Features, pricing, ratings, and pros & cons — compared head-to-head.
Aserto is a commercial access management tool by Aserto. Duo Passport is a commercial access management tool by Duo Security. Compare features, ratings, integrations, and community reviews side by side to find the best access management fit for your security stack.
Based 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.
Mid-market and enterprise teams tired of authentication friction will find real value in Duo Passport's invisible authentication model, which eliminates repeated MFA prompts through continuous trust evaluation rather than point-in-time challenges. The tool's support for passwordless authentication, device memory, and cross-platform session sharing (Windows, macOS, browsers, desktop apps) means fewer login interruptions without sacrificing security posture. Skip this if your organization needs granular passwordless deployment control or deep integration with legacy on-premises identity systems; Passport prioritizes frictionless access over the configurability some enterprises demand.
