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.

Vice President, Sales, Cybersecurity at a computer software company with 51-200 employees

Microsoft Sentinel gives me a unified set of tools to detect, investigate, and respond to incidents. This unified approach is very important to me. That was one of the main reasons we moved to Microsoft because of the single approach. It allowed us to action the threats faster than going into multiple portals. My impression of the effectiveness of AI and machine learning in enhancing threat detection and response with Microsoft Sentinel has been positive. We are in the pilot phase for that, and so far the results are pretty good. Microsoft Sentinel's ability to correlate data from multiple sources has enhanced my threat detection capabilities beyond what a simple data solution could offer since we are using all Microsoft, and we use a few third parties that we use MCAS for, but so far it's been with the APIs, it's pretty good. I don't have metrics apart from reducing the time it takes from our traditional SOC to Microsoft Sentinel; it has drastically reduced the time by less than half. My advice to another organization considering it is that if you're using all Microsoft, you should be using Microsoft Sentinel since it's free. A good data point is that we haven't been hacked yet, which is a good indicator. We are able to catch the threats early and respond to them. What led us to change over was the fact that everything was Microsoft. What stood out to me was getting all of Microsoft. I would rate this product a 7.

I find the features of Microsoft Sentinel that are most valuable are the breakdown of the details that come in from Microsoft Sentinel's alert status, which are really helpful and they lead you in the right direction. It is integrated into our ServiceNow more easily than other vendors we have dealt with in the past from a SIEM perspective that are not providing the managed service on their own. Microsoft Sentinel gives me a unified set of tools to detect, investigate, and respond to incidents. I cannot speak to the response side because we are not doing a lot of automated response, but definitely from the detection and investigation side. The unified approach of Microsoft Sentinel is very important to me. With anything we do, because it is going to cut down on time for engineers to identify the issue and remediate it. There is a predictable cost across the board. I work for a managed service provider, so we are not working in a large enterprise, we are working across hundreds of different customers. So we can actually go and say, "Hey, company of this size, we can sell it to you, and this is how much it is going to cost you." From a training perspective, it makes it much easier to train not only the people coming in that are doing the higher level work, but also the people who are taking the calls initially, such as our SOC engineers that are doing the initial triage, to say that you have to go into this portal and look at this thing. All of these are going to aggregate together. Instead of saying, "Okay, you have to hop here. Then if this is the problem, you have to hop over here." Being able to dictate and train efficiently and in a streamlined way is probably the most value proposition we have for something in this category.
