Silicon-First Security with PSA Certified: Building Trust in Connected and Non-Connected Digital Devices from the Chip Up

Cybersecurity is no longer just a concern for connected devices; it’s essential for all digital products, including those that never connect to a network. From vehicles and medical equipment to smart infrastructure, any device that processes data is vulnerable to attack. As global regulations tighten, system designers and chip architects are under growing pressure to demonstrate robust, certifiable security built into their products from the ground up.

That’s where PSA Certified comes in.

Originally developed by Arm and security industry leaders, PSA Certified is a comprehensive framework and certification programme that helps manufacturers implement and validate silicon-level security. By establishing a hardware-based Root of Trust, PSA Certified ensures that security is not just layered on, but anchored in the chip itself – providing stronger resistance to both software and physical threats, and simplifying compliance with global standards such as the EU’s Cyber Resilience Act, UK PSTI, and US Cyber Trust Mark.

EnSilica’s latest white paper, Silicon-First Security with PSA Certified: Building Trust in Connected and Non-Connected Digital Devices from the Chip Up, outlines why this approach is critical for modern product design. It explores real-world attack scenarios, explains the four levels of PSA certification, and highlights how EnSilica supports customers throughout the security lifecycle with in-house cryptographic accelerators and PSA-aligned SoC design.

Whether you’re developing safety-critical automotive ECUs or industrial control systems, the message is clear: trust starts in hardware
