QuSecure Banking Deployment Spotlighted in Proposed SEC Post-Quantum Financial Infrastructure Framework as Real-World Proof for Post-Quantum Migration

QuSecure’s Commercial Banking PQC Implementation with Banco Sabadell and Accenture Cited as Sole ‘Benchmark for Industry-wide Adoption Strategies’ by SEC

SAN MATEO, Calif. — March 19, 2026 — QuSecure™, Inc., the market leader in post-quantum cybersecurity and cryptographic agility, today announced that the Post-Quantum Financial Infrastructure Framework (PQFIF) submitted to the U.S. Securities and Exchange Commission’s Crypto Assets Task Force specifically cites QuSecure’s, Banco Sabadell’s, and Accenture’s four-month banking deployment as a real-world precedent for successful crypto-agile post-quantum cryptography (PQC) migration and quantum-safe cryptography. The PQFIF states the implementation demonstrates that “migration to post-quantum cryptography is both technically feasible and operationally practical for major financial institutions, providing a benchmark for industry-wide adoption strategies.”

Detailed in Sections Two and Seven of the proposed Post-Quantum Financial Infrastructure Framework, the QuSecure, Banco Sabadell, and Accenture deployment was chosen as the sole “Real-World Implementation Precedent”. The case study highlighted the realized benefits of the QuSecure QuProtect deployment, including that QuProtect’s “PQC implementation proved feasible within existing infrastructure frameworks, [its] network-layer encryption solutions enabled quantum-safe standards without complete system overhaul, [and its] crypto-agility approaches demonstrated practical viability for complex banking environments.”

Implemented in a live banking environment, the Banco Sabadell engagement demonstrates that quantum-safe migration can begin today without disruptive infrastructure replacement or multi-year system overhauls. The deployment shifts the industry conversation from long-term planning to immediate execution.

“The SEC framework goes beyond theory to real-world execution,” said Rebecca Krauthamer, Co-founder and CEO of QuSecure. “The PQFIF represents groundbreaking guidance that both recognizes the immediacy of the threat and gives financial sector practitioners a clear set of actions to take to move beyond strategy and crypto inventory before the clock runs out. I expect other highly regulated sectors - pharma, healthcare, and energy - to adopt the path laid out in the PQFIF as they formalize their own migration guidance. QuSecure is proud to continue our pioneering legacy, giving security leaders peer precedent and board-ready examples that quantum-safe progress can start now, pragmatically, in phases, and without operational disruption, alongside innovative and security-first organizations like Banco Sabadell and Accenture.”

The submitted Framework emphasizes the urgency of migration for the financial sector, highlighting the compression of timelines, and pointing to a Europol report that suggests the quantum threat could be realized as early as 2028.

According to the PQFIF, “The U.S. digital asset ecosystem, built upon current cryptographic standards, faces an existential threat from the rapid advancement of quantum computing. A cryptographically relevant quantum computer (CRQC) could break the fundamental security that protects trillions of dollars in assets leading to systemic risk, catastrophic investor losses, and a complete erosion of market confidence. The framework provides a structured methodology for assessing vulnerabilities, planning a risk-based migration, and implementing NIST-standardized cryptographic solutions without disrupting market operations. Action today is needed to secure investor assets and ensure the long-term integrity of U.S. capital markets in the quantum era.”

QuProtect’s production-ready remediation capabilities allow institutions to inventory, prioritize, and mitigate quantum risk while maintaining operational continuity. The engagement further underscores Accenture’s ability to guide complex, regulated institutions from post-quantum strategy to executed deployment, moving beyond advisory frameworks into executed deployment.
