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."
"Microsoft Sentinel is an awesome SIEM/SOAR tool for customers with active Cloud presence."
"Microsoft Sentinel's ability to correlate data from multiple sources has improved our capability significantly."
"The features that stand out are the detection engine and its integration with multiple data sources."
"For those who want to adopt Sentinel, I'd advise that it's a really one-stop solution for all the security needs."
"Sentinel is a Microsoft product, so they provide very robust use cases and analytic groups, which are very beneficial for the security team. I also like the ability to integrate data sources into the software for on-premise and cloud-based solutions."
"The main benefit is that as companies migrate their systems and services into the Cloud, especially if they're migrating into Azure, they've got a native SIEM available to them immediately."
"It's a great product."
"It has a lot of great features."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"However, we are not using it for some features, mainly for cost-related reasons and our company policy."
"The KQL query does not function effectively with Windows 11 machines, and in the majority of machine-based investigations, KQL queries are essential for organizing the data during investigations."
"Its documentation is not so simple. It is easy for somebody who is Microsoft certified or more closely attached to Microsoft solutions. It is not easy for those who are working on open-source platforms. There isn't a central point where everything is documented, and there is no specific training or certification."
"I think a lot of customers don't fully understand the full capabilities of Azure Sentinel yet."
"Multi-tenancy, in my opinion, needs to be improved. I believe it can do better as a managed service provider."
"The reporting could be more structured."
"If their UI was a bit more streamlined and easy to find when I need it, then that would be a great improvement."
"Microsoft Sentinel's ability to correlate data from multiple sources does not enhance our threat detection capabilities beyond what a simple data lake solution could offer, as we are a developer, so it is not necessarily applicable."
 

Pricing and Cost Advice

"I rate the tool's pricing a one out of ten."
"The pricing is fair... With a traditional SIEM, you pay a lump sum for licenses. But with Sentinel, it's pay-as-you-go according to the amount of data you inject."
"The price is reasonable because Sentinel includes features like user behavior analytics and SOAR that are typically sold separately. Overall, a standalone on-prem solution would require some high-end servers, and there's a different cost. It is a cloud-based solution, so there are backend cloud computing costs, but they are negligible."
"It varies on a case-by-case basis. It is about $2,000 per month. The cost is very low in comparison to other SIEMs if you are already a Microsoft customer. If you are using the complete Microsoft stack, the cost reduces by almost 42% to 50%. Its cost depends on the number of logs and the type of subscription you have. You need to have an Azure subscription, and there are charges for log ingestion, and there are charges for the connectors."
"The pricing is reasonable, and we think Sentinel is worth what we pay for it."
"The solution is expensive and there is a daily usage fee."
"The pay-as-you-go model is beneficial to customers."
"Microsoft Sentinel can be costly, particularly for data management."
"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."
