Aruba ClearPass is very scalable.
Factors like architecture, business nature, and legal limitations such as GDPR affect it.
The pricing model makes it challenging as the cost is substantial due to the per-node licensing model.

Room For Improvement

Aruba ClearPass needs user interface and integration enhancements, improved support, better scalability, simplified administration, and refined licensing models.
Cisco Identity Services Engine requires improved integration, user interface, documentation, compatibility, and management efficiency to enhance user experience.
Fortinet FortiNAC faces issues with integration, user interface, training, support, and network visibility, while being costly.
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.
Improvement in the interface design would make FortiNAC a better solution.
The graphical user interface (GUI) of Fortinet FortiNAC is very poor compared to competitors like Forcepoint and Cisco ISE.
 

Setup Cost

Aruba ClearPass is considered costly with complex licensing, but many find its value justifies the expense compared to alternatives.
Cisco ISE offers three pricing tiers, with high costs and complex licensing, but provides extensive features and potential discounts.
Fortinet FortiNAC offers competitive pricing with flexible licensing, good value, and affordability, especially in larger deployments.
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.

Enhanced device administration hindered by complex deployment and security limitations
Cisco Identity Services Engine (ISE) needs to improve the profiling preauthentication. They are very poor in asset classification and should focus on improving the preauthentication profiling, especially for NAC use cases. This will give them a roadmap for software-defined access (SDA) use cases and network segmentation. Threat detection capabilities are very weak. Additionally, the product is vulnerable and has many bugs.
Boaz Katabazi - PeerSpot reviewer
Seamless device discovery with integration and discovery capabilities
FortiNAC is very good in terms of device discovery and integration. I appreciate the feature where it can connect with different vendor equipment, regardless of the network devices from other vendors. That's something I appreciate about it, particularly in terms of adaptability. Despite the complexity of its interface, its discovery capabilities are commendable.
