Why public networks need care
Airports, hotels, cafés and shared workspaces may offer networks that are convenient but outside the user’s control. Attackers can create look-alike network names, and poorly configured local networks may expose connected devices to one another.
Modern HTTPS already protects many web connections, while a VPN can add a protected tunnel between the device and its VPN server.
Connect in the right order
Join the intended network, complete any legitimate captive portal, confirm normal internet access and then start the VPN client. If the portal will not open, temporarily pausing the VPN may be necessary, but reconnect it after portal access is complete.
- Confirm the network name with the venue
- Disable automatic joining for unknown hotspots
- Avoid sensitive actions before protection is active
- Keep file sharing and local discovery disabled when not needed
A VPN is not the only safeguard
Continue to use HTTPS, software updates and multi-factor authentication. Do not install certificates or device-management profiles requested by an unfamiliar hotspot.
If the network behaves unexpectedly, use a trusted mobile connection or leave the network rather than ignoring repeated security warnings.
