What Is a VPN and Do You Need One?
A VPN, or virtual private network, sends your internet traffic through an encrypted connection to a server run by the VPN provider. It is often advertised as a cure-all for online privacy, but it solves only some problems.
What a VPN does
- Encrypts traffic between your device and the VPN server
- Hides your real IP address from the websites you visit
- Helps protect you on public Wi-Fi from other people on the same network
What a VPN does not do
- It does not make you anonymous: the VPN provider can still see your traffic
- It does not protect you from phishing or malware
- It does not stop websites from tracking you with accounts and cookies
When a VPN is useful
A VPN makes sense if you often use public Wi-Fi in cafes, airports or hotels, or if you want to keep your browsing private from your internet provider. Some people also use one while traveling to reach services from their home country.
When you probably do not need one
If you mostly browse on your home network, use secure websites and keep your devices updated, a VPN adds little. Strong passwords and two-factor authentication matter more.
How to choose a provider
- Look for a clear privacy policy about what is logged
- Prefer independent audits when available
- Be careful with free VPNs, since they need to make money somehow
- Check the price after the introductory period
A VPN is one tool among several. Combine it with a password manager and two-factor authentication for better protection.
