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 UI is the most valuable feature."
"The system is stable; I haven't encountered any worldwide stability issues unlike other office products."
"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 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."
"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."
"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."
"We can use Sentinel's playbook to block threats. It covers all of the environment, giving us great visibility."
"Microsoft Sentinel's ability to correlate data from multiple sources has improved our capability significantly."
"Sentinel is a full-fledged SIEM and SOAR solution, made to enhance your security posture and entirely centered around enhancing security."
"The most valuable feature is the onboarding of the workloads. You can see all that has been onboarded in your account on the dashboards."
"The most valuable feature is the performance because unlike legacy SIEMs that were on-premises, it does not require as much maintenance."
"Microsoft Sentinel stands out mainly for its signal-to-noise reduction; LogRhythm required numerous AI rules to reach a similar level of noise reduction."
"After two years, the return on investment has been absolutely staggering because by deploying Sentinel, we pretty much have a 24/7 AI that's looking at signals, metrics, and alerts, making decisions, applying automated actions, and saving us from having to double the amount of staff we have now with about a 40% reduction in costs."
 

Cons

"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 initial setup took longer than we expected. Microsoft Purview Data Lifecycle Management is not a turn-it-on-and-go product."
"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 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..."
"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."
"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."
"I believe one of the challenges I encountered was the absence of live training sessions, even with the option to pay for them."
"We do have in-built or out-of-the-box metrics that are shown on the dashboard, but it doesn't give the kind of metrics that we need from our environment whereby we need to check the meantime to detect and meantime to resolve an incident. I have to do it manually. I have to pull all the logs or all the alerts that are fed into Sentinel over a certain period. We do this on a monthly basis, so I go into Microsoft Sentinel and pull all the alerts or incidents we closed over a period of thirty days."
"There is room for improvement in terms of integrations."
"When it comes to ingesting Azure native log sources, some of the log sources are specific to the subscription, and it is not always very clear."
"There is some relatively advanced knowledge that you have to have to properly leverage Sentinel's full capabilities."
 

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."
"The are two native advantages for customers that use M365 Security and Sentinel. The first advantage is that the log or security-event ingestion into Sentinel is free. Cost-wise, they're saving a lot and that is a major advantage."
"The solution is expensive and there is a daily usage fee."
"From a cost perspective, there are some additional charges in addition to the licensing."
"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."
"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."
"From a cost point of view, it is not a cheap product. It's, like, an enterprise-level application. So if you compare it with a low-level application, it's expensive, but if you compare it with the same-level application, it's pretty much cost-effective, I think."
"I don't know yet because they gave us a 30-day test window for free."
"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."
