Auth0 FGA provides managed relationship-based authorization built on OpenFGA. A comparison with Permit.io covering policy languages, deployment models, and enterprise features.

OPA vs OpenFGA vs Cedar: comparing policy engines for fine-grained authorization. Strengths, trade-offs, and use cases of OPA, OpenFGA, and Cedar for scalable access control.

OpenFGA alternatives for fine-grained authorization including SpiceDB, Cerbos, OPA, Cedar, and Permit.io. A comparison of relationship-based and policy-based approaches to help you choose.

WorkOS FGA extends RBAC with hierarchical resource scoping. A comparison with Permit.io covering policy languages, deployment models, and when each fits your authorization requirements.

Map enforcement, granularity, realtime, and audit to APP 1.7 homework: inventory PEPs, PI→resource maps, revoke/sync, and audit/export for privacy-policy statements.

APP 1.7-1.9 commence 10 December 2026. Honest ADM privacy-policy disclosure needs AuthZ inventory, PI→resource maps, PEPs, realtime revoke, and decision-log evidence, plus a soft APRA parallel.

EN 18286:2026 is Europe's first harmonised standard under the EU AI Act. It turns Article 17's QMS requirements into auditable processes. Here's what it means for teams shipping AI agents.

Cheat-sheet: NIST NCCoE's four focus areas (identification, authorization, access delegation, and logging) mapped to concrete AuthZ controls. Soft alignment aid, not a certification checklist.

Treat AI agents as privileged NHIs: distinct identity, least privilege, attributable delegation, and forensic decision logs, not shared keys. Map to NIST NCCoE's identification · authorization · delegation · logging.

Permit.io vs Cerbos, plus Cerbos alternatives: both run an open source policy decision point next to your app. Managed control plane vs self-hosted PDP, with a table and when to choose each.

For human-to-agent delegation, bind human principal, agent ID, tools, data, policy decision, and HITL, not just tool traces, into an attributable audit trail.

Oso Cloud acquired by Tiny (announced Oct 6, 2026), most of the team joined Temporal. A practical guide to Oso alternatives, mapping Polar to RBAC, ReBAC and ABAC, and migration planning.
