Compare governance, identity, and compliance services across AWS, Azure, and GCP including IAM, policy enforcement, configuration management, audit logging, and use cases.
Recommendation: AWS is recommended for enterprises requiring the most comprehensive compliance automation with 300+ managed Config rules and pre-built conformance packs for regulated industries. Azure excels for Microsoft-centric organizations leveraging Entra ID for unified identity, PIM for just-in-time privileged access, and Azure Arc for hybrid and multi-cloud governance. GCP is ideal for teams wanting ML-driven least-privilege automation via IAM Recommender and simple declarative governance constraints through Organization Policy Service.

AWS provides the most mature governance toolchain with IAM for identity and access management, Config for resource compliance, and Organizations for multi-account governance at scale.
AWS IAM enables fine-grained access control with users, groups, roles, and policies. IAM Identity Center (formerly SSO) provides centralized workforce access management across multiple AWS accounts and business applications. Supports attribute-based access control (ABAC) for dynamic, scalable permissions.
AWS Config continuously monitors and records resource configurations, enabling compliance auditing with 300+ managed rules. Config Conformance Packs bundle rules for standards like CIS, PCI DSS, and HIPAA. Automatic remediation via Systems Manager fixes non-compliant resources.
AWS Organizations provides centralized governance across multiple accounts with Service Control Policies (SCPs) enforcing guardrails. AWS Control Tower automates multi-account setup with pre-configured governance blueprints, landing zones, and detective guardrails powered by Config rules.
