Stop Access Sprawl Before It Becomes a Breach

Modern applications create millions of access relationships between users, teams, resources, and AI agents. AuthZed provides centralized authorization, instant revocation, and complete visibility into who can access what.

Trusted by organizations building planet-scale authorization.

Millions of relationships. One source of truth. Users & Teams AI Agents Resources Orgs & Projects AuthZed centralized authorization strongly consistent Apps APIs & Services Search & Lists AI / RAG Change one relationship — every app, API, and agent enforces it the same way, instantly.
What we solve

Top Security Challenges We Solve

Prevent Excessive Access

Reduce standing privileges by enforcing least-privilege access dynamically.

Instant Revocation

When access is removed, permissions disappear immediately across all applications and services.

Eliminate Authorization Drift

Replace inconsistent authorization logic scattered across hundreds of services with a single source of truth.

Secure AI Agents

Ensure AI agents can only access data their users are authorized to see.

Simplify Audits

Answer in seconds instead of days:

  • Who can access this resource?
  • Why do they have access?
  • How was access granted?
The race condition most systems miss

The New Enemy Problem — and how SpiceDB prevents it

A subtle but dangerous authorization bug, first described in Google's Zanzibar paper. It strikes when a permission change and a content change are applied out of order — or when a check runs against a stale snapshot of access. The result: a user you just removed can still reach data they were never meant to see.

The setup ① Alice removes Bob from a confidential folder. ② Alice adds a new sensitive document to that folder. WITHOUT strong consistency Check Bob's access…against an OLD snapshot ALLOW Bob — the “new enemy” — reads the secret ✗ WITH SpiceDB + ZedTokens Check at a revision≥ the removal (ZedToken) DENY Revocation always wins — no stale-read leak ✓ Every write returns a ZedToken capturing that point in time; reads can demand a snapshot at least as fresh as the change.

For your security team this means no race conditions that quietly re-grant access, and revocation you can actually trust — the foundation of Zero Trust authorization at scale.

Zero Trust Authorization

Make every request prove authorization regardless of network location.

Mergers & Acquisitions

Rapidly onboard and offboard entire organizations without rebuilding role structures.

Third-Party & Vendor Access

Grant temporary access that automatically expires.

AI Governance

Prevent AI copilots and agents from accessing sensitive data outside their authorization scope.

Key Security Features

Built for security from the ground up

Explainability

Answer “Why does this user have access?” with a complete relationship chain.

Expiring Relationships

Grant temporary access that automatically expires.

Consistent Enforcement

The same authorization decision is used across APIs, applications, agents, and services.

Auditability

Track how permissions are granted through users, groups, organizations, projects, and delegated access.

High Availability

Authorization remains available even for mission-critical applications.
