Quick Answer
Free VPNs make money by selling your data, injecting ads, distributing malware, or harvesting bandwidth. A 2020 study of 283 free Android VPNs found 38% contained malware, 75% used third-party tracking, and 18% did not encrypt traffic at all. Free VPNs also fail to bypass blocks in China, the UAE, and other restrictive countries because their server IPs are publicly known and consistently blocked. If you need a VPN for privacy, streaming, or VoIP unblocking, a paid service is the only reliable option.
“If you are not paying for the product, you are the product.” This is true for almost every free internet service, but it is dangerously true for free VPNs. The product VPNs are supposed to deliver — privacy and security — is exactly what free VPNs typically violate. This guide covers the documented risks of free VPNs, why they fail in restrictive countries, and what the actual cost difference is compared to a paid service.
The Five Ways Free VPNs Make Money
Running a VPN service costs money — servers, bandwidth, software development, customer support. Free VPNs cover those costs through one or more of these methods:
1. Selling user data. Browsing history, app usage patterns, and location data are sold to data brokers, advertisers, and analytics firms. The 2017 case of Hotspot Shield, which faced an FTC complaint for sharing user data despite advertising “anonymous browsing,” is one of many documented examples.
2. Injecting ads. Free VPNs inject ads into web pages you visit or display them within the VPN app. Some replace existing ads on websites with their own. This degrades performance, breaks websites, and exposes you to potentially malicious ad networks.
3. Distributing malware. A 2020 academic study of 283 Android VPN apps in the Google Play Store found that 38% contained malware or malicious code. The malware ranges from adware to credential-stealing trojans to cryptocurrency miners.
4. Selling bandwidth. Some free VPNs (notably Hola VPN) operate as peer-to-peer networks where free users’ devices are used as exit nodes for paying customers. Your internet connection gets used by strangers — potentially for illegal activity that traces back to you.
5. Harvesting credentials. Some malicious free VPNs intercept unencrypted traffic to steal login credentials, banking information, and personal data.
Documented Free VPN Incidents
This is not theoretical. Here are documented cases:
SuperVPN, GeckoVPN, ChatVPN (2021): A data breach exposed 21 million users’ credentials, including names, email addresses, and device IDs.
Hola VPN (2015–present): Used customers’ bandwidth as exit nodes for its paid sister service Luminati. User devices were used in DDoS attacks without their knowledge.
Hotspot Shield (2017): The Center for Democracy and Technology filed an FTC complaint alleging the service injected JavaScript code for advertising and tracking purposes despite marketing itself as a privacy tool.
Onavo Protect (Facebook, 2018): Removed from the Apple App Store after Apple determined Facebook was using it to collect data on user activity outside its own apps.
20Speed VPN (Iran, 2023): Bitdefender researchers found this popular Iran-based free VPN was distributing spyware. Iranian users seeking privacy were getting the opposite.
SuperVPN Free VPN Client (2020): Removed from Google Play after security researchers documented it was vulnerable to man-in-the-middle attacks that could intercept user traffic.
Why Free VPNs Fail in Restrictive Countries
Beyond the privacy issues, free VPNs also fail technically in the places where you most need a VPN:
Server IPs are public knowledge. Free VPNs have a small pool of servers serving millions of users. Those IPs are well-documented and added to government blocklists in China, UAE, Saudi Arabia, Iran, and Russia. The free VPN that worked at home will not connect once you arrive.
No obfuscation. Bypassing the Great Firewall or Iranian DPI requires obfuscation (stealth mode). Free VPNs do not include this — it is bandwidth-intensive and requires ongoing development.
Streaming detection. Netflix, BBC iPlayer, and Disney+ have permanent blacklists of every known free VPN IP. Free VPNs cannot bypass streaming geo-blocks.
Bandwidth throttling. Most free VPNs cap data at 500 MB to 10 GB per month. Hulu, Netflix, or any HD streaming exceeds this in a single evening.

The Real Cost Difference
People assume free VPNs save them money. The actual gap is small.
A reasonable paid VPN runs $3–8 per month on annual plans — about 10–25 cents per day. For that, you get: real encryption, no data sales, working obfuscation for restrictive countries, streaming-optimised servers, no bandwidth caps, customer support, and no malware risk. The cost of identity theft from a malicious free VPN can run thousands of dollars and take years to resolve.
If you need a VPN to make WhatsApp calls in Dubai, stream Netflix while travelling, or maintain privacy on hotel WiFi, the math is obvious. A free VPN that fails to do those jobs and harvests your data costs you more than $0.
What to Look For in a Paid VPN
Not every paid VPN is trustworthy. The key things to verify:
- No-logs policy — ideally audited by a third party
- Jurisdiction outside Five Eyes / Fourteen Eyes — countries that participate in surveillance sharing agreements
- Working obfuscation if you need it for China, Iran, or the UAE
- Reasonable server count — large pool with rotating IPs for streaming
- Refund policy — 30-day money-back guarantees are standard among reputable providers
- Transparent ownership — you should be able to find out who owns the company
Frequently Asked Questions
Are all free VPNs dangerous?
Not all, but most. Some legitimate VPN providers offer free tiers with limited features as a marketing funnel for paid plans. These are usually safe but very limited. Standalone free VPN apps with no paid version are the dangerous category — they have no other revenue source besides exploiting users.
Can free VPNs unblock Netflix?
Almost never. Netflix maintains blacklists of every known free VPN server IP. Even when a connection succeeds, bandwidth limits prevent HD streaming.
Will a free VPN work in the UAE for WhatsApp calls?
Free VPNs in the UAE typically fail. Etisalat (e&) and du have detection systems that identify and block known free VPN servers. UAE VPN access requires a paid service with rotating IPs.
Are browser-based free VPN extensions safe?
Browser extensions like Hola, TouchVPN, and similar are technically proxies, not VPNs. They only protect browser traffic, not other apps, and most have documented privacy issues. They are generally less safe than free VPN apps and offer less protection.
What about free VPNs from well-known names like Opera or Google?
Opera VPN has had documented privacy concerns. Google One VPN logs connections to Google’s infrastructure (it is not anonymous from Google itself). Free VPNs from major companies tend to be safer than fly-by-night apps but still have business models that may conflict with user privacy.
What if I just need a VPN for an hour to access one site?
If you only need it occasionally, look at paid services with monthly billing or short trial periods rather than free apps. The cost of a single month is typically under $10 — less than the value of one stolen credit card.
