Comparison Buyer's Guide

Executive Summary

Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
6.4
Aruba ClearPass offers ROI through data security and management ease, but licensing and price concerns may cause confusion.
Sentiment score
6.7
Forescout Platform is valued for enhancing security, automating remediation, saving costs, and improving network reliability and privacy.
Sentiment score
7.3
Portnox CORE improved network visibility, security, and efficiency, reducing costs and enhancing decision-making through detailed analytics and automated features.
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.
If you were moving from a traditional on-premise NAC that was 100% managed by the IT department, there would be great savings in going to a cloud-based NAC with Portnox.
 

Customer Service

Sentiment score
6.7
Aruba ClearPass customer support is praised for expertise and efficiency, despite occasional slow responses and communication issues.
Sentiment score
6.7
Forescout Platform's customer service is responsive and helpful, but varies in response time, knowledge, and consistency.
Sentiment score
7.3
Portnox customer service is highly rated for responsiveness and efficiency, with room for improvement in local services and communication.
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.
We have escalated questions to tech support, and I would rate the technical support an eight out of ten.
They respond very immediately and provide detailed, amazing support.
I was seeing weird things, and they were able to explain things to me and help me quickly find a resolution.
They resolved issues quickly and provided clear explanations.
 

Scalability Issues

Sentiment score
8.2
Aruba ClearPass is praised for scalability and integration, though some find its initial setup complex despite flexible licensing.
Sentiment score
7.7
Forescout Platform scales efficiently with seamless appliance additions, despite potential cost concerns, proving reliable in large deployments.
Sentiment score
7.5
Portnox is scalable and flexible, supporting growth efficiently, though larger setups may require more resources, rated seven to ten.
I believe the scalability of ClearPass is rated as ten out of ten.
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.
Aruba ClearPass is very scalable.
Scalability can be costly since a physical box needs to be installed for every site.
 

Stability Issues

Sentiment score
8.2
Aruba ClearPass is stable and reliable, effectively handling high loads with high user ratings despite minor integration issues.
Sentiment score
8.0
Forescout Platform is praised for its stability and reliability, with minor issues that do not overshadow its performance.
Sentiment score
7.6
Portnox offers reliable uptime, though CORE users report issues with vendor support and configuration, while Clear performs smoothly.
There are issues with some versions, especially in integrating with AD and SSL configurations over port sixty-three.
There aren't many stability issues, but sometimes the guest management function occasionally throws errors.
I would rate its stability as 9.5 out of ten.
The product itself is available and its uptime is 100%.
In the four years that I used Portnox, if it crashed or the server crashed, that would not have been more than once.
 

Room For Improvement

Aruba ClearPass needs better UI, APIs, documentation, third-party compatibility, independent integration, cost effectiveness, and intuitive setup.
Forescout Platform struggles with usability, integration, false positives, high costs, needing improved analytics, support, scalability, and simplified licensing.
Portnox can improve with better GUI, integration, scalability, support, licensing, false positives, documentation, and Wi-Fi and AI analytics.
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 console is a fat client, and a web interface would be preferable.
Ideally, we should be able to search for any MAC address in the database, regardless of its authentication status, to see all its associated groups and potential conflicts.
When I'm doing filtering at times, it doesn't filter the items properly.
They don't have much support during Asia Pacific hours.
 

Setup Cost

Aruba ClearPass is seen as costly but competitive, with complex licensing and valuable long-term affordability for larger enterprises.
Forescout Platform is costly but offers flexible licensing and comprehensive features, competing well with Cisco ISE.
Portnox offers scalable, competitive pricing based on ports, with annual fees, appreciated value, but no perpetual license option.
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.
Installing a physical box on each site can be expensive.
If you compare Portnox with all other well-known standard products, it is the cheapest.
The pricing is a bit high, possibly due to the cloud features and running instances across regions like the US, Asia, and Europe.
It is a bit on the high side, but considering the cloud features and how much it costs to run the instance in the cloud, it is not unreasonable.
 

Valuable Features

Aruba ClearPass provides comprehensive network security through advanced policy management, seamless integration, robust authentication, and user-friendly centralized management.
Forescout Platform offers excellent device visibility, network control, and integration, praised for agentless operation, flexibility, and real-time alerts.
Portnox provides scalable, agentless network visibility with intuitive dashboards and automated security integration, enhancing efficiency and endpoint compliance.
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.
Aruba ClearPass is a very user-friendly solution compared to Cisco ISE.
One of the most valuable features of Forescout Platform is its automation, particularly the ability to automate remediation of rogue devices on the network.
It's notable how Portnox has improved operational efficiency.
It is very easy to implement on our current network hardware.
We use Meraki for our switching, making it simple to point all our networks and offices to Portnox.

Odai Halawani - PeerSpot reviewer
It's an easy and effective solution, especially for device profiling without agents
Forescout Platform's most valuable aspect is its excellent device profiling for devices without agents, which is crucial for our work due to challenges with agent-based devices. Its isolation and blocking actions are particularly effective for network security. The device compliance feature helps us ensure device compliance through immediate actions like updating antivirus software. We have already integrated Forescout with antivirus and vulnerability assessment tools, allowing it to monitor vulnerability scores and automatically isolate devices if critical vulnerabilities are detected.
Scott Kerr - PeerSpot reviewer
It is seamless and integrates well with our Azure setup
We use devices like PLCs and controllers, and when we receive a request to allow one on the network, we bypass typical authentication, associate it with a group account, and push it to a firewalled VLAN. However, problems arise when the same MAC address is requested for a different project. Our current system only finds authenticated MAC addresses, making it difficult to troubleshoot when the same device is used for multiple purposes. Ideally, we should be able to search for any MAC address in the database, regardless of its authentication status, to see all its associated groups and potential conflicts.
