Featured Reviews

Daniel Wichinescki - PeerSpot reviewer
IT Specialist | SRE | Cloud Public and Private at Parana Banco
Has supported production deployments and simplified permission management though could reduce monitoring costs
For Azure Kubernetes Service (AKS), we only used it to orchestrate the Kubernetes pods. We didn't use the other features. We only used the environment to start our application. I utilized the automatic scaling capabilities. The integration with Azure Active Directory helped with the security of our applications. I think Amazon EKS is better. EKS is the best because there are many features to use for scaling and to control the environments.
AS
Manager at Softcell Technologies Limited
Improved multi-cloud security posture and compliance reporting but still need better alert tuning
The multi-cloud support in Microsoft Defender for Cloud is good, but the Azure integrations are much deeper than AWS or GCP, so feature consistency could improve. Alert noise and recommendation prioritization can become overwhelming in large environments without significant tuning. I would also prefer better custom reporting, dashboard flexibility, and simpler policy exceptions management for enterprise-scale operations. The portal experience in Microsoft Defender for Cloud can feel fragmented because some investigations move between Microsoft Defender for Cloud, Defender XDR, Azure Policy, and Sentinel. Integration with DevOps or security pipelines is good, but onboarding and tuning Kubernetes or container security still requires strong expert expertise. I would also prefer more intuitive recommendation and remediation guidance and clear workflows for large multi-subscription environments.
