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 features are security and dynamic routing."
"The interface is intuitive enough."
"The Distributed firewall is simple to add to the network and rules are easy to implement."
"The alert features are the most valuable."
"The most valuable features are the micro-segmentation and integrated security options."
"It's what we use the CIS Benchmarks for. It's for employing hardening rules and keeping them up to date when things happen on our systems. So it's really configurations and stuff that harden and report back."
"I am impressed with the tool's protection."
"Overall, for me, it's a good solution and has been working well."
 

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."
"It lacks full knowledge of physical side of the network topology."
"The integration with other brands is not the best."
"This solution is really unusable from my perspective at this point. Overall, I would rate the solution a one of ten."
"There is room for improvement in VMware NSX's workload management, particularly in the orchestration layer and in managing workloads across multiple clouds."
"Going through and getting more features sets from the routing protocols is definitely necessary for the future."
"There could be an improvement in regards to security."
"The support from VMware NSX could improve."
"Nowadays, NSX supports the KVM and ESXi hypervisors only. It should also support Hyper-V and Citrix hypervisors."
 

Pricing and Cost Advice

"It’s a single license platform."
"The licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price."
"The tool's pricing is reasonable."
"The price is significantly high and it can be a hurdle for many potential users."
"I would rate the pricing of VMware NSX as seven out of ten"
"The licensing fees are expensive and we pay on a yearly basis."
"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 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."
"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."
