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.

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.

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."
"Novell SIEM was my second technology of this kind."
"The most valuable feature of this solution is that it provides a central locking system for many event sources."
"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."
"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 gave us logs to tell us what's going right and wrong in your environment so we could secure the network."
"It makes everything easier by automating some tasks and growing with our needs."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"You need a lot of Unix scripting knowledge in order to manage the tool, which is one of the main issues that we faced."
"The solution does not allow outsourced authorizations."
"Frankly speaking, we did not find this product to be valuable, at all."
"Price is always a consideration, so the price would be nice if it were lower."
"The dashboard and customer view should be improved."
"I would like to see a better reporting work structure on the dashboard."
"There are still a few vendor-specific devices for which Sentinel needs to work on integration, such as Netskope devices."
"Documentation for security aspects could be improved. It is difficult to find clear information about encryption or risks that are addressed."
 

Pricing and Cost Advice

"I rate the tool's pricing a one out of ten."
"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 is moderately priced."
"Sentinel is a subscription-based solution."
"Sentinel's slightly on the expensive side."
"The solution’s pricing is aligned with its competitors."
