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

"The system is stable; I haven't encountered any worldwide stability issues unlike other office products."
"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 UI is the most valuable feature."
"HPE Apollo Systems has positively impacted our organization by improving business operations by eighty percent, saving time, improving efficiency, and facilitating the management of large data sets."
"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 UI-based analytics are excellent."
"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 pricing is good"
"Investigations are something really remarkable. We can drill down right to the raw logs by running different queries and getting those on the console itself."
"What is most useful, is that it has a good connection to the Microsoft ecosystem, and I think that's the key part."
"For the people who are on the cloud, I would suggest they go for Sentinel regardless of any other SIEM, as it will do a good integration with other solutions and with other cloud providers while providing a holistic view as well."
"The most valuable feature is the performance because unlike legacy SIEMs that were on-premises, it does not require as much maintenance."
"I believe one of the main advantages is Microsoft Sentinel's seamless integration with other Microsoft products."
 

Cons

"Microsoft's Purview Data Lifecycle Management preview features can be unreliable, hindering their usefulness."
"The initial setup took longer than we expected. Microsoft Purview Data Lifecycle Management is not a turn-it-on-and-go product."
"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."
"There is no specific improvement I would suggest for Microsoft Purview Data Lifecycle Management, but I think if they can work on policy design and usability, adding more granular control for the organization regarding controlling the movement of data outside would definitely improve the solution."
"The solution could be more user-friendly; some query languages are required to operate it."
"Sometimes, we are observing large ingestion delays. We expect logs within 5 minutes, but it takes about 10 to 15 minutes."
"For certain vendors, some of the data that Microsoft Sentinel captures is redacted due to privacy reasons."
"Professional support is not that great. Often, I'd rather not involve them."
"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."
"We'd like to see more connectors."
"If Sentinel had a graphical user interface, it would be easier to use. I would also like it to be more customizable."
"Sentinel's pricing is on the higher side, but you can get a discount if you can predict your usage."
 

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."
"Pricing for Microsoft Sentinel could always be lower, but it's workable. The ingestion costs for the data analytics is usually the highest cost, but the licensing per Microsoft Sentinel is fairly straightforward and transparent."
"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."
"Sentinel is costly."
"Sentinel is expensive relative to other products of the class, so it often isn't affordable for small-scale businesses. However, considering the solution has more extensive capabilities than others, the price is not so high. Pricing is based on GBs of ingested daily data, either by a pay-as-you-go or subscription model."
"The pricing is reasonable, and we think Sentinel is worth what we pay for it."
"Sentinel is a bit expensive. If you can figure a way of configuring it to meet your needs, then you can find a way around the cost."
"Azure Sentinel is very costly, or at least it appears to be very costly. The costs vary based on your ingestion and your retention charges."
"Good monthly operational cost model for the detection and response outcomes delivered, M365 logs don't count toward the limits which is a good benefit."
