Integrated auditing has strengthened data retention and improved incident investigations
I have seen areas for improvement, specifically in Microsoft Purview Audit or in general about Microsoft. I have had a situation with documentation. I had a customer who wanted to create alerts and they had Microsoft 365 Business Premium. In the documentation, it was noted that this license is enough for creating alerts. When we tried to make them, we noticed they cannot do it with Microsoft 365 E3 because the customer had limited features to manage alerts. The customer had to buy E3. We created Microsoft support requests, and they confirmed that the documentation displayed not the real situation and they have been going to update documentation. The same situation occurred now with implementing Microsoft Purview Audit in the last autumn. eDiscovery was combined with search and content search, and the documentation was not clear at the beginning. It was a little difficult to describe to customers that now it is a part of eDiscovery. Content search is a very simple functionality, while eDiscovery is a little difficult. I am not entirely sure why Microsoft is going in the way of combining these services because they are the same. However, for a customer who has never seen these services, it is difficult to understand quickly. The same situation occurs with litigation holds and some other holds. For any mail, I am trying to keep data. For example, emails are held for a year or two years, ten years, it does not matter. It is difficult to understand where to find this data and where these emails are being held. I need to use eDiscovery to find out all deleted data that was kept somewhere in some hidden folders of the mailbox. Regular customers and regular administrators know that on-premises Exchange, for example, allows them to find the data in some repository and review the list of kept data. However, with this hold, we do not have any functionality to review the list of kept data. It is difficult to understand for customers how to work with this. I had a case where I spent three or four hours working deeply with a customer to explain how to work with eDiscovery, why Content Search is not there when it was before, what is an eDiscovery case, and why we are talking about all of this just to review a list of kept emails. This is difficult.

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

"The overall user experience with Microsoft Purview Audit is of higher quality than when it was branded as Compliance Center, and Microsoft consistently updates and evolves functionalities and the overall experience."
"The main Microsoft feature is that it offers common integration of services, of data, of identity, meaning user accounts, user access, and privileged access."
"We're easily saving at least one hour per day using this solution."
"The platform has significantly enhanced our operational insight into the overall Microsoft 365 environment."
"Microsoft Sentinel delivers ROI mainly by reducing response time, improving analysis efficiency, and simplifying audits."
"It is quite efficient. It helps our clients in identifying their security issues and respond quickly. Our clients want to automate incident response and all those things."
"Sentinel has an intuitive, user-friendly way to visualize the data properly. It gives me a solid overview of all the logs. We get a more detailed view that I can't get from the other SIEM tools. It has some IP and URL-specific allow listing"
"It's pretty powerful and its performance is pretty good."
"The automation feature is valuable."
"It's a great product."
"The best functionality that you can get from Azure Sentinel is the SOAR capability. So, you can estimate any type of activity, such as when an alert was triggered or an incident was found."
"The signal correlation and dashboards features of Microsoft Sentinel are fantastic because it correlates the signal logs with other products."
 

Cons

"I had a case where I spent three or four hours working deeply with a customer to explain how to work with eDiscovery, why Content Search is not there when it was before, what is an eDiscovery case, and why we are talking about all of this just to review a list of kept emails."
"We do have a Denial of Access happening."
"Areas for product improvement include enhancing customization options and integrating more comprehensive compliance features."
"We are still in the early stages of leveraging Microsoft Purview Audit. Currently, it's primarily used for the audit function."
"If their UI was a bit more streamlined and easy to find when I need it, then that would be a great improvement."
"The built-in SOAR is not really good out-of-the-box. The SOAR relies on logic apps and you almost need to have some kind of developer background to be able to make these logic apps. Most security people cannot develop anything..."
"Sentinel could improve its ticketing and management. A few customers I have worked with liked to take the data created in Sentinel. You can make some basic efforts around that, but the customers wanted to push it to a third-party system so they could set up a proper ticketing management system, like ServiceNow, Jira, etc."
"If you're looking to use canned queries, the interface could be a little more straightforward. It's not immediately intuitive regarding how you use it. You have to take a canned query and paste it into an operational box and then you hit a button... They could improve the ease of deploying these queries."
"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."
"They can work on the EDR side of things... Every time we need to onboard these kinds of machines into the EDR, we need to do it with the help of Intune, to sync up the devices, and do the configuration. I'm looking for something on the EDR side that will reduce this kind of work."
"We'd like also a better ticketing system, which is older."
"The only thing is sometimes you can have a false positive."
 

Pricing and Cost Advice

Information not available
"Microsoft Sentinel requires an E5 license."
"I am not involved on the financial side, but from an enterprise-wide use perspective, I think the price is good enough."
"I don't know yet because they gave us a 30-day test window for free."
"It is certainly the most expensive solution. The cost is very high. We need to do an assessment using the one-month trial so that we can study the cost side. Before implementing it, we must do a careful calculation."
"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."
"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."
"It comes with a Microsoft subscription which the customer has, so they don't have to invest somewhere else."
"Microsoft is costlier. Some organizations may not be able to afford the cost of Sentinel orchestration and the Log Analytics workspace. The transaction hosting cost is also a little bit on the high side, compared to AWS and GCP."
