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.

Centralized analytics have strengthened patch visibility and support efficient regulatory reporting
From my experience, I assess the product's analytics capabilities as successful. It helped us significantly with patching and managing the risk of the patching process across all our environments, including network devices with Windows and Unix systems. The product covered several environments and gave us exactly what we needed in our environment. Tenable Security Center's centralized platform helped with risk assessment and management across our IT environments. It covered the patching process, and we previously faced many issues regarding how to patch different environments, how to monitor the patching process, and whether it was successful or not. We obtained good reports showing when patches were closed and the details of each patch, including who executed it and everything related to the patching process until it was closed. This gave us good details about the process which helped us significantly in our reporting and even in audits, whether internal or external. We learned how to close audit issues safely and successfully. We used the dashboards for real-time threat insights and extracted several dashboards from Tenable Security Center. We use these dashboards in our cybersecurity dashboard and committees that we have. These dashboards are part of our committees, especially the cybersecurity committee and other committees that we attend.
