Comparison
QNSP vs QuSecure QuProtect
An honest, code-grounded side-by-side. QuSecure is a credible crypto-agility pioneer with real government and telecom deployments. QuProtect is a software-only orchestration overlay: it installs an agent on endpoints and upgrades existing TLS / IPSec sessions to hybrid post-quantum tunnels, and inventories your crypto. QNSP operates a level down — the managed platform that actually holds and runs the keys, secrets, encrypted storage, and audit chain. Every row below is backed by a verifiable public source — qusecure.com pages, named press, or QNSP source files at github.com/cuilabs/qnsp-public.
The key question is what each product operates. QuProtect orchestrates crypto-agility on top of infrastructure you already run — upgrading sessions in transit to hybrid ML-KEM tunnels and giving you a live cryptographic inventory. QNSP is the infrastructure underneath: managed PQC KMS, vault, SSE-X storage, encrypted search, and a tamper-evident audit chain, with 90 algorithms, dual-provider cross-verification, enforced crypto-policy tiers, and public NIST ACVP evidence. They can overlap on discovery and policy; they diverge sharply on whether the product actually holds and operates the keys and data.
Side by side
Twelve categories that matter to a PQC buyer
| Category | QNSP | QuSecure QuProtect |
|---|---|---|
| Layer of the stack | Full managed PQC platform — KMS, quantum-safe vault, SSE-X encrypted storage, encrypted search, AI orchestration, audit chain, and crypto-policy enforcement, delivered as a hosted multi-tenant service. QNSP holds and operates the keys, secrets, and ciphertext on your behalf. | Software-only crypto-agility orchestration overlay. QuProtect installs an agent on endpoints and routes traffic through an orchestration layer that upgrades existing TLS / IPSec sessions to hybrid post-quantum tunnels — sitting on top of, not replacing, the customer's existing crypto infrastructure. Source: qusecure.com/post-quantum-cryptography. |
| What it operates | KMS key generation, rotation, wrap / unwrap, BYOK import; PQC-encrypted vault with versioning; SSE-X encrypted object storage; encrypted vector search; tamper-evident audit ledger. The platform is the system of record for the keys and ciphertext. | Per QuSecure's public materials, QuProtect manages cryptographic protocol selection and the in-transit upgrade to PQC; it does not appear to operate its own dedicated KMS, secret vault, or encrypted-storage service. The customer's existing key stores and data systems remain in place underneath the overlay. |
| Primary value delivered | A quantum-safe place to put your keys, secrets, and data — operated end to end, with PQC as the default, not a mode you switch on. | Crypto-agility: 'swap out a vulnerable algorithm' and push cryptographic policy across the network from one control plane, without code changes or downtime. Genuinely valuable for upgrading large legacy estates in transit. Source: qusecure.com. |
| Public PQC algorithm coverage | 90 algorithms across 14 PQC families (27 KEMs + 63 signatures): ML-KEM, ML-DSA, SLH-DSA, FN-DSA / Falcon, HQC, BIKE, Classic McEliece, FrodoKEM, NTRU, NTRU-Prime, MAYO, CROSS, UOV, SNOVA. Independently reproducible from the public mirror at github.com/cuilabs/qnsp-public. | Supports the NIST-standardized set — ML-KEM (FIPS 203), ML-DSA (FIPS 204), SLH-DSA (FIPS 205), with FN-DSA / Falcon and HQC noted as under evaluation. In its published telecom deployment, traffic is upgraded to TLS 1.3 with hybrid X25519 + ML-KEM-768. Source: qusecure.com/post-quantum-cryptography, MWC telecom case study. |
| Crypto inventory (CBOM) | Crypto Inventory / CBOM service auto-discovers cryptographic assets, scores NIST PQC readiness, and produces phased migration plans across an 11-provider multi-cloud estate, with the findings feeding the audit chain. | QuProtect Recon delivers a live, automated inventory of cryptographic assets across the network — a real CBOM capability and a legitimate QuSecure strength. The inventory is paired with the orchestration overlay rather than a managed key / storage platform. Source: qusecure.com. |
| In-transit vs at-rest protection | Quantum-safe at rest and in transit: vault and SSE-X storage hold payload material under PQC envelope encryption (ML-KEM-768 by default, ML-KEM-1024 on the maximum tier) — the bytes on disk are quantum-safe, not only the bytes on the wire. | Focused on the session layer: upgrading TLS / IPSec handshakes to hybrid post-quantum tunnels. This hardens data in transit against harvest-now-decrypt-later on the wire; protection of data at rest depends on the customer's underlying storage and key systems, which the overlay does not itself encrypt. |
