Forescout Platform's customer service is praised for responsiveness, but technical support experiences vary, with some delays and challenges noted.
I rate the technical support as one out of ten.

We have had experience with their technical support and must pay additionally for maintenance, support, and regional service.

Sentiment score
7.7
Forescout Platform is known for scalable expansion suitable for medium to enterprise entities, despite cost and setup complexities.
Factors like architecture, business nature, and legal limitations such as GDPR affect it.
Scalability can be costly since a physical box needs to be installed for every site.
 

Stability Issues

Sentiment score
7.7
Cisco ISE is highly reliable and stable, though larger deployments may experience occasional performance and configuration challenges.
Sentiment score
8.0
Forescout Platform is stable and reliable, though some users note performance issues; support enhances overall dependability and satisfaction.
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.
I would rate its stability as 9.5 out of ten.
 

Room For Improvement

Cisco Identity Services Engine requires improved integration, user interface, documentation, compatibility, and management efficiency to enhance user experience.
Forescout Platform needs better integration, AI, cost-effectiveness, support, iOS compatibility, reporting, visualization, and seamless connectivity with third-party tools.
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.
Additionally, the product is vulnerable and has many bugs.
Forescout Platform could enhance its integration of AI to improve IoT and OT device security to better meet our needs.
The console is a fat client, and a web interface would be preferable.
 

Setup Cost

Cisco ISE offers three pricing tiers, with high costs and complex licensing, but provides extensive features and potential discounts.
Forescout Platform offers flexible, endpoint-based licensing for medium to large organizations, though setup costs and complexity can be high.
The license costs can range between $50,000 to $100,000 per year for enterprises.
Compared to other solutions like HPE ClearPass, Cisco is more costly, and the conversation suggests a possible forty percent price gap compared to competitors.
Making large organizational costs significant.
Installing a physical box on each site can be expensive.
The overall pricing of Forescout Platform is reasonable for the functionality it provides.

Featured Reviews

SunilkumarNaganuri - PeerSpot reviewer
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.
AmjadKhan1 - PeerSpot reviewer
Blocks users who don't follow the policies and enforces compliance
The solution has a compliance enforcement feature that sends non-compliant systems to quarantine. Forescout Platform is a good product that provides seamless integration with Cisco Juniper and other devices. We wanted Forescout Platform to integrate with our firewalls and some vulnerability patch management solutions. Forescout Platform is currently the best product and top-of-the-line NAC solution in the market. I always recommend this product to other companies as well. We have 365 subsidiary companies. I work in the head office, and I always recommend it. This solution will be purchased by other companies in the next financial year. Overall, I rate the solution ten out of ten.
