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
5.5
Calculating Armis ROI is difficult, offering risk mitigation and inventory management benefits with no clear cost reduction evidence.
Sentiment score
4.9
Determining ROI for Microsoft Defender Vulnerability Management is challenging due to service bundling and mixed-use of other products.
Organizations typically do not rely solely on Microsoft products to avoid putting all eggs in one basket, which presents a challenge for maximizing ROI.
Cloud Security Engineer at a computer software company with 51-200 employees
As a Microsoft partner, we receive significant discounts, making the solution affordable for us.
COO at Floating-Dot Technology LTD
 

Customer Service

Sentiment score
7.7
Armis customer service is generally satisfactory, with timely technical support and proactive onboarding appreciated by most users.
Sentiment score
6.6
Microsoft Defender's support is praised for expertise but criticized for communication delays and varying service quality.
I have not faced challenges with Armis support, as pre-sales engineers have been helpful.
Technical Specialist at Truvisor
I would rate it ten out of ten.
Director /Founder at Touchstone Machine Tap
They are sometimes responsive, however, often issues cannot be reproduced on their end, making it challenging.
Security Specialist at Prudential Systems Japan
The support we receive from Microsoft is declining, and for example, after taking advanced support, we have not received satisfactory answers.
Microsoft Solutions Manager at Self-Employed
They are familiar with Microsoft products but are not direct Microsoft staff, which is an area needing improvement.

Scalability Issues

Sentiment score
7.5
Armis is a scalable SaaS platform popular for its adaptability and efficiency, beneficial to cybersecurity and SOC analysts.
Sentiment score
7.6
Microsoft Defender excels in scalability and integration but faces documentation and on-premise infrastructure challenges across industries.
As a SaaS platform, it is highly scalable.
Sr. Engineer at Zensar Technologies
It is very scalable and easy to scale, as I also rated it eight on a scale of one to ten.
Technology And Digitization Lead at JLL
The integration is straightforward for those who understand it, though documentation needs improvement.
Cloud Security Engineer at a computer software company with 51-200 employees
It is scalable; I evaluated the product and decided to use Defender on over 700 of our company servers.

Stability Issues

Sentiment score
8.4
Armis is praised for stability, with high ratings despite minor bugs, and users appreciate its support and performance.
Sentiment score
6.6
Microsoft Defender Vulnerability Management is highly stable and reliable, with minimal downtime, despite minor resource-related and compatibility issues.
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

Armis struggles with integration, stability, high costs, and lacks intelligence, especially impacting Azure, AWS, and GCP users.
Microsoft Defender needs better false positive reduction, integration, cost management, risk scoring, and documentation for small enterprises.
Armis cannot be used as a standalone solution and should be integrated with other solutions.
Technical Specialist at Truvisor
It misses out on a lot of vulnerabilities.
Technology And Digitization Lead at JLL
Armis could improve its marketing campaigns across regions.
Director /Founder at Touchstone Machine Tap
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
 

Setup Cost

Armis pricing is generally seen as reasonable and competitive, with straightforward licensing but mixed opinions on cost-effectiveness.
Microsoft Defender Vulnerability Management provides economical tiered pricing with P1 and P2 options, often included in existing bundles.
Armis pricing is average, neither cheaper nor more expensive than other solutions.
Director /Founder at Touchstone Machine Tap
The pricing and licensing of the product are average, and I rate it six out of ten.
Technology And Digitization Lead at JLL
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

Armis is very easy to implement due to its agentless design and offers a granular level of visibility for all assets in the network.

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.

Technology And Digitization Lead at JLL
Comprehensive asset visibility and OT operations support enhance risk mitigation
I use Armis for asset discovery and vulnerability assessments of the OT network Armis is easy to use. Very few software solutions have OT capabilities that do not impact OT operations. Its asset visibility is good as well. This comprehensive feature set is crucial for our operations.…
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.