| Dual-provider cross-verification | On Maximum and Government policy tiers every crypto operation is signed by one provider (liboqs, native C) and verified by a second, independent provider (noble, pure JS) — 18 NIST-finalized algorithms overlap. A single-implementation bug is caught at runtime, with provider attestation in the audit ledger. | Not publicly documented on qusecure.com. We are not asserting QuSecure lacks internal verification — only that a published two-independent-implementation runtime cross-verification model is specific to QNSP's platform. |
| Enforceable crypto-policy tiers | Four hard-enforced tiers (default / strict / maximum / government) with per-tenant algorithm allow-lists enforced at the edge gateway, KMS, and vault. Government tier enforces FIPS-finalized-only (FIPS 203/204/205), no draft standards, HSM-protected root keys. | QuProtect's core strength is pushing cryptographic policy changes across a network from a single control plane — orchestrated policy applied to sessions. A per-tenant, hard-guardrailed policy-tier model attached to managed KMS / vault operations is QNSP's framing rather than a documented QuProtect capability. Source: qusecure.com. |
| Verifiable conformance evidence | Public, reproducible NIST ACVP conformance at qnsp.cuilabs.io/verify/conformance: noble 435/435 across FIPS 203/204/205 and liboqs 240/240 ML-KEM, with a published evidence digest. Anyone can re-run the sandbox — no signup. | QuProtect provides a CBOM to support compliance with NIST, FIPS, and GDPR. A public self-serve, re-runnable NIST ACVP conformance harness equivalent to QNSP's /verify/conformance is not part of the published QuSecure materials. Source: qusecure.com. |
| Deployment + distribution | Hosted multi-tenant SaaS reachable via api.qnsp.cuilabs.io, plus VPC, on-prem, and air-gapped topologies. Self-serve signup; SDKs in 5 languages on public registries. | Software-only overlay that deploys onto existing infrastructure without forklift hardware changes. Available via the AWS Marketplace and through partners including Accenture, Dell, Cisco, and Carahsoft; specific pricing is not published publicly. Source: qusecure.com, businesswire.com. |
| Funding + scale | Singapore-based startup (CUI Labs Pte. Ltd.); public benchmarks and a transparent SDK mirror. Built to be the auditable managed PQC platform. | U.S.-based crypto-agility pioneer. Raised a $28M Series A (including an additional close led by Two Bear Capital with Accenture Ventures participation). Public customer references include the U.S. Army and Air Force, plus telecom, energy, and financial-sector deployments. Source: securityweek.com, businesswire.com, crunchbase.com. |
| Open + auditable | Full public SDK + integration mirror at github.com/cuilabs/qnsp-public; SDKs on npm, PyPI, pkg.go.dev, crates.io, and Maven Central. Every claim on this page is independently reproducible. | QuSecure publishes case studies, product pages, and press, but as a commercial software-only platform it does not provide a public mirror of the full product equivalent to QNSP's qnsp-public repo. |
When to pick which
Honest decision guide
Pick QuSecure if…
- Your priority is upgrading a large legacy estate's TLS / IPSec sessions to hybrid post-quantum in transit, without touching application code or swapping hardware.
- You want a single control plane to push algorithm and policy changes across the network, plus a live cryptographic inventory of what you have today.
- You are buying through the AWS Marketplace or a partner (Accenture, Dell, Cisco, Carahsoft) and value QuSecure's government / telecom deployment references.
Pick QNSP if…
- You need a managed platform that actually operates keys, secrets, encrypted storage, and a tamper-evident audit chain — quantum-safe at rest, not only in transit.
- You want PQC algorithm breadth beyond the in-transit set, with dual-provider cross-verification and public NIST ACVP evidence you can re-run yourself.
- You want enforced per-tenant crypto-policy tiers, transparent self-serve pricing, a free tier, and a multi-language SDK reachable through an API today.
Use both if…
- QuProtect orchestrates the in-transit migration and inventory across your existing network, while QNSP provides the quantum-safe key management, vault, storage, and audit chain that the protected sessions ultimately talk to — the overlay and the platform live at different layers and complement each other.
