Stay Safe on Public Wi-Fi

Free public Wi-Fi is widely available in places like cafés, hotels, train stations, and on public transport. Although it’s convenient, it can also pose serious security risks—especially if you're accessing sensitive information.

A recent study by cybersecurity company NordVPN found:

  • 70% of UK commuters use at least one device during their journey.

  • 28% of UK commuters are using their travel time to do work related tasks.

  • 13% of UK commuters take no steps to protect their data on public Wi-Fi.

Fraudsters can easily create hot-spots which are designed to look like legitimate free wi-fi networks. If you connect to one of these in error, your data and device can become compromised.

If you’re accessing work systems or info on public Wi-Fi:

  • Make sure you are following your organisation’s policies and procedures. If in doubt, contact IT before connecting to an unknown network.
  • Check that your work device has an approved VPN installed and make sure you know how to activate it. If you're unsure, contact your IT team.
  • Avoid logging into confidential NHS systems or work platforms unless absolutely necessary. Consider whether it’s appropriate to access that information in a public setting where someone could see it.

If you’re using your personal devices:

  • Avoid sensitive transactions: don’t log into your online banking, personal email accounts, or health apps on public Wi-Fi unless you’re using a VPN.
  • Use a reputable VPN. Download a trusted VPN app from your phone or tablet’s official app store for added protection.

In all circumstances:

  • Add two-factor authentication to your accounts for extra protection.
  • Make sure you install the latest security updates for your devices.
  • Some devices automatically connect to any available Wi-Fi without asking permission. You can turn this feature off in the settings menu.
  • Use strong passwords: create unique, complex passwords or use a password manager.
  • Lock your device: use a password, PIN, or biometrics to protect your device
