Wi-Fi is one entry-point hackers can use to get into your network without setting foot inside your building. A small vulnerability in your Wi-Fi network can give a criminal access to almost all the devices that access that Wi-Fi. This could spell trouble for bank accounts, credit card details, child safety, and a whole lot of other concerns.
Your Wi-Fi should utilise a complex password. A VPN (virtual private network) can also make you more secure online. A VPN will encrypt all traffic leaving your computer until it arrives at its destination. If cyber criminals hack your connection, they won’t intercept anything but encrypted data.
