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. Teams running signup flows or fraud prevention systems that need to block disposable email registrations will find value in Disposable Email Domains because it's maintained, free, and covers 1,363 known domains across major providers. The list updates regularly on GitHub and integrates into most identity verification pipelines with minimal friction. Skip this if you're looking for behavioral signals or account takeover detection; this tool does one thing,block throwaway addresses,and doesn't pretend to do more.
