7 reasons to deploy Wi-Fi security in Enterprise mode

SMBs may find the Personal mode of Wi-Fi security easier to deploy, but that may be a costly mistake

Although it's tempting to use the Personal mode of Wi-Fi security, which is easy to setup and use, businesses and organizations really need to use the Enterprise mode of WPA2—also known as 802.11i. Although it requires a RADIUS server to do the 802.1X authentication and is more complex to setup, it provides superior Wi-Fi security and can save you time and money in the long run.

Here are several reasons why businesses and organization should utilize Enterprise-level Wi-Fi security.

1. Eliminates the security risks of shared passwords

When enabling the Personal mode—technically called the Pre-shared Key (PSK) method—of WPA or WPA2 security, you create one unique global password. Everyone enters this same password before connecting to the wireless network, which is then saved to the device. The problem here is that when a laptop or smartphone is lost or stolen, whoever gets their hands on it will have the password and can go to the location to connect to the network. Plus, when employees or staff leave the organization they still have the Wi-Fi password and access on any device they used to connect.

In order to properly protect your network you’d have to change the global Wi-Fi password every time someone loses a device or leaves the organization. This means informing everyone of the password change and entering the new password on every Wi-Fi device. Plus, with some Windows versions and other mobile devices, you have to delete or modify the existing saved password, since it will try to connect with the old one and not let you simply enter the new one when connecting. This may cause confusion with end users and thus more work for the IT staff to help them.
