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

"We use the solution to collect logs."
"The tool aggregates logs. We can see the logs in one place."
"It is always correlating to IOCs for normal attacks, using Azure-related resources. For example, if any illegitimate IP starts unusual activity on our Azure firewall, then it automatically generates an alarm for us."
"Microsoft Sentinel's ability to correlate data from multiple sources has enhanced my threat detection capabilities beyond what simple data lake solutions offer."
"The query language of Microsoft Sentinel is easy to understand and use."
"Microsoft Sentinel's ability to correlate data from multiple sources has improved our capability significantly."
"Azure Application Gateway makes things a lot easier. You can create dashboards, alert rules, hunting and custom queries, and functions with it."
"Microsoft Sentinel stands out mainly for its signal-to-noise reduction; LogRhythm required numerous AI rules to reach a similar level of noise reduction."
"Sentinel uses Azure Logic Apps for automation, which is really powerful. This allows us to easily automate responses to incidents."
"Log aggregation and data connectors are the most valuable features."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"With non-Microsoft products, there are definitely integration issues. Exporting the logs is very difficult, and the API calls are not being generated frequently from the Microsoft end."
"I think the number one area of improvement for Sentinel would be the cost."
"The reporting could be more structured."
"The AI capabilities must be improved."
"In terms of features I would like to see in future releases, I'm interested in a few more use cases around automation. I do believe a lot of automation is available, and more is in progress, but that would be my area of interest."
"The performance could be improved. If I create 15 to 20 lines for a single-use case in KQL, sometimes it takes more time to execute. If I create use cases within a certain timeline, the result will show in .01 seconds. A complex query takes more time to get results."
"From a client perspective, they'd like to see more cost savings."
"The integration challenges arise from both sides; Google tends to be noisy, and we find only ten analytic rules out of the box, necessitating the use of Defender for Cloud for alerts, which indicates a need for better documentation during deployment."
 

Pricing and Cost Advice

"I rate the tool's pricing a one out of ten."
"Microsoft is costlier. Some organizations may not be able to afford the cost of Sentinel orchestration and the Log Analytics workspace. The transaction hosting cost is also a little bit on the high side, compared to AWS and GCP."
"I have had mixed feedback. At one point, I heard a client say that it sometimes seems more expensive. Most of the clients are on Office 365 or M365, and they are forced to take Azure SIEM because of the integration."
"Pricing for Microsoft Sentinel could always be lower, but it's workable. The ingestion costs for the data analytics is usually the highest cost, but the licensing per Microsoft Sentinel is fairly straightforward and transparent."
"Sentinel's price is comparable to pretty much everything out there. None of it is cheap, but we didn't think we could save money by going a different route. Sentinel was part of our Azure expenditures, so it was easier to add the expense instead of having a completely separate vendor."
"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."
"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 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."
"I am not involved on the financial side, but from an enterprise-wide use perspective, I think the price is good enough."
