Room For Improvement

A more streamlined menu of licensing options would be helpful.

The whole setup works well with Cisco access points and Cisco switches, but when you have multiple vendors in the environment, such as HP switches or access points like Aruba, you'll find they will not work well with Cisco Identity Services Engine (ISE).
Technical Services Lead at Telenet Solutions
Pricing can be more expensive compared to other vendors, and there is a significant price gap observed, which doesn't seem justified by some specific features.
Solution Architect, Presales Engineer at a computer software company with 51-200 employees
They are very poor in asset classification and should focus on improving the preauthentication profiling, especially for NAC use cases.

Setup Cost

Aruba ClearPass's complex licensing can be costly, with better affordability than Cisco, necessitating careful initial licensing understanding.
Cisco ISE pricing is complex and costly, with strong vendor partnerships needed for discounts, favoring large enterprises over smaller businesses.

We cannot mix in prices, and of course, prices are going higher.
IT Network Operations Manager at KEDS
Aruba ClearPass is a premium product with higher pricing, which seems unnecessary given its complexity.

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.

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.
Mohamed Fouad - PeerSpot reviewer
Cybersecurity Team Leader at EMAK For Computer Manufacturing (ECM)
Network access control has centralized device profiling and automated user isolation
The best features Fortinet FortiNAC offers include great integration with other Fortinet products. We have most of the cybersecurity products from Fortinet, including FortiMail, FortiGate, and FortiManager, among many Fortinet products. The best feature is the integration with these products. Fortinet FortiNAC can also integrate with any switching vendor using SSH to manage switches. This integration capability is very beneficial. The integration with other Fortinet products and managing switches from different vendors has helped my workflow by providing automation that makes it easy to run actions. We execute and trigger actions through Fortinet FortiNAC on FortiGate. We set up trigger actions on FortiGate to be run through Fortinet FortiNAC directly. Whenever an action happens, it is triggered on Fortinet FortiNAC, allowing us to disable and isolate a user if that machine is infected. The automation and response functionality is powerful, and the integration is very good. Fortinet FortiNAC has positively impacted my organization by allowing us to control our network and save time. We manage multiple switches that allow many users, including guest users and corporate users. We have saved time and secured our resources while accomplishing a lot with Fortinet FortiNAC.
