QuSecure, Inc. is an American cybersecurity company that builds software to help organizations protect against harvest-now-decrypt-later attacks and transition to quantum-resistant cryptography.
QuSecure was founded in 2019. In May 2022, the company announced its commercial launch and introduced its QuProtect platform along with its senior leadership team.[1] At the same year, QuSecure received a U.S. Small Business Innovation Research (SBIR) Phase III award related to post-quantum cryptography.[2]
On 27 March 2023, QuSecure and Accenture completed a live multi-orbit data communications test using post-quantum cryptography, demonstrating crypto-agility across satellite links.[3]
In May 2024, the company was named one of America’s Best Startup Employers by Forbes[4] and the 2024 Global Product Leader in the post-quantum cryptography industry by Frost & Sullivan.[5] At the same time, QuSecure announced that its QuProtect platform had achieved SOC 1 and SOC 2 Type II compliance.[6][7]
In June 2024, the company announced participation in industry initiatives, including NVIDIA’s cuPQC library and Accenture Project Spotlight.[8][9] Also, Frost & Sullivan named QuSecure Global Product Leader in Post-Quantum Cybersecurity.[10][11]
In February 2025, QuSecure announced the closing of an additional Series A funding round totaling $28 million, led by Two Bear Capital with participation from Accenture Ventures, and appointed Rebecca Krauthamer as chief executive officer.[12][13] In September, QuSecure launched QuProtect R3, a fully integrated, production-ready post-quantum cryptography (PQC) platform composed of Reconnaissance, Resilience and Reporting modules.[14]
QuSecure’s primary product is QuProtect, a cloud-native platform that provides post-quantum (quantum-resilient) cryptography and crypto-agility to protect data in transit and at rest.[15] Unlike traditional cryptographic upgrades that often require hardware overhauls, QuProtect utilizes a network-based model. This approach allows organizations to overlay quantum-resilient tunnels onto existing infrastructure without altering underlying application code.[16]
QuProtect was validated through independent audits (SOC 1 and SOC 2 Type II) and through ecosystem collaborations and tests — for example, a multi-orbit communications demonstration with Accenture and participation in NVIDIA’s cuPQC initiative.[17]
QuSecure is an early participant in the U.S. federal government’s transition to quantum-resilient standards.[18] The U.S. General Services Administration (GSA) has identified the company as a provider for PQC products within the federal ecosystem. The company’s technology has been utilized in pilot deployments and demonstrations, including a 2023 multi-orbit satellite communications link conducted in collaboration with Accenture, which tested PQC across low-Earth orbit (LEO) and geosynchronous orbit (GEO) satellites.[19]
