# QuintessenceLabs Product Portfolio QuintessenceLabs Product Portfolio is a Quantum Key Distribution & QRNG product by QuintessenceLabs. It runs in the cloud or on-premises (hybrid). Pricing is commercial (contact sales). Quantum-enabled portfolio for key mgmt, QKD, QRNG, and data protection. Checked October 2026. ## What is QuintessenceLabs Product Portfolio? QuintessenceLabs offers a portfolio of quantum-enabled cryptographic security products spanning key management, quantum key distribution, random number generation, and data protection. **Trusted Security Foundation (TSF):** A centralized, vendor-neutral encryption key management solution supporting Post-Quantum Cryptography (PQC) crypto-agile key management with the latest NIST quantum-resistant algorithms. Common Criteria Certified. **qOptica 100 QKD:** A continuous variable quantum key distribution (CV-QKD) system that uses specialized hardware to share secret keys over an optical point-to-point link, with secrecy guaranteed by the laws of quantum physics. **qStream QRNG:** A Quantum Random Number Generator (QRNG) that produces 1 Gb/sec of true random numbers derived from a quantum source. NIST 800-90B certified as a true random entropy source. **qConnect Quantum Safe Key Distributor:** Distributes cryptographic keys protected by NIST-approved PQC algorithms and/or QKD platforms. Supports ETSI 014, Cisco SKIP, and NOKIA Key Output protocols. Available as a VM or network-attached appliance with QRNG. **qStream EaaS:** A cloud-hosted subscription service that distributes quantum entropy to devices and applications. **qRand Entropy Management Software:** Manages entropy from the qStream QRNG, eliminates entropy starvation in virtual environments, consolidates multiple entropy sources, and distributes entropy to multiple targets. **qClient SDK:** A vendor-neutral software development kit enabling developers to integrate key management and random number generation into applications, supporting KMIP and PKCS#11 APIs. **qProtect:** A data protection solution for sensitive and mission-critical data in uncontrolled or high-risk environments, supporting virtual zeroization and long-term post-quantum data protection.
