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

"The features of Microsoft Defender for Cloud that I appreciate the most are automation and event detection."
"Microsoft Defender for Cloud helps in improving our overall security posture. We have a nice overview of what is missing where and what can be improved."
"The integration with Logic Apps allows for automated responses to incidents."
"The most valuable features are the monitoring of users, endpoint detection and response, and the adaptability of the AI threat intelligence engine, which quickly adapts to customizations."
"The most valuable feature for me is the variety of APIs available."
"Everything is built into Azure, and if we go for cross-cloud development with Azure Arc, we can use most of the features. While it's possible to deploy and convert third-party applications, it is difficult to maintain, whereas Azure deployments to the cloud are always easier. Also, Microsoft is a big company, so they always provide enough support, and we trust the Microsoft brand."
"It offers virus management and addresses threats such as viruses, worms, spyware, and other critical security concerns."
"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."
"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 documentation and implementation guides could be improved."
"Microsoft does a fairly good job, but many products are developed from an engineer's perspective rather than the end user perspective, making the intuitive flow of the interface sometimes less than optimal."
"We haven't experienced issues with Microsoft Defender for Cloud for our company size of about five hundred people. However, I've heard there might be issues with scalability for larger enterprises."
"Microsoft Defender for Cloud is pricey, especially for Kubernetes clusters. It could be cheaper."
"The remediation process could be improved."
"Azure is a complex solution. You have so many moving parts."
"You cannot create custom use cases."
"The solution could improve by being more intuitive and easier to use requiring less technical knowledge."
"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

"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."
"Pricing is difficult because each license has its own metrics and cost."
"This is a worldwide service and depending on the country, there will be different prices."
"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."
"I am not involved in this area. However, I believe its price is okay because even small customers are using Azure Security Center. I don't think it is very expensive."
"Currently, Microsoft offers only one plan at the enterprise level which is $15 per machine."
"Understanding the costs of cloud services can be complicated at first. As with a lot of things in the cloud, it can be quite hard to understand the end cost, but it becomes clearer over time. Early on, the lack of transparency is a challenge. Microsoft does not tell you the cost when they launch something. It is clever marketing, and there is room for improvement there. There should be clarity from the start."
