About ExeQuantum
High level explanation of what we do, how we do it
ExeQuantum delivers Post-Quantum Cryptography as a Service (PQCaaS), an API-driven platform that enables governments, enterprises, and critical infrastructure providers to integrate quantum-safe cryptography into their systems seamlessly, regardless of framework, programming language, or deployment environment.
What we do
Our mission is to absorb the complexity of PQC, rapidly evolving standards, algorithm selection, and heavy computation, and provide organizations with a ready-to-integrate, sovereign-aligned solution that maintains long-term security and compliance.
How It Works
At its core, PQCaaS provides secure Key Encapsulation Mechanisms (KEMs) and digital signatures (DSAs) through simple API endpoints. This allows your systems to establish quantum-safe keys and shared secrets for secure communication without needing in-house expertise in cryptography.
Key Generation: Clients call our API to generate public/private key pairs and associated certificates.
Key Exchange: Counterparties use the API to encapsulate and exchange shared secrets using public keys.
Decapsulation: Recipients use the API to decapsulate and establish symmetric encryption keys.
This process abstracts away the underlying algorithms (ML-KEM, ML-DSA, HQC, FN-DSA, SLH-DSA, etc.) while ensuring future-proof interoperability.
Deployment Options
ExeQuantum is API-driven but deployment-flexible:
On-Premise / Sovereign Cloud: For regulated environments, our platform can be deployed fully within national infrastructure, operated by your teams or accredited local partners.
ExeQuantum Cloud: For faster adoption, clients can use our secure hosted service.
Hybrid Mode: Combine local key storage with ExeQuantum’s orchestration layer to balance sovereignty and efficiency.
This ensures organizations retain control and sovereignty over their cryptographic operations while benefiting from ExeQuantum’s updates and orchestration.
Agility in Practice
By integrating PQCaaS, organizations no longer need to track evolving standards or manually re-engineer systems as algorithms are retired or replaced. Our orchestration layer handles:
Continuous alignment with NIST PQC standards.
Updates and patches to emerging algorithms.
Backwards compatibility for legacy systems.
This means you can deploy once, and remain agile as standards evolve.
Security and Compliance
ExeQuantum does not store client private keys, secrets, or signatures. Data sovereignty, privacy, and compliance are preserved:
Privacy: Only you control your keys and encrypted data.
Security: Even in the event of a breach on our side, no cryptographic material is accessible to attackers.
Compliance: Our architecture aligns with ISO27001, GDPR, HIPAA, PCI DSS, APRA CPS230, and local regulatory frameworks such as Saudi NCA guidelines.
Important Considerations
PQCaaS is not a replacement for holistic cybersecurity. It addresses the cryptographic layer of your defenses. Clients must continue to follow sound security practices, including proper key management, token protection, and fallback planning for service availability.
ExeQuantum provides enterprise-grade redundancy, anti-DDoS measures, and robust failover capabilities, but integration design should always include resiliency best practices.
