SEALSQ Expands Post-Quantum Leadership with Strategic Financial-Sector Investments and the Rollout of its Global PQC Deployment Strategy

Geneva, Switzerland, Oct. 28, 2025 (GLOBE NEWSWIRE) --

SEALSQ Corp (NASDAQ: LAES) ("SEALSQ" or "Company"), a company that focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products, today announces a major expansion of its post-quantum cybersecurity leadership through strategic initiatives designed to accelerate quantum-readiness across the global financial services industry.

While large-scale quantum computers capable of breaking today’s encryption may still be years away, the threat to sensitive financial information is immediate and active. Cyber-criminals and state-sponsored actors are already conducting “harvest-now, decrypt-later” attacks, capturing encrypted banking data today with the intent to decrypt it once quantum capabilities mature. This places historical and future records at risk, including client portfolios, cross-border payment data, SWIFT instructions, wealth-management records, contractual agreements, confidential supervisory filings, regulatory communications, and personal financial information.

Despite managing some of the world’s most sensitive data, financial institutions continue to lag behind other industries in adopting post-quantum technologies. This gap in a highly regulated and security-critical ecosystem represents a genuine systemic vulnerability. Digital finance, global trade, regulatory compliance, and consumer trust all depend on cryptographic security, and legacy cryptography will not withstand the next era of computing. Delaying preparation risks regulatory exposure, operational disruption, financial loss, and reputational damage.

SEALSQ has already begun executing its quantum transition strategy in the financial sector.

In Switzerland, the Company has launched its post-quantum readiness service supported by a strategic investment in Wecan, a provider of secure compliance and data-sharing infrastructure for regulated financial institutions. Together, SEALSQ and Wecan are developing a Post-Quantum KYC (Know Your Customer) solution designed to protect sensitive client information from collection to processing, securing it against future decryption attempts as quantum capabilities evolve. By combining SEALSQ’s expertise in post-quantum technologies with Wecan’s leading compliance backbone, the partnership is setting a new benchmark for privacy and resilience in financial data protection.
