# Defense — Solution

> Apinizer for defense and aerospace — air-gapped or sovereign clusters, strict change control, zero-trust assumptions. Trusted by Havelsan.

*Solutions · Defense & Aerospace*

## API governance for the systems that can't fail.

Air-gapped clusters, sovereign deployment, and zero-trust assumptions are not a tier — they're the default. Apinizer runs without external dependencies, with rootless containers and an audit trail you can present to oversight.

## What this solves

### Air-gapped, sovereign, no calls home

The Worker carries no telemetry calls. The Manager carries no hidden cloud dependency. Container images are rootless. Deployment is the cluster you already operate.

### Change control by manifest

APIops manifests reference everything by name. Diff-friendly in a repo, reviewable by oversight, idempotent on apply. The deploy that lands is the one approval signed off on.

### Zero-trust, by design

Three-tier permission model (System / Project / Team), audit at the persistence layer, mTLS everywhere, and standardized error surfaces — without bolt-on security middleware.

### Multi-protocol surface

HTTP, gRPC, SOAP, WebSocket, GraphQL — with the same policy, audit, and observability stack. No second runtime to certify.

## Compliance

- **ISO 27001** — Information security management
- **NIST 800-53** — Security controls alignment
- **Air-gap deployment** — No external network dependencies
- **Rootless containers** — Reduced privilege footprint
- **KVKK** — Personal data protection alignment

## Customer story

**Havelsan** — Defense & aerospace

> Apinizer runs where the cluster doesn't talk to the outside world — and it still gives us the audit trail oversight expects.

**Outcome:** Sovereign deployment with full audit and federated identity for the platform team.
