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.

AI-driven monitoring has improved real-time threat detection but still needs better automation
I could see some workflows, but I am unable to do automated workflows. For example, some repetitive jobs or repetitive tasks I am doing, but I am trying to have less manual intervention on the front. I am raising some issues that should be resolvable. The SentinelOne team has told me that this can be resolved within a couple of months, but they are saying that it is in future for enhancement and it may take some time. So far, the numbers are great. Regarding disadvantages or areas for improvement, I could say that 35 percent of my manual effort can be detected since I implemented it very recently. I could be able to say my current data talks about only 35 percent, and it may improve further, as I am expecting. But I can only comment based on my alerts and events. The adoption rate will be less compared to other products, as this can be a time-taken process because all my data needs to be offloaded and the system needs to understand my existing alerts, logs, and other things. This will take some more time, probably another month. Another area for improvement is that the product is somewhat expensive. Pricing could be improved as well.

Quotes from Members

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

Pros

"The comprehensiveness of Sentinel's security protection is really great."
"Sentinel has features that have helped improve our security poster. It helped us in going ahead and identifying the gaps via analysis and focusing on the key elements."
"It's a great product."
"There are some very powerful features to Sentinel, such as the integration of various connectors. We have a lot of departments that use both IaaS and SaaS services, including M365 as well as Azure services. The ability to leverage connectors into these environments allows for large-scale data injection."
"For those who want to adopt Sentinel, I'd advise that it's a really one-stop solution for all the security needs."
"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."
"Microsoft Sentinel has improved cost efficiency, which is one of the key areas we're able to win business against the ability to have threat intelligence."
"It's pretty powerful and its performance is pretty good."
"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."
"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."
"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."
"Overall, I would assess the overall security posture after implementing SentinelOne Singularity AI SIEM as significantly better."
 

Cons

"At the network level, there is a limitation in integrating some of the switches or routers with Microsoft Sentinel. Currently, SPAN traffic monitoring is not available in Microsoft Sentinel. I have heard that it is available in Defender for Identity, which is a different product. It would be good if LAN traffic monitoring or SPAN traffic monitoring is available in Microsoft Sentinel. It would add a lot of value. It is available in some of the competitor products in the market."
"The pricing tiers of Microsoft Sentinel should be improved. There are complexities in calculating the right pricing tier for different customers, which makes it difficult for me as a consultant during upfront pricing."
"Some of the data connectors are outdated, at least the ones that utilize Linux machines for log forwarding."
"Currently, the watchlist feature is being utilized, and although there have been improvements, it is still not fully optimized."
"Multi-tenancy, in my opinion, needs to be improved. I believe it can do better as a managed service provider."
"There is a wider thing called Jupyter Notebooks, which is around the automation side of things. It would be good if there are playbooks that you can utilize without having to have the developer experience to do it in-house. Microsoft could provide more playbooks or more Jupyter Notebooks around MITRE ATT&CK Framework."
"We'd like also a better ticketing system, which is older."
"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."
"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."
"It is quite good, but the only downside is that it is costly."
"SentinelOne Singularity AI SIEM has some performance and reliability issues that need improvement."
"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."
"Another area for improvement is that the product is somewhat expensive. Pricing could be improved as well."
 

Pricing and Cost Advice

"Microsoft Sentinel is expensive."
"It's costly to maintain and renew."
"Microsoft Sentinel can be costly, particularly for data management."
"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."
"In comparison to other security solutions, Microsoft Sentinel offers a reasonable price for the features included."
"Microsoft Sentinel is included in our E5 license."
"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."
"Microsoft Sentinel requires an E5 license."
