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 makes everything easier by automating some tasks and growing with our needs."
"Transactional user information improves security, prevents fraud, and promotes best practices."
"The most valuable feature of this solution is that it provides a central locking system for many event sources."
"The native integration with out-of-the box format is hassle free and allows data to be used advantageously."
"The solution lets us get all the logs properly and regularly monitor customer infrastructure."
"Sentinel has positively impacted my organization by improving monitoring significantly."
"The stability is phenomenal and we never had any issues with downtime or even had to restart."
"One of the most valuable features is the business intelligence engine. It's very important because it keeps track of everything that's happening and alerts us if something is different than expected. The first time I used it, I was shocked at how well it performed. Another valuable feature that I think makes this product worth the price you pay for it is that it connects to basically every system that provides some form of logging, and it's very easy to set up what triggers this."
"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 is no integration in the web-side of the tool."
"I would prefer to extend dashboards part and their functions in Web GUI version, so the charts could be for configurable."
"There is a need for more flexibility in customization, especially when working with different vendors and platforms."
"Documentation for security aspects could be improved. It is difficult to find clear information about encryption or risks that are addressed."
"There are still a few vendor-specific devices for which Sentinel needs to work on integration, such as Netskope devices."
"On version 5, builder was somewhat unstable during deployment -> workaround strong procedure with too many middle steps of saves."
"The dashboard and customer view should be improved."
"Some functions look great but, in practice, some key limitations turn the process into something opaque."
"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

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