Are Free VPNs Safe? What to Know Before You Download One

A free virtual private network (VPN) sounds like an easy win: you get more privacy online without paying a monthly subscription. It's a popular choice, too: 46% of VPN users rely on a free service, according to our VPN consumer report. 

But are free VPNs safe? The answer depends entirely on the provider. While some reputable VPN companies offer secure free plans, others make money in ways that could put your privacy at risk.

If you're trying to decide whether a free VPN is worth downloading, this guide explains what to look for, the biggest risks to avoid, and when paying for a VPN is the smarter choice. If you're still comparing providers, our guide to the best VPN services can help you find trustworthy options.

Are free VPNs safe to use?

Some free VPNs are safe to use, but many aren't.

The biggest difference comes down to how the company makes money. Running a VPN costs money because providers have to maintain servers, develop apps, and keep security systems up to date. If a company isn't charging customers, it has to generate revenue another way.

Reputable providers often use their free plans to introduce people to their paid service. Less trustworthy companies may log your browsing activity, collect and sell your personal information, or display aggressive advertising to cover operating costs.

That doesn't mean you should avoid every free VPN. Instead, it's important to understand the trade-offs, recognize warning signs, and choose providers with a strong reputation for protecting user privacy.

Why free VPNs can be risky

Not every free VPN puts your privacy at risk, but there are several common issues worth watching for.

• Your data may be logged or sold. Some providers collect information about your browsing habits, device, or location and sell it to advertisers or data brokers. According to our VPN consumer report, 56% of survey respondents didn't realize many free VPNs may fund their services by logging and selling user data.
• Security may be weaker. A trustworthy VPN encrypts your internet traffic using modern standards such as AES-256 (Advanced Encryption Standard with a 256-bit key), helping keep your data private. Some free VPNs use weaker encryption or fail to clearly explain how they protect your data.
• Your real IP address could leak. A poorly designed VPN may inadvertently expose your IP address via DNS or WebRTC leaks, undermining the privacy benefits you expect. If you're unsure what information a VPN actually protects, learn more about what a VPN hides.
• Usage limits can be frustrating. Many free services restrict monthly data, throttle connection speeds, or offer only a handful of servers. These limits may not be a security risk, but they can make the VPN less useful for everyday browsing or streaming.
• Ads and bundled software can create additional risks. Some lesser-known VPN apps rely heavily on advertising or bundle unwanted software with their downloads. In extreme cases, security researchers have found malicious apps posing as VPNs.
• Mobile apps can over-ask for permissions. Many free VPNs are downloaded as phone apps, and some request access to far more than they need — your location, contacts, or device storage. Sketchy free VPN apps have made it onto the Apple App Store and Google Play with invasive permissions or hidden trackers, so check what an app is asking for before you install it.

Privacy experts echo this. As Peter Swire, J.Z. Liang Chair at Georgia Tech's School of Cybersecurity & Privacy, warns: "Often, things that say 'free' are not actually free. Check the policy to see whether and in what ways the VPN accesses your own data when you use the VPN. Some VPNs are free in terms of money but collect your data instead, and possibly send that data on to data brokers or other third parties."

These risks don't apply to every provider, but they highlight why it's important to research a VPN before trusting it with your internet traffic. Our guide on whether VPNs are safe explains more about the privacy protections a trustworthy VPN should provide.

How to tell if a free VPN is safe

A little research can help you separate trustworthy providers from risky ones. 

Look for these 5 green flags:li

1. A clear no-logs policy. This means the provider says it doesn't collect or store information about your online activity. Even better, look for companies whose policies have been independently audited.
2. Strong encryption. Reputable VPNs typically use AES-256 encryption and secure VPN protocols such as WireGuard or OpenVPN.
3. A transparent business model. Established VPN companies usually explain how their free plans are funded. In many cases, the free version is simply a limited tier designed to encourage upgrades.
4. A solid reputation. Look for providers with a track record of protecting customer privacy, rather than companies with little information about who owns or operates the service.
5. Reasonable limitations. Data caps, fewer servers, or slower speeds are common on legitimate free plans. Those restrictions are generally preferable to providers that offer "unlimited everything" without explaining how they stay in business.

