Secure-IC Enables World’s First PSA Level 4 Certification within Silicon Labs Series 3 ’s Secure Vault

Cesson -Sévigné (France) - October 14, 2025 – Secure-IC, the rising leader and global provider of end-to-end cybersecurity solutions for embedded systems and connected objects, proudly announces its key role in enabling Silicon Labs' Series 3, within its Secure Vault security subsystem, to achieve the world's first PSA Level 4 certification, the highest level of protection recognized by PSA Certified. This historic milestone validates Secure-IC's cutting-edge technology, namely Securyzr™ S100 series derived from Securyzr™ neo Core Platform, serving as the advanced Root of Trust at the core of the Series 3's Secure Vault. It also demonstrates Silicon Labs' security leadership and stands as a testament to the longstanding partnership between the two companies, where semiconductor innovation meets world -class embedded cybersecurity expertise.

PSA Level 4 certification addresses resilience against the most advanced physical threats ,validating resilience against sophisticated physical attacks such as laser fault injection, side-channel analysis, microprobing, and voltage manipulation. Secure-IC's Securyzr™ neo Core Platform served as the Root of Trust (RoT) at the heart of the Series 3 Secure Vault subsystem, enabling Silicon Labs' SiXG301 SoC to withstand these advanced threats.

“Our collaboration with Secure-IC has been essential to pushing the boundaries of security in connected devices,”said Daniel Cooley, CTO and SVP, Silicon Labs. “ By integrating Secure-IC's Securyzr™ neo Core Platform as the Root of Trust in our Series 3 architecture, we achieved the world's first PSA Level 4 certification, delivering unparalleled protection today while building the foundation to keep our customers secure against tomorrow's evolving threats.”

A Partnership Built on Innovation and Trust

Secure-IC has been a trusted technology partner to Silicon Labs through successive security milestones, from PSA Level 3 achievements to today's breakthrough at Level 4. Together, the companies are enabling device makers to align with emerging global regulations, including the EU's Cyber Resilience Act (CRA) and the US Cyber Trust Mark, while also anticipating future security challenges.

“This certification underscores the maturity of our Securyzr™ neo Core Platform and the strength of our long-standing partnership with Silicon Labs,” said Hassan Triqui, CEO and Co-Founder of Secure-IC. “By uniting world-class embedded cybersecurity with Silicon Labs' leadership in secure and energy-efficient IoT solutions, we are shaping the future of trusted connected devices and reinforcing our shared commitment to raising the bar for the entire industry.”

Future-Proofing IoT Security

Secure-IC's Securyzr™ neo Core Platform combines versatility, performance, and robust security in a single, configurable Root of Trust. With advanced anti -tamper protection, secure lifecycle management, and certification -readiness for standards including FIPS 140 -3, Common Criteria and ISO 26262, it enables device makers to deploy tailored security solutions across diverse applications. By delivering both immediate protection and long-term resilience, Securyzr™ neo ensures that connected devices remain secure today and prepared for the challenges of tomorrow , such as the adoption of Post-Quantum Cryptography (PQC).

With billions of connected devices expected to enter the market in the coming years, PSA Level 4 certification provides assurance that Silicon Labs' and Secure-IC's solutions will remain resilient against evolving cyber and physical threats. Built on a 22nm process node, Silicon Labs' Series 3 devices with Secure Vault – powered by Securyzr™ neo – are engineered to provide protection over a decade in the field, giving customers long -term confidence, reducing security risks, and simplifying compliance with evolving standards.
