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

"We were able to see what devices are talking to each other, giving us more visibility."
"...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."
"It has helped us tighten our security posture. Now, staff can only access things that they should be accessing."
"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."
"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 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."
"You can easily integrate this with other VMware products. It is a robust solution."
"Visibility, because on our environment, it's impossible mapping end to end, and we don't have any tools that provide this integration."
"VMware NSX is a stable solution; it's very reliable."
"The organization of it is logical, useful, and intuitive."
"We are happy with the scalability."
"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."
"VMware NSX offers some of the best features for security, such as micro-segmentation."
"NSX helps us by making IT management and operations more efficient. When VMs spin off from the DC to the DR site, all required settings on the network level are handled automatically."
 

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."
"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 would like better reports and in-depth reporting."
"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."
"We are having some issues with their LDAP and integrating it with the Active Directory."
"The one criticism I might have is there should be a bit more customer care, with regular review meetings on it or regular reports."
"I have no complaints regarding the user interface or any technical issues."
"It could be more user-friendly, but it's manageable. When we add a specific node to this particular NSX and the configuration changes, it won't push through the errors where required, but it'll accept it. However, while using it, we will have issues. It can also be more stable."
"It's not feature-rich."
"The price is rather high."
"There could be an improvement in regards to security."
"The engineering team has room for improvement. They should have have more of a Knowledge Base about different case studies and should develop more advanced features. These kinds of improvements will change the way things get done."
"There are always issues integrating with Cisco."
"It isn't easy to deploy."
 

Pricing and Cost Advice

"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 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."
"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 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 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."
"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."
"If five is a good price and one is a high price, I would rate the price a one out of five."
"The pricing is higher than other options from Palo Alto, Fortinet, and Cisco because it is sold in a bundle."
"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."
"Pricing and licensing could be improved as we are a government entity. Lower pricing could always help."
"We are using the free version of the solution."
"The tool's pricing is reasonable."
"The product pricing ranges from medium to expensive. I rate the pricing a seven out of ten."
"The licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price."
