AWS unified security dashboard that aggregates security alerts from multiple services. Like having a central command center that shows all security issues in one place.
Security teams use Security Hub to get a complete view of their security posture across all AWS services.
All four provide a centralized view of cloud security posture and findings. AWS Security Hub aggregates findings from AWS services and partners and maps them to standards; Azure Defender for Cloud and GCP Security Command Center provide similar posture management and alert aggregation for their platforms; OCI Cloud Guard focuses on detecting misconfigurations and risky activity in OCI.
