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 most valuable features of the Forescout Platform are NAC for sharing, Network Access Control, and port sharing of the devices."
"This solution can be used to organize guest portals, integrate switches, and create policies, and some of its standard use cases also include completing key process upgrades and anti-virus of Windows OS."
"The solution is stable, very reliable, and scalable, with great technical support that is knowledgeable and responsive."
"Overall, I would rate Forescout Platform as eight out of ten. It's a complete solution, easy to manage, and I have faced no issues."
"The most valuable feature is the blocking of USB devices."
"Forescout CounterACT has allowed us to better open our access and control wireless access globally from our HQ. This allows us to monitor the network access for every office globally. This has improved overall security, reducing risk and opening up the opportunity to provide greater end user flexibility."
"The product is very easy to work with and easy to deploy."
 

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."
"Battled with the use of SNMP v1 instead of v2c Direct web interface rather than installation of a client."
"Customer support could be improved by providing direct assistance from Forescout employees or specialists at customer sites to enhance the support experience and effectiveness."
"When it comes to improving Forescout Platform, I have faced some issues recently, particularly with the switch integration part."
"The most common complaint I hear about Forescout is about their technical support."
"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."
"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."
"The integration with Sync can be improved. We would like to see better integration with some other popular vendors."
"The product needs to improve its support. I know a case that dragged on for about one and a half years. They eventually suggested professional services and closed the ticket. We followed their advice, engaging the account manager and professional service team, only to discover that the issue was a bug. After reopening the case, it's been about six months, and the problem still hasn't been resolved."

"The ROI is priceless."

"The solution’s pricing is fine."
"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."
"We have a very clear licensing model for business. I don't have to have a Ph.D. to be able to understand the licensing model as you might need for other solutions. If I know exactly what we want, it can tell you which license you need. The solution is easy for purchasing, ordering, and ease of deployment as well."
"The price of Forescout is reasonable when compared to Cisco ISE."
