Security / Architecture

Isolation, data boundaries, and failure domains.

Abon is built as a tenant-safe control plane. We isolate data, constrain blast radius, and make every service observable and recoverable.

01

Tenancy and isolation

Control-plane first, per-tenant data domains.

Hard tenant boundaries

Logical isolation at the data layer; no cross-tenant joins. Isolation verified in tests and observability.

Data segregation

Scoped services

Multi-tenant services run with tenant-scoped credentials and per-tenant encryption context.

Scoped credentials

No shared state assumptions

Caches, queues, and search indices are tenant-aware; fan-out fan-in with guardrails.

Safe by design

02

Reliability and failure domains

We bias to graceful degradation.

Bounded blast radius

Per-tenant circuit breakers and rate limits prevent noisy neighbors.

Resilient pipelines

Idempotent ingest, retries with backoff, and dead-letter handling keep data consistent.

Health and rollback

Health probes, versioned deployments, and fast rollback paths reduce exposure time.

03

Data handling

Clear ownership and retention posture.

  • Encryption in transit and at rest; secrets managed centrally.
  • PII minimization and scoped access for support.
  • Retention aligned to customer agreements with explicit deletion paths.
  • Audit logging on access, configuration changes, and permission edits.

04

Observability

Know when something drifts.

  • Per-tenant metrics and alerts on ingest, dispatch, proof, and billing events.
  • Structured logs with tenant IDs and correlation IDs for traceability.
  • Synthetic checks across critical journeys (intake → dispatch → proof → billing).
