What is a VPN and why do you need it?
In brief: what is a VPN?
VPNs are becoming increasingly popular among internet users who value their privacy and want to safeguard their online activities from prying eyes. But what exactly is a VPN, why might you need one, and how do you choose the best option? Read on to find out.
What is a VPN?
A VPN, or Virtual Private Network, acts like an encrypted virtual tunnel. All your online activity is routed through this tunnel before reaching the internet. This ensures that everything passing through is encrypted and remains anonymous. Everyone has an IP address that, much like a home address, can be traced back to you. Thanks to the VPN—the virtual tunnel—your own IP address stays hidden, and your internet traffic appears to come from a different IP address that can't be traced back to you. It's best to protect both outgoing and incoming data. The latter is handled by a firewall. You might be wondering: What is a firewall? Simply put, while a VPN protects your outgoing data, a firewall filters incoming data.
How does a VPN work? A practical example
Imagine you're at an airport and connect to a public Wi-Fi network. Normally, your internet traffic—like accessing your banking app or logging into your email—would travel unsecured over that network, potentially visible to malicious actors. With a VPN, an encrypted 'tunnel' is first established between your device and the VPN server. All data you send is encrypted before being transmitted to the website or app via that server. As a result, the Wi-Fi administrator or a hacker only sees encrypted, unreadable data and the IP address of the VPN server—not your real location or information. This way, you stay safe and anonymous, even on the most insecure networks.
Why do you need a VPN?
1. Protecting your privacy
Without a VPN, your online behaviour is visible to websites, advertisers, and your internet service provider. With a VPN, your browsing habits remain private.
2. Accessing restricted content
A VPN allows you to connect to servers in other countries. For example, you can watch UK TV while abroad or stream American Netflix series that aren't available here.
3. Secure remote working
Working from home or on the go? A VPN lets you securely connect to your company's network, keeping sensitive data protected.
4. Extra protection against hackers
Especially on public Wi-Fi (like in hotels, airports, or cafés), you're vulnerable to cyberattacks. A VPN prevents hackers from snooping on your traffic.
How to choose the best VPN?
Not all VPNs are created equal. When selecting a VPN, consider the following factors:
- Security: Opt for strong encryption (like AES-256) and reliable protocols such as WireGuard or OpenVPN.
- No-log policy: Ensure the provider doesn't store any data about your traffic.
- Server locations: The more servers worldwide (and in the UK), the faster and more versatile the connection.
- Speed: Choose a VPN with proven fast servers, especially for streaming or video calls.
- Ease of use: An intuitive app and simple installation make a big difference.
- Value for money: Don't just go for the cheapest option, but look for the best balance between features and reliability.
Popular choices include NordVPN and Surfshark. They offer excellent privacy and high speeds.