In general, the safest free VPNs are the free versions offered by reputable paid VPN companies, rather than standalone apps that promise unlimited service with no clear revenue model. Learn more about how VPNs work.

Which free VPNs are the safest?

We've conducted rigorous independent testing and found that the safest free VPNs share the same traits: a clear, audited no-logs policy, strong encryption, and an honest way to fund the free tier. This is why the most trustworthy free plans tend to come from established providers rather than standalone "free" apps. 

Here are the picks that stand out:

• Proton VPN 
• Windscribe 
• TunnelBear 
• PrivadoVPN
• hide.me
• VeePN (free proxy) 

Even the best free tiers come with data caps and fewer servers. Free VPNs are fine for occasional Netflix streaming or light browsing, but a paid plan goes further.

Free VPNs to avoid

We’ve tested over 50 VPN services and found that some of the worst free VPNs are Turbo VPN, Betternet VPN, and WhoX VPN. Bad free VPNs have tells beyond collecting and selling your data or bombarding you with spammy ads.

Look for these 5 red flags:

1. The agent is flagged as malware and won't download.
2. Servers won’t connect and spin in limbo.
3. Internet speeds tank, making browsing impossible.
4. Lack of secure protocols and privacy features.
5. Known for leaking IP addresses.

We cover more free VPNs to avoid, like Hola, Hoxx VPN, and SuperVPN, in our roundup of the best free VPN alternatives. But remember that even paid VPNs (looking at you, SlickVPN) can be terrible, so keep that in mind while comparing providers.

Free vs. paid: Is a free VPN enough?

For many people, a free VPN is perfectly adequate for occasional use. If you mainly want extra privacy while using public Wi-Fi, checking your email at a coffee shop, or browsing more securely, a reputable free VPN can do the job. 

But paid VPNs usually go further, with better streaming support, higher or unlimited data allowances, and stronger customer support. They also tend to win on the fundamentals. As Gary Bertoline, a professor of engineering technology and computer & information technology at Purdue University, explains, four advantages stand out:

1. Faster speeds: Paid VPNs invest in better server infrastructure, reducing congestion and maintaining fast connections for streaming, gaming, and downloads.
2. More server locations: You get access to a larger network of global servers, helping with geo-unblocking and reducing latency.
3. Stronger security: Paid VPNs typically offer robust encryption (AES-256), secure protocols (WireGuard, OpenVPN), and features like a kill switch and DNS leak protection.
4. No-logging policies: Reputable paid VPNs have strict no-logs policies, meaning they don't track or store your browsing activity.

Those improvements often lead to a better overall experience. According to our VPN consumer report, 94% of paid VPN users reported being satisfied with their service, compared with 83% of free VPN users.

If privacy is especially important, or you use a VPN every day, a paid service is often worth the relatively low monthly cost. If you're still deciding, compare the best VPN services we’ve tested and ranked.

What to do if you've already used a sketchy free VPN

If you've used a free VPN you no longer trust, don't panic. A few quick steps will limit any damage:

1. Delete the app and any browser extension. Remove it from every device you installed it on.
2. Revoke its permissions. On your phone, check the app's permissions before (or while) uninstalling; on desktop, review any network or browser permissions it was granted.
3. Clear its cached data. Wipe any stored app or browser data so nothing lingers.
4. Run a malware scan. Some free VPNs have been caught bundling unwanted software, so scan your device with trusted antivirus software.
5. Change key passwords. If you logged into important accounts while connected, update those passwords (starting with email and banking) ideally with a password manager, and turn on two-factor authentication.
6. Switch to a vetted VPN provider. Replace it with a trustworthy option from our best VPNs list.

Going forward, watch for unusual account activity or a spike in spam, which can be signs your data was exposed.
