What Does VPN Mean?
First, let’s get through some basics that you should know: VPN stands for Virtual Private Network. Simply put, it’s a secure tunnel or connection between your device, phone, laptop, or tablet and the internet.
When you use a VPN, your online activity becomes hidden from hackers, your internet provider, or even government surveillance. This helps bypass the strict rules of some countries, access to different websites and games, and also, what’s most important, protects your data and internet performance.

What Does a VPN Do? Basic VPN Features You Should Know About
There are many different uses for a VPN, including:
- Encrypting your data: A VPN scrambles your internet traffic so that no one can read it. It uses advanced mathematical algorithms to convert your readable data into unreadable code before it leaves your device. Even if someone intercepts the data, all they see is gibberish, impossible to read without a special decryption key that is only your VPN server.
- Hides your IP address: It masks your real location by giving you a different IP address. An IP address is like your device’s home address. Websites and online services use it to know where you’re connecting from. VPN hides your IP address and keeps your real location private.
- Bypasses restrictions: With a VPN, you can access content that may be blocked in your country. Especially nowadays, VPNs have become very helpful for bypassing strict restrictions. Due to the VPNs, users can access different websites, tools, games, and enjoy internet freedom.
- Secures public Wi-Fi use: A VPN keeps your data safe on public networks, like cafes or airports. Public Wi-Fis is the most risky network. These are weekly protected, so they can be a good place for hackers and data theft. Using a VPN while connecting to public WI-Fis is highly recommended.
In short, a VPN keeps you private, secure, and free to explore the internet.

How Do VPN Servers Work?
If you want to clearly understand VPN’s working process, imagine this: every day when you connect to the internet from your devices without VPN, all your data and IP address goes directly from your machine to the website that you want to visit, so anyone on the network path can see what you’re doing.
With the help of a VPN, the process changes:
- You turn on the VPN app.
- Your data gets encrypted (turned into unreadable code so the hackers can’t read it without an encryption key).
- This encrypted data travels through a secure tunnel to a VPN server (which could be in another country).
- The VPN server forwards your request to the website.
- The website sees the VPN server’s IP address, not yours.
The VPN makes it nearly impossible for data thieves to track you.
VPN Safety: What You Should Know
You might ask, are VPNs safe to use? Generally speaking, yes, but only if you choose a reputable and trustworthy provider. A good VPN uses strong encryption, has a no-logs policy (meaning they don’t store your browsing data), and has been independently audited by third parties.
Free VPNs can be risky if they sell your data or annoy you with ads. So, make sure you choose a trustworthy VPN provider.
One of the best trusted VPN options is Proton VPN. Many users wonder if Proton VPN is legit, and the answer is yes. Proton VPN comes from the same people behind ProtonMail (a well-known encrypted email service).
Step by Step: How to Use a VPN
Using a VPN is easier than you might think. VPNs don’t require any special knowledge or technical expertise. They are intuitive and easy to use. Here’s a quick step-by-step:
- Choose a VPN provider: Look for trustworthy services. Some of the best VPNs for 2025 include Proton VPN, ExpressVPN, NordVPN, and Surfshark.
- Sign up and download the app: Most VPNs support Windows, Mac, Android, and iOS.
- Log in and connect: Open the app and choose a server. For example, pick a U.S. server to access American Netflix while abroad.
- Browse securely: If you did it all correctly, now your connection is private.

Setting Up a VPN
Most people just install the VPN app and hit “Connect.” But if you want to manually set up a VPN on your device:
- Go to your device’s network settings.
- Find the “VPN” or “Add VPN” feature.
- Enter the server address and your login details (it should be provided by your VPN provider).
- Save and connect.
Manual setup is more technical, so beginners usually use the app.
Turning Off the VPN
Sometimes you might want to pause your VPN, for instance, if a website doesn’t work properly with it. Here’s how to turn off the VPN:
- Open the VPN app or the extension on your PC.
- Tap “Disconnect” or toggle the VPN switch off.
- You can reconnect at any time.
Just remember: when the VPN is off, you lose the extra privacy layer.
How to Know: Is My VPN Working?
Here’s how to check if my VPN is working:
- Visit a site like whatismyipaddress.com.
- Compare your IP address before and after turning on the VPN.
- If the IP changes to the server’s location, it’s working!
Some high-quality VPNs often have a built-in “kill switch” to block internet traffic if the VPN connection drops unexpectedly. This provides more security in case of force majeure.
Free VPN: Is It Worth It?
People love free stuff, so what about a free VPN? There’s a catch: free VPNs often limit speed, data, or server choices. Some free VPNs also sell your data to third parties, which is so risky.
If you are looking for a free but at the same time secure VPN, a safe bet is Proton Free VPN, which is genuinely trustworthy, with no hidden tricks. It has limitations (fewer servers and slower speeds at peak times), but it is great for casual use, and if you like it, you can upgrade it at any time.

Nowadays, using a VPN is one of the smartest and easiest steps you can take to protect your internet life. Now you know what is a VPN, how VPN works, and how to pick the right one for you.
