QuSecure Banks $28M Series A for Post-Quantum Cryptography Tech

QuSecure is pitching a software-based security architecture that overlays onto current networks to help businesses with PQC migration.

QuSecure, a Silicon Valley startup building technology to help organizations manage post-quantum cryptography (PQC) migration, has closed an additional round of Series A funding, bringing the total raised to $28 million. 

The round was led by Two Bear Capital with participation from Accenture Ventures, as the company looks to expand its quantum-resistant security technologies across government, financial, and critical infrastructure sectors.

QuSecure’s capital raise comes amidst urgency around quantum-safe encryption. The company and its investors are betting on an expanding market for solutions to help companies deal with the mandatory transition to quantum-resistant cryptographic standards.

As quantum computing advances, traditional encryption methods risk becoming obsolete, jeopardizing sensitive financial transactions, government communications, and corporate data. In response, the U.S. government has rolled out new mandates, including a January executive order that accelerates the shift to quantum-resistant cryptographic standards.

QuSecure’s flagship product, QuProtect, is designed to help organizations migrate to PQC without overhauling existing infrastructure. The company touts a software-based security architecture that overlays onto current networks, providing cryptographic agility and multi-layered protection. 

The company said it has found traction with a customer base that includes the US Army and Air Force, major telecommunications firms, financial institutions, and global cloud service providers.

Alongside the funding, QuSecure announced the appointment of co-founder Rebecca Krauthamer as Chief Executive Officer (CEO). Krauthamer previously served as VP of Engineering and Chief Product Officer and brings a background in artificial intelligence, having studied Symbolic Systems at Stanford.

“The quantum threat isn’t a distant possibility. It’s a reality that organizations need to address today,” Krauthamer said in a note announcing the new financing.

“It is critical that we evolve from encryption management that requires several years to upgrade algorithms to orchestrated crypto agility for the ability to push a button and upgrade an entire system at once,” Krauthamer said. “The ability to orchestrate cryptography at enterprise scale is critical to a robust cybersecurity strategy.”
