12 Disadvantages of VPNs You Should Be Aware Of

A VPN, or virtual private network, is often touted as an essential tool for protecting your privacy and security online. By encrypting your internet traffic and masking your true IP address, a VPN can help shield your online activities from snooping by your ISP, advertisers, or other third parties.

However, VPNs are not a magic bullet for privacy and anonymity. In fact, there are several significant potential disadvantages of VPNs that you should carefully consider before deciding to use one. A VPN may slow down your internet connection, limit what content you can access, and even lull you into a false sense of total security.

Here are 12 of the biggest potential downsides of using a VPN that you need to be aware of:

1. VPNs don‘t make you completely anonymous

One of the most common misconceptions about VPNs is that they make you completely anonymous online. While a VPN does mask your true IP address, your traffic can still be linked back to you in other ways – especially if you log into online accounts or services.

Your VPN provider can also see your real IP address and link your online activities to you if they keep logs. That‘s why it‘s critical to only use a trustworthy no-log VPN service. But even then, you are trusting your sensitive data to a third party.

Additionally, websites you visit can still track you in other ways besides IP address, like browser fingerprinting. Using privacy tools in addition to a VPN, like a private browser, is important for robust anonymity.

2. Not all VPNs adequately protect your privacy

The VPN industry is full of bold claims about privacy and security. But the reality is that many VPN services – especially free ones – do not actually use adequate encryption or security best practices to fully protect your data.

Some VPNs keep logs of your online activity that could be accessed by law enforcement or hackers. Others don‘t prevent IP or DNS leaks that could expose your real location. And some VPN apps have even been found to contain malware.

Choosing a reputable, secure, no-log VPN service is essential. Be sure to research a VPN‘s security standards, privacy policy, and company history before trusting them with your data. Avoid most free VPNs, which often have questionable security and privacy practices.

3. VPNs can slow down your internet speed

Using a VPN usually results in slower internet speeds compared to your normal direct connection. This is because a VPN must encrypt and decrypt your data as well as route your traffic through VPN servers, which takes extra time.

How much a VPN slows you down varies based on factors like your base internet speed, distance to the VPN server, and VPN server bandwidth. Premium VPNs typically have less speed loss. But in general, expect some slowdown when a VPN is active.

If you frequently engage in speed-intensive activities like streaming HD video or online gaming, the slowdown from a VPN may be disruptive. Test out a VPN during a trial period if you‘re concerned about the performance impact.

4. Many streaming services block VPNs

Speaking of streaming, many popular streaming platforms like Netflix, Hulu and BBC iPlayer try to block VPN users from accessing their content. This is due to geographic content licensing restrictions that require them to limit viewership to certain countries.

If you connect to a VPN specifically to unblock geo-restricted streaming content, you may be disappointed to find that many VPNs no longer work for this purpose. Streaming platforms have gotten better at detecting and blocking VPN IP addresses.

There are still some VPNs that work for accessing region-locked content libraries. But don‘t expect this to work consistently or forever, as the streaming services are constantly working on blocking unauthorizated cross-border access via VPN.

5. Some websites block VPNs due to spam & fraud

It‘s not just streaming sites that may restrict access to VPN users. Some other web services like online banking, e-commerce, or social media platforms may also block IP addresses associated with VPN servers.

This is often done to combat spam, fraud and abuse. Unfortunately, VPN users can get caught up in these IP bans, even if they are using a VPN for legitimate reasons. Having your connection blocked unexpectedly can be highly disruptive.

Getting blocked due to using a VPN can usually be resolved by switching to a different VPN server. But some websites have stricter blanket bans on all VPN connections that are harder to circumvent without turning off your VPN.

6. VPNs can be blocked entirely in restrictive countries

In some countries with restricted internet freedom, VPN usage is heavily regulated or banned entirely. Countries like China, Russia, Iran and others see VPNs as a tool for circumventing government censorship and restrictions.

If you are traveling to or living in one of these countries, using an unauthorized VPN service may be difficult or even illegal. The government may block access to major VPN services as well as sites where you can download VPN apps.

While there are some VPNs that still work in heavily restrictive countries, the options are much more limited. Be aware of the local laws and potential risks before deciding to use a VPN in a country known for internet surveillance and censorship.

