Sentiment score
7.8
Microsoft Defender for Cloud is highly scalable, managing diverse environments smoothly, with seamless integration and flexible subscriptions despite cost concerns.
AKS offers excellent scalability due to its adaptation from Kubernetes.
We are using infrastructure as a code, so we do not have any scalability issues with Microsoft Defender for Cloud implementation because our cloud automatically does it.
It has multiple licenses and features, covering infrastructures from a hundred to five hundred virtual machines, without any issues.
Defender won't replace our endpoint XDR, but it will likely adapt and support any growth in the Microsoft Cloud space.
 

Stability Issues

Azure Kubernetes Service is stable, self-healing, with occasional sync issues, and concerns typically arise from external factors.
Sentiment score
7.7
Microsoft Defender for Cloud provides a stable, reliable environment with minor performance issues primarily due to outdated systems.
From my usage, I would rate its stability as eight to nine out of ten.
Defender's stability has been flawless for us.
Microsoft Defender for Cloud is very stable.
Microsoft sometimes changes settings or configurations without transparency.
 

Room For Improvement

AKS requires faster alerts, better support, improved cost-efficiency, enhanced UI, streamlined integration, security, monitoring, and simplified deployment.
Microsoft Defender for Cloud needs better automation, integration, user-friendliness, documentation, pricing, real-time monitoring, and legacy support.
The costs are rising rapidly, and we have not seen any cost reductions by moving to Azure.
It is costly compared to other solutions such as Canonical.
Microsoft, in general, could significantly improve its communication and support.
It would be beneficial to streamline recommendations to avoid unnecessary alerts and to refine the severity of alerts based on specific environments or environmental attributes.
The artificial intelligence features could be expanded to allow the system to autonomously manage security issues without needing intervention from admins.
 

Setup Cost

Azure Kubernetes Service is costly, with potential $10,000 monthly fees, but offers flexible pricing and valued platform flexibility.
Microsoft Defender for Cloud provides flexible pricing with a free version; costs vary by features, region, and enterprise needs.
Transitioning to Azure did not bring cost reductions; in fact, costs are rising rapidly.
The pricing for Azure Kubernetes Service seems to be around the average, which I would rate as a five out of ten.
Every time we consider expanding usage, we carefully evaluate the necessity due to cost concerns.
We appreciate the licensing approach based on employee count rather than a big enterprise license.
Microsoft Defender for Cloud is pricey, especially for Kubernetes clusters.

Professional services boost confidence but pricing and user-friendliness need attention
We have multiple solutions such as SimpliVity, Nutanix, and DXRail, which are all part of our Ansible-based system. It gives us more confidence and we can control our groups effectively. The solution is not particularly user-friendly for novice administrators, making it challenging to understand certain aspects. Templates are not readily available, requiring users to build their own worksheets and everything from scratch. This is a main decentralization we observe compared to VMware. We have tested various solutions including Rancher, RHEL, Canonical from SUSE, and the bare metal version from RHEL direct. Since pricing is not a major concern, we chose the best fit for our application, which was specifically designed for this particular platform.
Vibhor Goel - PeerSpot reviewer
A single tool for complete visibility and addressing security gaps
Currently, issues are structured in Microsoft Defender for Cloud at severity levels of high, critical, or warning, but these severity levels are not always right. For example, Microsoft might consider a port being open as critical, but that might not be the case for our company. Similarly, it might suggest closing some management ports, but you might need them to be able to log in, so the severity levels for certain things can be improved. Even though Microsoft Defender for Cloud provides a way to temporarily disable certain alerts or notifications without affecting our security score, it would be better to have more granularized control over these recommendations. Currently, we cannot even disable certain alerts or notifications. There should be an automated mechanism to design Azure policies based on the recommendations, possibly with AI integration. Instead of an engineer having to write a policy to fix security gaps, which is very time-consuming, there should be an inbuilt capability to auto-remediate everything and have proper control in place. Additionally, enabling Defender for Cloud at the resource group level, rather than only at the subscription level, would be beneficial.
