10 Common VPN Mistakes That Leave You Exposed
Even VPN users make critical errors that compromise their privacy. Learn the most common mistakes and how to avoid them.
Using a VPN is a great first step toward protecting your online privacy, but simply installing an app and pressing connect is not enough. Many people use VPNs incorrectly and end up with far less protection than they think. Here are the ten most common VPN mistakes — and how to fix them.
1. Using a Free VPN with No Premium Option
Not all free VPNs are created equal. There is a significant difference between a free tier offered by a reputable provider (like Proton VPN or Windscribe) and a VPN that is entirely free with no premium offering. Entirely free VPNs have to make money somehow, and the most common methods involve selling anonymised or not-so-anonymised user data, injecting advertisements into your browsing, or in extreme cases, using your device as part of a botnet.
Always choose a free tier from a provider that also offers paid plans. The free tier exists to attract customers who may upgrade, not to monetise your data.
2. Choosing a VPN Based in a Five Eyes Country
The jurisdiction of your VPN provider matters significantly. VPN companies based in the United States, United Kingdom, Canada, Australia, or New Zealand (the Five Eyes countries) are subject to local surveillance laws that may compel them to cooperate with intelligence agencies or hand over user data. Choose providers based in Switzerland, Iceland, Panama, or the British Virgin Islands for stronger legal protections.
3. Not Verifying the No-Logs Policy
Many VPN providers claim to have a no-logs policy, but marketing claims are not the same as independent verification. Look for providers whose no-logs policies have been independently audited by reputable security firms like Cure53, PricewaterhouseCoopers, or Deloitte. An audited policy means that actual systems were checked, not just marketing documents reviewed.
4. Forgetting to Enable the Kill Switch
A VPN kill switch is a critical safety feature that blocks all internet traffic if your VPN connection drops unexpectedly. Without it, a temporary disconnection — which happens more often than most people realise — can expose your real IP address and unencrypted traffic for several seconds or minutes. Enable the kill switch in your VPN settings and never browse without it.
5. Using the Wrong Protocol
Many VPN apps default to protocols that may not be optimal for your situation. For everyday use, WireGuard is generally the best choice: it is faster, uses less battery, and connects almost instantly. If you are in a country with censorship and need to bypass deep packet inspection, OpenVPN over TCP on port 443 is harder to detect. Check your VPN settings and select the appropriate protocol.
6. Trusting Your VPN Completely on Shared Devices
If you use a VPN on a shared family computer or a work laptop, remember that the VPN only protects your internet traffic — it does not protect your data from other users of the same device. Your employer may still be able to monitor your activity through endpoint software installed on a work device. Use a VPN on personal devices for personal browsing.
7. Forgetting About WebRTC Leaks
WebRTC is a browser technology used for video calls and real-time communication. It can reveal your real IP address even when you are connected to a VPN, through what is known as a WebRTC leak. To check for leaks, visit a leak-testing site while connected to your VPN. If your real IP is visible, you can disable WebRTC in your browser settings or use a browser extension to block it.
8. Using the Nearest Server by Default
Connecting to the server geographically closest to you is usually a good strategy, but not always. Some nearby servers may be overloaded with other users, resulting in slow speeds. Experiment with a few different servers in your region and compare speeds. Many VPN apps show server load percentages that can help you identify less congested options.
9. Not Using HTTPS in Addition to VPN
A VPN encrypts traffic between your device and the VPN server. But once traffic leaves the VPN server and travels to its destination, it is only protected if the destination uses HTTPS. Always look for the padlock icon in your browser’s address bar, particularly when entering any sensitive information like passwords or payment details.
10. Using a VPN Only Sometimes
Selective VPN use can create a false sense of security. If you use a VPN only when you remember, you will inevitably have unprotected sessions on public Wi-Fi or other insecure networks. Consider using your VPN permanently by setting it to connect automatically when you start your device or join a new network. Proton VPN’s unlimited free tier makes always-on use practical without any data cost.
Conclusion
Getting the most from a VPN requires more than just installing an app. By avoiding these common mistakes — verifying no-logs policies, enabling kill switches, choosing the right protocol, and checking for leaks — you can significantly increase the protection your VPN provides. Take fifteen minutes to review your VPN settings and make sure you are not accidentally undermining your own privacy.
