Automated retention has transformed compliance workflows and now simplifies audit responses
The deep native integration with Microsoft 365 is what ultimately made me decide on Microsoft Purview Data Lifecycle Management over Enterprise Vault and OpenText Content Manager. Auto-apply retention labels using machine learning is the specific integration with Microsoft 365 that made it the deciding factor for me over Enterprise Vault or OpenText. Manually labeling content at our data volumes is not realistic. The automated classification based on sensitive information types and trainable classifiers is what makes the program actually scale. That feature gets used constantly. We went from inconsistent ad-hoc retention practices to a consistent, automated, documented program across the whole organization with Microsoft Purview Data Lifecycle Management. That shift from a compliance audit perspective is enormous.

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

"We went from inconsistent ad-hoc retention practices to a consistent, automated, documented program across the whole organization with Microsoft Purview Data Lifecycle Management."
"The system is stable; I haven't encountered any worldwide stability issues unlike other office products."
"The UI is the most valuable feature."
"The impact of Microsoft Purview Data Lifecycle Management on my unified data catalog has improved a lot; the improvements I see are in the lineage, the discovery, and the labeling."
"The product is extremely cost-effective and affordable for customers."
"One of the most valuable features is that it creates a kind of a single pane of glass for organizations that already use Microsoft software. So, when they have things like Microsoft 365, it is very easy for them to kind of plug in or enroll those endpoints into the Azure Sentinel service."
"The query language of Microsoft Sentinel is easy to understand and use."
"The main benefit is that as companies migrate their systems and services into the Cloud, especially if they're migrating into Azure, they've got a native SIEM available to them immediately."
"Microsoft Sentinel is cloud native, which is a significant advantage. The data connectors that provide the ability to connect third-party log sources are highly valuable."
"The data connectors that Microsoft Sentinel provides are easy to integrate when we work with a Microsoft agent."
"It's a great product."
"For those who want to adopt Sentinel, I'd advise that it's a really one-stop solution for all the security needs."
 

Cons

"Microsoft's Purview Data Lifecycle Management preview features can be unreliable, hindering their usefulness."
"The time it takes to scan is one issue; when we raise high-volume issues and tickets related to scanning failures, it relates to permission errors, which are technical challenges."
"I think labeling could use a lot more AI assistance. AI implementation into labeling would be beneficial."
"The initial setup took longer than we expected. Microsoft Purview Data Lifecycle Management is not a turn-it-on-and-go product."
"There is some relatively advanced knowledge that you have to have to properly leverage Sentinel's full capabilities."
"Improvement-wise, I would like to see more integration with third-party solutions or old-school antivirus products that have some kind of logging capability. I wouldn't mind having that exposed within Sentinel. We do have situations where certain companies have bought licensing or have made an investment in a product, and that product will be there for the next two or three years. To be able to view information from those legacy products would be great. We can then better leverage the Sentinel solution and its capabilities."
"The pricing could be improved."
"I think a lot of customers don't fully understand the full capabilities of Azure Sentinel yet."
"The costs and pricing of Microsoft Sentinel are expensive. That's my biggest complaint, especially from customers who are concerned about the significant expense."
"If we want to use more features, we have to pay more. There are multiple solutions on the cloud itself, but the pricing model package isn't consistent, which is confusing to clients."
"In New Zealand, there are customers that run dual stack, running Microsoft but also competitor products, EDR software, cloud security software, and other tooling. While it's improved over the last four or five years, there's still more work that can be done to integrate better outside of the Microsoft ecosystem."
"We've seen delays in getting the logs from third-party solutions and sometimes Microsoft products as well. It would be helpful if Microsoft created a list of the delays. That would make things more transparent for customers."
 

Pricing and Cost Advice

"The service operates on a pay-as-you-go basis, charging an extra one cent per field of metadata scanned in our data."
"It is a consumption-based license model. bands at 100, 200, 400 GB per day etc. Azure Sentinel Pricing | Microsoft Azure"
"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."
"Microsoft Sentinel's pricing is relatively expensive and extremely confusing."
"Sentinel is costly."
"I'm not happy with the pricing on the integration with Defender for Endpoint. Defender for Endpoint is log-rich. There is a lot of information coming through, and it is needed information. The price point at which you ingest those logs has made a lot of my customers make the decision to leave that within the Defender stack."
"I am just paying for the log space with Azure Sentinel. It costs us about $2,000 a month. Most of the logs are free. We are only paying money for Azure Firewall logs because email logs or Azure AD logs are free to use for us."
"We are charged based on the amount of data used, which can become expensive."
"I have had mixed feedback. At one point, I heard a client say that it sometimes seems more expensive. Most of the clients are on Office 365 or M365, and they are forced to take Azure SIEM because of the integration."
