ROI

4.9
Determining ROI for Microsoft Defender Vulnerability Management is challenging due to service bundling and mixed-use of other products.

6.5
NinjaOne streamlines operations, enabling remote resolutions and productivity boosts, with most organizations seeing cost and workload reductions quickly.

6.6
Microsoft Defender Vulnerability Management is highly stable and reliable, with minimal downtime, despite minor resource-related and compatibility issues.
Sentiment score
8.2
Users find NinjaOne reliable and stable due to frequent updates, despite occasional minor issues with remote command execution.
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.
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
I would rate the stability a ten out of ten.
Owner at AvalisNT AG

Room For Improvement

Microsoft Defender needs better false positive reduction, integration, cost management, risk scoring, and documentation for small enterprises.
NinjaOne requires reporting, interface, integration, and feature improvements, addressing cost, usability, and security concerns for a better user experience.
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.

The product is not stable; it often uses excessive memory and CPU, which makes it slow.
Security Specialist at Prudential Systems Japan
Security and reporting, including business intelligence tools, are adequate.
Cloud Consultant at i-Community AG
NinjaOne should consider adding notifications about script executions to email, Teams, or Slack channels.
DevOps Engineer at a tech services company with 201-500 employees
The ability to have more than one NinjaOne agent on a device at a time, as this is a significant issue in our current state.

Setup Cost

Microsoft Defender Vulnerability Management provides economical tiered pricing with P1 and P2 options, often included in existing bundles.
NinjaOne offers competitive, device-specific monthly pricing with good value, affordable compared to competitors, and benefits for educational institutions.
Overall, every organization wishes for cheaper options, but we look at the security side as well, so we are good for now.
Senior Cloud Security Consultant at MetLife
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
The pricing for NinjaOne is appropriate for small companies.

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.
Not Joseph Pearson - PeerSpot reviewer
Assistant Vice President, Tech Solutions at LPL Financials
Has simplified remote software delivery and script management but needs improved reporting flexibility and better Mac support
NinjaOne's best features include ease of use regarding enablement and deployment, a broad selection and ability of software enablement, and API deliveries. Using CrowdStrike, we are able to tie in NinjaOne's API to have these automatically deliver to endpoints upon addition of those devices to a group with that policy deployed to it. NinjaOne has positively impacted our organization by making delivery easier for our end users and improving the ability to create scripts, manage scripts, and check status of devices and their compliance. This easier delivery with NinjaOne gives us oversight on devices without having to be on the call or remoted in directly to a device.
