SEALSQ Corp (NASDAQ: LAES) announced its development of semiconductor solutions that embed Post-Quantum Cryptography directly into hardware to address cybersecurity threats from artificial intelligence systems.

The Geneva-based semiconductor company cited recent developments in AI capabilities, specifically referencing Anthropic's Claude Mythos Preview model released April 7, 2026. According to SEALSQ, this AI model demonstrates advanced capabilities in vulnerability discovery and has prompted Anthropic to restrict access and launch "Project Glasswing," a cross-industry security initiative.

SEALSQ stated that AI agents are becoming autonomous cybersecurity actors that can systematically explore attack paths and use sophisticated evasion techniques. The company argued this development amplifies quantum computing threats by enabling faster identification of cryptographic weaknesses.

The company emphasized that software-based security measures are insufficient against these emerging threats. SEALSQ's approach involves integrating Post-Quantum Cryptography algorithms directly into secure microcontrollers and semiconductor components.

"By embedding PQC into secure microcontrollers and semiconductor components, cryptographic operations are executed within tamper-resistant hardware environments, creating an immutable root of trust that cannot be altered, bypassed, or extracted—even by AI-driven attacks," the company stated.

SEALSQ develops hardware and software products focused on semiconductors, Public Key Infrastructure, and Post-Quantum technology. The company targets applications including multi-factor authentication tokens, smart energy systems, medical devices, defense systems, IT network infrastructure, automotive, and industrial automation.

The company's semiconductors are designed to protect against quantum computing threats to traditional cryptographic methods like RSA and Elliptic Curve Cryptography. SEALSQ stated its hardware-based approach reduces attack surfaces by operating entirely within secure environments.
