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.

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."
"For other security professions who are looking for something which is low in cost that does microsegmentation, they should look at ShieldX."
"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."
"Very often, when new challengers come in, what they do is they end up coming in at a lower cost with more functionality."
"...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."
"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'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."
"It does have capabilities of micro-segmenting a network, being able to create smaller segments of various types of applications separated by various tiers."
"The solution is very stable and reliable."
"I have found some of the major features of this solution to be its ease of use, flexibility, and reliability."
"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."
"When you have a solid secure solution between your on-prem and cloud solution, then you're in a safe place."
"Firewall security is one of VMware NSX's vital features"
"With Lastline, the effort to put in into the protecting the users against zero-day threats and malware can be subsequently reduced."
 

Cons

"We are having some issues with their LDAP and integrating it with the Active Directory. We can't seem to set it up."
"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."
"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."
"The initial configuration and integration within our existing environment were not easy. The configuration process was a bit complex, specifically during the initial setup."
"The first time setting it up was difficult."
"The price is expensive and it could attract more purchasers in smaller organisations if it was reduced."
"The initial establishment can be complex."
"The NSX setup is complex. That's one area where they could improve."
"The routing functionality needs to be improved, as there are lots of bugs in the system."
"Our technical team is always looking for the solutions that they work with to offer more convenient integrations."
"If you compare NSX to a similar solution you might find it to be a bit more complex."
 

Pricing and Cost Advice

"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."
"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."
"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."
"You can scale NSX if you have the resources, but it's usually expensive and complex to scale up."
"We are using a perpetual license to use the solution and we have support."
"We are using the free version of the solution."
"The pricing model for VMware NSX is good."
"The solution is very expensive."
"The subscription is on a yearly basis."
"The solution is free and the price for the support can be expensive."
"The price of VMware NSX is reasonable."
