Room For Improvement

Aruba ClearPass needs simplified licensing, UI, better integration, enhanced features, and improved support and documentation resources.

Network Engineer at a outsourcing company with 11-50 employees

Windows Server Administrator/ IT Support Officer at a financial services firm with 5,001-10,000 employees
It is possible to find the MAC address in the switch, but in Portnox, it is very useful to see the status of those ports, and that increases our security.

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.
AshishKumar Rai - PeerSpot reviewer
Security Consultant at a tech vendor with 10,001+ employees
Comprehensive visibility has strengthened endpoint control and automated threat response across networks
When it comes to improving Forescout Platform, I have faced some issues recently, particularly with the switch integration part. When integrating a switch, it asks for the vendor type, and often it does not match. For example, one series of HP switches may not be found in that vendor list. This leads to frustration because you have to check again with different HP models, and once you integrate a switch, you cannot edit the vendor list without removing it. Other issues are being worked on, particularly related to switch integration. I believe they will be fixed in the next upgrade or patch fix. There are no major issues, but the configuration changes needed for the switch model are necessary, and I think it would help if during integration, an admin user could check the password or credential used, as they currently cannot see the password after it is entered and saved.
Maurice Mwaura - PeerSpot reviewer
Product Manager at Applied Principles Limited
Unified access control has improved compliance visibility and simplified passwordless access
There is work to be done when it comes to making the solution more seamless. For example, when a user is denied access, they would need a way to maybe self-resolve themselves, perhaps a way to generate a ticket on their own, something around resolutions. When it comes to users using the product, that is where good products are differentiated from products that are a bit of a challenge. Portnox has much to do in terms of their reporting. The generated reports need improvement. Things that other tools would say are normal are usually not present. For example, there is a page called NAS devices or NAS network that is able to show the switches that have been managed. Currently, there is no way of generating an easy report or an easy way of just generating something to tell the customer what they have been able to achieve so far. This is not done yet and is still very manual. I think there is work to be done there. More integrations around the various products being used would be beneficial. So far I have not encountered any major challenge. Where there was a challenge, I think support came in and helped us resolve. In fact, most of the challenges are not with the product; they are with the customer environment. I think that is just to update their documentation where they have come across a new vendor for easier integrations in the future.
