CST VerdictShort answer
Mid-market and enterprise teams managing fine-grained access across microservices and APIs should pick Aserto for its 1ms authorization latency, which makes it viable for real-time decision-making without degrading application performance. The tool's support for relationship-based access control (ReBAC) via a Zanzibar-inspired directory gives you the modeling flexibility that RBAC and ABAC alone cannot provide for complex permission hierarchies. Skip this if your organization is early-stage and still consolidating identity providers; Aserto assumes mature directory integrations and demands policy-as-code discipline that smaller teams may not yet need. AWS teams managing credential sprawl without dedicated IAM governance tooling should deploy AWS Lambda - IAM Access Key Disabler; it solves the specific problem of orphaned access keys staying active indefinitely by automating enforcement of key rotation policies at zero cost. The function runs natively on Lambda with no additional infrastructure or licensing, making it practical for teams that lack budget for commercial IAM lifecycle tools. Skip this if you need centralized policy reporting across multiple cloud providers or fine-grained exceptions workflows; this is automation for rotation enforcement, not a policy management platform.
