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 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."
"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."
"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."
"...It takes the exact same policies that you would apply to your on-premise environment and enables you to simply apply them to the cloud. It becomes one policy for both on-prem and for the cloud."
"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."
"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."
"This product is better for network security than Cisco ASA and Firepower."
"VMware NSX is a very good solution. It's also a scalable solution."
"Automation, because we're constantly onboarding massive customers. We have our own management system, which integrates nicely with NSX. Therefore, we've built an automation layer so we can deploy and completely secure new customers in a hosted environment within a couple of minutes."
"VMware NSX has improved our customers' organizations through its automation of security policies, delivery of policy by intent, rapid provisioning, and removing security as being a blocker."
"The most valuable feature of VMware NSX is the load balancing and routing of firewall rules, and many of the features are beneficial."
"It has reduced the number of people on the network team along with the system engineer involved in the security process, so it is valuable and we can't go without NSX, so it's invaluable from this perspective."
"The most valuable feature of VMware NSX is the ability to set up virtual networking environments."
"It's very effective in how easy it is to manage and orchestrate all the different devices with the different types of requirements we have."
 

Cons

"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."
"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."
"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."
"We are having some issues with their LDAP and integrating it with the Active Directory. We can't seem to set it up."
"The integration with other brands is not the best and could be better."
"VMware NSX could improve by having more compatibility with other none Window-based operating systems."
"It might be nice to have more AI in the future."
"The solution can improve by making it more straightforward, easier to install and maintain in the environment."
"Sometimes we face issues when a server is compromised or we have an infection. The isolation feature helps, but we need to work more on this aspect."
"An area for improvement in VMware NSX is that it uses up more resources and is heavy on the network. What I'd like to see in the next release of the solution is more automation."
"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."
"Nowadays, NSX supports the KVM and ESXi hypervisors only. It should also support Hyper-V and Citrix hypervisors."
 

Pricing and Cost Advice

"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 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."
"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."
"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."
"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."
"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."
"The price of VMware NSX is optimal. Additionally, the price of the solution can be negotiated with the vendor. Many areas of the solution can impact the cost, such as features, time for onboarding, and support needed."
"The price is significantly high and it can be a hurdle for many potential users."
"You can scale NSX if you have the resources, but it's usually expensive and complex to scale up."
"The solution is reasonable at the local level."
"We are using the free version of the solution."
"The price could be better. We pay for the license every three years. The last time I checked, it cost around three million pesos in the Philipines. Most of the expense will go towards implementation and renovation."
"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."
"If five is a good price and one is a high price, I would rate the price a one out of five."
