Comparing VPN Security Across Different Platforms (Windows, macOS, Linux, Mobile) in 2025

In 2025, VPN is no longer be a need but an essential tool. It is one of the easiest and most effective ways to stay private and secure online. However, the level of VPN security also depends on the device and operating system you are using.

So, comparing VPN security across different platforms (Windows, macOS, Linux, and mobile) is more crucial than ever. In this guide, I will cover the key security strengths and weaknesses of each OS. Plus, I will provide tips to boost VPN security on any platform.

Why Does Comparing VPN Security Across Different Platforms Matter?

Not all VPNs work the same on every device. The security you get from a VPN depends a lot on the operating system. Here’s why you should know the key differences:

• Every platform has unique security risks. For example, Windows is a favorite target for hackers, and Linux is considered a safe option. 

• All devices have different built-in security tools. An extra layer of protection, like BitLocker on Windows and FileVault on macOS, interacts with VPNs differently.

• VPN protocol support is not universal. These gaps can affect how easily and securely you can set up your VPN.

• Some VPN providers offer advanced features like a kill switch or split tunneling only on certain devices.

Comparing VPN security across different platforms like Windows, macOS, Linux, and mobile can help you avoid the risks and cover the gap. To stay secure, your VPN setup should match the strengths and weaknesses of the device you are using.

How Secure Are VPNs on Different Platforms?

I have researched and tried major VPNs on different operating systems, and the level of security varies across all. Here’s a quick overview of how each platform handles it:

1. VPN Security on Windows

Windows supports the popular VPN protocols like OpenVPN, IKEv2, and WireGuard. You also get useful features like split tunneling and DNS settings in Windows 11 and 10. Built-in security tools, like Windows Defender, Secure Boot, and SmartScreen, also help in overall protection.

However, being the most used operating system makes it a key target for malware and cyberattacks. In the past, some VPN providers on Windows have shown security loopholes, especially in corporate setups.

Overall, it provides strong security when combined with good antivirus tools and user habits. Just keep in mind to be cautious about the VPN you use.

2. VPN Security on macOS

macOS is known for its solid built-in security tools like Gatekeeper, XProtect, and full-disk encryption. VPN clients work smoothly with the system and support secure protocols like WireGuard and IKEv2.

But in recent times, adware and tracking threats are increasing on Macs too. Plus, some VPN features like split tunneling came very recently. So, these new features are still functioning with limited capabilities.

3. VPN Security on Linux

Linux is still very popular due to its high security. Its open-source nature, strict user permissions, and support for advanced tools like SELinux and AppArmor offer high protection. 

However, the catch is that it is less user-friendly than other OS. VPN setup is still manual for many clients, and many distros skip features like secure booting or code signing.

Still, it is a great choice for tech-savvy users. So, if you know how to configure it properly, Linux can be the most secure option.

4. VPN Security on Mobile (Android and iOS)

Modern VPN providers on phones are fast, battery-friendly, user-friendly, and secure. Both iOS and Android offer sandboxing and privacy features like MAC address randomization. Android even supports advanced features like split tunneling, and iOS performs better when it comes to browser security.

But permission misuse, app-level data leaks, and background tracking can still occur, even with a VPN. Some free apps may also log your activity.

There are different kinds of gaps on different platforms. But VPNs can be very secure on any device, as long as you use a reliable provider, use a remote access VPN for the company’s network, keep your software updated, and follow good security habits.

A Quick Comparison of VPN Security Across Platforms 

To make things easy for you, here’s a simple comparison table of VPN security across platforms:

Platform	Popular Protocols	Strengthss	Weaknesses
Windows	OpenVPN, IKEv2, WIreGuard	Wide support from VPN apps, easy to use	More targeted by malware, needs regular updates
macOS	OpenVPN, IKEv2, WIreGuard	Built-in privacy tools	Some VPN apps lack advanced features on macOS
Linux	OpenVPN, WireGuard, IKEv2	Lightweight and highly secure for tech-savvy users	Manual setup, fewer user-friendly VPN options
Android	OpenVPN, WireGuard, IKEv2	Efficient on battery, supports modern protocols	App permissions vary, and free VPN apps are not reliable
iOS	WireGuard, IKEv2, Lightway	Excellent privacy	Limited split tunneling, strict control over VPN apps

How to Improve VPN Security on Your Device?

Whether you are using a VPN on Android, iOS, Windows, macOS, or Linux, these simple steps can boost your online privacy and protect your data. Here are the best practices you need to follow:

1. Pick a Trusted VPN Provider

Look for a VPN known for its security and privacy. Select the one that uses strong encryption (like AES-256 or ChaCha20) and has a clear no-logs policy. I would advise you to avoid free VPNs, as they often collect your data.

2. Turn on Kill Switch and Leak Protection

A kill switch cuts your internet if the VPN connection drops. This helps in protecting your real IP. Also, make sure your VPN can block DNS, IPv6, and WebRTC leaks. If not, please turn those off manually in your device settings.

3. Use Strong Passwords and 2FA

It is crucial to protect your VPN account with a unique and strong password. Enable two-factor authentication for an extra layer of security. If you are using VPNs for work, you can also consider setting up device certificates for added protection.

4. Keep Everything Updated

Regularly update your VPN app, device OS, antivirus, and web browser. Security patches can fix known vulnerabilities that hackers can exploit.

5. Choose the Right VPN Settings

It is recommended that you stick to modern protocols like WireGuard or OpenVPN. Avoid outdated ones like PPTP or L2TP. Use advanced features like split tunneling wisely. 

6. Use Additional Security Tools

VPN is a great way to safeguard your data, but don’t rely on just a VPN. Use a good antivirus, firewall, and privacy tools like ad blockers or trackers.

7. Test Regularly and Stay Informed

Check your VPN occasionally for IP or DNS leaks. Make sure that you are continuously learning about new vulnerabilities, so that you can handle them effectively.

Furthermore, you should look for VPNs that offer features like multi-hop, rotating IPs, or RAM-only servers for extra privacy.

Final Thoughts

I guess you understand that using a reliable VPN is more important than ever to keep your online activity private. However, as discussed in this guide, you need to understand how VPNs work with the operating system of your device.

Every platform has its strengths and flaws, so it is important to compare VPN security across different platforms. Choosing the right VPN for your OS helps you stay secure and in control of your data.
