Staying Secure Online: Top 5 Most Common Mistakes When Using VPNs and How to Avoid Them
Virtual Private Networks (VPNs) have become essential tools for internet users seeking privacy, security, and unrestricted access to content. As of 2024, over 1.6 billion people worldwide use VPNs, according to Statista. Whether for personal privacy, secure banking, or bypassing regional restrictions on streaming services, the benefits of VPNs are clear. However, simply turning on a VPN isn't a guarantee of perfect security or anonymity. Many users, both beginners and seasoned tech enthusiasts, make critical errors that can compromise their privacy, slow down their internet, or even expose them to new risks.
This article dives deep into the top 5 most common mistakes when using VPNs and, more importantly, shows you how to avoid them. With the right knowledge, you can maximize your VPN's effectiveness and enjoy a truly safer online experience.

1. Relying on Free VPNs Without Understanding the Risks
It’s tempting to choose a free VPN—why pay for something you can get at no cost? However, this is one of the most widespread and dangerous mistakes. Free VPNs often come with significant trade-offs that can put your privacy and security at risk.
A 2023 study by CSIRO found that 38% of free VPN apps for Android contained malware, and 75% used third-party tracking libraries. Many free VPNs log your data, sell your browsing information to advertisers, or inject ads directly into your browsing sessions. Some even have weak or outdated encryption, meaning your online activity isn’t truly protected.
Here’s a comparison of typical features between free and reputable paid VPNs:
| Feature | Free VPNs | Paid VPNs |
|---|---|---|
| Encryption Strength | Often outdated/weak | Industry-standard (AES-256) |
| Data Logging | Commonly logs and sells data | No-logs policies, independently audited |
| Speed | Slow, throttled bandwidth | Fast, stable connections |
| Server Locations | Limited, often crowded | Thousands worldwide |
| Customer Support | Minimal or none | 24/7 live support |
How to avoid: Always research the VPN provider before installing. Look for transparent privacy policies, independent security audits, and reviews from reputable sources. If privacy and security matter to you, investing in a reputable paid VPN is worth it.
2. Neglecting to Use the Kill Switch Feature
A VPN’s kill switch is a crucial feature that halts your internet traffic if the VPN connection drops unexpectedly. Without a kill switch, your device can revert to your normal, unencrypted internet connection, inadvertently revealing your real IP address and online activity.
According to a 2022 survey by VPNMentor, only 42% of VPN users knew if their VPN offered a kill switch, and even fewer had it enabled. This oversight is especially risky when using public Wi-Fi networks or accessing sensitive information.
How to avoid: Always enable the kill switch in your VPN app’s settings. Most leading VPNs like ExpressVPN, NordVPN, and Surfshark offer this feature, but it may not be turned on by default. Double-check and test it by briefly disconnecting your VPN to ensure your internet traffic is blocked as expected.
3. Using Outdated VPN Apps and Protocols
VPN providers regularly update their applications and protocols to patch security vulnerabilities and improve performance. Using an outdated VPN version or an older protocol (like PPTP or L2TP) can leave you exposed to hackers or surveillance.
For example, PPTP (Point-to-Point Tunneling Protocol) was once popular but is now considered insecure. In 2023, Microsoft formally advised against using PPTP, citing well-known vulnerabilities. Modern VPNs use protocols like OpenVPN, WireGuard, or IKEv2/IPSec, which offer much stronger security and faster speeds.
How to avoid: Always keep your VPN app updated—turn on automatic updates if available. In your VPN settings, select a secure protocol (OpenVPN or WireGuard are highly recommended). Avoid using deprecated protocols unless you have a specific, low-risk use case.
4. Not Protecting All Devices or Using Split Tunneling Incorrectly
Many users only install VPNs on their laptops or desktop computers, forgetting about smartphones, tablets, or smart TVs. As of 2024, over 54% of global internet traffic comes from mobile devices (DataReportal). If these devices aren’t protected, your privacy is only partial.
Split tunneling, a feature offered by many VPNs, lets you choose which apps or traffic go through the VPN and which use your regular connection. If not configured carefully, split tunneling can inadvertently leak sensitive data outside the VPN tunnel.
How to avoid: Install your VPN on every device you use to access the internet—most subscriptions cover 5–10 devices simultaneously. If you use split tunneling, review the apps or websites excluded from the VPN and ensure no sensitive activity is left unprotected.
5. Failing to Check for DNS and IP Leaks
Even with a VPN connected, DNS and IP leaks can expose your real identity and location to websites and trackers. A 2023 study by Comparitech found that about 16% of VPN users experienced DNS leaks, often without realizing it.
DNS leaks occur when your device sends domain name requests outside the VPN tunnel, revealing your ISP and geographic location. Similarly, IP leaks can happen due to browser vulnerabilities (like WebRTC leaks) or misconfigured VPN software.
How to avoid: Regularly test your connection using online tools such as ipleak.net or dnsleaktest.com. If you detect leaks, check your VPN settings for DNS protection options, enable features like WebRTC blocking, or contact your provider’s support team.
Other Overlooked Mistakes with VPN Usage
While the five mistakes above are the most common, there are other pitfalls to be aware of:
- Using VPNs for illegal activity: VPNs are legal in most countries, but using them to break the law is not protected. - Ignoring jurisdiction: Some VPN providers are based in countries with invasive surveillance laws. Research the VPN’s headquarters and legal obligations. - Weak passwords: If your VPN account is protected by a weak or reused password, hackers could gain access to your account and settings.Small habits, like reviewing VPN app permissions and logging out from unused accounts, also contribute to safer VPN use.
Final Thoughts on VPN Mistakes and Best Practices
VPNs are powerful tools, but only when used correctly. Falling into common traps—like relying on free VPNs, neglecting updates, forgetting to enable critical features, or failing to protect all your devices—can undermine the very security and privacy you seek.
The good news? Avoiding these mistakes is straightforward: invest in a reputable VPN, turn on essential features like the kill switch, keep your apps updated, protect every device you use, and regularly check for leaks. By following these best practices, you can browse, stream, and work online with far greater confidence and safety.
