CST VerdictBased on our analysis of available product data, here is our conclusion:
AWS security teams testing Cognito deployments should use Cognito Scanner because it catches account enumeration and privilege escalation flaws that managed AWS security tools routinely miss. At 109 GitHub stars with zero cost, it's the only tool built specifically to attack Cognito's auth mechanics rather than treating identity as a checkbox in a broader AWS scanner. Skip this if your threat model doesn't include internal or compromised-credential scenarios; Cognito Scanner assumes attackers already have network access and focuses on what they can do once inside.
