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 pricing, technical support, stability, scalability, initial set up, interface, dashboards, management, and monitoring are fantastic."
"The most valuable feature for us is the real-time alerting of newly connected devices, whether they are approved or unapproved devices on our network."
"ForeScout is a powerful network access control tool that has some features found in insider threat solutions, though it is not exactly made for that."
"Customer service is above average and technical support is above average."
"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."
"The best parts of Forescout Platform are its orchestration features, discovery capabilities, classification buckets, and flexibility in creating policies."
"Obtaining visibility into the network and connected devices is very simple with this tool. It takes me three minutes to do a base deployment when all the parameters are available."
"My advice to others is Forescout Platform is a good solution; it's fairly simple to deploy in an environment, far better than the other products in which we have done a POC, and has good stability and performance."
 

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 ability to block external devices in Mac is lacking and needs to be added."
"The system controls could be better."
"I'd like to see improvements in the reporting aspect of Forescout Platform. While the dashboards are good, the reports are lacking and need enhancement, especially in terms of standardization and customization options. Apart from that, all the features and functionalities are working well without any issues."
"There are few issues with CounterACT that need more attention, mainly its ability to process and perform discovery faster."
"The installation is not secure because it takes high admin privileges."
"It does not support the TACACS+ protocol."
"The fact that Forescout Platform doesn't have a presence in the South African region is a weakness because of which you can't ask for help from them if you have any problems."
"Search - needs boolean functionality (or pseudo operand now working)."
 

Pricing and Cost Advice

Information not available
"It might not be the cheapest solution, but you get what you pay for."
"The product's pricing is reasonable."
"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 price of Forescout is reasonable when compared to Cisco ISE."
"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."
"You can have a flexible license depending on your environment."
"For one license, we pay around 3,000 Indian rupees."
"Licenses are perpetual but can come with renewable support."
