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 main feature, the NAC engine, is very flexible since ForeScout CounterACT doesn’t need the use of 802.1x and can work with almost all switch vendors."
"The most important feature is that this solution works well without a 802.1x feature, and you can use CounterACT to implement that feature and also have a very granular control of your devices, including shadow devices."
"The network access control is a valuable feature for us, as it provides endpoint visibility of our network and controls who can access network resources, which is really powerful."
"Forescout Platform has made it possible to block people working near our construction sites who should not have access to our network."
"The best parts of Forescout Platform are its orchestration features, discovery capabilities, classification buckets, and flexibility in creating policies."
"The support from the Forescout Platform is great."
"The standout strength of this solution lies in its unique capability to effectively manage unmanaged switches."
"The most valuable feature for us is the visibility into all connected devices."
 

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."
"The solution needs more definitive pricing. The costs are hard to nail down."
"The solution could always improve by adding more features to make it more robust."
"This solution is not that easy to scale but this depends on a company's needs."
"Forescout needs to improve its cloud management and remote connectivity."
"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."
"The solution's customer support is bad and should be improved."
"There were many issues with deployment, but these were largely due to our own network architecture issues."
"Search - needs boolean functionality (or pseudo operand now working)."
