A VPN (virtual private network) encrypts your traffic and sends it through an intermediary server. That tunnel hides your real IP from the sites you visit and protects data on open WiFi networks. The useful question isn’t what it is, but which provider solves your specific case without selling you smoke.
The market is divided into three layers. The first is paid: CyberGhost, ExpressVPN, NordVPN, Surfshark, and Mullvad VPN compete on speed, number of countries, and independent audits. Mullvad stands out for accepting cash and not asking for an email; NordVPN and Surfshark for their price-to-device-count ratio; CyberGhost for preconfigured profiles for streaming. ExpressVPN usually wins on connection stability, although its price is higher.
The second layer is free. Proton VPN Free and Urban VPN let you try without a card, but with limits: scarce servers, lower speed, and, in some cases, business models based on aggregated data. A free VPN for PC or free VPN for iPhone works for occasional tasks, not for torrents or for working eight hours. Kaspersky and Opera integrate their own solutions: the browser one only covers that browser, not the entire system.
The third layer is extensions. A Chrome VPN or VPN extension is convenient, but it’s worth checking whether it’s a disguised proxy. A proxy VPN doesn’t encrypt the same way as a real tunnel, so don’t confuse them.
In the academic sphere, their own acronyms appear: UCM VPN, UPM VPN, and GlobalProtect VPN (Palo Alto) allow students and employees to access internal resources from home. They aren’t commercial services: they’re configured with the institution’s credentials and usually require two-factor authentication.
Before choosing, define your use. For traveling and avoiding geographic blocks, prioritize countries and speed. For strict privacy, look for an audited no-logs policy and anonymous payment. For mobile, check battery consumption. And remember: no VPN replaces common sense, a password manager, or HTTPS.
