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 security offered by VMware NSX is the most valuable, plus it's a feature-rich product that's straightforward to install and configure."
"VMware NSX's overlay network is its most valuable feature, as it aligns with any network philosophy and allows for efficient addressing mechanisms. Additionally, the ability to extend the on-premise network into the provider space is beneficial. There are many features provided."
"The solution is very stable; there are no bugs or glitches, it doesn't crash or freeze, and it's reliable."
"Has a great firewall."
"Overall, for me, it's a good solution and has been working well."
"It's what we use the CIS Benchmarks for. It's for employing hardening rules and keeping them up to date when things happen on our systems. So it's really configurations and stuff that harden and report back."
"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."
"I have found the system to be very intuitive, functional, and they have great technology."
 

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 price is rather high."
"The vendor should integrate a basic load balancer in future versions"
"The response time of the technical support team could improve. We also sometimes had the feeling that they didn't properly understand the issue."
"There could be an improvement in regards to security. This solution cannot migrate all assets smoothly and continuously, for example, sometimes the physical hosts are not able to be converted into virtual ones, which needs to be fixed."
"Just being more knowledgeable about the different functions."
"One aspect that needs improvement is the need for further automation."
"It still needs to grow. There are still some features that it doesn't do, like it doesn't do multicasting."
"The price could be better. The non-enterprise version of the product should also be improved. I would like VMware to expand beyond the network and provide some VLAN technologies and more. I think we have one, but it's more on the distribution side because it's more on the upper side of the network. I'm looking forward to that."
 

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 solution is reasonable at the local level."
"We have saved man-hours and decreased our security exposure."
"The price of VMware NSX is very good compared to other 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 this product is too high."
"Our customers have definitely complained about its cost. It's expensive. I'd rate it a nine out of ten in terms of pricing where ten represents a high price. There are other products out there that are equally expensive."
"I was not involved in the purchase of the solution but I hear it is on the expensive side."
