Simple antivirus solution integrates well but could improve pricing and currency options
I don't really have experience working with these solutions. I promote them for our clients, but I don't work with them. I can't share my experience with these tools as I make assumptions about that. For both Adlumin and CrowdStrike, both confirm that they're scalable and enterprise-ready and all those kinds of things. We haven't had any specific problem with either of those. We just have a preference for which one we would prefer. If somebody says they want to use a different one from the one that we prefer, then we have to find reasons why they aren't. But scalability is not one of the reasons that one is better over the other. I don't really have advice for people that are looking into using Sentinel; just do your research across what is available. On a scale of one to ten, I rate Sentinel a seven.

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

"In my opinion, Sentinel's best features include that it's a very easy product to use, it's very simple, and the after-sale service is very good."
"The native integration with out-of-the box format is hassle free and allows data to be used advantageously."
"The most valuable feature is the flexible log for identifying security threats inside an application. Sentinel is very good at this."
"We can do advanced hunting queries and modify SQL queries to get desired results based on the rules triggering over the console."
"The solution lets us get all the logs properly and regularly monitor customer infrastructure."
"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."
"The solution's Kusto Query Language (KQL) execution time is pretty good."
"Sentinel gave us logs to tell us what's going right and wrong in your environment so we could secure the network."
"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."
"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."
"Creating a drag-and-drop dashboard or workbook in Sentinel is a little more complex compared to other tools like LogRhythm and IBM QRadar."
"The dashboard and customer view should be improved"
"It is an ancient product."
"I rate Sentinel a six out of ten for scalability."
"There is a need for more flexibility in customization, especially when working with different vendors and platforms."
"Price is always a consideration, so the price would be nice if it were lower."
"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."
"The solution’s pricing is aligned with its competitors."
"Sentinel's slightly on the expensive side."
"Sentinel is moderately priced."
"Sentinel is a subscription-based solution."
"We receive a pricing discount because of our ongoing partnership with Micro Focus."
"It’s a single license platform."
