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.

Has improved network visibility and security through micro-segmentation and SDN capabilities
This feature gives us flexibility and allows us to manage everything under one pane. We can see everything on one console, including network operations and behavior. Monitoring and security are among the best features for VMware NSX. For micro-segmentation, it's integrated with our endpoint security. If there are any issues with servers or VMs, it notifies us so we can isolate the servers and investigate. It provides distributed security features such as firewall and intrusion, IDS, IPS. The security level with IPS and IDS in VMware NSX is excellent. It also provides logical switching and routing which gives an extra layer for Layer 2 and Layer 3 switching requirements. The solution provides flexibility, automation, and self-service capabilities, resulting in cost savings as extensive expertise isn't required. Once automation and self-service are implemented, many tasks can be completed automatically. Load balancing is another excellent feature. Multiple servers can run on load balancing features, which is particularly useful since we have many application servers running. Sharing loads between servers provides the best performance.

Quotes from Members

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

Pros

"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."
"We were able to see what devices are talking to each other, giving us more visibility."
"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."
"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."
"Very often, when new challengers come in, what they do is they end up coming in at a lower cost with more functionality."
"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."
"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."
"The stability is great. That's one of the things that we can quantify and leverage through NSX, because it's less complex. We have the availability to manage multiple things at the same time. You can identify problems before they manifest."
"This is the most scalable product of its type."
"The security offered by VMware NSX is the most valuable, plus it's a feature-rich product that's straightforward to install and configure."
"I really like the management dashboard, the tailor-made assurance, the telemetry, and the ease of integration with all other solutions of VMware, such as vSphere."
"The most valuable and unique feature of the solution is Micro-segmentation achieving better security, through enabling security architects to divide data centre into different segments, one being the VMS within the on-premises, the other one on the Cloud."
"The solution is a very, very good product that is perfect for customers who have good technical support."
"The most valuable features are its security aspects, especially the IPS and IDS for intrusion detection and protection."
"I have found the system to be very intuitive, functional, and they have great technology."
 

Cons

"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."
"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."
"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."
"I would like better reports and in-depth reporting."
"The next release of NSX should try to make Kubernetes and container integration a little easier than it is now. It's quite a complicated process."
"They have some limitations in the firewall features as compared to the on-prem or dedicated hardware appliance. They can add more features, such as IPS and IDS, to the cloud firewall."
"The solution is quite complex."
"If you compare NSX to a similar solution you might find it to be a bit more complex."
"If you're worried that NSX is too complex, I would tell you to take another look. If you compare NSX to a similar solution you might find it to be a bit more complex. Usually, the guy that comes in to implement NSX isn't the network guy and will lack the knowledge for the program. He can lack the knowledge for this program and will therefore think it's complex. You need somebody with network experience."
"This solution is really unusable from my perspective at this point. Overall, I would rate the solution a one of ten."
"We had some complexities implementing into the other parts of a network."
"The ticket support response time from VMware could be improved. Often, callbacks are delayed, which can be problematic if the servers are in production."
 

Pricing and Cost Advice

"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."
"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."
"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 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."
"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."
"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."
"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."
"The price is significantly high and it can be a hurdle for many potential users."
"The price is pretty high."
"We haven't had to hire a dedicated network engineer because NSX handles 90 percent of it. The reduced overhead in terms of managing networks has been the biggest plus."
"The solution is reasonable at the local level."
"The solution is very expensive."
"We are using the free version of the solution."
"The price of this product is too high."
"The licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price."
