Using a good-quality VPN service is a reliable way to secure your privacy and maximize your freedom online. It’ll hide your IP address, encrypt your browsing activity, and let you unblock websites that are censored in your location.

But a VPN won’t solve all of your problems. It’s important to understand the limitations and disadvantages of using a VPN in order to keep yourself safe online.

Despite the clear benefits, a VPN isn’t a universal solution for all online privacy issues. Thinking it is could put you at risk.

In this guide, we explore the ten main downsides to using a VPN.

1. A VPN Will Not Make You Completely Anonymous

Even the best VPNs can’t guarantee your anonymity online. Your browsing behavior can still reveal your true identity in ways that your VPN service cannot control.

If you’re logged into a Google or Facebook account, a VPN won’t be able to stop those companies from monitoring your activity.

There’s also a collection of techniques that advertisers use to track you across the internet. These include:

  • Web trackers and cookies: Websites use trackers and cookies to tailor their service to your specific needs. They store details about you, such as your name and geographic location, and can be used to identify you despite a VPN connection.

  • Browser fingerprinting: Most browsers reveal small pieces of information that are unique to you and your session. Authorities and advertisers can collate this information to build a ‘fingerprint’ that identifies your online presence, even when you’re using a VPN. You can learn more about browser fingerprinting in our best private browsers guide.

To maximize your anonymity, you should pair your VPN with a genuinely private browser like the Mozilla Firefox. You should also consider using an anonymous search engine like DuckDuckGo, and think carefully about your behavioral patterns online.

2. Your Privacy Depends On Your VPN Service

One of the key reasons to use a VPN is to stop unwanted individuals from observing what you do online. Just as you wouldn’t let a stranger watch you from the window of your house, you don’t want strangers watching you online.

However, by protecting yourself with a VPN, you’re still handing your browsing activity over to one unknown individual: your VPN service.

All of your traffic is routed through the VPN provider’s servers – meaning that, if it wanted to, it could see who you are and what you’re doing online. That’s why it’s crucial to look at the VPN’s logging policy before you start using it.

Your privacy is entirely dependent on how trustworthy the VPN service is. You need a VPN that will not log any personally identifiable information about you or your activities. Ideally, it will also have had its logging policy independently verified with a third-party audit.

Without a no-logs policy, a VPN is a threat to your privacy and is probably unsafe to use. To learn more about logging and for a list of genuine zero-logs VPNs, read our complete introduction to VPN logs.

3. It’s Illegal to Use a VPN in Some Countries

VPN apps are legal in most countries around the world, but there are still a small number of places where using a VPN is either illegal or restricted.

The countries that ban or regulate VPN use are:

  • Belarus
  • China
  • Iran
  • Iraq
  • North Korea
  • Oman
  • Russia
  • Turkey
  • Turkmenistan
  • United Arab Emirates

You could therefore be breaking the law by simply using a VPN, and you may be prosecuted if caught.

In China, for instance, anyone found using a VPN service that has not been explicitly approved by the government can be fined up to 15,000 yuan (equal to around $2,300).

NOTE: Using a VPN to perform illegal activities is still illegal, regardless of where you are in the world.

4. Good VPN Services Cost Money

The unfortunate truth is that a high-performing, safe VPN will cost you money.

It doesn’t have to break the bank, though. The average price of our top 20 recommended VPNs is just under $4 a month, with the cheapest option priced at $1.11/month. For a full price comparison, you can check out our recent analysis of how much VPNs cost.

While the best VPNs don’t necessarily cost the most money, you’re unlikely to find a service that’ll do everything you want for free. Free VPNs are available, but the overwhelming majority of them are either poor quality or genuinely dangerous to use. When it comes to your privacy and security, it’s just not worth taking the risk.

That said, we have come across a small handful of free VPN apps that can be trusted. These services are excellent, given that you’re not paying a cent, but their performance is limited. For example, most of them cap how much data you can consume each month.

5. Using a VPN Slows Down Your Connection Speeds

Using a VPN service will almost always slow down your connection speed. This is because, once you turn the VPN on, your connection starts to take a longer route to the internet, via your chosen VPN server.

With good-quality VPNs, the speed loss is minimal, to the extent that you won’t even notice it. For instance, Hotspot Shield delivers a speed loss of just 0.41%.

However, poor-quality VPNs can slow download speeds and increase latency to an unusable degree. This can be a major issue if your internet connection is already quite slow or if you’re doing something speed-sensitive, such as streaming, gaming, or torrenting.

