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 Segmentation has positively impacted my organization by segregating and stopping hackers from doing lateral movement from one application to another, which is a great feature that Illumio Segmentation micro-segmentation provides."
"Illumio serves as a single endpoint technology where I can implement various features, including a zero-trust network, north-to-south and east-to-west configurations, and micro-segmentation, all coming from one platform, which ultimately saves us time and money."
"The tool helps with my company's security posture."
"I would recommend Illumio to all sizes of companies."
"Overall, Illumio is a powerful tool for micro-segmentation and zero trust security that provides strong visibility, flexible policy management, and effective threat containment, enhancing an organization's internal security posture."
"Illumio does more than general security product, it provides East-West traffic flow visibility and auditorial log which benefits on daily operation and periodical auditing."
"The product provides visibility into how the applications communicate and how the network protocols are being used."
"The client is getting more security and is more confident in their network because they now have the micro-segmentation feature in their environment."
"It has helped us tighten our security posture. Now, staff can only access things that they should be accessing."
"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."
"The most valuable feature is the automatic scaling. With its microservices, it scales both up and down, depending on traffic and throughput."
"The Adaptive Intention Engine is fantastic. It allows us to develop security policies using the language of our internal customers. It's machine-learning applied to security workflows. That allows us to much more easily construct the policies that will protect those workflows."
"ShieldX makes it a lot easier and a lot simpler to define your policies and define your rules, and that greatly reduces the opportunity for user error."
"Once you install it you can virtually forget about it; it's very low-maintenance and high-protection."
"For other security professions who are looking for something which is low in cost that does microsegmentation, they should look at ShieldX."
"Very often, when new challengers come in, what they do is they end up coming in at a lower cost with more functionality."
 

Cons

"It requires a low-level re-architecting of the product."
"There should be an option to upgrade from the console to the latest version instead of performing manual upgrades. This would be more helpful to streamline processes."
"Illumio can be improved if we have more interactive sessions with the tech team."
"The product’s agents don't work very well in OT environments."
"So far, we haven't been too satisfied with the assistance they've provided."
"Technical support could be better. When we get a reply from support engineers, it is not kind or empathetic."
"Sometimes, the PCE experiences slowness, especially when deploying around 300,000 endpoint devices."
"The interaction we've had with the support team hasn't been ideal. Technical support should be improved."
"I would like better reports and in-depth reporting."
"We are having some issues with their LDAP and integrating it with the Active Directory. We can't seem to set it up."
"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."
"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."
"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."
"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

"The product's pricing is around 10,000-15,000 USD. The pricing is on a yearly basis."
"There is a subscription needed to use Illumio Adaptive Security Platform and we pay every three years. Overall the solution is expensive."
"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."
"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."
"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."
"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."
"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."
