Sentiment score
6.8

Sentiment score
8.1
SentinelOne Singularity Identity is highly stable with minimal disruptions, responsive support, and low CPU resource usage.
There are compatibility issues occasionally arising with false positives when other security tools are not whitelisted in Microsoft Defender.
information Security and IT Manager at Discover Dollar Technologies Pvt Ltd.
It is very resource-intensive, consuming a lot of memory and CPU.
Security Specialist at Prudential Systems Japan
If Microsoft experiences downtime, this solution goes down as it is a SaaS-based solution where we have no control.
Cloud Security Engineer at a computer software company with 51-200 employees
 

Room For Improvement

Microsoft Defender needs better false positive reduction, integration, cost management, risk scoring, and documentation for small enterprises.
SentinelOne Singularity Identity needs improved policies, interfaces, support, and features like reporting, updates, and integration for better usability.
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.
DGM. Technical Security at a tech services company with 10,001+ employees
A vulnerability I patch within 15 minutes takes 24 additional hours for an update.
information Security and IT Manager at Discover Dollar Technologies Pvt Ltd.
The product is not stable; it often uses excessive memory and CPU, which makes it slow.
Security Specialist at Prudential Systems Japan
There is a clear roadmap for improvements, including enhancing capabilities with AI and seamless functionality in an MSP model for deeper visibility across multiple agencies.
Senior Consultant at CGI
 

Setup Cost

Microsoft Defender Vulnerability Management provides economical tiered pricing with P1 and P2 options, often included in existing bundles.

For non-partners, however, the cost could be seen as higher, between seven to ten.
COO at Floating-Dot Technology LTD
The pricing is reasonable, and it's included in the whole Microsoft E5 bundle, so it's all-inclusive.
Corporate Planner at MISC Berhad
 

Valuable Features

SentinelOne Singularity Identity offers AI-driven security with dynamic threat detection, seamless management, and enhanced visibility for rapid remediation.

DGM. Technical Security at a tech services company with 10,001+ employees
The feature for customizing to region-specific and domain-specific requirements in healthcare is particularly beneficial.

OB
Microsoft Solutions Manager at Self-Employed
Ensures strong threat and vulnerability management with continuous risk assessment
The major priority is identity, which is crucial; we have lots of companies in manufacturing, energy, or various sectors, and it varies from one to another. I assess Microsoft Defender Vulnerability Management as very effective in continuously assessing vulnerabilities without requiring scans. We use automatic investigation and remediation features, safe attachments, safe links, and real-time reports, which are also very effective. For Active Directory, Defender has threat intelligence, and we are using that. The risk-based prioritization within Vulnerability Management affects my ability to manage vulnerabilities, particularly in relation to the Zero Trust Model utilized by our customers. The end-users often do as they please in their systems.
Roftiel Constantine - PeerSpot reviewer
Global Chief Information Security Officer at Barry-Wehmiller
Provides proactive threat remediation, reduces alert volume, and enhances incident response capabilities
During our pre-purchase evaluation of SentinelOne's EDR capabilities three years ago, we were consistently impressed by the positive relationships customers reported having with SentinelOne's engineers, sales teams, and customer success managers. These strong relationships, evident in the customers' unsolicited feedback, highlighted the "soft skills" and intangible qualities that SentinelOne possessed. This positive customer experience has been mirrored in our own interactions with them. Their responsiveness to our needs, particularly when addressing a couple of challenges we faced, has been excellent. They proactively scheduled weekly meetings to demonstrate their commitment to resolving our issues, a customer-centric approach I admire. SentinelOne's dedication to customer service, including their rapid technology updates and responsiveness to our suggestions, has been crucial to our success in protecting our organization. Their ability to quickly incorporate our needs into new releases is truly impressive and sets them apart. Overall, I highly recommend SentinelOne based on our positive interactions across all levels of their organization.
