Which AWS service provides on-demand, self-service access to AWS compliance and security control reports?

AWS Artifact provides on-demand access to AWS security and compliance reports and select online agreements. This service is crucial for demonstrating compliance to auditors and stakeholders. AWS Config is a service that enables you to assess, audit, and evaluate the configurations of your AWS resources, but it doesn't provide compliance reports directly. Amazon GuardDuty is a threat detection service that continuously monitors for malicious activity and unauthorized behavior, not a report repository. AWS Trusted Advisor provides recommendations to help you follow AWS best practices in five categories: cost optimization, performance, security, fault tolerance, and service limits, but it does not offer compliance reports like SOC or ISO.
