Choosing a VPN today isn’t about downloading the first free app that shows up in the store. It’s about understanding what happens to your data when you connect to a public network, what limits «free» hides, and when it’s worth paying. Here’s a practical guide to help you decide with good judgment.
What a VPN is and what it isn’t
A VPN creates an encrypted tunnel between your device and a remote server. Your internet provider stops seeing which websites you visit; the website you visit sees the server’s IP, not yours. That’s it. It doesn’t make you anonymous by magic, nor does it replace an antivirus. If someone promises total invisibility, be suspicious.
Free vs. paid: where’s the catch
Free options (Proton VPN Free, Urban VPN, Chrome or Firefox extensions) usually limit speed, servers, or data. Some fund the service with advertising or browsing data. Proton VPN free stands out because it doesn’t limit volume, although it reduces speed and available countries. For occasional use on your phone it’s fine; for working daily or watching 4K streaming, it’s not.
In the paid segment, very different offerings coexist: NordVPN and Surfshark bet on speed and massive server networks; CyberGhost simplifies the choice with use-based profiles; ExpressVPN prioritizes ease of installation; Mullvad forgoes email and accepts cash payment, a radical privacy approach.
Corporate VPNs: GlobalProtect and university ones
Don’t confuse a consumer VPN with work or study ones. GlobalProtect (Palo Alto) is the client many companies use so their employees can access the intranet from home. The same goes for VPN UCM or VPN UPM: they’re institutional access points that require their own credentials and won’t work for watching Netflix in another country.
What to look at before subscribing
- Logging policy: make sure it’s audited by third parties.
- Protocol: WireGuard or similar performs better than OpenVPN on mobile.
- Leaks: check that your real IP and DNS aren’t leaking.
- Jurisdiction: it affects what data can be demanded from you.
- Devices: how many you can connect at once.
Common mistakes
Using a free VPN for online banking, installing extensions without reviewing permissions, or assuming a browser proxy is the same as a VPN. A proxy only changes your IP in the browser; it doesn’t encrypt all the traffic on your device. If you want real privacy on your PC, you need a full client, not an add-on.
The best VPN is the one that fits your use: a free and honest one for occasional lookups, a paid one with auditing for those who work away from home or travel frequently.
