An IAM (Identity and Access Management) Analyzer in cloud security is a specialized tool that reviews and evaluates user permissions, roles, and policies across cloud environments to identify over-privileged accounts, misconfigurations, and potential security risks. It helps organizations gain deep visibility into who has access to what, how they got that access, and whether that access is necessary. By analyzing IAM policies, role hierarchies, and access patterns, the tool detects deviations from the principle of least privilege and flags excessive or unused permissions. This improves security posture, supports compliance with standards like SOC 2, ISO 27001, and HIPAA, and reduces the risk of insider threats or privilege escalation attacks in dynamic cloud infrastructures like AWS, Azure, or Google Cloud.
