Portnox is better than other solutions that I tried before, at least with Cisco, because it has lots of features that are not included in Cisco, so it is the best for me.

The Wi-Fi integration could be done better from their end. If there is an improvement, it should be around having more functions on the integration with the Wi-Fi controller I used, which was a UniFi controller, also on-prem.
