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

"One of the most valuable features of Microsoft Sentinel is that it's cloud-based."
"The dashboard that allows me to view all the incidents is the most valuable feature."
"The main benefit is the ease of integration."
"Sentinel's most important feature is the ability to centralize all the logs in one place. There's no need to search multiple systems for information."
"Sentinel improved how we investigate incidents. We can create watchlists and update them to align with the latest threat intelligence. The information Microsoft provides enables us to understand thoroughly and improve as we go along. It allows us to provide monthly reports to our clients on their security posture."
"Mainly, this is a cloud-native product. So, there are zero concerns about managing the whole infrastructure on-premises."
"The analytics has a lot of advantages because there are 300 default use cases for rules and we can modify them per our environment. We can create other rules as well. Analytics is a useful feature."
"The Identity Behavior tab furnishes us with the entire history linked to each IP or domain that has either accessed or attempted to access our system."
"The security level that they are maintaining with the pre-authentication keys is very good."
 

Cons

"Given that I am in the small business space, I wish they would make it easier to operate Sentinel without being a Sentinel expert. Examples of things that could be easier are creating alerts and automations from scratch and designing workbooks."
"The AI capabilities must be improved."
"My primary improvement request would be for auxiliary logs, as they represent our biggest need."
"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."
"I believe one of the challenges I encountered was the absence of live training sessions, even with the option to pay for them."
"If Azure Sentinel had the ability to ingest Azure services from different tenants into another tenant that was hosting Azure Sentinel, and not lose any metadata, that would be a huge benefit to a lot of companies."
"The KQL query does not function effectively with Windows 11 machines, and in the majority of machine-based investigations, KQL queries are essential for organizing the data during investigations."
"The reporting could be more structured."
"The solution could improve by providing better documentation for beginners to learn, such as videos or other tutorials."
 

Pricing and Cost Advice

"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."
"Microsoft Sentinel is included in our E5 license."
"There are no additional costs other than the initial costs of Sentinel."
"The combination of the ease of accessibility and the free cost of the service is great. But we buy storage based on our events per second and on how many sources are integrated into the solution."
"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."
"Sentinel is costly compared to other solutions, but it's fair. SIEM solutions like CrowdStrike charge based on daily log volume. They generally process a set number of logs for free before they start charging. Microsoft's pricing is clearer. It's free under five gigabytes. Some of these logs we ingest have a cost, so they don't hide it. I believe the tenant pays the price, and Microsoft helps create awareness of the cost."
"The pricing isn't very high. It depends on the number of logs you have. If you're expecting to ingest 50 to 60G in a day, but you're only ingesting 20 to 25G per day at first and you have a good team to analyze the logs, then you can segregate the ingestion at under 15G."
"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."
"The solution is not expensive for the data security measure you receive, it is reasonable."
