We always recommend using a VPN—no question about it. There are plenty of good reasons to have one, especially if you care about keeping your online activity private.
But here’s the part most people don’t realize: not all VPNs are actually worth using. In fact, some are so bad that you’d be better off not using one at all than trusting them with your data.
That’s why it’s important to know what to watch out for. Below are a few red flags to keep in mind—along with specific VPNs to avoid if protecting your privacy really matters to you.
What Actually Makes a VPN Dangerous? (Most People Miss This)
Before we even get into specific VPNs to avoid, it helps to understand why some of them are risky in the first place. Because here’s the truth—most bad VPNs don’t look bad on the surface. They look polished, trustworthy, and full of promises.
But when you peel back the layers, that’s where the problems start to show.
1. Sketchy Terms of Service
Let’s be honest—no one really reads terms of service. Most of us just scroll to the bottom and click “agree.”
But when it comes to VPNs, that’s where some of the most important details are hiding.
A VPN’s terms of service spell out exactly what they track, what they don’t, and what they’re allowed to do with your data. And sometimes, buried in that fine print, you’ll find things like data collection, connection logging, or sharing information with third parties.
There’s also a simple rule to keep in mind: if a VPN can block or manage your account, it usually means they have some way of identifying you. And that often involves logging something.
So while it might not be exciting reading, the terms of service can tell you a lot about whether a VPN is actually protecting you—or quietly covering its tracks.
2. IP & DNS Leak Failures
This one is a big deal—and surprisingly common.
A VPN is supposed to hide your real IP address. But sometimes, due to connection issues or poor design, your real information can “leak” outside the VPN tunnel.
This can happen during everyday situations—like when your device goes to sleep, switches networks, or briefly disconnects.
When that happens, your real IP address can be exposed without you even realizing it.
And here’s the scary part: even a single leak defeats the entire purpose of using a VPN. It only takes one moment of exposure to reveal who you are and where you’re browsing from.
That’s why reliable VPNs include leak protection and tools like kill switches—but not all of them do.
3. Risky Country of Origin
This is one of those things most people never think about—but it matters more than you’d expect.
Every VPN company is based somewhere, and that location determines the laws they have to follow. According to the document, certain countries—often referred to as the “Five Eyes,” “Nine Eyes,” and “Fourteen Eyes”—have agreements to share intelligence and surveillance data with each other.
That means if your VPN operates in one of these countries (like the U.S., UK, or Australia), there’s a chance your data could be requested—or even quietly monitored—by authorities.
So even if a VPN says it protects your privacy, the laws of the country it operates in might tell a different story. And in some cases, companies are legally required to comply.
The takeaway? Where your VPN is based isn’t just a small detail—it can determine how private your data really is.
4. No Anonymous Payment Options
This is something a lot of people overlook—but it can matter if you’re serious about privacy.
When you sign up for a VPN using a credit card or PayPal, you’re tying your identity directly to that account. Even if the VPN itself is secure, your payment method creates a clear link back to you.
Some VPNs offer anonymous payment options like cryptocurrency, which don’t leave the same kind of trail.
Now, not everyone needs that level of anonymity—but it’s worth thinking about. Because if your goal is to stay private, every piece of identifying information adds up.
And sometimes, it’s not just about what the VPN protects—it’s about what you give away before you even log in.
5. Free VPN Trap
Free sounds great… until you realize how those services actually make money.
Free VPNs still have to pay for servers, bandwidth, and maintenance. So if you’re not paying, they have to make money somewhere else.
And most of the time, that “somewhere else” is you.
That can mean selling your data, injecting ads, or even using your connection as part of a larger network (like we saw with Hola). Some services might also limit your speed or track your activity to monetize it later.
It’s the classic trade-off: you save money upfront, but you may be paying with your privacy instead.
6. Weak Encryption and Outdated Protocols
Not all VPNs are built with the same level of security—and this is where things can get technical, but it’s worth understanding the basics.
VPNs rely on protocols to encrypt your data. Some older ones like PPTP and L2TP are still used because they’re fast—but they come with known weaknesses.
