Improved incident monitoring has reduced false positives and supports audit-ready reporting
The best features Sentinel offers, in my experience, include the filtering features and the ability to run KQL queries so that I can understand what table has what and when the last log has been monitored and reported. Sentinel has positively impacted my organization by improving monitoring significantly. As a pay-as-you-go service, we are ingesting logs as needed. When the pay-as-you-go service is enabled, we can either ingest whenever there is a spike in the logs, and when there are fewer logs, we can reduce the ingestion. This approach is helpful for both the organization and me. In terms of metrics showing how Sentinel has helped, as part of log filtering, we have reduced around thirty to thirty-five percent of false-positive incident creation. We have also cleared some audits by enabling log retention in Sentinel, allowing us to pull out data for audits when necessary using both hot retention and cold retention. This has helped the organization as a whole.

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

"It provides real time security event analytics."
"The stability is phenomenal and we never had any issues with downtime or even had to restart."
"We can do advanced hunting queries and modify SQL queries to get desired results based on the rules triggering over the console."
"Sentinel has positively impacted my organization by improving monitoring significantly."
"It makes everything easier by automating some tasks and growing with our needs."
"If Sentinel is integrated with Identity Manager and User Application Portal, the solution runs simply perfect!"
"The tool is simple to use."
"Sentinel is a tool that, if it's well configured, removes from view all unnecessary information and shows you only needful entries, so you can do your job faster, more conveniently, and with high performance."
"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

"There are still a few vendor-specific devices for which Sentinel needs to work on integration, such as Netskope devices."
"The web interface needs to be improved, as it has a java-based way to call its controls."
"Documentation for security aspects could be improved. It is difficult to find clear information about encryption or risks that are addressed."
"The solution does not allow outsourced authorizations."
"On version 5, builder was somewhat unstable during deployment -> workaround strong procedure with too many middle steps of saves."
"It's probably not a product that I would recommend to anyone."
"Creating a drag-and-drop dashboard or workbook in Sentinel is a little more complex compared to other tools like LogRhythm and IBM QRadar."
"This product's connection to certain types of cloud systems could be improved. We can do Microsoft, Google, and Amazon, but there are a lot of other things happening in the cloud that we do not connect well enough to. This product could be improved with better connection to cloud-based solutions."
"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."
 

Pricing and Cost Advice

"We inquired about getting support from the vendor, Micro Focus, but the cost was very high."
"We receive a pricing discount because of our ongoing partnership with Micro Focus."
"Sentinel's slightly on the expensive side."
"Sentinel is a subscription-based solution."
"Sentinel is moderately priced."
"The solution’s pricing is aligned with its competitors."
"It’s a single license platform."
