Sentiment score
7.3
Microsoft Sentinel enhances ROI with improved security, cost savings, automation, and faster threat detection, benefiting organizations efficiently.
The process is reduced from weeks to a day, showcasing a solid nine for return on investment.

We attribute our growth to Sentinel.
From a risk perspective, it's about mitigating risk, and as mentioned earlier, we haven't missed many things since we've had the offering in market—only a couple of minor incidents.
 

Customer Service

Sentiment score
4.7
Microsoft Purview Compliance Manager support faces mixed reviews, citing long resolution times and outsourced staff inefficiencies.
Sentiment score
6.7
Microsoft Sentinel support is responsive and helpful, though basic support can be slow, with some preferring community resources.
Since I approach them with more complicated issues, it takes quite a bit of time to get through those two support tiers.
The support staff, who are often outsourced, seem not adequately equipped to handle issues quickly and efficiently.
The quality of support is affected because most support staff seem focused on obtaining five-star ratings rather than resolving problems thoroughly.
Their solutions' integration simplifies resolving issues compared to those caused by third-party products.
Working with a Sentinel engineer helped us tune settings effectively.
When my team needs to escalate issues to Microsoft, especially for Microsoft Sentinel, the response is fast through their French entity.

Microsoft Purview Compliance Manager excels in scalable deployment across environments but faces constraints in crafting detailed policies.
Sentiment score
8.0
Microsoft Sentinel offers scalable, adaptable security solutions using Azure, ideal for various organizations with its flexible and updated features.
As services increase, eDiscovery capabilities also increase, allowing easy deployment.
It is straightforward since it scans everything, covering all aspects needed in our operations.
While the solution is scalable in terms of user numbers, there are limitations when creating more granular level policies.
Office 365 and Exchange are running on it, covering about 35,000 users efficiently.
As our organization uses Microsoft Azure and Defender, everything grows together, and we can integrate various features seamlessly.
Being a SaaS solution, the scalability of Microsoft Sentinel is robust.
 

Stability Issues

Sentiment score
7.9
Microsoft Purview Compliance Manager is reliable but needs improved eDiscovery and search functionality despite regular updates and changes.
Sentiment score
7.8
Microsoft Sentinel is highly reliable, with 99.9%+ availability and occasional minor issues, maintaining stability across diverse environments.
Despite stability, it needs to be more user-friendly and competitive compared to other eDiscovery tools.
It is reliable and I can depend on it.
In terms of latency, stability is not an issue.
So far, we have not experienced any issues, and it has been stable from the beginning.
In the past two years, our team hasn't encountered any issues with the stability of Microsoft Sentinel from an operations perspective.
I need to be aware of deprecated connectors as they may disconnect, but the data continues to be sent with a need for quick adaptation.
 

Room For Improvement

Microsoft Purview Compliance Manager needs integration, UI improvements, cost reduction, and enhanced policy and monitoring features for better usability.
Microsoft Sentinel users seek better integration, user-friendliness, documentation, AI capabilities, and customizable features with improved performance and pricing.
Microsoft Copilot Security converts human language to search queries using its AdLM language model.
The speed and accessibility, particularly in the user interface, require significant work.
The Purview Compliance Portal's log management could be more user-friendly, making data retrieval, like email logs, challenging.
We have some tools, such as our off-site Meraki firewalls, that have not fully integrated with Sentinel.
Currently, we are happy to have a way in the middle with not so much cost, but it would be nice to have the ability to enhance the automation of workflows based on learned incidents.
There are complexities in calculating the right pricing tier for different customers, which makes it difficult for me as a consultant during upfront pricing.
 

Setup Cost

Microsoft Purview Compliance Manager offers cost-efficient pricing, especially for existing Microsoft users, and is notably cheaper than competitors.
Microsoft Sentinel's usage-based pricing offers strong value with extensive integration, but cost unpredictability concerns some users.
I rate the pricing as a one since it is included in what I am already paying for, as part of the Microsoft 365 E5 licensing.
Microsoft Purview Compliance Manager is priced at 60% to 70% compared to some competitors.
Microsoft Sentinel offers more capabilities than Bastion, with a more intuitive experience.
Setting up the right cost model for customers is intricate, requiring careful consideration of various components and licensing tiers.
The ingestion costs for the data analytics is usually the highest cost.

Microsoft Sentinel provides AI-driven automation, robust threat detection, scalability, and seamless integration for comprehensive security operations within the Microsoft ecosystem.

The most valuable feature is data classification retention since I deal with terabytes of data, and managing and monitoring it simplifies the process.
The best aspect is that it requires little to no time for implementation if I am using all of Microsoft's tools.
Microsoft Sentinel's ability to correlate data from multiple sources and its detection capabilities are essential.
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.

Streamlined data management and improved compliance with efficient document classification
The most valuable feature is data classification retention since I deal with terabytes of data, and managing and monitoring it simplifies the process. Additionally, the system provides a dashboard showing our compliance status, which aids in managing compliance tasks. The compliance score feature allows me to assess and compare our compliance across organizations. I've also noticed efficiency gains, especially in handling subject access requests. Previously, these tasks were manual and time-consuming, but now they are streamlined, reducing the process from weeks to just a day.