On the other hand, modern protocols like OpenVPN are considered much more secure because they’re open-source and constantly tested for vulnerabilities.
Think of it like locking your front door. Older protocols are like using a flimsy lock—easy to break if someone really tries. Strong protocols are like a reinforced deadbolt.
If a VPN is still relying on outdated technology, it might not matter how good their marketing sounds—the protection just isn’t there.
7. Logging Your Activity (Even When They Say They Don’t)
A lot of VPNs love to advertise “no logs.” It sounds reassuring, right? Like everything you do disappears the moment you disconnect.
But it’s not always that simple.
Some VPNs keep “minimal logs”—things like your IP address or connection times—while others may track much more, including browsing habits and websites visited.
Here’s the problem: even small pieces of data can be enough to identify you when combined. So while a VPN might technically not log everything, it could still log enough.
And that’s why “no-logs” claims can be misleading. Some companies don’t log browsing activity—but still collect connection data. Others use vague language that sounds privacy-friendly without being fully transparent.
At the end of the day, if a VPN is keeping records of your activity in any form, there’s always a chance it could be traced back to you.
8 Dangerous VPNs That Could Destroy Your Privacy
It’s one thing to guess whether a VPN is safe based on what it claims to do. It’s a completely different story when a service gets caught actually tracking users, keeping logs, or even selling their data.
If you truly care about your privacy, it’s worth paying attention to the ones that have already crossed that line. Here are the VPNs experts say to avoid—services that have been proven, one way or another, to put user privacy at risk.
1. Opera Free VPN
Opera’s free VPN sounds like a dream, doesn’t it? Unlimited, built right into your browser, and completely free. But here’s where things get a little misleading.
Expert say that Opera Free VPN isn’t really a true VPN in the traditional sense—it’s closer to a proxy. That might not sound like a big deal, but the difference matters. A full VPN encrypts and routes all your internet traffic, while a proxy typically offers more limited protection.
On top of that, Opera does collect usage data, which may be shared with third parties. And once again, that creates a disconnect. You’re using something labeled as a “VPN” for privacy… while it may still be tracking aspects of your activity.
It’s not that Opera is trying to trick users outright—but the branding can definitely give a false sense of security. And when it comes to something as important as your privacy, “almost” protection isn’t really enough.
2. HideMyAss
HideMyAss is one of those VPN names that sounds bold and reassuring—like it’s built specifically to protect you no matter what. But when you dig into what actually happened, the story becomes a lot less comforting.
In a well-known case, authorities were able to obtain activity logs from HideMyAss and use them to identify and track down a user. Now, to be clear, the person involved had committed a crime—but that’s not really the point. The bigger takeaway is this: the VPN had logs that could be traced back to a real individual.
And that’s where the trust issue comes in. Many people use VPNs believing their activity is completely private and untraceable. But this situation showed that, despite privacy-focused branding, some services still keep enough data to connect the dots. It’s a reminder that “privacy” isn’t just about what a company says—it’s about what they actually store behind the scenes.
If there’s one lesson here, it’s this: never assume a VPN is log-free just because it claims to be. When it comes to your personal data, assumptions can cost you.
3. VPNSecure
VPN Secure might not be as widely talked about as some of the others, but that doesn’t mean it’s off the hook when it comes to privacy concerns. In fact, when you look at the details, there are a few things that should make you pause.
For starters, the service has been linked to IP and DNS leaks, according to this research paper—meaning your real identity could be exposed even while you think you’re protected. And that’s a pretty big deal because even one leak can completely defeat the purpose of using a VPN in the first place.
On top of that, VPN Secure is based in Australia, which is part of the “Five Eyes” surveillance alliance. That means there’s a higher chance that user data could be accessed or shared between governments. Even if the company has good intentions, the jurisdiction it operates in adds an extra layer of risk.
There are also concerns around how user connections might be structured—particularly the idea of “egress points,” which can function similarly to exit nodes. If that sounds familiar, it’s because it echoes the same kind of setup that caused serious issues with services like Hola.
Put it all together, and VPN Secure starts to feel less like a safe haven… and more like a gamble.
