Aruba ClearPass and Cisco Identity Services Engine (ISE) compete in network access control solutions. Aruba ClearPass has an advantage in third-party integration and support, while Cisco ISE is preferable for existing Cisco environments due to its seamless ecosystem integration.
Features: Aruba ClearPass offers a modular architecture, advanced 802.1x authentication, RADIUS server capabilities, and comprehensive API/third-party integration. It excels in BYOD onboarding with detailed visibility reporting. Cisco ISE provides centralized policy management with 802.1x authentication, extensive compatibility within the Cisco ecosystem, and it integrates well with Cisco’s broader security technologies, offering robust endpoint compliance and security management.
Room for Improvement: Aruba ClearPass could enhance its user interface, expand integration options, and offer more comprehensive setup tutorials. Customization support is also needed. Cisco ISE requires improvements in its licensing model, performance during upgrades, and easier navigation. Troubleshooting and visibility features need to meet user expectations better.
Ease of Deployment and Customer Service: Deployment of Aruba ClearPass can initially be complex but is easier to manage afterward. Cisco ISE may be challenging, particularly for users unfamiliar with Cisco systems. Both products offer responsive customer service, but Aruba is noted for superior international support.
Pricing and ROI: Both Aruba ClearPass and Cisco ISE have complex pricing structures, being premium solutions. ClearPass offers perpetual and subscription licenses, with costs justified by management ease. Cisco ISE, being mostly subscription-based, tends to be more expensive. Still, both provide significant ROI via secure network management, though Cisco ISE's high costs can be a concern given its complexity.
Using Aruba ClearPass has resulted in less engineering time compared to other products we've used.
The investment is huge for enterprise clients, but Aruba ClearPass makes processes easier.
Direct comparisons with Forescout reveal up to 30% to 40% difference in cost savings.
Portnox is one level up, as their customer support is outstanding.
We have faced delays in the resolution of production issues after raising tickets, which impacts productivity.
If Aruba ClearPass is not working, then the organization is not working because this is the access control in the organization.
I rate the technical support as one out of ten.
Cisco support has pretty good teams for support and every time we had good answers and we could somehow solve the issues we had.
Sometimes it's challenging to identify which support team is responsible for certain issues, which is a significant concern.
I believe the scalability of ClearPass is rated as ten out of ten.
Everything will be handled when you add new users because all configurations are deployed from the beginning.
In our environment, ClearPass handles up to 100,000 users, which is better than some other NAC solutions like Fortinox that scale up to 25,000.
Factors like architecture, business nature, and legal limitations such as GDPR affect it.
However, you can have some latency issues depending on where your devices are.
I have experienced more than three years without zero downtime with Aruba ClearPass.
There are issues with some versions, especially in integrating with AD and SSL configurations over port sixty-three.
However, there are disadvantages when it is not on-premises, as every NAC suffers from it if it is not on-premises.
Cisco Identity Services Engine (ISE) is considered very reliable and stable.
The stability of Cisco Identity Services Engine (ISE) is poor for certain use cases, like authentication.
Sometimes when we have upgrades or failovers with Cisco Identity Services Engine (ISE), we had some minor issues.
The language and policy enforcement mechanisms are not clear, making it difficult to use the product effectively.
It is also better to improve threat intelligence for built-in threat detection and prevention.
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).
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.
They are very poor in asset classification and should focus on improving the preauthentication profiling, especially for NAC use cases.
Achieving the best price requires careful selection from a menu of licensing options.
We cannot mix in prices, and of course, prices are going higher.
Aruba ClearPass is a premium product with higher pricing, which seems unnecessary given its complexity.
Compared to other solutions like HPE ClearPass, Cisco is more costly, and the conversation suggests a possible forty percent price gap compared to competitors.
The license costs can range between $50,000 to $100,000 per year for enterprises.
Cloud solutions are expensive, while on-prem setups with shared environments are cheaper but not effective.
In Aruba ClearPass, you can have control of all authentication in the company.
The ClearPass solution has reduced the amount of engineering time compared to previous solutions, making it more efficient for our purposes.
The most effective feature for us is the OnGuard feature.
Cisco Identity Services Engine (ISE) offers authentication using RADIUS, enhancing network security by separating and segregating networks.
There is value because it helps us secure the network and prevents certain things from happening which could cause financial loss.
The adaptability of Cisco Identity Services Engine (ISE) policy enforcement can fit to the site we have depending on which kind of devices we have on site and then the needs for authentication, granting access and then assigning each device into its correct network for segmentation.
