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

"The most valuable feature is the automatic scaling. With its microservices, it scales both up and down, depending on traffic and throughput."

"For other security professions who are looking for something which is low in cost that does microsegmentation, they should look at ShieldX."

"Once you install it you can virtually forget about it; it's very low-maintenance and high-protection."

"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."

"Very often, when new challengers come in, what they do is they end up coming in at a lower cost with more functionality."

"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 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."

More ShieldX pros

"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."

"I can definitely recommend VMware NSX to other users."

"The most valuable feature is to control application behavior, and it provides us with features that other products have not."

"During our experience, the solution has been stable."

"The most valuable features are stability and low cost."

"When you're talking about virtual networks, I think NSX is one of the greatest products and will soon be the leader in the market."

"The most valuable features are ease of use and user interface."

"From a distributed firewall perspective, it's a solid solution."

More VMware NSX pros

Cons

"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."

"I would like better reports and in-depth reporting."

"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."

"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."

"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."

"VMware NSX should be able to scale for different customers, even the big ones. Its scalability needs improvement. Stability for it should also be improved."

"The response time of the technical support team could improve. We also sometimes had the feeling that they didn't properly understand the issue."

"Some disadvantages of VMware NSX include a price challenge due to the high licensing cost compared to competitors, and it may sometimes require a specific skill set."

"I would like them to make integration with other vendors easier."

"I have no complaints regarding the user interface or any technical issues."

"Some configuration maximums are limiting to the user, especially when it comes to the deployment of very, very large environments."

"The technical support could use some improvement."

"We had some complexities implementing into the other parts of a network."

Pricing and Cost Advice

"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."

"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."

"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 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 price of VMware NSX is very good compared to other solutions."

"We can't go without NSX, so it's invaluable from this perspective."

"The licensing fees are expensive and we pay on a yearly basis."

"The price is based on the virtual desktop infrastructure(VDI) side and also is dependant on the size of the environment. The price is expensive and it could attract more purchasers in smaller organisations if it was reduced."

"The cost of the solution is a bit high."

"If five is a good price and one is a high price, I would rate the price a one out of five."

"VMware has always been geared towards enterprise and their pricing options are a bit high. Their price is higher than other options in the market."
