Comprehensive asset visibility and OT operations support enhance risk mitigation
I use Armis for asset discovery and vulnerability assessments of the OT network Armis is easy to use. Very few software solutions have OT capabilities that do not impact OT operations. Its asset visibility is good as well. This comprehensive feature set is crucial for our operations.…
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.

Quotes from Members

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

Pros

"The most valuable feature of the solution is asset tracking."
"Armis is very easy to implement due to its agentless design and offers a granular level of visibility for all assets in the network."
"Armis is a straightforward and user-friendly solution."
"Armis saves time by automating asset inventory management, allowing enterprises to quickly strategize by understanding their assets and exposures."
"Armis is easy to use."
"Armis is very easy to implement due to its agentless design and offers a granular level of visibility for all assets in the network."
"The solution’s vulnerability monitoring system is very good."
"It determines which assets and devices are at risk, alerts you if there's a risk, and categorizes all assets, including personal computers, mobile phones, servers, televisions, cars, and video game consoles."
"The threat prevention feature provides complete visibility."
"The solution's implementation and operation are very easy."
"It has helped with improving our security posture in terms of controlling the access of rogue devices into our network through identification. We have been able to prevent rogue device activities on the network, check the health of the system, and ensure remediation."
"The Forescout Platform's most valuable features include its agentless configuration, which allows for easy integration with switches, and its broad customizability of rules and conditions for policy configuration. By leveraging its Network Access Control capabilities, the tool controls network access, allowing administrators to enforce policies tailored to the organization's needs."
"We use the Forescout Platform for device visibility and control in our network. It's very helpful for tracking malicious or unusual activity. We use it to track which ports are open, which machines are running specific services, and to identify vulnerabilities. For example, there was a vulnerability related to SMB, and we could use the product to determine which machines inside our organization were allowing SMB traffic."
"The most valuable feature of Forescout Platform is that it has everything that Aruba has at significantly less cost."
"When users don't have the required updates, security patches, and antivirus, the tool blocks them from our network."
"Forescout is easy to integrate with a lot of end systems."
 

Cons

"There are occasional issues with some built-in integrations that require troubleshooting, particularly with DHCP integration. Developing additional integrations would be beneficial."
"The vulnerability assessment for Windows is not that great. It misses out on a lot of vulnerabilities."
"The solution's vulnerability testing could be improved."
"We have faced issues with the tool's stability."
"Armis could improve its geographic spread and marketing campaigns across regions."
"Like any IT tool, continuous learning and improvement are essential for the solution."
"Armis doesn't have a back intel feature."
"We face issues during implementation."
"Other solutions have TACACS+, but Forescout does not. In the next release, I would like to see Forescout have accounting."
"As a product, there is nothing to complain about. However, they should improve their overall support. You need that level of knowledge, that level of information is clearly not available. First and foremost, that information is not accessible. The second point to mention is that once you purchase the later support and services. That is, they will continue to charge you for every service."
"The product may not yield any return on investment since it is only used to make your environment more reliable and secure."
"For the user, the policy that they have implemented sometimes needs adjustments. Sometimes the features that the customer asks for aren't involved in the main installation, and I need to bolt an add-on in. However, I never know if this policy is the right one when I do this."
"Definitely, having more third-party integration would be an improvement."
"The cost is too high."
"They need to handle their Tier 1 cases differently. The biggest negative regarding Forescout is their support. Not having the ability to get instantly transferred to a support engineer for Tier 1 cases is pretty ridiculous."
"Custom integrations need to be better."
 

Pricing and Cost Advice

"The tool is cheap."
"It's about $160,000, but I'm not sure how long that is for or what it includes. Because we were a test base, we were provided with servers, but now, Forescout wants us to buy servers because those servers are now end-of-life or end-of-service. For our lifecycle management program, in order to get a refresh on those servers, we would have to buy servers or use our own network resources to house Forescout. Forescout takes up about 13 or 14 virtual CPUs."
"Forescout is more expensive than Cisco because Cisco gives high discounts."
"Devices with multiple IP's count multiple times against your license count."
"The cost of licensing for this product is quite high, but this cost covers all the features of the solution so it is a single payment for the term that has been selected."
"They base the license on the number of devices, which is quite misleading."
"The setup cost, pricing, and licensing are on the high side."
"The price of Forescout is reasonable when compared to Cisco ISE."
"Time savings in finding rogue devices as well as identifying potentially unwanted devices on the network has saved the organization time and money."
