SEALSQ's Announces Its VaultIC 408 Meets FIPS 140-3 Requirements

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 announced a groundbreaking development in the field of network security. As per the UL Labs report, VaultIC 408 meets FIPS 140-3 requirements, advances NIST certification and strengthens SEALSQ's leadership in secure IoT and smart grid solutions.

SEALSQ's VaultIC 408 Secure Microcontroller (Module Name: VaultIC408 1.2.4, Hardware Version: AT90SO28RS rev A, Firmware Version: 1.2.4.1) has successfully passed NIST FIPS 140-3 testing at Security Level 3 (overall), as confirmed by a Validation Test Report submitted by UL Verification Services Inc. to the Cryptographic Module Validation Program (CMVP). The module's status is listed on the CMVP Modules In Process List at https://csrc.nist.gov/projects/cryptographic-module-validation-program/modules-in-process. This milestone reinforces SEALSQ's leadership in delivering high-security hardware for Internet of Things (IoT) ecosystems, Smart Grid infrastructure, and other critical applications.

Note: The Cryptographic Module Validation Program (CMVP) Modules In Process and Implementation Under Test (IUT) Lists are provided for information purposes only. Participation on the list is voluntary and is a joint decision by the vendor and Cryptographic Security and Testing (CST) laboratory. Modules are listed alphabetically by vendor name. Posting on the list does not imply guarantee of final validation.

The VaultIC 408 is a state-of-the-art secure microcontroller designed to safeguard connected devices against advanced cyber threats. It integrates hardware-based encryption, authentication, and key management within a tamper-resistant secure element, ensuring robust data integrity and device security. Optimized for IoT and Smart Grid applications, the VaultIC 408 supports low-power, compact designs for smart homes, industrial automation, healthcare, automotive, and digital identity solutions. It secures millions of smart grid hubs for renown device makers supplying for instance the UK's Smart Metering Implementation Programme (SMIP) and is also deployed in smart locks, drones, and satellite IoT platforms.

"UL Labs' report regarding VaultIC 408's FIPS 140-3 Level 3 compliance validates SEALSQ's commitment to delivering cutting-edge secure semiconductors," said Carlos Moreira, CEO of SEALSQ. "This achievement strengthens our ability to provide trusted solutions for global IoT and critical infrastructure markets."

The NIST FIPS 140-3 standard is the global benchmark for cryptographic module security, surpassing FIPS 140-2 with stricter requirements for algorithms, physical security, and operational resilience. It is mandated for U.S. federal agencies and widely adopted in energy, healthcare, defense, and financial sectors []. UL Labs, accredited by the National Voluntary Laboratory Accreditation Program (NVLAP) under Lab Code 100432-0, conducted rigorous testing to ensure compliance. The submitted Validation Test Report positions the VaultIC 408 for final NIST CMVP certification, expected in the coming months, enhancing its credibility for regulated markets.

This inclusion reinforces SEALSQ's position and strategic advancements in the IoT market projected to reach $1.1 trillion by 2030 and the Smart Grid market growing at a 20.8% CAGR through 2032. SEALSQ is poised to meet the rising demand for secure semiconductors.
