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."
"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."
"The machine learning and artificial intelligence on offer are great."
"We have no complaints about the features or functionality."
"In Azure Sentinel, we have found, they do have a store in their capability. AI and intelligence features. We found that to be very helpful for us because some other things we do need to integrate again or find another vendor for the store"
"One of the most valuable features is that it creates a kind of a single pane of glass for organizations that already use Microsoft software. So, when they have things like Microsoft 365, it is very easy for them to kind of plug in or enroll those endpoints into the Azure Sentinel service."
"The best feature is that onboarding to the SIM solution is quite easy. If you are using cloud-based solutions, it's just a few clicks to migrate it."
"We have no complaints about the features or functionality."
"Using Microsoft Sentinel has reduced the time spent per incident from three hours to one and a half to two hours."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"Depending on when Microsoft releases the updates, it can be challenging, but they usually notify us ahead of time."
"Currently, the watchlist feature is being utilized, and although there have been improvements, it is still not fully optimized."
"The three challenges we have are outside of the Microsoft ecosystem. In New Zealand, there are customers that run dual stack, running Microsoft but also competitor products, EDR software, cloud security software, and other tooling."
"Its documentation is not so simple. It is easy for somebody who is Microsoft certified or more closely attached to Microsoft solutions."
"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."
"The solution could improve the playbooks."
"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."
"If I can use Sentinel offline at home and use it on a local network, it would be great."
 

Pricing and Cost Advice

"I rate the tool's pricing a one out of ten."
"It comes with a Microsoft subscription which the customer has, so they don't have to invest somewhere else."
"I have worked with a lot of SIEMs. We are using Sentinel three to four times more than other SIEMs that we have used. Azure Sentinel's only limitation is its price point. Sentinel costs a lot if your ingestion goes up to a certain point."
"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."
"The solution is expensive and there is a daily usage fee."
"Pricing is pay-as-you-go with Sentinel, which is good because it all depends on the number of users and the number of devices to which you connect."
"From a cost perspective, there are some additional charges in addition to the licensing."
"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."
"Sentinel is fairly priced and pretty cost-effective."
