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

"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"The ability to scale from different clouds. At the moment, the scalability of the product is the number one thing that I saw."
"It is easy to implement it."
"The security offered by VMware NSX is the most valuable, plus it's a feature-rich product that's straightforward to install and configure."
"We are happy with the scalability."
"The most valuable feature of VMware NSX is the load balancing and routing of firewall rules. Many of the features are beneficial."
"I value the ability to dynamically configure our network on the fly using VMware NSX."
"Provides protection for virtual machines."
"The microsegmentation is a good feature. You can segment details, products, or hardware information."
 

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."
"I would like to see automation capabilities in the deployment process."
"A faster resolution time would be beneficial."
"It's not feature-rich."
"This solution is really unusable from my perspective at this point. Overall, I would rate the solution a one of ten."
"A room for improvement in VMware NSX is that it has some security vulnerabilities, which means my company has to apply the patches every once in a while."
"The training costs a minimum of $3,000, which is expensive and should be reduced."
"Going through and getting more features sets from the routing protocols is definitely necessary for the future."
"The next release of NSX should try to make Kubernetes and container integration a little easier than it is now. It's quite a complicated process."
 

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."
"VMware NSX is expensive and everything is licensed. We have to pay for each individual feature."
"There is a license required for this solution, we pay annually."
"The price is pretty high."
"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."
"We are using a perpetual license to use the solution and we have support."
