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. Identity teams managing hybrid AD and Entra ID environments need Forest Druid because it maps Tier 0 attack paths that other tools treat as invisible, and it costs nothing to deploy. The tool identifies excessive privileges and ownership relationships across both forests simultaneously, catching lateral movement routes that pure cloud-native identity tools or on-prem AD auditors typically miss. Skip this if your organization runs cloud-only identities without legacy Active Directory; the value concentrates in hybrid complexity, not greenfield Entra ID shops.
