Benefits of VPNs: Privacy, Safer Public WiFi and Realistic Everyday Use Cases

TechnologyUpdated 2026-05-0910 min read

VPNs can add a privacy layer, protect traffic on public WiFi and hide your IP address from websites, but they are not complete anonymity tools.

Quick answer: A VPN is useful when you want an extra privacy layer, especially on public WiFi. It can hide your IP address from websites, but it does not make unsafe behaviour safe or turn you into a digital ghost.
Security note: This guide is educational. Always follow your organisation's security policies, keep recovery details safe and use trusted providers for sensitive accounts or data.

Key benefits

  • Adds protection on untrusted WiFi.
  • Can hide your IP address from websites and services.
  • May reduce some tracking by network operators.
  • Useful for remote work policies in some organisations.
  • Encourages people to think more carefully about privacy.

What a VPN does

A VPN creates an encrypted tunnel between your device and the VPN provider. This can protect traffic from local network snooping, such as on public WiFi, and changes what IP address websites see.

What a VPN does not do

A VPN does not stop phishing, malware, weak passwords, tracking inside logged-in accounts or you willingly handing data to a dubious site called definitely-not-a-scam.example. Sorry, the cloak is not that magic.

Choosing a VPN sensibly

Look for clear privacy policies, good reputation, transparent pricing and apps for your devices. Free VPNs may come with trade-offs around speed, advertising or data practices.

Better privacy stack

A VPN works best alongside password managers, two-factor authentication, browser privacy settings, software updates and sensible phishing awareness.