7. VPNs use extra data for encryption

Because a VPN has to encrypt your traffic, it actually consumes more data than browsing without a VPN. Exactly how much extra data depends on factors like the specific VPN protocol and strength of encryption used.

For most people, this extra data usage is negligible. But if you have a limited mobile data plan, for example, the data usage from a VPN could potentially push you over your limit – especially if you use a VPN frequently for high-bandwidth activities like HD streaming.

If your internet service has strict data caps, be mindful of how often you keep your VPN connected. Consider using split tunneling, a feature of some VPNs that lets you route some traffic outside the encrypted VPN tunnel to conserve data and boost speeds.

8. Many free VPNs come with risks

Free VPNs can be very appealing for anyone looking to save money while still staying secure online. But the vast majority of free VPN services come with major risks and limitations that make them unsuitable for privacy-conscious users.

Many free VPNs support their business by logging user activity to sell to third-party advertisers. So they may actually undermine your privacy rather than protect it. Free VPNs are also more likely to have weak encryption, data leaks, and even malware.

Other downsides of free VPNs include slow speeds, limited data allowances, few server locations, and annoying ads. For all these reasons, I strongly recommend choosing an affordable, reputable paid VPN service over using a free VPN.

9. Not all paid VPNs block ads & malware

A VPN encrypts your internet traffic, but it doesn‘t necessarily protect your device against other threats like malware, viruses, trackers and intrusive ads. Many people assume all VPNs block these threats by default, but that‘s not the case.

Only some premium VPNs offer additional features like ad blocking and malware protection on top of the core VPN connection. But this is not a given. Other VPNs expect you to use separate antivirus and ad-blocking software for complete protection.

Before choosing a VPN, check the feature list to see if it includes malware protection or ad blocking if those are important to you. For maximum security, I recommend using a VPN together with a trusted malware and virus scanner.

10. A VPN doesn‘t prevent user error

At the end of the day, a VPN is just a tool. It can help improve your digital privacy and security, but it‘s not foolproof. No matter how secure your VPN is, it can‘t prevent you from making unwise decisions online.

If you use an insecure browser, visit shady websites, download suspicious files, or fall for phishing attempts, a VPN can‘t protect you. You still need to practice general internet safety and hygiene when using a VPN.

A VPN can lull some people into a false sense of total anonymity online, leading to reckless behavior. Remember, a VPN is part of a larger privacy & security toolkit – not a license to throw caution to the wind on the web.

11. Not suitable for all devices & platforms

While the best VPN services offer apps for all major devices and operating systems, some have more limited compatibility. Budget VPNs may only work on the core platforms like Windows, macOS, iOS and Android.

If you have smart home devices, gaming consoles, streaming boxes, or other IoT gadgets you want to protect with a VPN, your options may be more limited. Not all VPNs can be easily configured on these non-standard devices.

Some VPNs also don‘t work well in heavily sandboxed environments like Apple‘s iOS and iPadOS. Due to restrictions imposed by Apple, some VPN features and settings are limited on iPhone and iPad apps compared to desktop apps.

12. Good VPNs cost money

Perhaps the simplest disadvantage of VPNs is that a good VPN service costs money. Maintaining the robust server networks and security infrastructure needed to run a trustworthy VPN is expensive for the providers.

As discussed above, free VPNs are not recommended for most people due to major limitations and risks. Expect to pay at least a few dollars per month for a reputable VPN service, with the best ones costing around $10-15/month.

If you commit to a longer-term subscription of a year or more, you can often get significant discounts on the monthly price. But there‘s no avoiding the fact that a VPN is an ongoing subscription cost to factor into your budget.

The Bottom Line

While VPNs offer many privacy benefits, they are not perfect. VPNs can slow your internet speeds, get blocked by certain websites, and even put your privacy at risk if you don‘t choose a high-quality provider.

VPNs are also not compatible with every device and cost money for the most trusted services. What‘s more, even the best VPN can‘t make up for bad online security habits.

However, if you choose a reputable no-log VPN and use it as part of a larger toolkit of privacy tools and best practices, a VPN can be a very effective way to improve your digital privacy and security. Just be aware of the potential limitations and risks.

No privacy tool is perfect, and VPNs are no exception. But if you go in with realistic expectations, using a VPN can be a great choice to safeguard more of your online life from snooping and tracking.
