Cloud security has cut investigation time and now reveals threats faster but needs simpler oversight
When deploying AI applications, my key security concerns with Microsoft Defender for Cloud are data loss, leakage of data, and guardrails around the actual AI, and I am hoping that this is going to help me put those guardrails in place and identify data exfiltration. Microsoft Defender for Cloud has not helped me manage and secure multi-cloud environments, as we are 100 percent Microsoft and have not really got it in any other environment at all. I am not yet using the unified AI-powered security feature offered by Microsoft Defender for Cloud, but that is coming. I am not yet using the integrated XDR feature of Microsoft Defender for Cloud, but that is coming. I am not yet utilizing the GenAI threat protection features of Microsoft Defender for Cloud. That is also coming and a lot of that will come from learning it here. I have enabled the agentless scanning in my cloud environment with Microsoft Defender for Cloud. Assessing the impact on my workload protection without needing to install agents with Microsoft Defender for Cloud makes it a lot easier, but it also identifies a lot more, which puts more load on me sometimes. I would advise another organization considering Microsoft Defender for Cloud that it is the most logical route to follow if their whole ecosystem is Microsoft. It is easy to implement and it is very self-explanatory when doing it, making sense to just follow the steps as it is too simple, really. I would rate this review a 7.5 out of 10.

Centralized security testing has improved vulnerability remediation and compliance reporting
I recommend more enhancements focusing on penetration testing for both SSL over HTTP and non-SSL over HTTP, specifically targeting the RCP Rich Client Platform and Equinox frameworks that allow on-premises desktop applications to be tested simultaneously. I believe those would significantly improve the tool in the future. I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities. Once we build this installer—rather than just working on the codebase—sometimes, we face gaps considering the build parameters and conversions to the installer. Identifying those gaps is an area that could use improvement after the installer or desktop application testing, which would be beneficial. That is the only reason; otherwise, I could easily rate it a ten out of ten given its smooth operational process.

Quotes from Members

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

Pros

"It helps you to identify the gaps in your solution and remediate them, and it produces a compliance checklist against known standards such as ISO 27001, HIPAA, iTrust, etc."
"For any type of service, I would recommend the go-to solution for security on Azure is Security Center."
"One important security feature is the incident alerts. Now, with all these cyberattacks, there are a lot of incident alerts that get triggered. It is very difficult to keep monitoring everything automatically, instead our organization is utilizing the automated use case that we get from Microsoft. That has helped bring down the manual work for a lot of things."
"The valuable features include the ability to manage devices and the fact that Defender can replace other security tools like SCCM."
"We can create alerts that trigger if there is any malicious activity happening in the workflow and these alerts can be retrieved using the query language."
"With respect to improving our security posture, it helps us to understand where we are in terms of compliance. We can easily know when we are below the standard because of the scores it calculates."
"I've seen benefits since implementing Microsoft Defender for Cloud. It's easy to manage for our large organization as an endpoint security solution. It integrates well with Office 365 and Windows 11, which is better than before. Patching, updates, and threat protection are all handled together now. Its AI features help predict threats."
"The features that Azure Security Center provides from a security point of view are amazing."
"I think the best features that Nucleus Security offers are purely the faster remediation to dev tools, which is crucial for managing, prioritizing, and fixing vulnerabilities while helping operational pipelines run these vulnerability management tools."
"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

"The product must improve its UI."
"Support needs to be highly responsive, especially in large enterprise environments."
"After getting a recommendation, it takes time for the solution to refresh properly to show that the problem has been eliminated."
"The documentation and implementation guides could be improved."
"While we are satisfied with Defender for Cloud's features, an AI enhancement could potentially provide better advice and adapt more effectively to our environment."
"From a compliance standpoint, they can include some more metrics and some specific compliances such as GDPR."
"To improve Microsoft Defender for Cloud, I think pricing-wise, the license price is a little bit higher from an ingestion cost perspective."
"Most of the time, when we log into the support, we don't get a chance to interact with Microsoft employees directly, except having it go to outsource employees of Microsoft. The initial interaction has not been that great because outsourced companies cannot provide the kind of quality or technical expertise that we look for. We have a technical manager from Microsoft, but they are kind of average unless we make noise and ask them to escalate. We then can get the right people and the right solution, but it definitely takes time."
"Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow."
"I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities."
 

Pricing and Cost Advice

"We are using the free version of the Azure Security Center."
"They have a free version, but the license for this one isn't too high. It's free to start with, and you're charged for using it beyond 30 days. Some other pieces of Defender are charged based on usage, so you will be charged more for a high volume of transactions. I believe Defender for Cloud is a daily charge based on Azure's App Service Pricing."
"Azure Defender is definitely pricey, but their competitors cost about the same. For example, a Palo Alto solution is the same price per endpoint, but the ground strikes cost a bit more than Azure Defender. Still, it's pricey for a company like ours. Maybe well-established organizations can afford it, but it might be too costly for a startup."
"Our clients complain about the cost of Microsoft Defender for Cloud."
"Pricing depends on your workload size, but it is very cheap. If you're talking about virtual machines, it is $5 or something for each machine, which is minimal. If you go for some agent-based solution for every virtual machine, then you need to pay the same thing or more than that. For an on-premises solution like this, we were paying around $30 to $50 based on size. With Defender, Microsoft doesn't bother about the size. You pay based on the number of machines. So, if you have 10 virtual machines, and 10 virtual machines are being monitored, you are paying based on that rather than the size of the virtual machine. Thus, you are paying for the number of units rather than paying for the size of your units."
"Although I am outside of the discussion on budget and costing, I can say that the importance of security provided by this solution is of such importance that whatever the cost is, it is not a factor."
"The pricing model for most plans is generally good, but the cost of the new Defender for Storage plan is high and should be revisited, as it could lead to disabling desirable security features due to cost."
"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."
