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 solution is easy to use and is good for management control."
"The micro-segmentation and the ability to create policy rules are valuable."
"The solution is very good at micro-segmentation."
"If the new user is looking for micro-segmentation in the network space, then VMware NSX is the best solution."
"The best part is the blueprint creation where I can create their things and then move on to the target environment."
"VMware NSX has improved our organization in the way that we can now deploy many VMs faster than before and so we are scaling up much faster."
"During our experience, the solution has been stable."
"The we can actually extend Layer 2 networking across datacenters, and also Layer 3 networking, which comes along with it."
 

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."
"The engineering team has room for improvement. They should have have more of a Knowledge Base about different case studies and should develop more advanced features. These kinds of improvements will change the way things get done."
"Nowadays, NSX supports the KVM and ESXi hypervisors only. It should also support Hyper-V and Citrix hypervisors."
"The price is expensive and it could attract more purchasers in smaller organisations if it was reduced."
"We had some complexities implementing into the other parts of a network."
"Lacks integration with other solutions."
"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."
"The licensing model is expensive and could be more flexible, especially after Broadcom bought VMware. It made it an expensive licensing model with no other options to take something specific from the license itself."
"I would like to have automating reporting built into common service management platforms, such as JIRA, Serviceaide, and ServiceNow."
 

Pricing and Cost Advice

"It’s a single license platform."
"The licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price."
"VMware NSX isn't cheap."
"There is a license required for this solution, we pay annually."
"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."
"The subscription is on a yearly basis."
"The solution is free and the price for the support can be expensive."
"The pricing model for VMware NSX is good."
"The licensing fees are expensive and we pay on a yearly basis."
