With Azure Policy, organizations can establish rules to ensure that deployed resources meet organizational and regulatory standards, including naming conventions, allowed regions, security settings, and resource configurations. Policies can audit existing resources, block non-compliant deployments, and automatically generate compliance reports across subscriptions and resource groups. This allows administrators to identify and remediate issues proactively, reducing risk and ensuring consistency across the cloud environment.
By automating governance, Azure Policy reduces the likelihood of human error and helps maintain regulatory compliance, security, and operational consistency. It integrates seamlessly with other Azure services, providing organizations with visibility into their compliance posture and actionable insights for enforcing standards across all resources.
For these reasons, Azure Policy is the correct choice for managing governance and compliance in Azure environments. It enables organizations to enforce consistent rules, prevent non-compliant configurations, and streamline compliance reporting, ensuring that resources are deployed and maintained according to organizational and regulatory requirements.
