Network and Security Engineer
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."
"It gives us a clear initial and secondary view of what's happening on our network to determine its health."
"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."
"I have noticed that in the last year the license model has changed from licensing the whole appliance to licensing the number of devices. It's more simple for a large installation, or a user to have CounterACT as their peripheral site in the company. It's a good choice to have changed the license policy."
"The stability is amazing for the Forescout Platform. We have been using Forescout for four years, and no one complained about the stability."
"Forescout Platform is stable, it is great."
"The threat prevention feature provides complete visibility."
"The most valuable feature is the ease of deployment, which does not require the use of an agent."
"The initial setup is quite simple. It's not too complex or difficult to set up."
 

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."
"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 initial setup was complex, but that was due to the nature of the network architecture."
"They should improve features related to IT security. ForeScout should analyze behavior to see if the behavior is malicious behavior and block this device. They should develop the ability to analyze the behavior of the device in my environment."
"The reporting could be improved."
"I should be able to integrate my Forescout with any other third party security technology, to build that connected security strategy."
"When adding what is in scope to a policy, it would be nice if you could select multiple policies instead of one policy at a time to add what is in the scope for network segmentation. I have found that during the install and configuration of the policies that if you want to modify multiple policies or enable multiple policies that you need to define what is in the scope (IP range or segments) one rule at a time. This caused some slow downs when implementing policies."
"The solution should include integration with other firewalls."
"The integration with Sync can be improved. We would like to see better integration with some other popular vendors."
 

Pricing and Cost Advice

Information not available
"The solution’s pricing is fine."
"For one license, we pay around 3,000 Indian rupees."
"We paid between $20,000 and $25,000 for a three-year license with maintenance."
"The pricing structure should be enhanced."
"The ROI is priceless."
"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."
"We went with the virtual appliance option. The biggest cost to running these types of appliances would be to either have multiple virtual appliances at every data center or running Remote SPAN hardware to provide you the real-time network visibility."
"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."
