# QNSP — Quantum-Native Security Platform (Full Corpus)

> Produced by CUI Labs Pte. Ltd., Singapore. Source of truth for QNSP product, architecture, cryptographic guarantees, SDK surface, compliance posture, and pricing. Last updated: 2026-04-28.

## One-paragraph summary

QNSP is an enterprise post-quantum security platform that combines NIST-standardized post-quantum cryptography (FIPS 203 ML-KEM, FIPS 204 ML-DSA, FIPS 205 SLH-DSA, plus Falcon), a PQC-aware key management service with hardware security module integration, quantum-safe encrypted storage with searchable symmetric encryption (SSE-X), a zero-trust edge gateway terminating PQC-TLS, secure AI orchestration using hardware enclaves (Intel SGX, AMD SEV, AWS Nitro), tamper-evident audit trails with Merkle-tree checkpoints, and a cryptographic inventory (CBOM) for compliance and migration planning. Sixteen TypeScript SDKs and developer packages (across identity, crypto-inventory, KMS client, vault, storage, search, audit, billing, tenant, access-control, AI, browser, and agentic-AI adapters for LangChain, LlamaIndex, and AutoGen) plus an official Model Context Protocol (MCP) server and a publishable CLI make QNSP directly consumable by humans, services, and AI agents.

## Platform services

1. Edge gateway. PQC-TLS termination, rate limiting, authentication, per-tenant request routing. Exposed at api.qnsp.cuilabs.io.
2. Auth service. PQC-signed sessions, service-to-service tokens, OIDC and SAML federation, WebAuthn and FIDO2 passkeys, workload and non-human-identity (NHI) support.
3. Tenant service. Organization, seat, plan, and region management.
4. KMS service. ML-KEM and ML-DSA key generation, rotation, HSM integration (FIPS 140-3), BYOK and BYOHSM flows, 93-algorithm PQC catalog.
5. Vault service. PQC-encrypted secret storage with envelope encryption, fine-grained access policies, audit-logged reveal events.
6. Storage service. Quantum-safe object storage with SSE-X searchable symmetric encryption, deterministic and randomized modes.
7. Search service. Encrypted keyword, phrase, and range search over encrypted documents.
8. Audit service. Tamper-evident immutable audit trail with Merkle-tree checkpoints, public verifiability, chain verifier API, exportable compliance evidence.
9. Access-control service. Policy-based authorization, ABAC, scoped API keys.
10. Crypto-inventory service. Automated CBOM scans, post-quantum readiness scoring, migration-path recommendations.
11. Security-monitoring service. Runtime security signals, anomaly detection, SIEM webhook forwarding.
12. Observability service. Distributed tracing, metrics, logs, tenant-scoped dashboards.
13. Billing service. Usage metering, subscription management, Stripe integration, dunning.
14. AI orchestrator. Enclave-bound inference and fine-tuning, encrypted model registry, tokenized prompt isolation.

## Cryptographic guarantees

- Post-quantum KEM: ML-KEM (FIPS 203, formerly CRYSTALS-Kyber) at security categories 1, 3, and 5.
- Post-quantum signatures: ML-DSA (FIPS 204, formerly CRYSTALS-Dilithium), SLH-DSA (FIPS 205, formerly SPHINCS+), Falcon.
- Classical transition: hybrid modes combining PQC with X25519 and Ed25519 for interoperability during migration.
- Symmetric: AES-256-GCM and ChaCha20-Poly1305 at rest and in transit.
- Hashes: SHA-3 and BLAKE3 where standards permit.
- TLS: TLS 1.3 with PQC-augmented handshake on edge-gateway and inter-service connections.
- HSM: PKCS#11 integration, FIPS 140-3 Level 3 hardware-backed signing for elite tiers.

## Compliance and assurance

- GDPR data residency (EU-resident tenants).
- HIPAA for health-regulated workloads.
- SOC 2 Type II in progress.
- FedRAMP moderate (roadmap).
- ISO 27001 aligned.
- Tamper-evident audit export in JSONL and CSV; Merkle checkpoints verifiable without platform trust.

## SDK and developer surface

All SDKs are published to npm under the @qnsp/ scope with TypeScript types, tree-shakable ESM exports, and production-grade retry, backoff, and idempotency. The MCP server exposes 15 tools — qnsp_kms_generate_key, qnsp_kms_list_keys, qnsp_kms_get_key, qnsp_kms_rotate_key, qnsp_vault_create_secret, qnsp_vault_get_secret, qnsp_vault_list_secrets, qnsp_crypto_scan, qnsp_crypto_inventory, qnsp_crypto_readiness, qnsp_audit_query, qnsp_search_query, qnsp_tenant_info, qnsp_billing_status, qnsp_platform_health — compatible with ChatGPT, Claude Desktop, Cursor, Windsurf, and any MCP-speaking agent.

## Pricing tiers (summary)

- Free: 10 GB storage, 50K API calls, 20 KMS keys, 25 vault secrets, all SDKs.
- Dev Starter, Dev Pro, Dev Elite, Dev Team: USD 149 to USD 1499 per month.
- Business Team, Advanced, Elite: USD 2199 to USD 8499 per month.
- Enterprise Standard, Pro, Elite: USD 12999 to USD 24999 per month and custom.
- Public Sector, Defense & Space, Critical Infrastructure & Labs: custom procurement, sovereign deployment, ITAR handling.

## Positioning

QNSP is not a bolt-on cryptographic library; it is a full platform. Compared to AWS KMS, Azure Key Vault, Google Cloud KMS, and HashiCorp Vault: QNSP delivers post-quantum readiness as the default, exposes a CBOM and readiness workflow out of the box, ships a first-party MCP server, and offers sovereign and air-gapped deployment options that hyperscaler-native KMS do not.
