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.
DanielBass - PeerSpot reviewer
Improves network security with micro-segmentation but setup is complex
I value the ability to dynamically configure our network on the fly using VMware NSX. This flexibility is a huge advantage because it allows us to avoid static configurations that come with traditional hardware setups. Additionally, the micro-segmentation feature is beneficial for adhering to strict security regulations from our security department.

Pros

"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 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 has helped us tighten our security posture. Now, staff can only access things that they should be accessing."
"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."
"...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."
"The most valuable feature is the automatic scaling. With its microservices, it scales both up and down, depending on traffic and throughput."
"We were able to see what devices are talking to each other, giving us more visibility."
"It's what we use the CIS Benchmarks for. It's for employing hardening rules and keeping them up to date when things happen on our systems. So it's really configurations and stuff that harden and report back."
"Overall, I would say the solution has been quite stable."
"Has a great firewall."
"The solution's customer service is good."
"The initial setup was straightforward. It follows a certain structure and you won't miss a step. It's all on the same level, step by step."
"The organization of it is logical, useful, and intuitive."
"Though I haven't been working a lot on VMware NSX, it's good to have. What I like the most about it is that its console is good, and it doesn't take a lot of effort in terms of doing my daily tasks on it or what it's meant for. VMware NSX is still a preferred product in the market."
"The dashboard is comprehensive and easy to use."
 

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. 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."
"I would like better reports and in-depth reporting."
"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."
"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."
"The initial configuration and integration within our existing environment were not easy. The configuration process was a bit complex, specifically during the initial setup."
"VMware NSX could improve by having more compatibility with other none Window-based operating systems."
"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."
"We've have had good and bad experiences with them. We don't always find them to be so impactful. Sometimes the support guy isn't so on top of resolving the issue and it can take a while to sort out."
"Since most people are very much used to physical networking, they find it difficult to use VMware NSX in the initial stage."
"The price is rather high."
"Occasionally the licensing is not very clear. They should make it easier to understand."
"The cost of the solution has room for improvement."
 

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."
"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."
"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 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 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."
"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."
"The licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price."
"The implementation of VMware NSX can be cost-intensive, especially if an organization is looking for a comprehensive solution. The costs can vary based on factors like the level of conversation and discounts obtained during negotiations. Some government organizations, for instance, may find the prices relatively high, leading to concerns about budget hikes, especially when deploying the solution across the entire organization. Regarding maintenance and support, they are typically included in the standard licensing costs for enterprise-level businesses. While these costs can be significant, many companies opt for standard licensing to ensure they have access to necessary support and maintenance services."
"The solution is very expensive."
"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."
"I would rate the pricing of VMware NSX as seven out of ten"
"The solution is reasonable at the local level."
"Our customers have definitely complained about its cost. It's expensive. I'd rate it a nine out of ten in terms of pricing where ten represents a high price. There are other products out there that are equally expensive."
"The price of VMware NSX is very good compared to other solutions."
