Topaz · FinOps Profile

Topaz Finops

FinOps view of Topaz spend. Topaz is open source (Apache-2.0) and free to self-host - in that model there is no vendor invoice, and cost is the compute, memory, and storage for running the authorizer (often as a sidecar) plus the embedded directory. Because the authorizer runs local to your applications, the dominant cost drivers are replica count and directory size rather than per-decision charges. The optional Aserto hosted control plane (a separate commercial product built on Topaz) is where any subscription/usage spend lives: central policy and directory management, decision logs, and real-time sync to deployed authorizers. Aserto per-unit rates are not reconciled here.
