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."
"Native integration with Microsoft security products or other Microsoft software is also crucial. For example, we can integrate Sentinel with Office 365 with one click. Other integrations aren't as easy. Sometimes, we have to do it manually."
"Having your logs put all in one place with machine learning working on those logs is a good feature."
"The log analysis is excellent; it can predict what can or will happen regarding use patterns and vulnerabilities."
"I've worked on most of the top SIEM solutions, and Sentinel has an edge in most areas. For example, it has built-in SOAR capabilities, allowing you to run playbooks automatically. Other vendors typically offer SOAR as a separate licensed solution or module, but you get it free with Sentinel. In-depth incident integration is available out of the box."
"Microsoft Sentinel saves us time; it has provided us with a very rich automation solution, and we don't need to log in and check for different things, so it saves a lot of time for associates, about 30 to 40 minutes on average per incident."
"Sentinel improved how we investigate incidents. We can create watchlists and update them to align with the latest threat intelligence. The information Microsoft provides enables us to understand thoroughly and improve as we go along. It allows us to provide monthly reports to our clients on their security posture."
"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."
"The product is extremely cost-effective and affordable for customers."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"Microsoft Sentinel should continue adding support for several other security brands because sometimes you have a firewall from a different brand and if you cannot correlate or integrate that seamlessly, it creates multiple points of checking information, which diminishes efficiency."
"Microsoft Defender has a built-in threat expert option that enables you to contact an expert. That feature isn't available in Sentinel because it's a huge product that integrates all the technologies. I would like Microsoft to add the threat expert option so we can contact them. There are a few other features, like threat assessment that the PG team is working on. I expect them to release this feature in the next quarter."
"In terms of improvements, pricing, licensing, and overall cost could be better."
"There is some relatively advanced knowledge that you have to have to properly leverage Sentinel's full capabilities. I'm thinking about things like the creation of workbooks, how you do threat-hunting, and the kinds of notifications you're getting... It takes time for people to ramp up on that and develop a familiarity or expertise with it."
"Sentinel still has some anomalies. For example, sometimes when we write a query for log analysis with KQL, it doesn't give us the data in a proper way... Also, the fields or columns could be improved. Sometimes, it is not giving the desired results and there is a blank field."
"They could use some kind of workbook. There is some limitation doing the editing and creating the workbook."
"Sentinel provides decent visibility, but it's sometimes a little cumbersome to get to the information I want because there is so much information. I would also like to see more seamless integration between Sentinel and third-party security products."
"There is room for improvement in entity behavior and the integration site."
 

Pricing and Cost Advice

"I rate the tool's pricing a one out of ten."
"We are charged based on the amount of data used, which can become expensive."
"Sentinel can be expensive. When you ingest data from sources that are outside of the cloud, you're paying a fair amount for that data ingestion. When you're ingesting data sources from within the cloud, depending on what your retention periods are, it's not that expensive."
"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."
"Microsoft Sentinel requires an E5 license."
"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."
"The are two native advantages for customers that use M365 Security and Sentinel. The first advantage is that the log or security-event ingestion into Sentinel is free. Cost-wise, they're saving a lot and that is a major advantage."
"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."
"The product is costly compared to Splunk."
