Microsoft Defender for Cloud
Score 8.5 out of 10

Microsoft Defender for Cloud is a Cloud Security Posture Management (CSPM) and Cloud Workload Protection Platform (CWPP) for Azure, on-premises, and multicloud (Amazon AWS and Google GCP) resources.
In a multi-account/multi-tenant environment, GuardDuty often alerts us to possible malicious traffic before it becomes an issue. The ability to automatically enable GuardDuty creates baseline security which is crucial when an account is first created. It also helps greatly in environments where other users are able to create resources as often GuardDuty alerts us to insecure resources we did not know about. It can however sometimes be a little overzealous with its assessments alerting on benign activity which then requires suppression rules.
If you need to proceed with pay as you go service then go ahead with Microsoft Defender for Cloud. This could be expensive in the long run but if the organization usage is slightly less than then this would suite the purpose. Also, it has the latest threat updates, so you're future proof in terms of potential treats.
Automation is crucial to managing sprawl and the additional complexity that comes with it. SOC management workbooks and process automation give significant flexibility.
The Security posture score and Security Alerts are neatly centralized and offer me crucial information quickly.
Defender for Cloud avoids the common compromise of simplicity for completeness (former Azure Security Center). The security warnings and advice go into great detail while remaining current and useful.
UI/UX. It can get a little messy when navigating around with all the flyouts in the Azure portal which can be frustrating, particularly when under time pressure.
The query languages for the queries and workbooks are another language that needs to be learned - it would be nice to have kept it closer to T-SQL or something like that to minimize the need to learn new syntax.
Adding cost estimations to the security recommendations would really improve the experience.
It is a great product that integrates nicely when running an Azure platform and even multi-cloud environment. Not looking for point-solutions but a suite that answers most requirements. It is very comfortable being able to use KQL, workbooks and automation that is native to the azure platform
I believe Microsoft Defender for Cloud stacks up well against the other tools we looked at. It is native to the Azure platform and provides the same insights as the other tools. We selected Microsoft Defender for Cloud because it integrates well with the Azure resources and gives the needed insight, security alerts and recommendations.
