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 most valuable feature of VMware NSX is the ease of use and its user friendly. For example, it is simple to change the subnet masks."
"The most valuable feature is the ability to create, develop, and deploy servers in minutes to hours, rather than days."
"From a distributed firewall perspective, it's a solid solution."
"One of the big improvements between the NSX-V and NSX-T is that in NSX-T you are no longer dependent on V-Center anymore."
"I rate the scalability as ten out of ten."
"The most powerful feature of VMware NSX is the micro-segmentation that allows us to separate the different protocols our application works with."
"NSX can reduce costs and has good service. It is easy for you and your users to use."
"The installation is straightforward, it took a couple of hours."
 

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."
"VMware NSX only supports some platforms like KVM."
"Their licensing model should make it easier to purchase licenses."
"I have no complaints regarding the user interface or any technical issues."
"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."
"We had some complexities implementing into the other parts of a network."
"It takes time to do the initial setup. It is a bit slow, which is surprising."
"If there are other solutions already in place, it can be difficult to implement."
"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 solution is very expensive."
"All the institutions have to pay monthly for the services in the cloud. They have to pay $30,000 every month for this service every three years."
"If five is a good price and one is a high price, I would rate the price a one out of five."
"VMware has always been geared towards enterprise and their pricing options are a bit high. Their price is higher than other options in the market."
"We can't go without NSX, so it's invaluable from this perspective."
"VMware NSX is expensive and everything is licensed. We have to pay for each individual feature."
"I was not involved in the purchase of the solution but I hear it is on the expensive side."
"The licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price."
