Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
5.6
Determining ROI from Microsoft Defender Vulnerability Management is challenging due to package inclusion and unclear financial benefits.
Sentiment score
7.3
Microsoft Sentinel enhances ROI with improved security, cost savings, automation, and faster threat detection, benefiting organizations efficiently.
As a Microsoft partner, we receive significant discounts, making the solution affordable for us.
If a customer is already using Microsoft’s ecosystem, the ROI can be positive due to seamless integration.
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
7.6
Microsoft Defender's customer service receives mixed reviews, highlighting inconsistent support and varying effectiveness in technical assistance.
Sentiment score
6.7
Microsoft Sentinel support is responsive and helpful, though basic support can be slow, with some preferring community resources.
They are sometimes responsive, however, often issues cannot be reproduced on their end, making it challenging.
The support we receive from Microsoft is declining, and for example, after taking advanced support, we have not received satisfactory answers.
My team raised multiple support tickets for the product, and we were able to get responses from Microsoft support team.
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.
 

Scalability Issues

Sentiment score
8.4
Microsoft Defender Vulnerability Management is praised for its high scalability and seamless integration, receiving consistently high user ratings.
Sentiment score
8.0
Microsoft Sentinel offers scalable, adaptable security solutions using Azure, ideal for various organizations with its flexible and updated features.
It is scalable; I evaluated the product and decided to use Defender on over 700 of our company servers.
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
6.6
Microsoft Defender is rated highly stable with 99% availability, despite minor portal, compatibility, logging, and memory issues.
Sentiment score
7.8
Microsoft Sentinel is highly reliable, with 99.9%+ availability and occasional minor issues, maintaining stability across diverse environments.
There are compatibility issues occasionally arising with false positives when other security tools are not whitelisted in Microsoft Defender.
It is very resource-intensive, consuming a lot of memory and CPU.
I would rate the overall stability as an eight.
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 Defender needs improvements in accuracy, customization, integration, resource efficiency, macOS support, user-friendliness, and affordability.
Microsoft Sentinel users seek better integration, user-friendliness, documentation, AI capabilities, and customizable features with improved performance and pricing.
This scoring should be for specific industries as well. If I belong to the healthcare industry using Microsoft Defender Vulnerability Management, it should provide me with a risk score and show how I fare against the risk score of my industry.
A vulnerability I patch within 15 minutes takes 24 additional hours for an update.
The product is not stable; it often uses excessive memory and CPU, which makes it slow.
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 Defender offers varying pricing; complex licensing may incur additional costs, but security benefits can justify the investment.
Microsoft Sentinel's usage-based pricing offers strong value with extensive integration, but cost unpredictability concerns some users.
Overall, every organization wishes for cheaper options, but we look at the security side as well, so we are good for now.
For non-partners, however, the cost could be seen as higher, between seven to ten.
The pricing is reasonable, and it's included in the whole Microsoft E5 bundle, so it's all-inclusive.
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.
 

Valuable Features

Microsoft Defender Vulnerability Management excels in integration, compliance, risk prioritization, and real-time assessments, enhancing security across diverse environments.
Microsoft Sentinel provides AI-driven automation, robust threat detection, scalability, and seamless integration for comprehensive security operations within the Microsoft ecosystem.
The main advantage of Microsoft Defender Vulnerability Management is that it can locate and prevent most threats even when the endpoints are not connected to the corporate network, as long as the internet is available.
The most valuable aspect is the kind of assessment results I get, and the recommendations provided in Microsoft products really help in taking care of the resources.
The integration with Sentinel has been one of the most valuable features for my organization.
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.
Microsoft Sentinel's ability to correlate data from multiple sources enhances our threat detection capabilities beyond what is a simple data lake solution by filtering out the noise and consolidating the signal down to a meaningful level that is easier to investigate and see.

Featured Reviews

NaySan @ Suraj Verma - PeerSpot reviewer
Provides actionable vulnerability insights and recommendations with notable efficiency
They may need to improve the portal refresh rate for Microsoft Defender Vulnerability Management because it takes time for recommendations to disappear after mitigation; sometimes, it takes one week, when it should ideally take only one to two hours. Overall, everything is good with Microsoft Defender Vulnerability Management, but the portal refresh rate can take up to seven days in some cases and three or four days in others to reflect changes.
