Sovereign Deployment
Sovereign & Air-Gap
Sovereign means you control the infrastructure, the keys, and the evidence. Stella Ops runs without mandatory external dependencies and produces verifiable proof for every release decision.
What sovereign-ready means
Self-hosted control plane
No forced SaaS dependency. Deploy the entire suite on your infrastructure — on-premises, private cloud, or air-gapped network.
Air-gap / offline-first operations
Vulnerability feeds and verification data move via signed bundles. Core decisions stay offline; nothing leaves the network unless you manually opt in to telemetry.
Bring your own keys
Customer controls trust anchors. Pluggable crypto profiles support your signing and verification infrastructure.
Regional crypto profiles
Plugin architecture for compliance-driven cryptography. FIPS-140-3, GOST R 34.10, SM2/SM3, or eIDAS-qualified signatures.
Deterministic replay
Same inputs produce identical outputs. Auditors can verify decisions offline months later with frozen feeds and manifests.
Exportable evidence
Decision Capsules package evidence for audit — not scattered across logs. Portable, verifiable, independent of Stella infrastructure.
Auditable core (source-available)
The suite is source-available (BUSL-1.1). Evidence formats and verification tooling are open source (Apache-2.0). Auditors can verify decisions independently — no vendor lock-in for trust.
Local intel aggregator
Run your own CVE + VEX intelligence service. Aggregate sources, dedupe, snapshot, and sign — all inside your boundary.
Crypto profiles
Stella supports pluggable cryptographic profiles for regional compliance and organizational requirements.
| Profile | Algorithms | Use case |
|---|---|---|
| default | ECDSA P-256, SHA-256 | Standard deployments |
| fips-140-3 | ECDSA P-384, SHA-384 | US federal / FedRAMP |
| gost | GOST R 34.10-2012, Streebog | CIS region compliance |
| sm | SM2, SM3 | Chinese standards |
| eidas | RSA-PSS, ECDSA (QES) | EU qualified signatures |
Deployment modes
Connected mode
Standard deployment with optional feed updates from public sources.
- → Live vulnerability feed sync (NVD, OSV, vendor advisories)
- → Opt-in telemetry for fleet analytics (disabled by default)
- → Automated signature verification
Air-gapped mode
Fully isolated deployment for regulated or sensitive environments with no outbound traffic unless telemetry is manually enabled.
- → Signed feed bundles imported via sneakernet or DMZ relay
- → Zero external network dependencies
- → Customer-controlled update cadence
