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. Mid-market and enterprise security teams deploying AI agents at scale will find Keycard's value in ephemeral credentials and task-based policies, which eliminate the static identity sprawl that makes agent access control a nightmare. SOC2 compliance plus federated authorization with real-time edge enforcement covers the PR.AA and DE.CM requirements most teams actually care about when shipping agents to production. Skip this if you need a universal workforce IAM platform; Keycard is deliberately agent-first and won't replace your employee SSO layer.
