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."
"The best feature of Microsoft Sentinel is its ability to unify all dashboards or functions into one modern SecOps dashboard."
"The SOAR playbooks are Sentinel's most valuable feature. It gives you a unified toolset for detecting, investigating, and responding to incidents. That's what clearly differentiates Sentinels from its competitors. It's cloud-native, offering end-to-end coverage with more than 120 connectors. All types of data logs can be poured into the system so analysis can happen. That end-to-end visibility gives it the advantage."
"The product is extremely cost-effective and affordable for customers."
"The automation feature is valuable."
"Microsoft is continuously improving this product, and we also have private access where we can see what features are being launched and provide input to them."
"Overall, per week, Sentinel saves us 40 to 45 hours, per person."
"Microsoft Sentinel has made it easier for us to sell SOC-as-a-Service to, more or less, any customer and not just the big ones."
"Sentinel lets us investigate threats and comprehensively respond from one console."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"We do see continuous improvement all the time, however, I haven't got a specific feature that is lacking or not well designed."
"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."
"It would be nice to be able to leverage more AI to handle more data and recovery aspects in the future."
"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."
"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."
"There is room for improvement in terms of integrations."
"There is room for improvement in terms of integrations. We have some tools, such as our off-site Meraki firewalls, that have not fully integrated with Sentinel. We lack integration for Syslogs into Sentinel."
"Add more out-of-the-box connectors with other SaaS platforms/applications."
 

Pricing and Cost Advice

"I rate the tool's pricing a one out of ten."
"The pricing is reasonable, and we think Sentinel is worth what we pay for it."
"It is priced fairly given the value that you get from the use of the product. The biggest mistake people make with Microsoft Sentinel is not understanding the pricing model and the amount of data that they are going to be running through the tool because you are paying based on the flow. You are paying based on the amount of data that is moving through the tool. People do not plan, and therefore, they get surprised by the cost associated with using the tool. They connect everything because they want to know everything, but connecting everything is very expensive."
"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 product is costly compared to Splunk."
"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."
"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."
"In comparison to other security solutions, Microsoft Sentinel offers a reasonable price for the features included."
"We are charged based on the amount of data used, which can become expensive."
