One user is easy to govern. A thousand users across fifty teams is hard—unless your governance system understands organizational structure.
Policy inheritance makes enterprise AI governance manageable.
Without inheritance, you’d need:
Zentinelle organizes governance hierarchically:
Organization
├── Policy: "No PII in prompts"
├── Policy: "GPT-4 only"
│
├── Engineering
│ ├── Policy: "Can use CodeLlama"
│ ├── Backend Team
│ │ └── User: Alice (inherits all above)
│ └── Frontend Team
│ └── User: Bob (inherits all above)
│
└── Marketing
├── Policy: "Claude preferred"
└── User: Carol (inherits org + marketing)
Policies flow down. Set once, apply everywhere.
Model permissions: Which AI models can be used
Content policies: What content is allowed/blocked
Data access: Which data sources are available
Tool permissions: What tools/actions are permitted
Rate limits: Usage caps and quotas
Budget limits: Spending controls
Lower levels can specialize but not violate:
Allowed:
Not allowed:
Stricter is OK. Looser requires parent change.
Regulated industries: Org-level compliance policies inherited by everyone.
Cost management: Org budget split to team budgets split to user budgets.
Model governance: Approved models at org level, team-specific preferences below.
Data access: General data access org-wide, sensitive data restricted to specific teams.
With inheritance:
Add new user: Assign to team → automatically gets all applicable policies
Update org policy: Change once → applies to everyone
Create new team: Inherits org defaults → add team-specific policies
Audit compliance: Check policy chain → see exactly what applies to any user
Setting up policy inheritance:
Governance that scales.
