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.

Has improved network visibility and security through micro-segmentation and SDN capabilities
This feature gives us flexibility and allows us to manage everything under one pane. We can see everything on one console, including network operations and behavior. Monitoring and security are among the best features for VMware NSX. For micro-segmentation, it's integrated with our endpoint security. If there are any issues with servers or VMs, it notifies us so we can isolate the servers and investigate. It provides distributed security features such as firewall and intrusion, IDS, IPS. The security level with IPS and IDS in VMware NSX is excellent. It also provides logical switching and routing which gives an extra layer for Layer 2 and Layer 3 switching requirements. The solution provides flexibility, automation, and self-service capabilities, resulting in cost savings as extensive expertise isn't required. Once automation and self-service are implemented, many tasks can be completed automatically. Load balancing is another excellent feature. Multiple servers can run on load balancing features, which is particularly useful since we have many application servers running. Sharing loads between servers provides the best performance.

Quotes from Members

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

Pros

"When compared with SolarWinds, it is more user-friendly, and tasks can be completed more quickly."
"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."
"Pushing the network configuration to bulk devices. This saves a considerable amount of time that the engineer spends in pushing the network configuration."
"Overall, I would say the solution has been quite stable."
"Provides flexibility to deploy and have network virtualization on different types of firewalls."
"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."
"The most valuable features are ease of use and user interface."
"The microsegmentation is great, and the security team thinks it is great."
"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)."
"The stability is great. That's one of the things that we can quantify and leverage through NSX, because it's less complex. We have the availability to manage multiple things at the same time. You can identify problems before they manifest."
"The most valuable feature of VMware NSX is the ability to set up virtual networking environments."
 

Cons

"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."
"The tool performs slowly."
"We had some complexities implementing into the other parts of a network."
"If there are other solutions already in place, it can be difficult to implement."
"We would like tenant segmentation available in future releases."
"The support needs improvement."
"I would rate NSX's stability eight out of ten - there's room for improvement."
"The ticket support response time from VMware could be improved. Often, callbacks are delayed, which can be problematic if the servers are in production."
"The initial establishment can be complex."
"VMware NSX only supports some platforms like KVM."
 

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."
"We have saved man-hours and decreased our security exposure."
"I would rate the pricing of VMware NSX as seven out of ten"
"VMware NSX isn't cheap."
"It is an expensive product, but cheaper than some competing solutions."
"The price of VMware NSX is optimal. Additionally, the price of the solution can be negotiated with the vendor. Many areas of the solution can impact the cost, such as features, time for onboarding, and support needed."
"The price of VMware NSX is very good compared to other solutions."
"The cost of the solution is a bit high."
"You can scale NSX if you have the resources, but it's usually expensive and complex to scale up."
