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 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 system is stable; I haven't encountered any worldwide stability issues unlike other office products."
"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."
"There are a lot of things you can explore as a user. You can even go and actively hunt for threats. You can go on the offensive rather than on the defensive."
"Microsoft Sentinel has helped by streamlining our security. We have a nine-member network team, with three members managing security for the city, and Sentinel allows us to operate an unofficial SOC."
"Microsoft Sentinel provides the capability to integrate different log sources. On top of having several data connectors in place, you can also do integration with a threat intelligence platform to enhance and enrich the data that's available. You can collect as many logs and build all the use cases."
"When M365 Security is combined with Sentinel it gives the customer more power to remediate attacks faster, and detection and response are more powerful when M365 Defender and Sentinel are combined, compared to a customer going with a third-party solution and Sentinel."
"Microsoft Sentinel is an awesome SIEM/SOAR tool for customers with active Cloud presence."
"The return on investment is massive because with a small amount of money, customers can take advantage of an array of technologies since everything is connected from the Microsoft perspective."
"The SOAR playbooks are Sentinel's most valuable feature. It gives you a unified toolset for detecting, investigating, and responding to incidents. That's what clearly differentiates Sentinels from its competitors. It's cloud-native, offering end-to-end coverage with more than 120 connectors. All types of data logs can be poured into the system so analysis can happen. That end-to-end visibility gives it the advantage."
"Sentinel pricing is good"
 

Cons

"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."
"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."
"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."
"I think labeling could use a lot more AI assistance. AI implementation into labeling would be beneficial."
"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."
"The playbook development environment is not as rich as it should be. There are multiple occasions when we face problems while creating the playbook."
"There is some relatively advanced knowledge that you have to have to properly leverage Sentinel's full capabilities. I'm thinking about things like the creation of workbooks, how you do threat-hunting, and the kinds of notifications you're getting... It takes time for people to ramp up on that and develop a familiarity or expertise with it."
"With one of my clients, we deployed the solution. We estimated that the ingestion would be up to this particular mark, but that ingestion somehow got way beyond that. Within a month to a month and a half, they got charged 35,000 CAD, which was a huge turn off for us."
"Azure Sentinel will be directly competing with tools such as Splunk or Qradar. These are very established kinds of a product that have been around for the last seven, eight years or more."
"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..."
"Technical support doesn't understand the features well enough. Their solutions and response time aren't very good."
"The learning curve could be improved. I am still learning it. We were able to implement the basic features to get them up and running, but there are still so many things that I don't know about all its features. They have a lot of features that we have not been able to use or apply. If they could work on reducing the solution's learning curve, that would be good. While there is a training course held by Microsoft to learn more about this solution, there is a cost associated with it."
 

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 varies on a case-by-case basis. It is about $2,000 per month. The cost is very low in comparison to other SIEMs if you are already a Microsoft customer. If you are using the complete Microsoft stack, the cost reduces by almost 42% to 50%. Its cost depends on the number of logs and the type of subscription you have. You need to have an Azure subscription, and there are charges for log ingestion, and there are charges for the connectors."
"No license is required to make use of Sentinel, but you need to buy products to get the data. In general, the price of those products is comparable to similar products."
"It is kind of like a sliding scale. There are different tiers of pricing that go from $100 per day up to $3,500 per day. So, it just kind of depends on how much data is being stored. There can be additional costs to the standard license other than the additional data. It just kind of depends on what other services you're spinning up in Azure, or if you're using something like Azure log analytics."
"Sentinel can be expensive. When you ingest data from sources that are outside of the cloud, you're paying a fair amount for that data ingestion. When you're ingesting data sources from within the cloud, depending on what your retention periods are, it's not that expensive."
"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."
"There are no additional costs other than the initial costs of Sentinel."
"The pricing is reasonable, and we think Sentinel is worth what we pay for it."
"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."
