The appeal of a free VPN is obvious — who wants to pay for something when there’s a free version? But free VPNs and paid VPNs are not the same product with the same features. In many cases they’re fundamentally different in how they make money, which changes everything about how they handle your data.
Short answer: Most free VPNs make money by logging and selling your browsing data — the opposite of why you’d want a VPN. The exceptions are ProtonVPN Free (unlimited data, slower speeds) and Windscribe (10GB/month). For anything beyond basic privacy on a budget, a paid VPN starting from $2–3/month delivers dramatically better speed, security, and streaming support.
How free VPNs actually make money
Running a VPN requires servers in dozens of countries, bandwidth, engineering staff, and security infrastructure. That costs real money. A free VPN that never charges users has to cover those costs somehow. The common revenue models for free VPNs:
- Selling user data: Logging your browsing history and selling it to advertisers or data brokers. This is the most common model and directly contradicts the purpose of a VPN.
- Injecting ads: Inserting adverts into unencrypted web traffic. Several free VPN apps have been caught doing this.
- Selling bandwidth: Some free VPNs route paid customers’ traffic through your device and internet connection — essentially making your bandwidth available to others without your knowledge. Hola VPN is the most notorious example.
- Freemium upsell: The legitimate model — free tier to attract users, revenue from paid upgrades. ProtonVPN and Windscribe use this model and are trustworthy.
What free VPNs typically limit
Even legitimate freemium VPNs restrict their free tier significantly:
- Speed: Free servers are usually slower — more users per server, deprioritised bandwidth
- Server locations: 3–5 countries instead of 60+
- Data cap: 500MB/month to 10GB/month (ProtonVPN Free is the only unlimited option)
- Streaming: Free tiers almost never unblock Netflix, Disney+, or BBC iPlayer
- Device limit: Usually 1 device on the free tier
- No kill switch: Many free apps skip safety features
- Customer support: Paid users get priority; free users get limited help
What you get with a paid VPN
At $2–6/month on a 2-year plan, paid VPNs like NordVPN, Surfshark, and ExpressVPN offer:
- Full server network: 3,000–7,000 servers in 60–111 countries
- WireGuard protocol: Fast, battery-efficient, reliable reconnect
- Verified no-logs policy: Independent security audits confirming no data storage
- Netflix and streaming: Reliable unblocking of major platforms
- Kill switch: Blocks traffic if VPN drops — essential for real privacy
- Multi-device: 8–unlimited simultaneous connections
- Ad and malware blocking: Built-in DNS-level protection
- Customer support: 24/7 live chat
The only trustworthy free VPNs:
ProtonVPN Free — unlimited data, 3 server locations (US/NL/JP), slower speeds. No streaming. protonvpn.com
Windscribe Free — 10GB/month, servers in 10+ countries, decent speeds. Limited streaming. windscribe.com
Everything else in the “free VPN” category has serious privacy concerns.
The real cost comparison
The cheapest reputable paid VPN — Surfshark at around $2.29/month on a 2-year plan — costs less than a coffee per month. Over 2 years that’s roughly $55 total, prepaid. In exchange you get unlimited devices, 3,200+ servers, Netflix support, WireGuard speed, and audited privacy. ProtonVPN Free is genuinely free but comes with real speed and location limitations. Windscribe’s free 10GB/month is fine for light public WiFi use. For anyone who will use a VPN regularly — for streaming, travel, or daily privacy — the paid tier is worth it at these prices.
Free VPN red flags — what to avoid
Avoid any free VPN that:
- Has no verifiable privacy policy or company behind it
- Is based in China or a country with mandatory data retention and poor privacy laws
- Has never been independently audited
- Asks for excessive permissions (access to contacts, SMS, device ID)
- Has tens of millions of installs but no clear revenue model
- Includes names like “Super”, “Turbo”, “Master”, “Flash” — these are consistently problematic categories
Warning: Multiple security researchers have documented free VPN apps that route user traffic through other users’ devices (botnet behaviour), inject ads into HTTP traffic, and sell browsing data to third parties. The free VPN space is one of the most misleading categories in consumer software — the name “VPN” suggests privacy, but many free versions deliver the opposite.
When free is enough
ProtonVPN Free covers you if you only need a VPN occasionally — for public WiFi protection when travelling, for example — and you’re not trying to stream content or need fast speeds. Windscribe’s 10GB free tier is enough for a few sessions of secure browsing per month. If you’re a student on a tight budget, these are legitimate options. Just go in knowing the limitations.
How to choose — quick decision checklist:
- ✅ Need Netflix or streaming? → Paid only (ProtonVPN paid or NordVPN/Surfshark)
- ✅ Only need occasional public WiFi protection? → ProtonVPN Free works
- ✅ Budget under $3/month? → Surfshark or Private Internet Access
- ✅ Maximum privacy? → Mullvad (€5/month flat) or ProtonVPN paid
- ✅ Covering multiple devices? → Surfshark (unlimited) or PIA (unlimited)
- ✅ Travelling to restricted countries? → ExpressVPN — only one that reliably works
Frequently asked questions
Is ProtonVPN Free actually safe?
Yes — ProtonVPN is run by the team behind ProtonMail, is based in Switzerland, is open source, and has been independently audited. The free tier uses the same infrastructure and privacy standards as the paid tier. The limitations are speed and server selection, not privacy.
Why is Windscribe giving away 10GB for free?
Windscribe uses the freemium model — the free tier attracts users who may upgrade to paid. Their business is viable on paid subscriptions, not on selling free users’ data. Windscribe has been transparent about their privacy practices and is generally considered trustworthy among security researchers.
Can a free VPN protect me on public WiFi?
ProtonVPN Free and Windscribe Free will encrypt your traffic on public WiFi, which is their main legitimate use case. The speed and server limitations matter less when you just need basic security at a café. For more on public WiFi safety, see our guide to VPNs on hotel and public WiFi.
What’s the cheapest paid VPN worth using?
Private Internet Access at around $2.03/month (3-year plan) and Surfshark at around $2.29/month (2-year plan) are the most affordable reputable paid VPNs. Both have unlimited device connections, WireGuard support, and audited privacy policies. Our NordVPN vs Surfshark comparison covers the mid-range options in detail. Not sure which fits your needs?

The bottom line
Most free VPNs are not safe — they monetise your data in ways that defeat the purpose. The two legitimate exceptions (ProtonVPN Free and Windscribe) cover occasional use but aren’t suitable for streaming or daily privacy. At $2–3/month, paid VPNs like Surfshark are affordable enough that the free tier tradeoffs aren’t worth it for most people. New to VPNs? Start with our plain-English guide to what a VPN actually does.
