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."
"It enabled customers that previously found it difficult to justify the cost of a security-analytics platform to actually deploy one without enormous upfront costs."
"The product can integrate with any device."
"Microsoft Sentinel provides me with a unified set of tools to detect, investigate, and respond to incidents, which is something I greatly value."
"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."
"Azure Sentinel is actually quite handy, and very adaptive to the market trends."
"The query language of Microsoft Sentinel is easy to understand and use."
"The analytic rule is the most valuable feature."
"For the people who are on the cloud, I would suggest they go for Sentinel regardless of any other SIEM, as it will do a good integration with other solutions and with other cloud providers while providing a holistic view as well."
 

Cons

"Graylog Security needs to incorporate security scorecards."
"If I can use Sentinel offline at home and use it on a local network, it would be great. I'm not sure if I can use Sentinel offline versus the tools I have."
"The playbook development environment is not as rich as it should be. There are multiple occasions when we face problems while creating the playbook."
"While I appreciate the UI itself and the vast amount of information available on the platform, I'm finding the overall user experience to be frustrating due to frequent disconnections and the requirement to repeatedly re-authenticate."
"We do have in-built or out-of-the-box metrics that are shown on the dashboard, but it doesn't give the kind of metrics that we need from our environment whereby we need to check the meantime to detect and meantime to resolve an incident. I have to do it manually. I have to pull all the logs or all the alerts that are fed into Sentinel over a certain period. We do this on a monthly basis, so I go into Microsoft Sentinel and pull all the alerts or incidents we closed over a period of thirty days."
"The following would be a challenge for any product in the market, but we have some in-house apps in our environment... our apps were built with different parameters and the APIs for them are not present in Sentinel. We are working with Microsoft to build those custom APIs that we require. That is currently in progress."
"We are invoiced according to the amount of data generated within each log."
"Professional support is not that great. Often, I'd rather not involve them."
"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."
 

Pricing and Cost Advice

"I rate the tool's pricing a one out of ten."
"From a cost perspective, there are some additional charges in addition to the licensing."
"The solution is expensive and there is a daily usage fee."
"Sentinel is a bit expensive. If you can figure a way of configuring it to meet your needs, then you can find a way around the cost."
"The pricing is reasonable, and we think Sentinel is worth what we pay for it."
"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 costly."
"It is a consumption-based license model. bands at 100, 200, 400 GB per day etc. Azure Sentinel Pricing | Microsoft Azure"
"No license is required to make use of Sentinel, but you need to buy products to get the data. In general, the price of those products is comparable to similar products."
