careful.

Frequently asked questions
Do I need a VPN at home?
Usually not. On your own well-secured Wi-Fi a VPN adds little security.
Does a VPN protect online banking?
The connection to the bank is already encrypted. An up-to-date device and checking the correct address matter more.
