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.

Advanced AI-driven monitoring has strengthened investigations and now prioritizes critical threats
I would not say there is anything that could be better in SentinelOne Singularity AI SIEM; I think we have seen something unique in the product. This product has the potential to add more SOC functionality on top of its SIEM, which can automate a few more things because I have the information there. I need to do what I would call security agents or agentic AI to be built on top; it can take care of a lot more analysis and actions. Maybe licensing cost can also be looked at and reduced. We are still to see the automated feature work a little bit more; we are not really using it to the full extent.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Microsoft Sentinel has greatly increased our security."
"Sentinel has reduced the work involved in the event investigation by quite a lot."
"It is able to connect to an ever-growing number of platforms and systems within the Microsoft ecosystem, such as Azure Active Directory and Microsoft 365 or Office 365, as well as to external services and systems that can be brought in and managed. We can manage on-premises infrastructure. We can manage not just the things that are running in Azure in the public cloud, but through Azure Arc and the hybrid capabilities, we can monitor on-premises servers and endpoints. We can monitor VMware infrastructure, for instance, running as part of a hybrid environment."
"The log query feature has been the most valuable because it's very good. You can put your data on the cloud and run queues from Sentinel. It will do it all very fast. I love that I don't have to upload it to an Excel file and then manually look for a piece of information. Sentinel is much faster and is good for big databases."
"The product can integrate with any device."
"The automation rules and playbooks are the most useful that I've seen. A number of other places segregate the automation and playbook as separate tools, whereas Microsoft is a SIEM and SOAR tool in one."
"In Azure Sentinel, we have found, they do have a store in their capability. AI and intelligence features. We found that to be very helpful for us because some other things we do need to integrate again or find another vendor for the store"
"Microsoft Sentinel flags when admin credentials log in from an unusual location, automatically alerting the security team so they can investigate."
"AI-driven capabilities will give me real-time detection and will protect my autonomous AI interruption."
"After using SentinelOne Singularity AI SIEM, it has reduced our incident response time by forty to fifty percent compared to other tools."
"SentinelOne Singularity AI SIEM's AI-powered analytics does affect our SOC's ability to reduce false positives; that is one of the biggest advantages because the manpower that I have is limited."
"When they face attacks such as ransomware and are dissatisfied with their existing solutions, they switch to SentinelOne Singularity AI SIEM, which is quite good in detecting unknown threats, cleaning the system, and handling ransomware."
"Overall, I would assess the overall security posture after implementing SentinelOne Singularity AI SIEM as significantly better."
 

Cons

"Microsoft Sentinel is definitely costly. If we factor in the cost of other services, MCAS, MDI, and Microsoft Defender for Cloud, it gets seriously costly, to the extent that we cannot enable it across the organization."
"There is some relatively advanced knowledge that you have to have to properly leverage Sentinel's full capabilities."
"There is room for improvement in entity behavior and the integration site."
"If their UI was a bit more streamlined and easy to find when I need it, then that would be a great improvement."
"Its implementation could be simpler. It is not really simple or straightforward. It is in the middle. Sometimes, connectors are a little bit complex."
"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 have experienced some performance problems in the UK and, when we transferred to a different region, we lost some of our workspaces, which was shocking; if Microsoft needs to failover to another region, the customer should be informed because it affects many things."
"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."
"At the moment, I feel the pricing is a little bit on the higher side, but the tool is positioned in a place where risk is very high, and we do not want to take chances, so we are prepared to pay the premium."
"It is quite good, but the only downside is that it is costly."
"In AI SIEM, the areas that have room for improvement are the parsers for third-party integrated data or for third-party data sources that are not native integrations, which could be made a bit easier."
"Another area for improvement is that the product is somewhat expensive. Pricing could be improved as well."
"SentinelOne Singularity AI SIEM has some performance and reliability issues that need improvement."
 

Pricing and Cost Advice

"Currently, given our use case, the cost of Sentinel is justified, but it is expensive."
"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."
"It is consumption-based pricing. It is an affordable solution."
"Sentinel's pricing is on the higher side, but you can get a discount if you can predict your usage. You have to pay ingestion and storage fees. There are also fees for Logic Apps and particular features. It seems heavily focused on microtransactions, but they may be slightly optional. By contrast, Splunk requires no additional fee for their equivalent of Logic. You have a little more flexibility, but Sentinel's costs add up."
"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."
"Sentinel is a pay-as-you-go solution. To use it, you need a Log Analytics workspace. This is where the logs are stored and the cost of Log Analytics is based on gigabytes... On top of that, there is the cost of Sentinel, which is about €2 per gigabyte. If a customer has an M365 E5 license, the logs that come from Microsoft Defender are free."
"The price is reasonable because Sentinel includes features like user behavior analytics and SOAR that are typically sold separately. Overall, a standalone on-prem solution would require some high-end servers, and there's a different cost. It is a cloud-based solution, so there are backend cloud computing costs, but they are negligible."
"I don't know yet because they gave us a 30-day test window for free."
