description: >-
  Censys uses a tiered subscription model spanning a Free Community account, a self-serve
  Individual tier (from $100), and two custom-priced enterprise tiers (Security Operations,
  Threat Hunting). Quotas surface as per-query result caps, Collections limits, and host-data
  history windows. Higher tiers add Censys-Threat-Dataset, on-demand scanning, CensEye, RBAC,
  and SSO/SAML. Volume and multi-year contracts are negotiated through sales.
