Honest coverage
What Tallin governs, and what it doesn't.
Each person, application, and autonomous agent carries one of four coverage labels: observed, inferred, enforced, or not covered. Tallin governs the AI routed through it, and tells you plainly what falls outside. No false certainty.

Coverage in practice
Know exactly where your AI record is strong or incomplete.
Coverage is a live map of what each source can support. Tallin keeps direct observations, inferences, enforced controls, and unobserved gaps separate, then shows which sources are healthy, stale, degraded, or missing.
- Read the state, not a blended scoreKeep observed, inferred, enforced, and not covered distinct.
- See stale or degraded sourcesExpose recency and source health before a report relies on them.
- Move gaps into actionGive every uncovered actor or source a clear next step.
Coverage taxonomy
One honest language for the state of every AI actor.
The four states keep finance, security, legal, and platform teams reading the same map: which AI actors Tallin is actively governing, which it can only observe, and where the real gaps remain.
- OBSERVED
- Observed: directly captured through gateway events, provider usage APIs, provider admin APIs, or authoritative telemetry, attributed to the AI actor behind it, whether a human, an app, or an agent.
- INFERRED
- Inferred: likely usage from billing, expense, SSO, network, CSV, or discovery evidence.
- ENFORCED
- Enforced: actively governed in the request path (an owner, an approved model scope, a budget with an automatic cutoff, a policy, and an off switch for the actor) plus access restriction, SSO, CASB, or provider admin policy.
- NOT COVERED
- Not covered: anything outside the AI Tallin routes: direct provider calls made outside Tallin, and tool / MCP execution side effects. We report these as explicit gaps, never silenced, so the picture stays honest.
