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.

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

"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"They have a lot of support and specialists who can meet with the customer."
"The most valuable features are stability and low cost."
"Over the last two years, they've enhanced a lot, especially in regard to integration with OpenStack."
"The micro-segmentation and the ability to create policy rules are valuable."
"NSX can reduce costs and has good service. It is easy for you and your users to use."
"The initial setup was straightforward. It follows a certain structure and you won't miss a step. It's all on the same level, step by step."
"NSX extends Layer-2 scalability on Layer 3, covering the vRO and extending the capability on Layer 3 by decapsulating using a new mechanism. NSX-V was designed to use with VMware products and Success 360, providing more flexibility toward different levels of cloud, containers, and components. NSX-T gives you the ability to stretch your network across different view locations. If you have multiple sites, you can connect them using NSX-T."
"The alert features are the most valuable."
 

Cons

"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Support is an issue because they have a limited number of resources."
"The setup is complex and should be made easier."
"The solution could benefit from improvements in its pricing and scalability."
"The initial configuration and integration within our existing environment were not easy. The configuration process was a bit complex, specifically during the initial setup."
"Lacks integration with other solutions."
"I would like them to make integration with other vendors easier."
"I would rate NSX's stability eight out of ten - there's room for improvement."
"Occasionally the licensing is not very clear. They should make it easier to understand."
"The vendor should integrate a basic load balancer in future versions"
 

Pricing and Cost Advice

"It’s a single license platform."
"The cost of the solution is a bit high."
"VMware NSX is expensive and everything is licensed. We have to pay for each individual feature."
"We can't go without NSX, so it's invaluable from this perspective."
"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."
"The tool's pricing is reasonable."
"You can scale NSX if you have the resources, but it's usually expensive and complex to scale up."
"The product pricing ranges from medium to expensive. I rate the pricing a seven out of ten."
"If five is a good price and one is a high price, I would rate the price a one out of five."
