SEALSQ Partners with Airmod to Embed a Quantum-Ready Middleware Platform Aiming at Cutting Secure IoT Development Time by Up to 50%

Geneva, Switzerland, Dec. 15, 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 product, and Airmod, a renowned French-based embedded software design house specializing in secure electronic systems for aerospace, drones, consumer electronics, and IoT applications, today unveiled a game-changing partnership: a production-ready, open-source-enabled middleware stack built directly on SEALSQ Secure DevKits, designed to fast-track the deployment of quantum-resistant devices. This collaboration aims to accelerate the creation of secure IoT applications, thus has the potential to reduce development time by up to 50%.

The partnership leverages SEALSQ's expertise in certified secure hardware, pioneering over 130 patents in post-quantum cryptography, with Airmod's 25+ years of software development experience in video processing, embedded cybersecurity, and high-speed communications. Together, the companies aim to deliver end-to-end solutions for industries that require unbreakable security, including aerospace, unmanned aerial vehicles (UAVs), and IoT applications where data integrity and low-latency transmission are critical.

The new Airmod Middleware for SEALSQ Secure Hardware turns months of complex cryptographic integration into days. OEMs, drone manufacturers, satellite operators, and industrial IoT innovators can now plug quantum-proof security into their products virtually out-of-the-box, with full secure boot, hardware-rooted trust, and post-quantum cryptography already pre-integrated and validated.

Accelerated Integration for Secure Device Deployment:

The developed middleware delivers a unified abstraction layer enabling seamless use of SEALSQ's secure hardware platforms within AIRMOD's middleware expertise.

Key features include:

• Optimized support for "Quantum Shield" QS7001 secure hardware platform, including secure boot, key storage, and hardware-rooted trust services.
• Pre-validated APIs for rapid application development.
• Streamlined onboarding workflows compatible with large-scale IoT deployments.
• Native support for post-quantum-ready architectures, aligning with emerging regulatory and industry requirements.

Expanded Partner Support Driven by AIRMOD Expertise

Through this collaboration, AIRMOD will provide comprehensive support to partners integrating SEALSQ chipsets, including:

• Developer Kits: Ready-to-use kits that accelerate prototyping and integration, enabling a faster time-to-market.
• Full Development Services: End-to-end software development for secure applications, from design to large-scale deployment.
• Global Reach: Worldwide service availability, ensuring consistent quality and compliance across regions.
  
  
  
  

AIRMOD brings extended security expertise in embedded electronics, making it uniquely qualified to deliver secure, reliable, and high-performance software for SEALSQ chipsets.
