Dangers of Using a VPN: Here’s All You Should Know [Guide]

Most of what you hear about VPNs is positive: they provide encryption, online privacy, device security, etc. While virtual private networks do come with a ton of benefits, they’re not always perfect at what they do. There are, in fact, some dangers of using a virtual private network. Below we discuss these issues and give tips on how to stay safe both with and without a VPN.

Basics of VPNs

VPNs provide online privacy and digital anonymity, making them ideally suited for staying safe online. They can also defeat internet fast lanes introduced by broken net neutrality laws, all thanks to a few handy features.

Encryption and Virtual IP Addresses

VPNs provide several unique features to keep you safe online. Two of the most important are encryption and virtual IP addresses.

Encryption locks data in a layer of unbreakable code. With this in place, your information becomes unreadable to third parties, including cyber criminals, government agencies, and ISPs. No one can see what you’re downloading, or which websites you’re visiting with a VPN in place.

With a VPN, you also gain access to virtual, non-local IP addresses. This effectively makes you invisible online, as no one can tell where you’re really located or who you are.

Both of these features work together to provide online security on any device you use. When they do their job, you can stay safe no matter where you are, how you connect to the internet, nor what you do online.

Logging Policies

One of the big selling points you’ll see for many VPNs are the particulars of their logging policy. Most of the time you’ll see things like “zero-logging policy” or “no logging policy on traffic”. What this means is simply that the VPN doesn’t keep activity records on what its users are doing while connected to their service.

Each time you log onto a VPN server, you agree to send your traffic through those devices. Since the VPN can decrypt information packets (it’s necessary for the service to function), it’s possible that the VPN company can store logs detailing what sites or which files are downloaded by which account. If you’re concerned about your privacy, you want a zero-logging policy to ensure none of this information is ever stored long-term.

Free vs Paid VPNs

One of the central dangers of using a VPN is choosing the wrong one. Free services that advertise on browser extension stores and mobile marketplaces are notorious for claiming fast downloads and anonymized activities when in reality they can be more dangerous than not using a VPN at all.

If a VPN service doesn’t charge its customers, the company has to bring in revenue from somewhere else. The most common source is selling user information the VPN promised to protect. If you aren’t paying for the service, you’re not the customer, you’re the product. This holds true for nearly every free VPN service. It’s always best to stick with trusted and reliable paid sources to ensure your information stays as secure as possible at all times.

VPN Limitations

VPNs are incredibly useful and powerful tools, but they can’t do everything. They’re best used to secure data that leaves your device. What happens on your computer isn’t usually affected by a VPN, which is why firewalls and virus protection are still crucial.

  • All devices aren’t automatically protected – If you use VPN software to protect your PC or smartphone, that’s the only device that gets protected. In order to keep data safe, you must install an app on every device that connects to the internet (or else use a VPN router).
  • Viruses and malware are still a threat – Most VPNs do not protect your computer from viruses or malware. You’ll still need to be mindful of downloading suspicious files, especially through torrent and P2P networks.
  • Speed issues – VPN will often slow your connection speed by 10-25% depending on the service, all thanks to encryption overhead. This can be frustrating if you frequently stream HD movies or do a lot of online gaming.

Dangers of Using a VPN

Now that you know how VPNs work, it’s time to learn how they can be abused. In general, if you can find a reliable, paid VPN service, you won’t have to worry about any of the dangers listed below. It’s always good to keep an eye out for these problems, though, as when it comes to online privacy, you can never be too vigilant.

Can You Trust a VPN?

How do you know you can trust your VPN to actually keep your data safe? When it comes down to it, you can’t. There are very few external security audits that take place on VPN services, meaning there’s no way to verify with 100% certainty that a company follows through with all of its promises.

Even if a VPN says it provides bulletproof security, even if it claims zero-logging on everything, you can never be sure. You’re sending your data through a third party, after all, which involves at least a little trust.

IP Logging

The core of any VPN’s privacy features is always its logging policy. Most services claim zero-logs in as many areas as possible. While it’s great to promise this, what’s to stop a VPN from storing data anyway? Very little, it turns out, which means a zero-logging policy on a disreputable VPN is practically useless.


Where precisely in the world a VPN is registered makes a huge difference in how secure it is. For example, even if a VPN advertises a strict zero-logging policy, if they’re located in a country whose government requires laws, the VPN can be forced to store user information in secret. In this case, it doesn’t matter what the VPN’s policy is, your data can be compromised.

Traffic Restrictions

Although it’s not as dangerous as IP logging or being generally untrustworthy, VPNs have often been caught artificially throttling or blocking traffic of its users. This most commonly presents as firewalls that prevent P2P network access or torrent downloads, both of which can slow down an entire VPN’s service based on the nature of the connection. Occasionally, though, VPNs will cripple a connection if a user downloads or streams too much.

How to Get a Good VPN that Isn’t Dangerous

Although there can be certain dangers to using a VPN, that doesn’t mean they’re all bad. Finding a good quality VPN still provides a ton of useful features that can help keep you safe online. To make sure you don’t regret your VPN purchase, we’ve provided a handful of recommendations below, along with useful criteria to evaluate a VPN on your own.

How to Choose a VPN

You don’t have to be a computer expert to choose a VPN. Companies go to great lengths to make sure their VPN is easy to install and to use on a variety of devices, including smartphones and PCs. In most cases you can connect with just a few clicks, no configuration required.

Finding the right VPN takes a little work. We’ve made that easier by providing a list of the most important criteria for selecting a VPN. Keep reading and you’ll be surfing safely in no time.

  • Fast speeds – VPNs can be slower than a standard internet connection. Make sure your VPN compensates with top speed servers!
  • Privacy and security – Stronger encryption and privacy policies means a better online experience.
  • Server network – In order to get a specific IP address, your VPN has to have servers located inside that country.
  • Zero-logging policy – Your information can only stay secure if the VPN has a strict zero-logging policy.
