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

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

"It has helped us tighten our security posture. Now, staff can only access things that they should be accessing."

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

"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."

"...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."

"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."

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

More ShieldX pros

"VMware NSX is used for micro-segmentation, and if you have a virtual VMware pool then you can segment them separately, similar to a firewall for virtual micro-segmentation."

"It's a solid product. Very easy to use out-of-the-box."

"We have many advantages with the cloud infrastructure."

"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."

"It gives more security and micro-segmentation. It helps to set network configurations in an easy way."

"What makes them unique is their range of discovery, the way they can effectively mimic actual PC or smartphone endpoints to examine malware behavior."

"NSX extends Layer-2 scalability on Layer 3, covering the vRO and extending the capability on Layer 3 by decapsulating using a new mechanism. NSX-V was designed to use with VMware products and Success 360, providing more flexibility toward different levels of cloud, containers, and components. NSX-T gives you the ability to stretch your network across different view locations. If you have multiple sites, you can connect them using NSX-T."

"I really like the management dashboard, the tailor-made assurance, the telemetry, and the ease of integration with all other solutions of VMware, such as vSphere."

More VMware NSX pros

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."

"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."

"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."

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

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

"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."

"It needs to be cheaper."

"It's a good product, but the way that it has got so many multiple levels that need to be purchased makes it expensive and cumbersome."

"The licensing model is expensive and could be more flexible, especially after Broadcom bought VMware. It made it an expensive licensing model with no other options to take something specific from the license itself."

"NSX V has less security features than NSX T just so you are aware"

"It lacks full knowledge of physical side of the network topology."

"Traffic flow introspection topology visibility is definitely needed because at the moment, NSX-T lacks in this area."

More VMware NSX cons

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."

"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 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."

"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 licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price."

"The pricing is higher than other options from Palo Alto, Fortinet, and Cisco because it is sold in a bundle."

"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."

"VMware NSX isn't cheap."

"You can scale NSX if you have the resources, but it's usually expensive and complex to scale up."

"VMware NSX is expensive and everything is licensed. We have to pay for each individual feature."

"I'm unable to give information on the pricing or licensing cost of VMware NSX because I've never been someone who looks into the economic part of any security or virtualization solutions. That's handled by an entirely different team, and I don't even have the slightest idea about the costs associated with the solution, though I've heard pricing for VMware NSX is on the higher side."

"I would rate the pricing of VMware NSX as seven out of ten"
