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 analytic rule is the most valuable feature."
"The product can integrate with any device."
"It is quite efficient. It helps our clients in identifying their security issues and respond quickly. Our clients want to automate incident response and all those things."
"Microsoft Sentinel flags when admin credentials log in from an unusual location, automatically alerting the security team so they can investigate."
"Microsoft Sentinel is a cloud-native SIEM solution, so it helped us reduce our infrastructure costs and deliver better services to our customers."
"I like the unified security console. You can close incidents using Sentinel in all other Microsoft Security portals, when it comes to incident response."
"Microsoft Sentinel has helped by streamlining our security. We have a nine-member network team, with three members managing security for the city, and Sentinel allows us to operate an unofficial SOC."
"We are able to deploy within half an hour and we only require one person to complete the implementation."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"Everyone has their favorites. There is always room for improvement, and everybody will say, "I wish you could do this for me or that for me." It is a personal thing based on how you use the tool. I do not necessarily have those thoughts, and they are probably not really valuable because they are unique to the context of the user, but broadly, where it can continue to improve is by adding more connectors to more systems."
"One key area that can be improved is by building a strong integration with our XDR platform."
"Microsoft Sentinel could be improved by making the UI more intuitive, simplifying KQL queries for easier use, improving cost visibility and optimization controls, and enhancing performance and query speed when handling large volumes of data."
"The SOC optimization feature of Microsoft Sentinel does not appear applicable at the moment in terms of data management and cost efficiency."
"If I see an alert and I want to drill down and get more details about the alert, it's not just one click. In other SIEM tools, you just have to click the IP address of the entity and they give you the complete picture. In Sentinel, you have to write queries or use saved queries to get details."
"They can work on the EDR side of things... Every time we need to onboard these kinds of machines into the EDR, we need to do it with the help of Intune, to sync up the devices, and do the configuration. I'm looking for something on the EDR side that will reduce this kind of work."
"If we want to use more features, we have to pay more. There are multiple solutions on the cloud itself, but the pricing model package isn't consistent, which is confusing to clients."
"The troubleshooting has room for improvement."
 

Pricing and Cost Advice

"I rate the tool's pricing a one out of ten."
"Microsoft Sentinel requires an E5 license."
"From a cost perspective, Microsoft Sentinel is quite costly."
"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."
"We must have saved some money with this product. It is a cloud-native product, and the ingestion is per GB. Every GB costs a certain amount of money. That is how the license of Microsoft Sentinel works."
"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."
"We are charged based on the amount of data used, which can become expensive."
"It is certainly the most expensive solution. The cost is very high. We need to do an assessment using the one-month trial so that we can study the cost side. Before implementing it, we must do a careful calculation."
"Microsoft can enhance the licensing side. I feel there is confusion sometimes... They should have a single license in which we have the opportunity to use the EDR or CASB solution."
