Abnormal Security Security Posture Management vs iam-lint: Side-by-Side Comparison (2026)

Abnormal Security Security Posture Management

Mid-market and enterprise security teams drowning in Microsoft 365 misconfigurations will cut remediation time in half with Abnormal Security Security Posture Management, because it actually tells you how to fix things instead of just flagging them. The tool covers the full NIST ID and PR control families for access and asset management, and its AI-driven risk scoring surfaces the admin account drift and overly permissive app grants that matter most. Skip this if your environment is multi-cloud heavy; it's Microsoft 365-only, so hybrid shops will still need a separate CSPM for AWS or Azure IaaS.

iam-lint

Teams automating IAM policy review in CI/CD pipelines will get real value from iam-lint because it catches overpermissioned policies before they reach AWS, not after deployment. The tool runs free as a GitHub action with configurable severity rules, making it practical for squads that want shift-left IAM governance without licensing friction. Skip this if your organization needs centralized policy enforcement across multiple cloud providers or dynamic entitlement review; iam-lint is AWS-only and static-analysis-only, best suited to developers who own their own IAM definitions.
