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."
"It's a beneficial tool."
"The microsegmentation is a good feature, and you can segment details, products, or hardware information."
"It works and it is powerful in terms of governance, telemetry, ease of use, and ease of deployment."
"The product has valuable features for security and network extension."
"The initial setup was straightforward. You just have to click it and follow the manuals."
"The most powerful feature of VMware NSX is the micro-segmentation that allows us to separate the different protocols our application works with."
"Firewall security is one of VMware NSX's vital features"
"The most valuable features for us at this early stage are the interface and the integration with existing VMware solutions."
 

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 scalability is not perfect."
"Traffic flow introspection topology visibility is definitely needed because at the moment, NSX-T lacks in this area."
"Tech support is nice. It could be a little bit better."
"Going through and getting more features sets from the routing protocols is definitely necessary for the future."
"There are sometimes mismatch in the control, the details and what you actually see on the transport note."
"The first time setting it up was difficult."
"They need to enhance their technical support. There is no comparison between VMware technical support and Cisco's technical support."
"If an organization is not able to use NSX to its full potential (Switching, Routing, Load-balancing, Firewall, IDS, IPS etc.) then its not worth it."
 

Pricing and Cost Advice

"It’s a single license platform."
"The subscription is on a yearly basis."
"There is a license required for this solution and there is also a support license available. The price of the solution could be better."
"You can scale NSX if you have the resources, but it's usually expensive and complex to scale up."
"The solution is reasonable at the local level."
"I was not involved in the purchase of the solution but I hear it is on the expensive side."
"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."
"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."
