Darko Skurla - PeerSpot reviewer
Senior Enterprise Customer Solutions Specialist at a comms service provider with 1,001-5,000 employees
Role-based policies have simplified secure access control for all users and smart devices
I do not know about the functionality of Aruba ClearPass integration with a third party. If you ask me if there is support for Zebra and for different IoT devices, they have it. However, I do not know how to describe integration with other products. Aruba ClearPass can act as a RADIUS server and it can connect to the domain RADIUS server, for example. The biggest problem is when a customer does not know what they want with Aruba ClearPass. I can recommend Aruba ClearPass to other users because it is very stable. My review rating for this product is ten out of ten.
NF
Network and Technology Information Manager at Akkodis
Has improved authentication management and simplified visitor network access
The log capacity in Cisco Identity Services Engine (ISE) could be enhanced because today natively on the ISE can only have a look at the logs from the day before. You cannot search into the oldest logs; you have to use another tool for that. This can be blocking if you don't have any log consolidation solution. To do a search for an issue or something that happened two days ago, you cannot search directly in there. The capacity of Cisco Identity Services Engine (ISE) could be enhanced. Something between one week and one month for the log capacity would be nice.
