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 replacing SMS OTP with something actually resistant to SIM swaps will find Shush Network Authentication worth the deployment effort. It eliminates the user friction that kills adoption of traditional MFA by authenticating silently through carrier network data instead of app prompts or codes, and the SIM-to-device duration checks catch the swap attacks that SMS cannot. Skip this if your organization needs authentication to work across international roaming scenarios or requires deep integration with existing identity platforms; Shush's MNO-dependent model has real geographic constraints.
