Irfan Sharfi - PeerSpot reviewer
Security Professional at a tech vendor with 10,001+ employees
Micro-segmentation has transformed endpoint protection and now isolates internal threats effectively
Illumio can be improved in several areas based on our feedback. Sometimes, the PCE experiences slowness, especially when deploying around 300,000 endpoint devices. When these devices communicate within the network, loading the map or connections can cause latency, which needs improvement for a more user-friendly and faster experience. Regarding improvements to the interface, I believe we can add more features to the graphical user interface, such as proper logs. While the logs currently indicate what was blocked or allowed, clicking on a specific log should provide more information, such as which extra-scope rule is causing a denial, offering better analysis for troubleshooting.

Proactively monitors, blocks, and reports what it has blocked; and self-updates meaning there is zero maintenance
The most valuable feature is the automatic scaling. With its microservices, it scales both up and down, depending on traffic and throughput. The traffic through our website depends on holiday bookings. It's very quiet in November through January, and then our traffic picks up quite rapidly and, at our peak, we will take in excess of a million pounds of business a day through our website. The UI was also one of the huge selling points. My web development manager was blown away with the detail and the granularity that you can get out of the UI. It is a very strong and informative UI, with the amount of data it provides. Uptime on the system has been 648 days and we do very little to it because it self-updates and alerts. It does everything that we need it to do, so the administration side of it is zero. One of the beauties about ShieldX is that it's such a good "fire-and-forget" product.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Illumio definitely demonstrates its value in money-saving capabilities, enhancing our lateral environment inside the organization and providing effectiveness overall once integrated."
"The most valuable feature of Illumio Adaptive Security Platform is monitoring. When I have no requirement from the other application, I can use the web block traffic to build."
"Illumio Segmentation has had a positive impact on my organization, as it has created a very impressive impact because it is a worldwide operation."
"The client is getting more security and is more confident in their network because they now have the micro-segmentation feature in their environment."
"The Explorer allows you to know the traffic between source and destination."
"The flexibility of the solution is its most valuable feature."
"I would recommend Illumio to all sizes of companies."
"Everything is valuable in Illumio."
"For other security professions who are looking for something which is low in cost that does microsegmentation, they should look at ShieldX."
"It has helped us tighten our security posture. Now, staff can only access things that they should be accessing."
"We were able to see what devices are talking to each other, giving us more visibility."
"Once you install it you can virtually forget about it; it's very low-maintenance and high-protection."
"ShieldX has been designed from the very beginning to work well in cloud environments. It understands autoscaling, automation, and auto-configuration. These are the things which are important in today's operating environment."
"Very often, when new challengers come in, what they do is they end up coming in at a lower cost with more functionality."
"The UI was also one of the huge selling points. My web development manager was blown away with the detail and the granularity that you can get out of the UI. It is a very strong and informative UI, with the amount of data it provides."
"The most valuable feature is the automatic scaling. With its microservices, it scales both up and down, depending on traffic and throughput."
 

Cons

"So far, we haven't been too satisfied with the assistance they've provided."
"One area for improvement regarding Illumio might be making the policy management even more intuitive."
"The customer service is lagging a bit. It could be better."
"Technical support could be better. When we get a reply from support engineers, it is not kind or empathetic."
"Illumio Adaptive Security Platform could improve by supporting more operating systems. For example, Cisco and Apache appliances."
"Illumio supports both on-prem and cloud environments, but I think the GUI interface could be more user-friendly."
"Illumio does not have much in terms of application dependency mapping features."
"It requires a low-level re-architecting of the product."
"They need to be consistent in performance and capabilities over time, given the fact that this is new and I want to see where this goes in the next year or so. As the vendor continues to evolve and add future functionality, we want to make sure that we are still keeping up with the integrations, etc. Time will be the key factor here. The proper support for some of the latest technologies, Docker containers, etc. They need to keep up with threat landscape, so we will see how the security get layered. This is what we are going to be keeping an eye on."
"I would like better reports and in-depth reporting."
"With any kind of tool like ShieldX, where you're in the cloud instead of a traditional firewall, you're using CPU resources in those environments to provide the protection. So there's a cost associated with CPU resources. I'm pressing upon them to make the product much more efficient and use less CPUs to do the same thing."
"They need to be consistent in performance and capabilities over time, given the fact that this is new and I want to see where this goes in the next year or so."
"We are having some issues with their LDAP and integrating it with the Active Directory. We can't seem to set it up."
"There should be a bit more customer care, with regular review meetings on it or regular reports. It would be nice to have a quarterly or biannual review of what ShieldX has blocked."
 

Pricing and Cost Advice

"There is a subscription needed to use Illumio Adaptive Security Platform and we pay every three years. Overall the solution is expensive."
"The product's pricing is around 10,000-15,000 USD. The pricing is on a yearly basis."
"For a three-year deal we paid £55,000 plus tax... But, and this is a big "but," this was over two years ago. ShieldX had only just hit the market. We were the first company in Europe to buy ShieldX."
"ShieldX ensures that we can have the separation needed for our environment to avoid drastically increasing the cost on the licensing side. From this perspective, it's been very positive and helpful."
"We are very happy with the pricing and licensing. It's about getting a site-wide license. One of the challenges that we've had with our previous vendor had been the cost of licensing."
"Security policies are now applied as applications are going up. Because it's automated, we don't have the three to four week delay. The insertion of applications in the cloud for us dropped from an average of three to four weeks to a couple of days."
"We are actually expecting our costs to drop in the coming year, but it is just a matter of the licensing expiring. That is going to happen in the next six months or so. Then, we will start to see a decrease in overall spend."
"For other security professions who are looking for something which is low in cost that does microsegmentation, they should look at ShieldX. It might not be the big name out there, but it does everything that you are looking for in microsegmentation at a very low price."
"ShieldX also enables us to migrate to cloud environments faster. That is an important part of it for sure because it takes the exact same policies that we would apply to our on-premise environment and enables us to simply apply them to the cloud. It becomes one policy for both on-prem and for the cloud."
