ROI

5.6
Assessing financial benefits of Microsoft Defender Vulnerability Management is difficult due to bundled services, partnerships, and diverse vendor use.
Sentiment score
7.1
Microsoft Sentinel offers mixed ROI, improving efficiency and security, with high initial costs but potential positive long-term returns.
Organizations typically do not rely solely on Microsoft products to avoid putting all eggs in one basket, which presents a challenge for maximizing ROI.
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
7.2
Microsoft Defender Vulnerability Management support receives mixed reviews due to varying communication efficiency and outsourced team knowledge levels.
Sentiment score
6.6
Microsoft Sentinel support is generally positive, with quick responses and valuable documentation, though high-tier issues exist.
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.
They are familiar with Microsoft products but are not direct Microsoft staff, which is an area needing improvement.
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.

8.2
Microsoft Defender Vulnerability Management excels in scalability and integration, satisfying diverse enterprises with seamless cloud-based performance and expansion.
Sentiment score
7.9
Microsoft Sentinel efficiently scales in diverse environments with easy integration, automatic scaling, and satisfactory performance, despite cost concerns.
The integration is straightforward for those who understand it, though documentation needs improvement.
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
6.4
Microsoft Defender is generally stable but faces issues with false positives, resource intensity, and occasional logging errors.
Sentiment score
7.8
Microsoft Sentinel is stable and reliable, with minimal downtime, excellent uptime, and occasional minor manual interventions needed.
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.
If Microsoft experiences downtime, this solution goes down as it is a SaaS-based solution where we have no control.
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 Vulnerability Management needs enhanced accuracy, better integration, user-friendliness, cost-effectiveness, and improved platform management and reporting.
Microsoft Sentinel users desire better integrations, clearer features, improved speed, enhanced AI, and streamlined processes for effective use.
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

Enterprise users report mixed views on Microsoft Defender's pricing, noting competitive rates, but caution significant costs without discounts.
Microsoft Sentinel's cost perception varies, offering flexibility and integration benefits, yet data volume can significantly impact expenses.
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 provides compliance, integration, threat identification, accurate assessments, and streamlined management for enhanced security and efficient vulnerability handling.
Microsoft Sentinel integrates seamlessly with Microsoft tools, using AI for threat detection, automation, and providing comprehensive threat management.
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 feature for customizing to region-specific and domain-specific requirements in healthcare is particularly beneficial.
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.
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

Krishna R - PeerSpot reviewer
Achieve comprehensive endpoint and identity protection with continuous real-time monitoring
I have not thought about improvements for Microsoft Defender Vulnerability Management as of now, but this is typically an operational maintenance process. The operational maintenance process refers to these products being part of day-to-day operations. Threats keep coming almost daily, and we need to run it, prioritize the risk, and apply the patches. I am not able to think of many features for improvement at this point in time. There should be risk scoring added to Microsoft Defender Vulnerability Management; specifically, they call it quantification of the risk. If they can provide peer site reviews or risk scoring, such as how my organization in the healthcare industry fares against my peers on average, it would be valuable information. 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. If there are guidelines or insights on this, it will compel customers to reduce risk levels or improve their risk scores. The application block capabilities in Microsoft Defender Vulnerability Management are effective and up to the standards, as everybody is looking at open OSINT and open-source security packages. I think on CV scoring, they are aligned with the industry.
