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.

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."
"The stability is phenomenal and we never had any issues with downtime or even had to restart."
"If Sentinel is integrated with Identity Manager and User Application Portal, the solution runs simply perfect!"
"The correlation engine allows our clients to generate rules more efficiently."
"Sentinel has positively impacted my organization by improving monitoring significantly."
"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."
"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."
"It provides real time security event analytics."
"The solution's Kusto Query Language (KQL) execution time is pretty good."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"I rate Sentinel a six out of ten for scalability."
"It's probably not a product that I would recommend to anyone."
"Documentation for security aspects could be improved. It is difficult to find clear information about encryption or risks that are addressed."
"Some functions look great but, in practice, some key limitations turn the process into something opaque."
"I would prefer to extend dashboards part and their functions in Web GUI version, so the charts could be for configurable."
"There are still a few vendor-specific devices for which Sentinel needs to work on integration, such as Netskope devices."
"It is an ancient product."
"On version 5, builder was somewhat unstable during deployment -> workaround strong procedure with too many middle steps of saves."
 

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."
"The solution’s pricing is aligned with its competitors."
"Sentinel is moderately priced."
"Sentinel's slightly on the expensive side."
"Sentinel is a subscription-based solution."
