Room For Improvement

Forescout Platform needs better integration, AI, cost-effectiveness, support, iOS compatibility, reporting, visualization, and seamless connectivity with third-party tools.
Illumio needs improved support, integration, OS compatibility, data security, detailed logs, interactive sessions, and tagging automation guidance.
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.
There could also be more examples of how the automations can be done using Illumio.
That's why I'm looking for comparisons with other products.
There should be an option to upgrade from the console to the latest version instead of performing manual upgrades.
 

Setup Cost

Forescout Platform offers flexible, endpoint-based licensing for medium to large organizations, though setup costs and complexity can be high.
Illumio offers flexible pricing based on workloads, with mixed views on cost, subscribing every three years.
Installing a physical box on each site can be expensive.
The overall pricing of Forescout Platform is reasonable for the functionality it provides.
I know that Illumio is the cheapest solution in the security area.
I think it's not very expensive if we compare it with Guardicore.
 

Valuable Features

Forescout Platform offers agentless deployment for enhanced device visibility, integration flexibility, and customizable network security and management solutions.
Illumio enhances security and usability with its Application Dependency Map, traffic analysis, and centralized policy management, aiding visibility and micro-segmentation.
The platform enables automated policy enforcement, allowing us to simulate and test policies before enforcement, streamlining our security operations.
The most effective feature has been network access management, which has been crucial for our primary use cases in the organization.
Illumio helps in audit purposes by saving data and showing blocked traffic, ensuring no outside traffic is allowed.
The most important feature is the traffic review analysis, where we use the draft view and the reported view that helps us understand how the application interacts with other applications in the environment, and based on that, we are able to define the policies.
The dependency map is the most valuable aspect.

Featured Reviews

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.
Alark Singh - PeerSpot reviewer
Visual traffic interface aids in network micro-segmentation while a streamlined update option enhances process efficiency
The strongest aspect of Illumio is the visual traffic interface, which allows us to see all traffic that communicates with our servers and allied companies. We can write rules that can be embedded into the IP table, making it easy to handle. Illumio enables us to see network flows, traffic sources, and destinations. The policy generation and enforcement capabilities are valuable, allowing for selective enforcement. Illumio helps in audit purposes by saving data and showing blocked traffic, ensuring no outside traffic is allowed.
