What is a VPN for?
A VPN (Virtual Private Network) ensures your online privacy by acting as a secure tunnel between you and the web, encrypting your internet data.
No matter how you’re connected, public or private Wi-Fi, 4G, or your location (home, public place, or office), a VPN makes you invisible.
Note: a VPN should not be confused with antivirus software. An antivirus protects your device, while A VPN encrypts your internet traffic to protect your online activity from prying eyes. Both tools are complementary to ensure full online safety.
How does a VPN work?
When you visit a website, many pieces of data are exchanged between your device and the server. A VPN isolates this data inside a secure tunnel.
As a result, the website you’re visiting cannot trace your real IP address, it only sees the VPN server’s information.
What are the benefits of a VPN?
The main benefit of using a VPN is protecting your online privacy at all times.
With the rise in online shopping, users often enter their bank details without proper protection, even beginner hackers can intercept this data.
A VPN is therefore essential for secure browsing and protecting sensitive personal information.
A VPN also allows you to connect to servers around the world, which can unlock price differences between countries. For example, during Black Friday, connecting to a US server may offer better deals than using a UK one. This trick also works for flight tickets and streaming subscriptions (like Netflix).
Some VPNs also offer Smart DNS features, letting you hide your IP and access geo-blocked content, perfect if you don’t fully trust your ISP.
How to choose a VPN?
Most VPN providers offer a free trial before you commit. While there are some free VPNs available, paid solutions are generally more reliable, more secure and offer better performance.
Key criteria to consider:
- Speed: Your VPN must remain fast, even when streaming or downloading
- Server Network: More servers = fewer users per server = smoother browsing
- Encryption: Look for AES-256, the gold standard for online data encryption
- Privacy Policy: Always review how your data is logged or handled
How to connect to a VPN?
Though VPNs are complex tools, using them is simple and doesn’t require advanced technical skills.
- Download the software: Download it from the provider’s website (for desktop) or from the App Store / Google Play (for mobile/tablet)
- Log in: Enter your credentials when launching the app. Some providers like ExpressVPN may require an additional access code for security
- Choose your server: Pick from a list of countries/servers. A few clicks are all it takes to connect securely
