Your data is encrypted
Anyone intercepting your connection sees scrambled data, not your passwords, messages or banking details.
Beginner guide
What is a VPN and do you need one?
A VPN encrypts your internet connection so nobody — not your ISP, not hackers on public Wi-Fi — can see what you do online. Here is everything you need to know.

The basics
What does a VPN do?
VPN stands for Virtual Private Network. When you turn on a VPN, it creates an encrypted tunnel between your device (phone, laptop, tablet) and a secure server. All your internet traffic passes through this tunnel.
This means:
Your ISP cannot see your activity
Your internet service provider knows you are online, but cannot see which websites you visit or what you download.
Public Wi-Fi becomes safe
Hotels, airports, cafés — the VPN protects you even on open networks where others can sniff traffic.
How it works
A VPN in 3 simple steps
1. You open the VPN app
Install the app on your phone or computer. Tap one button to connect.
2. Your traffic is encrypted
The VPN app encrypts everything your device sends and receives. It travels through a secure tunnel to the VPN server.
3. The server connects to the internet for you
The VPN server sends your requests to websites on your behalf. Websites see the server's IP address, not yours.
Who needs one
Do you need a VPN?
You use public Wi-Fi
If you ever connect to Wi-Fi in hotels, airports, cafés, coworking spaces or on public transport, a VPN is essential. Open networks are easy to intercept.
You value your privacy
Without a VPN, your ISP can see every website you visit. In some countries, ISPs can sell this data to advertisers. A VPN stops this.
You travel
When abroad, you depend on unfamiliar networks. A VPN keeps your connection secure wherever you are.
You work remotely
Protect business emails, files and logins from being intercepted, especially when working outside the office.
Choosing
What to look for in a VPN
No-logs policy
A good VPN does not store your browsing data. Look for providers whose policies have been independently audited.
Modern protocol
WireGuard-based protocols (like NordLynx) are fast and efficient. Avoid VPNs that only offer older, slower protocols.
Kill switch
If the VPN connection drops, a kill switch immediately cuts your internet so your real IP address is never exposed.
Multiple devices
You want to protect your phone, laptop and tablet on one subscription. Check how many simultaneous connections are allowed.

Free vs paid
Should you use a free VPN?
Most free VPNs are risky. They fund themselves by showing ads, selling your data to third parties, or limiting your speed and data so heavily that the VPN becomes unusable.
The one exception is Proton VPN, which offers a genuinely free plan with no data cap and no ads. The trade-off is that you are limited to 1 device and fewer server locations.
For full protection across all your devices, a paid VPN like NordVPN (from €2.99/month during Black Friday) is a better investment. The 30-day money-back guarantee means you can try it risk-free.
Common myths
VPN facts vs fiction
"VPNs are only for tech people"
Modern VPN apps are as simple as a messaging app. Install, tap Connect — done. No technical knowledge required.
"VPNs make your internet slow"
Older VPN protocols were slow. Modern ones like WireGuard add almost no noticeable delay.
"VPNs are illegal"
VPNs are legal in most countries, including the UK, France, Canada and the US. They are a standard privacy tool.
FAQ
What does VPN stand for?
VPN stands for Virtual Private Network. It creates an encrypted tunnel between your device and a server, so your internet traffic cannot be read by anyone in between.
Do I need a VPN at home?
A VPN at home prevents your ISP from monitoring your browsing activity. It is less critical than on public Wi-Fi, but still adds a layer of privacy.
Do I need a VPN on my phone?
Yes, especially if you connect to public Wi-Fi. Mobile VPN apps work in the background and encrypt all your phone's traffic automatically.
Are VPNs legal?
VPNs are legal in most countries, including the UK, France, Canada, the US and across the EU. A VPN is a privacy tool — using one is no different from using HTTPS.
Which VPN should a beginner choose?
We recommend NordVPN for beginners. The app is simple (one tap to connect), it covers 10 devices, and the 30-day money-back guarantee lets you try it risk-free.
