CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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 already paying for the platform should use IAM Identity Center to eliminate a separate identity vendor; the free pricing makes it a no-brainer for workforce SSO across native AWS applications and approved SaaS integrations. Native integration with AWS Organizations and support for SAML 2.0 means you're not fighting connector drift or license tiers. Skip this if you need rich attribute-based access control, fine-grained entitlement management across on-premises systems, or pre-built connectors to hundreds of SaaS apps; it's built for AWS-first shops, not enterprises running Okta-scale identity complexity across hybrid infrastructure.
