Allows to upload necessary firmware to your device and perform the upgrade
With OpenText Network Automation, firmware can be uploaded for specific devices. If you need to upgrade a device, you can use this tool, though it may not apply to all devices. The software allows you to upload the necessary firmware to your device and perform the upgrade. Additionally, it enables you to check multiple devices for specific configurations and automates the search process and the configuration of multiple devices.

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

"It's great because you have a one-unit solution to aggregate network data, so it's one entry point for getting all the configuration into the same dashboard or same application."
"Pushing the network configuration to bulk devices. This saves a considerable amount of time that the engineer spends in pushing the network configuration."
"When compared with SolarWinds, it is more user-friendly, and tasks can be completed more quickly."
"Micro Focus tools are mature tools, that are well developed."
"We're able to set security policies and configure devices exactly how we want them."
"With OpenText Network Automation, firmware can be uploaded for specific devices. If you need to upgrade a device, you can use this tool, though it may not apply to all devices."
"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."
"One of the big improvements between the NSX-V and NSX-T is that in NSX-T you are no longer dependent on V-Center anymore."
"You can easily integrate this with other VMware products. It is a robust solution."
"Apart from the normal functionality, a few things are quite useful, including multi-cloud networking, container networking, and load balancing, which are quite useful when we are designing a solution, and it's a pretty mature platform right now."
"VMware NSX has the ability to create networks in software."
"The solution is very stable; there are no bugs or glitches, it doesn't crash or freeze, and it's reliable."
"The microsegmentation is a good feature, and you can segment details, products, or hardware information."
"It is easy to implement it."
 

Cons

"We've found some problems that may or may not have to do with our infrastructure. There are also some software defects that we've found."
"When compared to other automation tools that are available in the market, more can be done to improve this solution."
"The tool performs slowly."
"We just spoke with some of the product managers. We are getting some serious performance issues that have some serious repercussions for support."
"Compatibility of the devices needs to be enhanced, as it seems to be limited."
"Level one administration task can be defined in Micro Focus Network Automation but it could be more simplified."
"There is room for improvement in VMware NSX's workload management, particularly in the orchestration layer and in managing workloads across multiple clouds."
"I have no complaints regarding the user interface or any technical issues."
"The product is quite complex and that could be an area where improvements could be made."
"It might be nice to have more AI in the future."
"The support from VMware NSX could improve."
"Because NSX is software, it cannot match dedicated physical hardware in terms of performance, however this weakness is balanced with flexibility and scale."
"There are sometimes mismatch in the control, the details and what you actually see on the transport note."
"The initial setup for VMware NSX is a bit complex; it's not as simple as it could be."
 

Pricing and Cost Advice

"Pricing is reasonable, but if you compare it with other network Operation Management tools that are available on the market, it's expensive."
"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."
"We have saved man-hours and decreased our security exposure."
"Pricing and licensing could be improved as we are a government entity. Lower pricing could always help."
"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."
"This solution requires a licence."
"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."
"We are using the free version of the solution."
"The subscription is on a yearly basis."
