Security

How your data is handled.

Guardrail Ledger is part of Spot Suite, operated by Spot Cloud B.V. Each customer runs in a dedicated Customer Environment with read-only Azure collectors, Microsoft Entra sign-in, and audit logging throughout.

  • Microsoft Entra SSO

    Sign-in runs through Spot Suite OIDC with Microsoft Entra. No separate username or password database is maintained by Guardrail Ledger.

  • Dedicated Customer Environment

    Each customer gets an isolated deployment — its own Cloudflare Worker, D1 database, and storage. Your ledger data does not share infrastructure with other tenants.

  • Tenant-scoped access

    All scan results, exception records, and audit packs are scoped to your Customer Environment. Cross-tenant data access is not part of the product model.

  • EU data residency

    Data is processed and stored under Spot Cloud B.V. with EU data residency for scan results, ledger records, and monthly audit packs in Cloudflare R2.

  • Audit logging

    Admin and user actions inside Guardrail Ledger are logged so you can trace who viewed, approved, or exported records.

  • Read-only Azure collectors

    Collectors read Azure Policy, exemptions, RBAC, and tags. Nothing is written back to your Azure subscriptions.
