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."
"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 visibility is the main benefit; we now know how many devices are connected, what the use for each device is, and what kind of devices we have in our environment."
"Forescout is a very good company that delivers very good features."
"We use it to prevent malicious activities on our network that potentially infiltrate it."
"The most valuable feature for us is the visibility into all connected devices."
"It's one of the tools that has given the federal government visibility into network devices and everything."
"The valuable feature of the product stems from the fact that it is easy to implement."
"This is clearly the best product for the NAC use cases in this field for Forescout."
 

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."
"Detection and control of Dual-Homed devices needs to be improved, as the product sometimes gives false positives."
"The installation is not secure because it takes high admin privileges."
"Search - needs boolean functionality (or pseudo operand now working)."
"I would rate this solution 7 out of 10."
"For improvements, I think technical support could be enhanced. The time zone difference makes remote support difficult - I'm in Indonesia, and they're in the US. Maybe the Forescout Platform could provide engineers from Asia Pacific."
"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."
"Initially, the implementation of the Forescout Platform took some time to figure out. The reason is we are a manufacturing unit and we have certain silos that are insulated areas where certain systems will not connect to the internet or to the LAN. Since there are many parts of it, we have to have an inclusive view of all those systems. It took a while for us to initially implement, but after a few months, everything worked well."
"When we automate an email to send to a user, sometimes it gets blocked, but that has nothing to do with Forescout. It depends on the mail gateway that we use or integrate with."
 

Pricing and Cost Advice

Information not available
"The cost of the solution depends on the customer's requirement because the customer is asking for different integration with a different product. Forescout Platform's price would start to get a bit higher. However, overall the price is a little expensive. It's can fit within the customer budget."
"I would rate Forescout Platform's pricing as four out of five."
"Forescout Platform is too expensive, so the price should be reduced."
"It's about $160,000, but I'm not sure how long that is for or what it includes. Because we were a test base, we were provided with servers, but now, Forescout wants us to buy servers because those servers are now end-of-life or end-of-service. For our lifecycle management program, in order to get a refresh on those servers, we would have to buy servers or use our own network resources to house Forescout. Forescout takes up about 13 or 14 virtual CPUs."
"The price of the Forescout Platform is expensive. I purchased it for approximately 94 lakhs."
"You can have a flexible license depending on your environment."
"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 tool's pricing is expensive but reasonable."
