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.

Micro segmentation has strengthened zero trust security and isolates production from test environments
The advantages of VMware NSX include its micro-segmentation for internal security at the firewall and VM levels, which is very powerful and helps us comply with complete Zero Trust security models. We are able to achieve this and configure network level virtualization with no dependency on VLANs. Micro-segmentation helps improve our security significantly. We are not totally dependent upon our physical upfront firewall, and it makes sense to configure everything using VMware NSX, leading to multiple improvements in our organization. We moved from traditional networking such as VLANs from the firewall and switches to VMware NSX segmentation. We achieve one firewall per VLAN and can stop lateral movement such as ransomware control. The Zero Trust model is the main functionality and architecture it offers, allowing application isolation, such as having a separate production and test environment. Consistent networking and security policies across different environments have a major and very positive impact on our business operations, allowing us to achieve the security posture we want with compliance and regulations.

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 is the integration with the firewall."
"What makes them unique is their range of discovery, the way they can effectively mimic actual PC or smartphone endpoints to examine malware behavior."
"Some of the key features I find most valuable are the highly graphical user interface, virtualization of networks, and Microsoft application compatibility. It has all the functionality that we require."
"I value the ability to dynamically configure our network on the fly using VMware NSX."
"This product is better for network security than Cisco ASA and Firepower."
"We have many advantages with the cloud infrastructure."
"It does have capabilities of micro-segmenting a network, being able to create smaller segments of various types of applications separated by various tiers."
"The solution is very stable and reliable."
 

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."
"We would to have a reverse proxy. This would add great value to the solution."
"I have concerns on the stability of VMware NSX, because it breaks multiple times in customer environments, especially when you scale it across a big data center."
"They could do more with cloud management."
"There were some issues with finance and other accounting."
"The price is expensive and it could attract more purchasers in smaller organisations if it was reduced."
"The response time of the technical support team could improve. We also sometimes had the feeling that they didn't properly understand the issue."
"The reporting functionality could be better, and there could be an easier way of forwarding events. There's room for improvement in the product."
"They need to enhance their technical support. There is no comparison between VMware technical support and Cisco's technical support."
 

Pricing and Cost Advice

"It’s a single license platform."
"I was not involved in the purchase of the solution but I hear it is on the expensive side."
"The price is pretty high."
"I would rate the pricing of VMware NSX as seven out of ten"
"The product pricing ranges from medium to expensive. I rate the pricing a seven out of ten."
"The implementation of VMware NSX can be cost-intensive, especially if an organization is looking for a comprehensive solution. The costs can vary based on factors like the level of conversation and discounts obtained during negotiations. Some government organizations, for instance, may find the prices relatively high, leading to concerns about budget hikes, especially when deploying the solution across the entire organization. Regarding maintenance and support, they are typically included in the standard licensing costs for enterprise-level businesses. While these costs can be significant, many companies opt for standard licensing to ensure they have access to necessary support and maintenance services."
"We are using the free version of the solution."
"VMware NSX isn't cheap."
"If five is a good price and one is a high price, I would rate the price a one out of five."
