Provides a memory utilization graph and shows disk space and uplink utilization but could include smart navigation in next release
The solution is deployed on-premises. There are more than 20 people who use this solution in my organization. They're infrastructure engineers, network engineers, and information security engineers A great feature is the memory utilization graph. It shows utilization, disk space utilization,…

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"A great feature is the memory utilization graph."
"The feature that I have found the most useful is the decode of packets. It gives us a variety of information that helps us in figuring out what to look at. The networks are getting really complex, and without the information that we get from Iris Session Analyzer, we couldn't do our job. Its graphical user interface is also very easy to use and intuitive."
"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."
 

Cons

"They can increase flexibility in the search engine. Basically, I go with the information I have at the time. If I could just type in the parameter that I want to search for and its value, it might be easier than having to do the groundwork upfront before I can get my traces."
"Sometimes the network analyzer will show that a server is down when it's actually working."
"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."
 

Pricing and Cost Advice

"I don't know what the cost to buy the solution was, but I doubt if it's a significant part of the budget as far as the maintenance and support are concerned."
"It’s a single license platform."
