Secure-IC Enables World’s First PSA Level 4 Certification within Silicon Labs Series 3’s Secure Vault
Oct. 14, 2025 –
Secure-IC 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 Plaftorm, 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.”
