If you use a VPN, are you using it all the time and for everything on your desktop or laptop?
You probably assume that more is always better, right? It is like Windows users thinking if they install two antivirus tools, they will be safer -- not knowing that running two such tools could bring a system to a halt and wreak general havoc.

In this case, more is not always better. Let me explain.
The big VPN choice: System-wide or just in the browser?
Once you have selected which VPN to use, you then need to ask yourself: Is it best to use it system-wide or only for your web browser? Let me break down the answer for you.
First and foremost, using a system-wide VPN is going to consume more resources (RAM and CPU cycles) than just using a web browser extension. If your system is aging or has just enough RAM to run the OS and a few apps, a system-wide VPN could cause problems with performance.

On top of that, you need to consider what apps you use that require the service of a VPN. If you only use a web browser, a system-wide VPN is overkill. Maybe the only other app you use is an email client. If that client encrypts your outgoing email, a VPN is not necessary. If your email client does not offer encryption, a system-wide VPN is a good idea.
The same thing holds true for anonymity, as most email clients do not include such options. If, on the other hand, you access your email via a web browser, the extension is all you need.
The choice here is simple:
If you only use a web browser, an extension is fine.
If you use other apps that could benefit from encryption and anonymity, go for the system-wide VPN.
When things break
Here is an issue with VPNs that many do not talk about. Some apps will not work properly when a system-wide VPN is in use.
Also:When you should use a VPN - and when you shouldn't
One issue that can cause problems between an app and a VPN is geographic limitations. You might have an app that can only function within your country. A system-wide VPN might trick the app into thinking you are located in a different country, which could prevent it from working properly (or working at all). I have seen this happen on my own desktop with apps like Signal.
I recommend the following:
Use a system-wide VPN when not using apps that are negatively affected.
Use a browser extension only when the only app you are using is a web browser.
If you find a must-use app does not function properly with your system-wide VPN, turn the VPN off and switch to a browser extension. When you are done using that app, switch back to the system-wide option.

Just remember this: A VPN browser extension only protects data transmitted from within your web browser. If you need more protection than that, the system-wide version should be your go-to.
What is important to consider when choosing a VPN?
The security and privacy policy. You should look for VPN providers with a clear "no-logs" policy (meaning they do not track your online activity), strong encryption protocols (like AES-256), and a jurisdiction that respects privacy (avoiding countries within the "14 Eyes" alliance -- agreements among fourteen countries to share surveillance intelligence). Read a VPN's privacy policy carefully!
How do you ensure my VPN is actually working?
Use a leak test: After connecting to your VPN, visit a website like "ipleak.net" or "dnsleaktest.com" to confirm that your real IP address and DNS server are hidden. If you see any of your original details, your VPN is leaking data and needs to be configured properly or replaced.
Should you use the same VPN server location every time?
While it is easiest, always using the same server weakens your anonymity. Different VPN locations can give you better speeds and access different content, but also make it harder to link your activities.
How often should you change a VPN password?
Treat your VPN account like any other sensitive account, which means you should change your password every few months, using a strong, unique password.
Is a free VPN just as good as a paid VPN?
Free VPNs often come with tradeoffs, such as slower speeds, data caps, and, more concerning, the potential logging of your data. Paid VPN services are generally more reliable and trustworthy.
Should you leave your VPN running 24/7?
Although running your VPN constantly provides maximum protection, it can impact your internet speed and battery life (on mobile devices and laptops). Enable it whenever you are using public Wi-Fi, accessing sensitive information, or when you need increased privacy. Turn it off when you need maximum speed for streaming or online gaming, unless those activities particularly benefit from location spoofing.
What is split tunneling, and why would you use it?
Split tunneling allows you to choose which apps use the VPN and which connect directly to the internet. This is useful for optimizing performance. You might use the VPN for browsing and email while allowing a streaming service to bypass the VPN for faster speed.
How do you keep VPN software updated?
Most VPN apps have an option for automatic updates, which you should definitely use so you always have the latest security patches and bug fixes.
What if your VPN connection drops unexpectedly?
Most good VPNs (such as NordVPN, Surfshark, CyberGhost, IPVanish, ProtonVPN, and AtlasVPN) have a "kill switch" feature that automatically blocks all internet traffic if the VPN connection drops, preventing your data from being exposed.
Does using a VPN make you anonymous online?
A VPN significantly improves your privacy, but it is not a perfect solution. Combine a VPN with other privacy tools, like a privacy-focused browser, ad blockers, and secure messaging apps for the best results.
