Coverage

Honest coverage beats false certainty.

Tallin treats coverage as a product feature. Every important total should show how much is known, inferred, enforced, or still outside the map.

Signal taxonomy

Give every buyer the same language for AI evidence.

Coverage labels keep finance, security, legal, and operators aligned about what the company can prove and what remains a gap.

Observed: directly captured through gateway events, provider usage APIs, provider admin APIs, or authoritative telemetry.
Inferred: likely usage from billing, expense, SSO, network, CSV, or discovery evidence.
Enforced: controlled through gateway policy, tenant restriction, SSO, CASB, or provider admin policy.
Not covered: a path Tallin cannot yet measure reliably, such as off-network personal-device usage.

Why it matters

Most AI governance failures start with a dashboard that quietly mixes measured usage with guesses. Tallin keeps those states visible so leaders can act without pretending the picture is complete.

Start with an honest ledger.

Create a workspace, connect the first provider signals, and see what is observed, inferred, enforced, and not covered.
