QuSecure

QuSecure, Inc. is an American cybersecurity company that builds software to help organizations prepare for and resist attacks enabled by future quantum computers. Its products focus on post-quantum cryptography (PQC), cryptographic discovery and orchestration ("crypto-agility"), and compliance.

History

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. At the same year, QuSecure received a U.S. Small Business Innovation Research (SBIR) Phase III award related to post-quantum cryptography.

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. In May 2024, the company was named one of America’s Best Startup Employers by Forbes and the 2024 Global Product Leader in the post-quantum cryptography industry by Frost & Sullivan.

In June 2024, the company announced participation in industry initiatives, including NVIDIA’s cuPQC library and Accenture Project Spotlight. Also, Frost & Sullivan named QuSecure Global Product Leader in Post-Quantum Cybersecurity.

In September, the World Economic Forum’s Quantum Application Hub was launched as a platform to present real-world applications of quantum technologies and support knowledge sharing among policymakers, industry, and academia.

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.

In May, Forrester Research referenced QuSecure’s approach to orchestrated crypto-agility in its Architect’s Guide to Quantum Security as an example of recommended practice for post-quantum cryptography migration.

Product

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.  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.

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.

QuSecure is an early participant in the U.S. federal government’s transition to quantum-resilient standards. 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.

In the financial sector, QuSecure’s implementation at Banco Sabadell was cited in a case study within the U.S. Securities and Exchange Commission’s (SEC) Post-Quantum Financial Infrastructure Framework.
