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.

Micro segmentation has strengthened zero trust security and isolates production from test environments
The advantages of VMware NSX include its micro-segmentation for internal security at the firewall and VM levels, which is very powerful and helps us comply with complete Zero Trust security models. We are able to achieve this and configure network level virtualization with no dependency on VLANs. Micro-segmentation helps improve our security significantly. We are not totally dependent upon our physical upfront firewall, and it makes sense to configure everything using VMware NSX, leading to multiple improvements in our organization. We moved from traditional networking such as VLANs from the firewall and switches to VMware NSX segmentation. We achieve one firewall per VLAN and can stop lateral movement such as ransomware control. The Zero Trust model is the main functionality and architecture it offers, allowing application isolation, such as having a separate production and test environment. Consistent networking and security policies across different environments have a major and very positive impact on our business operations, allowing us to achieve the security posture we want with compliance and regulations.

Quotes from Members

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

Pros

"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."
"...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."
"Once you install it you can virtually forget about it; it's very low-maintenance and high-protection."
"It has helped us tighten our security posture. Now, staff can only access things that they should be accessing."
"For other security professions who are looking for something which is low in cost that does microsegmentation, they should look at ShieldX."
"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."
"Very often, when new challengers come in, what they do is they end up coming in at a lower cost with more functionality."
"Our clients are very satisfied that we can limit ourselves to NSX without the need to purchasing additional network systems and physical devices."
"VMware NSX has the ability to create networks in software."
"It's pretty stable. Just deploy it and just forget about it."
"From my experience, VMware on a private cloud is a good choice."
"NSX can reduce costs and has good service. It is easy for you and your users to use."
"The ability to scale from different clouds. At the moment, the scalability of the product is the number one thing that I saw."
"The most valuable features are ease of use and user interface."
"Has a great firewall."
 

Cons

"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."
"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."
"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."
"The response time of the technical support team could improve. We also sometimes had the feeling that they didn't properly understand the issue."
"I would like to have automating reporting built into common service management platforms, such as JIRA, Serviceaide, and ServiceNow."
"It is a bit tricky to install the various components and to get it set up properly."
"I would like to see automation capabilities in the deployment process."
"The initial setup was a bit lengthy in the beginning."
"Lacks integration with other solutions."
"A room for improvement in VMware NSX is that it has some security vulnerabilities, which means my company has to apply the patches every once in a while."
"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."
 

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."
"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."
"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."
"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 this product is too high."
"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."
"The pricing model for VMware NSX is good."
"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 licensing fees are expensive and we pay on a yearly basis."
"The price of VMware NSX is very good compared to other solutions."
"VMware NSX is expensive and everything is licensed. We have to pay for each individual feature."
"I would rate the pricing of VMware NSX as seven out of ten"
