A Wi-Fi network is convenient, but it's also an invisible door. Poorly secured or badly configured, it gives everyone within range access to your internal network.
And public Wi-Fi networks — in cafés, airports, hotels — are a classic hunting ground for intercepting data.
The risks
Old encryption protocols, shared passwords, no separation between guest and internal networks — all of this turns Wi-Fi into a weak link.
Within range— anyone who picks up your signal is a potential attacker if the network is poorly secured.
How to secure Wi-Fi
- Modern encryption (WPA3) and a strong password
- A separate guest network, isolated from the internal one
- Hiding or restricting administrative access
- A VPN when using public networks
- Regular password changes and audits of connected devices
How to protect yourself
A few measures make a big difference to Wi-Fi security. For employees the rule is simple: on a public network — always through a VPN.
