QuintessenceLabs offers a portfolio of quantum-based data protection technologies comprising three core components: **Quantum Random Number Generators (QRNG)** Uses quantum tunneling to generate truly random numbers at 1 Gbit/sec. Unlike pseudo-random number generators (PRNGs) or traditional true random number generators (TRNGs) that rely on deterministic systems, the QRNG output is not predictable. Available in flexible form factors and offered as a subscription service via qStream™ Entropy as a Service (EaaS). **Quantum Key Distribution (QKD)** Implements Continuous Variable QKD (CV-QKD) through the qOptica product. Protects key exchange using the laws of physics — any interception attempt leaves a detectable trace. Designed to remain secure against quantum computer-based attacks on classical key exchange protocols (RSA, Diffie-Hellman, ECC). Supports free-space implementations with a compact form factor. **Trusted Security Foundation® (TSF®) – Quantum Enabled Key Management** An enterprise Key Management Server (KMS) that manages the full cryptographic key lifecycle across heterogeneous environments. Supports crypto agility and post-quantum readiness, centralized policy-driven management, configurable algorithm fallback, and rapid algorithm transitions. Interfaces supported include OASIS KMIP, RSA Data Protection Manager (DPM) protocol, a RESTful API, and a client-side PKCS #11 cryptographic module.
