Security monitoring has uncovered unauthorized devices and now protects client networks
I think the best feature of Armis Centrix for OT/IoT Security is that it ensures only the authorized devices and users are authorized to prevent any potential breaches. I think that clear definition is very essential for a lot of networks because it helps us understand who should be there and who shouldn't be. For our clientele, we were able to discover a lot of unauthorized devices that were on their network. This first of all helped them remove a lot of potential security breaches and cleared the bandwidth of the network as well. I think this has been one of the biggest cases that we have found. For most of the clients where we have deployed it, this has always been a common occurrence because a lot of people enter the network and then you don't know who is there, who has the access, and so on. I think this is the very reason I said what I said earlier.

Comprehensive visibility has strengthened endpoint control and automated threat response across networks
When it comes to improving Forescout Platform, I have faced some issues recently, particularly with the switch integration part. When integrating a switch, it asks for the vendor type, and often it does not match. For example, one series of HP switches may not be found in that vendor list. This leads to frustration because you have to check again with different HP models, and once you integrate a switch, you cannot edit the vendor list without removing it. Other issues are being worked on, particularly related to switch integration. I believe they will be fixed in the next upgrade or patch fix. There are no major issues, but the configuration changes needed for the switch model are necessary, and I think it would help if during integration, an admin user could check the password or credential used, as they currently cannot see the password after it is entered and saved.

Pros

"I think the best feature of Armis Centrix for OT/IoT Security is that it ensures only the authorized devices and users are authorized to prevent any potential breaches."
"The initial setup is quite simple. It's not too complex or difficult to set up."
"The user management has been very easy for the most part."
"The standout strength of this solution lies in its unique capability to effectively manage unmanaged switches."
"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."
"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."
"The most valuable features of the Forescout Platform are NAC for sharing, Network Access Control, and port sharing of the devices."
"When users don't have the required updates, security patches, and antivirus, the tool blocks them from our network."
"ForeScout provides some of the greatest visibility into network traffic, showing you exactly who is doing what, down to the port and protocol being used, capturing entire conversations between endpoints."
 

Cons

"I'm not exactly sure how scalable it is if you're managing multiple locations, but I think it still has some potential for improvement for multiple locations."
"It needs easier integration to other partners that automate functions within the security phase."
"The solution's customer support is bad and should be improved."
"The licensing costs are quite high. With the amount of hardware we have, we need too many licenses to make the product effective and it's ultimately just too costly."
"It does not support the TACACS+ protocol."
"In the next release of the solution, it could benefit from being more flexible to allow for more freedom."
"We experienced some detection issues when checking compliance for the Sophos agent."
"The configuration of the rules is both a blessing and a curse. While it is almost infinitely configurable, knowing how to get the product to do what you want it to do can be difficult, especially at first."
"In terms of technical support, their engineering team is very rigid."
 

Pricing and Cost Advice

Information not available
"You can have a flexible license depending on your environment."
"The ROI is priceless."
"They base the license on the number of devices, which is quite misleading."
"We might have paid in the ballpark of $20,000 yearly for our licenses. I do not recall there being other fees over and above the standard licensing fee."
"The fact that we were allowed to spin up as many servers as we had need of to support our geographic requirements while paying for licensing as an enterprise truly set Forescout apart from the crowd and improved the way we could design our access."
"It might not be the cheapest solution, but you get what you pay for."
"For one license, we pay around 3,000 Indian rupees."
"5,000 user licenses will cost you between seven and eight million dollars, compared to 20 million for Aruba."
