Andromeda Security Rightsize Your Permissions for Human Users + NHI vs IAMSpy: Side-by-Side Comparison (2026)

Andromeda Security Rightsize Your Permissions for Human Users + NHI

Mid-market and enterprise security teams drowning in permission creep across cloud IAM will see immediate value in Andromeda Security Rightsize Your Permissions for Human Users + NHI because it surfaces what's actually being used versus what's been granted, then tells you exactly which roles to shrink. The tool covers both human and non-human identities in a single inventory, which matters since most teams manage these separately and miss half their attack surface. This is not the right fit if you need real-time access enforcement or need to audit on-premises directory services; Andromeda is cloud-native permission analysis, not a replacement for PAM orchestration.

IAMSpy

Security engineers auditing AWS IAM policies will find IAMSpy's Z3 prover approach uniquely valuable for catching logical permission contradictions that manual review misses, especially in complex multi-policy scenarios. The tool is free and already in use across 222 GitHub stars worth of deployments, lowering adoption friction for teams already comfortable with CLI-based analysis. Skip this if your organization needs a UI-driven governance platform or real-time policy enforcement; IAMSpy is for practitioners who want to query and validate, not manage identity lifecycle at scale.
