The enterprise mode of WPA has always allowed you to give each user a unique username/password to login to the Wi-Fi or to utilize unique digital certificates for each user to install on devices for even more security. Now with WPA3-Enterprise, the security is increased as clients are now required to make sure it’s communicating with the real authentication server before sending login credentials. That verification was optional with the earlier two versions of WPA. There are also improvements to the encryption strength with WPA3-Enterprise. However, in most cases the enhancements are not a big enough difference to spend resources in upgrading all your hardware at once to support WPA3. So WPA2-Enterprise is still certainly a good secure choice these days.
