Featured Reviews

Atul-Yadav - PeerSpot reviewer
Implements real-time threat monitoring and reduces false positives with automated remediation
An area for improvement is in integrating AGentic architectures for retrieval-intensive applications in cloud infrastructures. Ensuring that Airgap Zero Trust Enterprise can work with AI agents and protect applications managed by them would be a significant enhancement. In addition, addressing the issue of the occasional hang could improve the product.
MagdyRaafat - PeerSpot reviewer
Enhanced security and streamlined management drive efficient connectivity
Open source is a standard solution where you take a gray box or white box and put the software from your end. You can do programming with Ansible and make the network work in the software-defined mode, providing automation and management capabilities. I am currently working with VMware. It integrates easily with everything and can work with any system. When discussing micro-segmentation, it enhances security, providing more secure data in your data center while allowing for extra layers of security outside your data center. If you have an ACI, there is communication between locations, keeping your data secure in your data center and throughout the path it takes, such as to SD-WAN or the cloud. I work with cloud solutions including AWS, Azure, GCP, and private cloud. My overall rating for VMware NSX is 8.5 out of 10.

Quotes from Members

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

Pros

"The return on investment has been significant, as Airgap Zero Trust Enterprise has proved to be cost-effective."
"Has a great firewall."
"The organization of it is logical, useful, and intuitive."
"I rate the scalability as ten out of ten."
"VMware NSX's overlay network is its most valuable feature, as it aligns with any network philosophy and allows for efficient addressing mechanisms. Additionally, the ability to extend the on-premise network into the provider space is beneficial. There are many features provided."
"Overall, for me, it's a good solution and has been working well."
"Overall, I would say the solution has been quite stable."
"NSX's stand-out function is the distributed firewall. The firewall system is just top-notch, and I haven't seen another solution like it."
"It's a beneficial tool."
 

Cons

"Sometimes, Airgap Zero Trust Enterprise hangs, requiring a process restart."
"I would like them to make integration with other vendors easier."
"If you're worried that NSX is too complex, I would tell you to take another look. If you compare NSX to a similar solution you might find it to be a bit more complex. Usually, the guy that comes in to implement NSX isn't the network guy and will lack the knowledge for the program. He can lack the knowledge for this program and will therefore think it's complex. You need somebody with network experience."
"We have done three installations and we have not had any critical issues. The time it took for the installation was approximately two days. However, they should provide better documentation."
"We would like better integration with the standards on the market. For example, with OSPF, their integration in NSX is very low. It's not a full OSPF integration. It is too thin from a protocol perspective."
"They need to enhance their technical support."
"The solution could benefit from improvements in its pricing and scalability."
"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."
"A faster resolution time would be beneficial."
 

Pricing and Cost Advice

Information not available
"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."
"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."
"VMware NSX is a cheaper product compared to its competitor, Cisco."
"VMware NSX is expensive and everything is licensed. We have to pay for each individual feature."
"I was not involved in the purchase of the solution but I hear it is on the expensive side."
"The pricing model for VMware NSX is good."
"It is an expensive product, but cheaper than some competing solutions."
"We have saved man-hours and decreased our security exposure."
