Do You Need a VPN? Honest Basics

VPN marketing is everywhere, and it often overstates what a VPN actually does. Here's an honest look at when a VPN helps, when it doesn't, and whether you need one.

VPN adverts make bold claims about privacy, security, and invisibility online. The reality is more nuanced — a VPN is useful in specific situations, but it's not the blanket security solution that marketing often implies.

What a VPN Actually Does

A VPN (Virtual Private Network) creates an encrypted tunnel between your device and a VPN server. This does two things:

  • Hides your traffic from your internet service provider (ISP) — they can see you connected to a VPN but not what you're doing.
  • Masks your IP address — websites you visit see the VPN server's IP address, not yours.

That's it. A VPN does not make you anonymous, does not protect you from viruses, and does not prevent phishing. It's one specific tool for one specific job.

When a VPN Is Genuinely Useful

  • Public Wi-Fi — coffee shops, airports, hotels. On an unknown network, a VPN prevents others on the same network from intercepting your traffic.
  • Privacy from your ISP — if you don't want your internet provider to see which sites you visit, a VPN helps with this.
  • Accessing content in another country — if you need to reach a service that's geographically restricted.
  • Working remotely — many employers require a VPN to connect securely to company systems.

When a VPN Doesn't Help Much

  • Protecting against viruses or malware — use Windows Security for that.
  • Preventing phishing — being aware of suspicious emails and links is what works here.
  • Making you "completely anonymous" — websites can still identify you in many ways even through a VPN.
  • Securing your accounts — use strong passwords and 2FA for that.

Free VPNs: Be Careful

Free VPN services have to pay for their servers somehow. Many do this by logging and selling your browsing data — the exact opposite of what you're trying to achieve. If you decide to use a VPN, look for one with a clear, independently audited no-logs policy. Well-regarded paid options include Mullvad and ProtonVPN (ProtonVPN also offers a free tier with no data logging).

A VPN is not essential for most home users. If you're on a trusted home network, keep Windows and your browser updated, use Windows Security, and practise safe browsing — you're already doing the most important things. A VPN is a useful extra, not a foundation.

Frequently asked questions

Does a VPN protect me from hackers?

Partly, in limited circumstances. On public Wi-Fi, a VPN prevents others on the same network from intercepting your data — that's a real protection. But at home, on your own secured Wi-Fi network, a VPN adds very little protection against hacking. Most attacks come via phishing emails, malicious downloads, and weak passwords — none of which a VPN addresses.

Will a VPN slow down my internet?

Usually a little, yes. Your traffic is being routed through an extra server and encrypted, which adds a small overhead. With a good paid VPN service and a fast internet connection, the slowdown is often barely noticeable for everyday browsing. Streaming and gaming are more sensitive to latency, so results vary. Free VPNs tend to be slower due to overloaded servers.
