Why ExeQuantum?
As hyperscalers introduce basic post-quantum primitives, organizations with national sovereignty mandates, enterprise obligations, or long-horizon compliance requirements demand more than vendor-managed encryption. ExeQuantum delivers sovereign cryptographic control — blending hybrid algorithm resilience, jurisdictional deployment, entropy transparency, and long-term assurance.
How ExeQuantum Compares Across Deployment Models
| Factor | ExeQuantum | In-House | Consulting | Open Source | Hyperscaler PQC Offerings |
|---|---|---|---|---|---|
| Deployment Speed | Controlled rollout; rapid orchestration | 6–18 months internal build | 3–6 months engagement | Varies; high integration overhead | Instant vendor-side activation |
| Cost Structure | Predictable licensing with ongoing control | High staffing & infra costs | Expensive billable hours | Low upfront, high long-term maintenance | Low marginal, fully vendor-bundled pricing |
| Security Control | Client-owned keys, entropy visibility, algorithm flexibility | Complex governance; requires ongoing auditing | Third-party reliant; limited accountability | Self-maintained; no SLA-backed security guarantees | Vendor-controlled black box; zero client visibility |
| Sovereignty Assurance | Full jurisdictional separation; client-governed key custody | Internal but limited cross-border enforceability | Limited contractual protections | Undefined jurisdictional protection | Foreign jurisdiction exposure; Cloud Act applicable |
| Cryptographic Resilience | Multi-primitives hybrid (lattice, code-based, hash-based, QRNG-enhanced) | Resource-dependent, often limited to one primitive | Dependent on vendor specialization | Community-dependent, no proactive hybridization | Fixed vendor roadmap (NIST lattice only) |