EXPERT TIP: Very occasionally, a VPN will actually improve the speeds of certain activities by helping you to overcome ISP bandwidth throttling

6. VPNs Increase Data Consumption

By encrypting your data and hiding your traffic from unwanted surveillance, a VPN also increases the amount of bandwidth you use.

For mobile VPN users, this means that whenever you use your VPN while connected to cellular data and not WiFi, you’re consuming data at a faster rate than you would without the VPN turned on.

Our research has shown that VPNs increase data usage by anywhere between 4% and 20%, depending on which VPN protocol you’re using.

As a consequence, you’ll probably reach your contract’s monthly data limit much faster. If you’re abroad, you could end up paying more in data roaming charges than you would otherwise.

7. Some Online Services Ban VPN Users

Many online services discourage the use of VPNs or even prohibit them outright. This is often the case with streaming services like Netflix and BBC iPlayer, which try to block VPNs in order to stop you from accessing videos and movies that aren’t licensed in your geographic region.

Some online stores, such as Steam, also try to prevent users from accessing its service with a VPN. This is because it has localized versions of the store with region-specific prices and release dates.

Although it’s not illegal to use a VPN to unlock ‘hidden’ content on these sites (in most countries), it is clearly against the company’s terms of use. They have the right to suspend or delete your account if you’re discovered using a VPN.

NOTE: Our experts have reviewed over 68 VPN services and tested every one with Netflix. This includes poor-quality VPN services that are easily identified by Netflix’s censors. Despite this, we have never received an account suspension.

8. VPNs Don’t Protect You from Malware or Phishing Attacks

Misunderstanding the limits of a VPN can lead to the false impression that you are untouchable online.

While good VPNs provide essential protection from eavesdropping and man-in-the-middle attacks, they’re not a catch-all solution.

Using a VPN will not protect you against:

  1. Malware: A VPN will not secure your device against most forms of malware (such as viruses, spyware, and ransomware). It will prevent the injection of malicious code during a man-in-the-middle attack, though.

  2. Phishing Attacks: You’re still susceptible to social engineering attacks, like phishing scams, when you have a VPN on. Be careful about which links you click on and what you download to your device.

NOTE: Some VPN services do offer additional security features. NordVPN’s CyberSec feature, for example, includes an adblocker, anti-malware software, and a tool to prevent DDoS attacks. You’ll usually have to pay extra for these features, and they may not perform as well as equivalent standalone products.

9. It Isn’t Always Possible to Bypass Restrictions

More than a fifth of VPN users in the US and UK use their VPN to “access geographically restricted entertainment content,” according to our recent global statistics survey. This involves unblocking foreign streaming libraries and watching content that isn’t typically available in your location.

Other people use VPNs to access the free, global internet from inside high-censorship countries such as China, Turkey, and Iran.

Unfortunately, no VPN provider can guarantee that you’ll be able to bypass these restrictions at all times. Some VPNs are better than others, but even the best services get blocked from time to time. It’s essentially a game of cat-and-mouse between the streaming service (e.g. Netflix) or censorship system (e.g. Great Firewall of China) and your VPN provider.

Check out our best VPN lists for a regularly-updated overview of which VPN services are currently working to bypass specific restrictions.

10. Most VPNs Are Dangerous to Use

Your VPN provider has access to a lot of personal information. It can see your IP address, the websites you visit, and what you do on those websites.

Trustworthy VPN companies ignore this information, and most make sure it is never recorded in the first place.

However, while safe VPN companies make their money through your subscription payments, a large number of free VPNs are not safe. The companies behind these apps make money by collecting your personal information and selling it to the highest bidder.

In short: you are the product, not the VPN. For many of these companies, the whole purpose of operating a VPN service is to gather data to sell on for profit. This is the reason they’re often able to offer their VPN for ‘free’.

For this reason, using a VPN can often be more dangerous than not using a VPN. That’s why it’s crucial to do your research before downloading. Use a trusted, safe VPN, or don’t use one at all.

The Bottom Line

Using a VPN is undoubtedly crucial if you care about your privacy, security and freedom online.

A good one will hide your identity and keep your online activity hidden from the prying eyes of governments, ISPs, large corporations, network administrators, and hackers. It’ll also let you bypass geographical restrictions and access content that is blocked or censored in your location.

But a VPN won’t solve all your privacy and security needs. It’ll also slow down your connection speeds, increase your data usage, and a poor-quality VPN could leave you worse off than if you weren’t using one at all.
