Correlates incidents, allows for quicker identification and helps prioritize investigations
The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

Improves network security with micro-segmentation but setup is complex
I value the ability to dynamically configure our network on the fly using VMware NSX. This flexibility is a huge advantage because it allows us to avoid static configurations that come with traditional hardware setups. Additionally, the micro-segmentation feature is beneficial for adhering to strict security regulations from our security department.

Pros

"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"It can integrate with almost any cybersecurity tool available in the market."
"It's very important for them to have small footprints and have as much services in their servers, as possible."
"The microsegmentation is great, and the security team thinks it is great."
"It's a beneficial tool."
"I have found VMware NSX to be easy to use."
"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 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 organization of it is logical, useful, and intuitive."
"VMware NSX has the ability to create networks in software."
 

Cons

"Support is an issue because they have a limited number of resources."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"They could do more with cloud management."
"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 had some complexities implementing into the other parts of a network."
"NSX could better integrate with open-source products. Of course, it integrates with some, but I know many people are uncomfortable deploying NSX with certain open-source solutions, such as Radar."
"The network-extending capabilities for the physical environment need improvement."
"The cost of the solution has room for improvement."
"The vendor should integrate a basic load balancer in future versions"
"Everybody needs a network to connect to, and VMware doesn't readily provide one."
 

Pricing and Cost Advice

"It’s a single license platform."
"The price is significantly high and it can be a hurdle for many potential users."
"The price of VMware NSX is very good compared to other solutions."
"We are using a perpetual license to use the solution and we have support."
"VMware NSX is a cheaper product compared to its competitor, Cisco."
"The cost of the solution is a bit high."
"We haven't had to hire a dedicated network engineer because NSX handles 90 percent of it. The reduced overhead in terms of managing networks has been the biggest plus."
"We can't go without NSX, so it's invaluable from this perspective."
"The solution is free and the price for the support can be expensive."
