Sentiment score
8.2
Palo Alto Networks VM-Series is highly regarded for stability, reliable performance, and consistent uptime, despite minor navigation delays.
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.

Hardware is generally very stable.
Security Technical Lead at a tech services company with 11-50 employees
I have not experienced any major problems or downtime.

Room For Improvement

Microsoft Defender Vulnerability Management needs enhanced accuracy, better integration, user-friendliness, cost-effectiveness, and improved platform management and reporting.
Palo Alto Networks VM-Series needs UI updates, better platform integration, scalability, user-friendliness, and improved documentation for broader efficiency.
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.

Security Specialist at Prudential Systems Japan
Integration with CSIRT across all use levels would make it easier for administrators to stay updated on the blocked entities without manual intervention.
Cyber security consultant at L&T Technology Services
Most customers go for partner-enabled support, which involves multiple layers, leading to delays.
Security Technical Lead at a tech services company with 11-50 employees
Having those features missing, we are not proposing Palo Alto Networks VM-Series to all customers.
Sr. Network Engineer at a tech services company with 1-10 employees
 

Setup Cost

Enterprise users report mixed views on Microsoft Defender's pricing, noting competitive rates, but caution significant costs without discounts.
Palo Alto VM-Series is costly but reliable, with complex licensing; AWS Marketplace offers scalable subscription options.
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
Palo Alto is expensive in terms of pricing, particularly when comparing features to cost.
Security Technical Lead at a tech services company with 11-50 employees
The cost involves purchasing through a vendor, which might mark up due to the supply chain.
Senior IT Infrastructure Specialist at contemi
Pricing for Palo Alto Networks is higher than other OEMs, but considering the robustness and features, it gains customer trust.
Head of Sales at Omgea Exim Ltd
 

Valuable Features

Microsoft Defender provides compliance, integration, threat identification, accurate assessments, and streamlined management for enhanced security and efficient vulnerability handling.
The VM-Series provides scalable, flexible security with advanced threat management, visibility, and integration features, enhancing network protection.
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.
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.

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.
Senior Cloud Security Consultant at MetLife
We use these tools to prevent all known and unknown threats using Palo Alto Networks' Wildfire and other data filtering tools to gather information, analyze traffic, manage malicious traffic, and offer visibility, control, and attack prevention.

Featured Reviews

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.
AV
Cyber security consultant at L&T Technology Services
Enhance cybersecurity for large enterprises using advanced threat management
An improvement could be the integration of security intelligence with Palo Alto cloud via APIs. This would allow IOCs, domains, and hash values to be automatically entered, reducing manual entry. Integration with CSIRT across all use levels would make it easier for administrators to stay updated on the blocked entities without manual intervention.
