Free VPNs range from genuinely useful limited-tier services from reputable providers to data-harvesting products that are more dangerous than no VPN at all. Here is how to tell the difference and which ones are worth using.
The Problem with Most Free VPNs
Running VPN infrastructure costs money. If a VPN is entirely free with no premium tier, the business model is usually selling user data (browsing history, IP address, device fingerprint) to advertisers or data brokers. The 2021 investigation by vpnpro.com found that dozens of popular free VPN apps in the App Store and Play Store shared data with third parties or had direct Chinese corporate ownership. Free VPNs to avoid: Hola VPN (your device becomes an exit node for other users), TurboVPN and SuperVPN (data sharing concerns documented in multiple investigations), and any VPN with no clear corporate ownership or privacy policy.
Legitimate Free VPN Tiers
ProtonVPN Free: unlimited data but limited to one device and three server locations (Netherlands, US, Japan). No logs, open-source client, based in Switzerland. The best free VPN option for most users. Windscribe Free: 10GB/month data limit, 10+ server locations, no-logs policy, Canadian company. Mullvad: not free but accepts anonymous payment methods (cash, crypto) and requires no email to sign up -- the most privacy-preserving paid option. Cloudflare WARP: free, fast, but designed primarily for DNS privacy rather than full traffic anonymization -- does not hide your IP from websites.
When to Pay
If you need: more than 10GB/month of data, server selection for unblocking streaming services, or simultaneous protection on multiple devices -- a paid VPN at EUR 3-6/month is the practical answer. ProtonVPN Plus, Mullvad, and Surfshark are the strongest value options at that price range.
