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 faster response due to automation of the playbooks has cut MTTR by 50 to 60%, especially for repetitive incidents."
"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."
"It is quite efficient, and it helps our clients in identifying their security issues and respond quickly."
"Sentinel is a SIEM and SOAR tool, so its automation is the best feature; we can reduce human interaction, freeing up our human resources."
"The UI of Sentinel is very good and easy to use, even for beginners."
"One of the most valuable features of Microsoft Sentinel is that it's cloud-based."
"There are a lot of things you can explore as a user. You can even go and actively hunt for threats. You can go on the offensive rather than on the defensive."
"I recommend implementing Sentinel because it's certainly the most powerful SIEM tool."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"The AI capabilities must be improved."
"Microsoft Sentinel can be improved in that the way it is built today means if you have a third party and you pay for ingestion, this is different than how some of the traditional SIEMs work."
"We do see continuous improvement all the time, however, I haven't got a specific feature that is lacking or not well designed."
"They should integrate it with many other software-as-a-service providers and make connectors available so that you don't have to do any sort of log normalization."
"Microsoft Sentinel's ability to correlate data from multiple sources does not enhance our threat detection capabilities beyond what a simple data lake solution could offer, as we are a developer, so it is not necessarily applicable."
"I would like Microsoft Sentinel to enhance its SOAR capabilities."
"Sometimes you will find some network issue and network error with the Azure Sentinel portal. That's the biggest drawback I found with the Sentinel."
"Technical support doesn't understand the features well enough. Their solutions and response time aren't very good."
 

Pricing and Cost Advice

"I rate the tool's pricing a one out of ten."
"Microsoft Sentinel's pricing is relatively expensive and extremely confusing."
"In comparison to other security solutions, Microsoft Sentinel offers a reasonable price for the features included."
"The pricing is based on how much you ingest, so it's pretty straightforward. There are no tiers, and you pay for what you use unlike with other types of SIEM solutions that are usually based on tiers."
"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."
"It is consumption-based pricing. It is an affordable solution."
"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."
"From a cost perspective, there are some additional charges in addition to the licensing."
"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."
