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."
"The features of Microsoft Sentinel that I appreciate the most include the app integration."
"Sentinel uses Azure Logic Apps for automation, which is really powerful. This allows us to easily automate responses to incidents."
"The machine learning and artificial intelligence on offer are great."
"It's easy to use. It's a very good product. It can easily ingest data from anywhere. It has an easily understandable language to perform actions."
"The integration between them is good and straightforward, the documentation is excellent, and we do not have any problems."
"Sentinel's cost-effectiveness blows a lot of other solutions out of the water, especially if you're already in Azure and you can leverage some relationships to bring that cost down."
"The main benefit is the ease of integration."
"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."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"The built-in SOAR is not really good out-of-the-box. The SOAR relies on logic apps and you almost need to have some kind of developer background to be able to make these logic apps. Most security people cannot develop anything..."
"Our SIEM is only as good as the information we are ingesting. We are all human and we forget to ingest things."
"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."
"With one of my clients, we deployed the solution. We estimated that the ingestion would be up to this particular mark, but that ingestion somehow got way beyond that. Within a month to a month and a half, they got charged 35,000 CAD, which was a huge turn off for us."
"Technical support doesn't understand the features well enough. Their solutions and response time aren't very good."
"The interface could be more user-friendly."
"The solution should allow for a streamlined CI/CD procedure."
"In terms of improvements, pricing, licensing, and overall cost could be better."
 

Pricing and Cost Advice

"I rate the tool's pricing a one out of ten."
"Sentinel is fairly priced and pretty cost-effective."
"The pay-as-you-go model is beneficial to customers."
"In comparison to other security solutions, Microsoft Sentinel offers a reasonable price for the features included."
"I am just paying for the log space with Azure Sentinel. It costs us about $2,000 a month. Most of the logs are free. We are only paying money for Azure Firewall logs because email logs or Azure AD logs are free to use for us."
"Cost-wise, Sentinel is based on the volume of information being ingested, so it can be quite pricey. The ability to use strategies to control what data is being ingested is important."
"Microsoft Sentinel is pretty expensive, and they recently announced that they will increase the price of all Microsoft services running in Azure by 11 percent. Luckily, I'm not responsible for the financial side. For one of my clients, the estimated cost is 880,000 euros for one year. There are additional costs for the service agreement."
"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."
"From a cost point of view, it is not a cheap product. It's, like, an enterprise-level application. So if you compare it with a low-level application, it's expensive, but if you compare it with the same-level application, it's pretty much cost-effective, I think."
