Tony Zafiropoulos - PeerSpot reviewer
Aggregates logs in one place and helps to review data points
We tried Graylog Security, starting with their inexpensive open-source version. We tested it out and continued using it for a while. As for the main differences between Graylog Security and other vendors, some users might prefer cloud-based platforms over on-premises solutions. It isn't inherently cloud-native, but that might not matter much for some.
Simon Johnston - PeerSpot reviewer
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.

Quotes from Members

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

Pros

"We use the solution to collect logs."
"The tool aggregates logs. We can see the logs in one place."
"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 most valuable feature is the flexible log for identifying security threats inside an application. Sentinel is very good at this."
"The solution lets us get all the logs properly and regularly monitor customer infrastructure."
"The most valuable feature of this solution is that it provides a central locking system for many event sources."
"The tool is simple to use."
"The native integration with out-of-the box format is hassle free and allows data to be used advantageously."
"It makes everything easier by automating some tasks and growing with our needs."

Cons

"Graylog Security needs to incorporate security scorecards."
"The dashboard and customer view should be improved"
"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."
"Price is always a consideration, so the price would be nice if it were lower."
"Creating a drag-and-drop dashboard or workbook in Sentinel is a little more complex compared to other tools like LogRhythm and IBM QRadar."
"There is a need for more flexibility in customization, especially when working with different vendors and platforms."
"There are still a few vendor-specific devices for which Sentinel needs to work on integration, such as Netskope devices."
"The solution does not allow outsourced authorizations."
"I rate Sentinel a six out of ten for scalability."
 

Pricing and Cost Advice

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