Tiresias is a zero-trust policy enforcement point you run yourself. What you buy here is the install licence your install verifies offline. Priced per governed tenant, never per seat, and Community is a $0 rung of the same ladder rather than a separate thing: it issues a real licence, it just costs nothing.
The whole deny path, self-hosted, up to five governed tenants.
$0
Up to twenty-five governed tenants, with the analyst surface.
$750
Up to one hundred governed tenants on one install.
$2,500
Unlimited governed tenants.
$7,500
Unlimited governed tenants, administered as child tenants.

Policy enforcement, injection screening, SIEM forwarding and the signed audit trail run at every tier, licensed or not. A lapsed licence makes the proxy smaller, never more permissive. The last row is the ceiling each rung buys. It is a fence, not a meter: it stops an evaluation quietly becoming a production estate, and the top two rungs have none because what they sell is the contract and child-tenant administration. Canonical price book: tiresias-zt docs/design/price-book.md.
Once a version carries a support window it receives fixes while it is the current minor version or the one before it, and for 12 months from its release date, of which the final 3 months are security fixes only. A new minor version is never published less than six months after the previous one, which is what keeps those 12 months honest.
The window starts at the first Tiresias 1.x, which is not published yet. Every Tiresias version published so far is a 0.x and is outside it. Your purchase entitles you to every version published during your paid term, including the first one that carries the window.
