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."
"Provides flexibility to deploy and have network virtualization on different types of firewalls."
"The firewall is its most valuable feature."
"From a security standpoint, the customer was able to better secure critical workloads while routing L2/L3 worked normally, giving them more confidence that they would be ready for any potential security incident mitigation or outage (DR)."
"Any administrator with basic networking knowledge, in a couple of days, can be in full control of their networking without going through a networking engineer."
"The most powerful feature of VMware NSX is the micro-segmentation that allows us to separate the different protocols our application works with."
"One significant advantage of VMware NSX is the ability to provide advanced security at the micro-level, focusing on securing applications and workloads rather than just the network structure or virtualization-based network security."
"The most valuable features are the micro-segmentation and integrated security options."
"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."
 

Cons

"Sometimes, Airgap Zero Trust Enterprise hangs, requiring a process restart."
"Despite being somewhat behind in the cybersecurity field, VMware should develop a cloud and a red team to continuously monitor for new malware and ransomware."
"There are always issues integrating with Cisco."
"We would like tenant segmentation available in future releases."
"The initial setup for VMware NSX is a bit complex; it's not as simple as it could be."
"The reporting functionality could be better, and there could be an easier way of forwarding events. There's room for improvement in the product."
"The next release of NSX should try to make Kubernetes and container integration a little easier than it is now. It's quite a complicated process."
"The training costs a minimum of $3,000, which is expensive and should be reduced."
"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

Information not available
"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."
"VMware has a subscription and perpetual license. In the New Year, they're changing many things about the licensing model. Previously, NSX was licensed according to the number of sockets inside the appliance, so we bought VMware licenses based on that. However, that may have changed this year. We are still contacting the vendors to understand the new licensing strategy."
"VMware NSX is expensive and everything is licensed. We have to pay for each individual feature."
"The licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price."
"The price could be better. We pay for the license every three years. The last time I checked, it cost around three million pesos in the Philipines. Most of the expense will go towards implementation and renovation."
"Pricing and licensing could be improved as we are a government entity. Lower pricing could always help."
"The solution is free and the price for the support can be expensive."
"You can scale NSX if you have the resources, but it's usually expensive and complex to scale up."
