STAC in Practice: How We Built Deployable Cryptographic Sovereignty

The STAC Doctrine
Earlier this year, ExeQuantum published the STAC doctrine, a framework for security infrastructure built on Sovereignty, Transparency, Agility, and Compliance.

The response was clear: people resonated with the values. But they also had a question.

“How do you implement STAC?”

Not as a whiteboard dream. Not as a vague roadmap. But in real systems, under real regulatory scrutiny, with real cryptographic risk on the line.

Today, we’re answering that with the release of the STAC Technical White Paper, a 30-page breakdown of the cryptographic, operational, and compliance architecture behind STAC.

Sovereignty: More Than On-Premise

Most vendors equate sovereignty with on-premise deployment. That’s necessary, but not sufficient.

Our implementation of STAC enables:
‍
  • Sovereign entropy sources (QRNG, CRNG, fully verifiable)
    ‍
  • Key ownership at every layer (root, session, ephemeral)Geopolitical leverage: From Russia’s GOST standards to China’s SM algorithms, cryptography is increasingly seen as a strategic asset, not just a technical tool.
    ‍
  • Jurisdiction-respecting deployments, including air-gapped, embedded, or edge models
    ‍
  • Local partner deliver, to ensure full deployment and integration pipeline is sovereign
This isn’t a checkbox. It’s a provable architecture.

Transparency: Trust Through Auditability

Security doesn’t come from NDAs or hand-waving. STAC demands transparency through:
‍
  • CBOMs (Cryptographic Bills of Materials) - auto-generated, version-tracked, audit-synced
    ‍
  • Jasmin-based cryptographic implementations - with constant-time, memory-safe guarantees
    ‍
  • Audit logs that are tamper-evident and signed
    ‍
  • /compliance endpoints - mapped to ISO, NIST, IRAP, and more
You don’t have to “trust” that your keys are safe. You can see how they were generated, when they rotated, and what entropy was used.

Agility: Zero Downtime, Full Control

STAC doesn’t just work in static environments, it evolves:
‍
  • Seamless cryptographic upgrades via versioned APIs
    ‍
  • Canary rollouts and rollback logicTrust-building by openness: NIST’s post-quantum cryptography competition was deliberately international, involving researchers from Europe, Asia, and beyond, to counter suspicion of unilateral control.
    ‍
  • Multi-algorithm hybrid models (e.g., ML-KEM + x25519)
    ‍
  • Edge and IoT-compatible primitives
Whether it’s TLS, VPNs, embedded devices, or blockchain wallets, ExeQuantum ensures STAC travels with you.

Compliance: Built-In, Not Bolted On

Every ExeQuantum deployment surfaces compliance-ready data by design.
‍
  • Mapped alignment with ISO/IEC, NIST SP 800–208, GDPR, IRAP, PCI-DSS, FHIR, and more
    ‍
  • API endpoints for real-time evidence collection
    ‍
  • Webhook-ready audit pipelines
    ‍
  • Sector-specific modules for banking, healthcare, identity, telco, and critical infrastructure
The compliance burden doesn’t land on your dev team, it’s already coded in.

Why This Matters Now

PQC is going to be mandatory, but how it’s deployed will determine whether we avoid the next trust collapse.

STAC is our answer. Not a philosophy, but a codebase. Not a future goal, but a live system already in use.

We invite regulators, engineers, architects, and operators to read the technical white paper, challenge it, adopt it, build on it. Because in 2025, trust isn’t claimed. It’s provable.
