IoT security advances with Silicon Labs claiming the title of first to achieve PSA Level 4 certification.
Silicon Labs, a leading provider of advanced edge connectivity solutions, has made a significant stride in IoT security with the world's first PSA Level 4 certification for its Series 3 Secure Vault security subsystem, found in the SiXG301 System-on-Chip (SoC). This certification signifies the highest level of IoT security standard available today, offering advanced protection against sophisticated physical attack methods.
Advanced Protection against Physical Attacks
The Series 3 Secure Vault is built on a leading-edge 22 nm process node, enhancing security and performance over previous generations. It is designed to protect devices for over a decade against both current and emerging threats, helping secure IoT devices well into the future. The subsystem supports over-the-air firmware and software updates combined with real-time monitoring, enabling security to be maintained as a lifecycle rather than a one-time event.
Global Regulatory Compliance
The Series 3 Secure Vault helps customers meet global regulatory requirements, including the EU Radio Equipment Directive (RED), US Cyber Trust Mark, Singapore’s Cybersecurity Labeling Scheme (CLS), and other new mandates. This simplifies compliance across markets and delivers industry-leading security capabilities, building on Silicon Labs’ award-winning Series 2 platform.
The First Device with PSA Level 4 Certification
The SiXG301 SoC, the first device featuring this Secure Vault subsystem, is expected to be commercially available in Q3 2025. It exemplifies this advanced security foundation, providing a robust, future-proof security architecture tailored for IoT devices facing advanced physical attacks while enabling global regulatory compliance and ongoing security management.
A Holistic Approach to Security
Silicon Labs provides a holistic approach to security and expert guidance, giving product teams a head start on regulatory readiness and consumer trust, backed by independent lab validation. The company is headquartered in Austin, Texas, and has operations in over 16 countries.
Building on a Legacy of Security Excellence
Silicon Labs' Series 3 platform is built on a 22 nm process node and is an industry leader in security, scaling the award-winning Series 2 security legacy with PSA Level 4 capabilities. The company collaborated with Keysight Technologies to validate Secure Vault on Series 3 for PSA Level 4, ensuring the highest level of security for its customers.
