Automated security monitoring increases efficiency, but market visibility needs improvement
I am currently evaluating Stellar Cyber Open XDR in terms of their support. I do not see any major areas for improvement as of now. Their support is good, and the team is small, enabling them to cater to everyone effectively. While I have not encountered significant drawbacks so far, market penetration is challenging due to the product's newness, despite its flexibility and customization features. I find their user interface to be quite good.

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 ability to set up virtual networking environments."
"It provides a single pane of glass. You can do the switching, routing, load balancing, IPS, IDS, etc. Everything is under one umbrella. So, there is no vendor dependency over there."
"The most valuable feature is the integration with the firewall."
"The solution is easy to use and is good for management control."
"The alert features are the most valuable."
"It's totally stable, because right now it's running version 6.3."
"The most valuable feature is to control application behavior, and it provides us with features that other products have not."
"The most valuable feature of VMware NSX is the DFW (distributed firewall)"
 

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 cost of the solution has room for improvement."
"The solution is quite complex. You need to keep your thinking cap on and know what you are doing: Go to the training and listen to the solution architects when they come in because they have a lot of knowledge."
"I would like to have automating reporting built into common service management platforms, such as JIRA, Serviceaide, and ServiceNow."
"This solution is really unusable from my perspective at this point. Overall, I would rate the solution a one of ten."
"The solution can improve by making it more straightforward, easier to install and maintain in the environment."
"They have some limitations in the firewall features as compared to the on-prem or dedicated hardware appliance. They can add more features, such as IPS and IDS, to the cloud firewall."
"It's a good product, but the way that it has got so many multiple levels that need to be purchased makes it expensive and cumbersome."
"VMware NSX could improve by having more compatibility with other none Window-based operating systems."
 

Pricing and Cost Advice

"It’s a single license platform."
"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."
"I would rate the pricing of VMware NSX as seven out of ten"
"Pricing and licensing could be improved as we are a government entity. Lower pricing could always help."
"The solution is free and the price for the support can be expensive."
"If five is a good price and one is a high price, I would rate the price a one out of five."
"The price is based on the virtual desktop infrastructure(VDI) side and also is dependant on the size of the environment. The price is expensive and it could attract more purchasers in smaller organisations if it was reduced."
"The price of this product is too high."
