Brings together cloud security insights through a unified view and supports agentless protection for virtual machines
Copilot and similar features are already being used, though not necessarily for Microsoft Defender for Cloud specifically. We are trying to get more experience before rolling out most of Microsoft Defender for Cloud's AI capabilities. This is definitely on our to-do list, and the priority is urgent as we seek to learn more about these capabilities. The GenAI threat protection from Microsoft Defender for Cloud has not been enabled yet. There are many unknowns with AI applications. AI agents will operate while you're not present, whether you are sleeping or awake, and it's unclear whether there would be any exfiltration of data or how data is being managed. Microsoft Purview is being used extensively, and there is significant development going on with DSPM that will be rolled out to address security concerns. Data labeling and proper demarcation for sensitivity of data before it is received are being actively pursued.

Improved radiation safety and compliance has supported patient care but daily workflows still need refinement
I think it can be improved by making it more practical, integrated, and easier for teams to apply in real-world workflow from a healthcare perspective. The main improvements I can see right now are better user training with real-case scenarios rather than only theory, and clear and simple protocols for day-to-day operations. Strong integration between safety compliance and documentation systems would help significantly in practice for the healthcare field, which is a niche field. The biggest gain would come from making security processes easier to follow consistently, especially in busy environments where teams need to be aware of clarity and really need to rely on the documentation they are using.I chose a rating of seven because it offers strong value in safety, risk reduction, and compliance, especially in healthcare. However, there is still room for improvement in usability and day-to-day integration. Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Some of the most valuable features of Microsoft Defender for Cloud include its effectiveness in threat detection through unsupervised machine learning, CTI, and advanced sandboxing."
"It's quite a good product. It helps to understand the infections and issues you are facing."
"Defender for Cloud provides a prioritized list of remediations for security issues, reducing risk and improving security operations."
"The most valuable feature is the regulatory compliance aspect, where we utilize predefined initiatives like NIST."
"The feature of Microsoft Defender for Cloud that I have found most valuable is the alerts, which are pretty standard for security."
"I would rate Microsoft Defender for Cloud a nine out of 10."
"The main feature is the security posture assessment through the security score. I find that to be very helpful because it gives us guidance on what needs to be secured and recommendations on how to secure the workloads that have been onboarded."
"Defender is a robust platform for dealing with many kinds of threats. We're protected from various threats, like viruses. Attacks can be easily minimized with this solution defending our infrastructure."
"We have seen clear compliance and risk control outcomes more than other operational metrics, including fewer process gaps during documentation and safety checks, strong consistency in following protocols for handling, traceability, and staff awareness, better audit readiness, a lower chance of procedure errors, and faster escalation when something appears out of standard, which is very important for us in the healthcare sector."
 

Cons

"I would like to see more connectors and plugins with other platforms."
"An area where Microsoft Defender for Cloud could be improved is in getting away from having multiple menus that do the same thing, which seems imposing when looking at it."
"No possibility to write or edit any capability."
"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."
"Microsoft Defender for Cloud could be improved by adding capabilities for NetApp files and more PaaS resources from other vendors, not just Microsoft."
"The solution is quite complex. A lot of the different policies that actually get applied don't pertain to every client. If you need to have something open for a client application to work, then you get dinged for having a port open or having an older version of TLS available."
"One of the main challenges that we have been facing with Azure Security Center is the cost. The costs are really a complex calculation, e.g., to calculate the monthly costs. Azure is calculating on an hourly basis for use of the resource. Because of this, we found it really complex to promote what will be our costs for the next couple of months. I think if Azure could reduce the complex calculation and come up with straightforward cost mapping that would be very useful from a product point of view."
"The product must improve its UI."
"Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow."
 

Pricing and Cost Advice

"The pricing is very difficult because every type of Defender for Cloud has its own metrics and pricing. If you have Cloud for Key Vault, the pricing is different than it is for storage. Every type has its own pricing list and rules."
"The product's pricing policy is generally favorable."
"Currently, Microsoft offers only one plan at the enterprise level which is $15 per machine."
"I rate Microsoft Defender a three out of ten for affordability. The price could be a little lower."
"This solution is more cost-effective than some competing products. My understanding is that it is based on the number of integrations that you have, so if you have fewer subscriptions then you pay less for the service."
"The price of the solution is good for the features we receive and there is an additional cost for Microsoft premier support. However, some of my potential customers have found it to be expensive and have gone on to choose another solution."
"Azure Defender is a bit pricey. The price could be lower."
"The licensing is straightforward but can become expensive if you cover everything. You must balance the cost against the importance of what needs covering."
