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

"Micro Focus tools are mature tools, that are well developed."
"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."
"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."
"We're able to set security policies and configure devices exactly how we want them."
"When compared with SolarWinds, it is more user-friendly, and tasks can be completed more quickly."
"The microsegmentation allows me to sleep at night. My job is reducing risk, plugging security holes, and working with the automated layer security. Even if somebody spins up a new server, it has to have a tag in NSX."
"The most valuable feature is the ability to create, develop, and deploy servers in minutes to hours, rather than days."
"The most valuable feature of VMware NSX is the load balancing and routing of firewall rules, and many of the features are beneficial."
"It is a stable solution...The solution's initial setup process was easy."
"This product is better for network security than Cisco ASA and Firepower."
"The microsegmentation is great, and the security team thinks it is great."
"What makes them unique is their range of discovery, the way they can effectively mimic actual PC or smartphone endpoints to examine malware behavior."
"It has reduced the number of people on the network team along with the system engineer involved in the security process, so it is valuable and we can't go without NSX, so it's invaluable from this perspective."
 

Cons

"We just spoke with some of the product managers. We are getting some serious performance issues that have some serious repercussions for support."
"The tool performs slowly."
"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."
"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 vendor should integrate a basic load balancer in future versions"
"It's not feature-rich."
"The initial setup for VMware NSX is a bit complex; it's not as simple as it could be."
"They have some limitations in the firewall features as compared to the on-prem or dedicated hardware appliance. They can add more features, such as IPS and IDS, to the cloud firewall."
"The solution could benefit from improvements in its pricing and scalability."
"The routing functionality needs to be improved, as there are lots of bugs in the system."
"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."
"Some disadvantages of VMware NSX include a price challenge due to the high licensing cost compared to competitors, and it may sometimes require a specific skill set."
 

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."
"It is an expensive product, but cheaper than some competing solutions."
"This solution requires a licence."
"The price is based on the virtual desktop infrastructure(VDI) side and also is dependant on the size of the environment. The price is expensive and it could attract more purchasers in smaller organisations if it was reduced."
"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."
"The price is pretty high."
"We are using a perpetual license to use the solution and we have support."
"The solution is free and the price for the support can be expensive."