4. Hotspot Shield
Hotspot Shield is one of those VPNs that feels familiar and widely used, which can make it seem trustworthy by default. But when you look at the details, there are some serious concerns worth paying attention to.
There were allegations that Hotspot Shield intercepted user traffic and redirected it to partner websites, including advertisers. That means instead of simply protecting your browsing, it may have been quietly influencing it.
There were also claims that the service logged connection details—something that goes directly against what many users expect from a VPN. Even more concerning, earlier research found behavior like injecting JavaScript into webpages and redirecting e-commerce traffic.
Now, whether every user experienced this or not isn’t really the point. The bigger issue is trust. When you’re using a VPN, you’re handing over a huge amount of control—you’re trusting that service with all your internet traffic.
And if there’s even a chance that traffic is being monitored, redirected, or monetized, that trust starts to break down pretty quickly.
5. Facebook Onavo VPN
At first glance, Facebook’s Onavo VPN sounded like a helpful built-in feature—something designed to “protect” your data while using mobile apps. But when you look a little closer, it becomes clear that privacy wasn’t really the goal.
According to the experts, Facebook’s “Protect” feature was essentially just Onavo VPN in disguise, a service Facebook had acquired earlier. And instead of simply securing your connection, Onavo was collecting data about how you used apps on your phone.
Think about that for a second. The very tool you might trust to keep your activity private was actually monitoring it—tracking which apps you use, how often, and in what ways. That data could then be used to “improve services,” but also to give Facebook deeper insights into user behavior.
So while it may have looked like a security feature, Onavo functioned more like a research tool. And that flips the whole idea of a VPN on its head. Instead of protecting your privacy, it was quietly studying it.
6. PureVPN
PureVPN is a perfect example of why you can’t just take “no-logs” claims at face value.
The service advertised itself as a no-logging VPN, meaning your activity shouldn’t be recorded or traceable. But there was a case where information from PureVPN was used by authorities to identify a suspect.
Again, the individual involved was accused of wrongdoing—but that’s not the core issue here. The real concern is that despite promising not to keep logs, the service had enough data to connect a user to specific activity.
That creates a pretty uncomfortable question: what does “no logs” actually mean?
For many users, it implies total anonymity. But in reality, some VPNs may still store certain connection details—just enough to piece things together if needed. And unless you dig deep into their policies, you might never realize the difference.
PureVPN’s case is a powerful reminder that words like “no-logs” can sound reassuring… but they don’t always tell the full story.
7. ZenMate
ZenMate is another VPN that, on the surface, seems perfectly fine—easy to use, widely available, and marketed as a simple way to stay private online. But when experts started testing it, some cracks began to show.
According to a test by vpnMentor, ZenMate was found to suffer from IP leaks during testing. And that’s one of the worst things that can happen with a VPN. If your real IP address is exposed, then your identity and location can still be traced—even if you think you’re browsing anonymously.
What makes things more concerning is how the company responded. The report noted that ZenMate was slow to address these vulnerabilities. And in the world of cybersecurity, speed matters. The longer an issue goes unresolved, the longer users remain exposed without even realizing it.
It’s not just about the leak itself—it’s about trust. When a VPN has a known issue, you want to feel confident that the company is actively working to fix it and protect its users.
With ZenMate, that hesitation raises a bigger question: if something goes wrong, can you rely on them to have your back?
8. Hola VPN
Hola VPN might seem like a clever, free shortcut to privacy—but once you understand how it actually works, it quickly becomes one of the riskiest options out there.
Instead of using secure, dedicated servers like most VPNs, Hola turns its users into part of the network. In simple terms, your device can become an “exit node,” meaning other people’s internet traffic can be routed through your connection.
That’s where things get uncomfortable. Because if someone else is using your IP address to browse—or worse—you’re the one it traces back to. You don’t know who’s using your connection or what they’re doing with it.
And it doesn’t stop there. Hola has also been found to sell users’ bandwidth to third parties. So not only are you sharing your connection, but the company is profiting from it behind the scenes.
When you step back, it flips the whole idea of a VPN. Instead of protecting you, it’s using you. And that’s why experts don’t just suggest avoiding Hola—they strongly warn against it.
