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.

Centralized monitoring has improved threat response but cost control still needs refinement
Based on real operations used in our corporate IT environment, the key features include log correlation and incident view. Microsoft Sentinel's biggest strength is how it correlates multiple related alerts into a single incident. This significantly reduces alert noise and helps the SOC focus on real threats instead of isolated events. Another valuable feature is KQL-based threat hunting with Kusto Query Language. The flexibility of this language allows us to build custom hunting queries based on our environment's behavior. This is extremely useful for detecting low and slow threats or hidden threats that default rules may miss. Cloud-native scalability and stability is another important feature. Being cloud-native, Microsoft Sentinel scales well for medium to large corporate environments without infrastructure management. Stability has been solid in day-to-day production. SOAR automation using playbooks is a feature we highly recommend. Microsoft Sentinel's SOAR functionality helps automate repetitive SOC tasks like alert enrichment and notification. This saves analyst time and improves response consistency.

Quotes from Members

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

Pros

"The tool aggregates logs. We can see the logs in one place."
"We use the solution to collect logs."
"The analytics has a lot of advantages because there are 300 default use cases for rules and we can modify them per our environment. We can create other rules as well. Analytics is a useful feature."
"The biggest feature we've got out of it is visibility into our environment and what's going on across our estate."
"For the people who are on the cloud, I would suggest they go for Sentinel regardless of any other SIEM, as it will do a good integration with other solutions and with other cloud providers while providing a holistic view as well."
"Having your logs put all in one place with machine learning working on those logs is a good feature."
"If you know how to do KQL (kusto query language) queries, which are how you query the log data inside Sentinel, the information is pretty rich. You can get down to a good level of detail regarding event information or notifications."
"By implementing the SIEM along with Security Center, we have improved security to a mature level, and we are able to meet the compliance reporting and client requirements for security within the organization."
"For those who want to adopt Sentinel, I'd advise that it's a really one-stop solution for all the security needs."
"Sentinel has reduced the work involved in the event investigation by quite a lot."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"I would like to be able to monitor applications outside of the Azure Cloud."
"Some of the data connectors are outdated, at least the ones that utilize Linux machines for log forwarding."
"The SOC optimization feature of Microsoft Sentinel does not appear applicable at the moment in terms of data management and cost efficiency."
"Although the integrations are good, it can sometimes be information overload."
"We do see continuous improvement all the time, however, I haven't got a specific feature that is lacking or not well designed."
"There is some relatively advanced knowledge that you have to have to properly leverage Sentinel's full capabilities."
"One key area that can be improved is by building a strong integration with our XDR platform."
"Azure Sentinel is very costly, or at least it appears to be very costly."
 

Pricing and Cost Advice

"I rate the tool's pricing a one out of ten."
"Good monthly operational cost model for the detection and response outcomes delivered, M365 logs don't count toward the limits which is a good benefit."
"No license is required to make use of Sentinel, but you need to buy products to get the data. In general, the price of those products is comparable to similar products."
"Microsoft Sentinel can be costly, particularly for data management."
"Microsoft Sentinel's pricing is relatively expensive and extremely confusing."
"Azure Sentinel is very costly, or at least it appears to be very costly. The costs vary based on your ingestion and your retention charges."
"Some of the licensing models can be a little bit difficult to understand and confusing at times, but overall it's a reasonable licensing model compared to some other SIEMs that charge you a lot per data."
"I am not involved on the financial side, but from an enterprise-wide use perspective, I think the price is good enough."
"The current licensing is based on the logs that are being ingested on the platform. Most of the SIEM solutions utilize that pricing model, but Microsoft should give us a customization option for controlling the kind of logs that we feed into Microsoft Sentinel. That will be much better. Otherwise, the pricing is a bit higher."
