SEALSQ’s VaultIC 408 Meets FIPS 140-3 Requirements, Advancing NIST Certification and Strengthening Leadership in Secure IoT and Smart Grid Solutions
SealSQ’s VaultIC 408
SEALSQ Corp, a company that focuses on developing and selling Semiconductors, PKI and Post-Quantum technology hardware and software products, has announced a 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 Internet of Things (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 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). This step reinforces SEALSQ’s leadership in delivering high-security hardware for IoT ecosystems, Smart Grid infrastructure, and other critical applications.
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. Optimised 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, the 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, defence 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 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.
