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.

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

"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."
"The most valuable feature of VMware NSX is the DFW (distributed firewall)"
"Technically, VMware NSX is more advanced technology-wise when compared to others. We have been studying it and so far, so good. We know that the NSX product is superior when it comes to software virtualized networks. </p> <p>If you are looking to work with new and future technologies, then NSX is one of the best options. It costs less for power consumption since it will be a virtual network and not a pure physical network that consumes more energy."
"It does have capabilities of micro-segmenting a network, being able to create smaller segments of various types of applications separated by various tiers."
"Provides protection for virtual machines."
"Overall, I would say the solution has been quite stable."
"This is a good firewall and overall it is rich in features."
"It is a stable solution...The solution's initial setup process was easy."
"The most powerful feature of VMware NSX is the micro-segmentation that allows us to separate the different protocols our application works with."
 

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 scalability is not perfect."
"We would like tenant segmentation available in future releases."
"The reporting functionality could be better, and there could be an easier way of forwarding events. There's room for improvement in the product."
"The support from VMware NSX could improve."
"The integration with other brands is not the best."
"One drawback is this solution requires a lot of other products in the VMware ecosystem to have a full end-to-end operation orchestration monitoring. You have to buy a lot of add-ons to fully utilize the functionality."
"The initial configuration and integration within our existing environment were not easy."
"The network-extending capabilities for the physical environment need improvement."
 

Pricing and Cost Advice

"It’s a single license platform."
"The solution is reasonable at the local level."
"You can scale NSX if you have the resources, but it's usually expensive and complex to scale up."
"The subscription is on a yearly basis."
"The price of VMware NSX is very good compared to other solutions."
"VMware NSX is a cheaper product compared to its competitor, Cisco."
"The tool's pricing is reasonable."
"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."
"There is a license required for this solution and there is also a support license available. The price of the solution could be better."
