PSA Certified: Expert IoT Security Framework and Certification
Arm first introduced the concept of a IoT security framework in 2017 and is a co-founder of PSA Certified – a security framework and independent third-party evaluation scheme to help companies build-in the right level of device protection.
PSA Certified has scaled to become one of the fastest growing, most valued security ecosystems globally, and continues to break down the barriers to world-class security. Arm remains an active co-founder of PSA Certified and is heavily involved in providing architecture specifications and security resources.
PSA Certified 2024 Security Report: Scaling Security in the Age of AI
The industry is at a turning point in security. The PSA Certified 2024 Security Report revealed 80% of business leaders say that compliance with security regulations is a top priority in 2024. And as the rise of artificial intelligence (AI) increases the emphasis on security, the PSA Certified 2024 Security Report reveals the importance of security for AI, the opportunities for the ecosystem, and how to achieve security in the age of AI.
PSA Certified Benefits
Accelerates the development of secure systems using a trusted approach designed by experts.
Increase access to global markets, thanks to alignment to industry and government standards, plus emerging IoT legislation.
PSA Certified offers an industry-standard measurement on security implementation, checked by independent labs and third parties.
Four Steps To Ease Security Design
The PSA Certified framework was created to help ensure security is designed into a device from the ground up. The four PSA Certified stages guide security implementation for each specific use case:
- Analyze: the evaluation of assets and assessment of threats to define specific security requirements.
- Architect: the security design based on identified security requirements.
- Implement: the process of bringing together hardware and firmware using open source firmware implementations.
- Certify: assurance that products adhere to security requirements and the 10 security goals outlined by PSA Certified.
Check out this white paper for an in-depth explanation of PSA Certified and an overview of the four stages.
Growing Industry Momentum
Built on industry best practices, PSA Certified goes beyond outlining security rules and guidelines, providing practical implementation guides and tools.
Arm works closely with the other PSA Certified founders to simplify and accelerate the path to more secure systems, redefining security for connected devices. Many industry leaders have already pledged their support for PSA Certified with over 180 certifications to date.

The Arm Ecosystem: Security Made Simple
Arm puts security at the heart of every connected product. Originally spearheaded by Arm with support from CAICT, ProvenRun, Riscure, SGS Brightsight, TrustCB, and UL, PSA Certified provides a security-by-design scheme that starts with the root of trust and aligns to the cybersecurity requirements of USA, Europe, and China.
Arm is committed to making security easier to achieve using the Arm architecture. We continue to provide industry-leading security specifications and guides, paving the way for a more secure, connected world.
Specifications and Guides
Arm provides security architecture specifications and guides to help architects and engineers develop the necessary hardware and firmware to build a Root of Trust and meet PSA Certified requirements.
PSA Certified APIs
The PSA Certified APIs provide programming interfaces within the device to underlying security services implemented into the silicon root of trust. They ensure application developers can leverage trusted functions while reducing time-to-market and security efforts. The PSA Certified APIs have been available from Arm for many years, and have now been moved into an open public GitHub repository to enable collaboration.
Trusted Firmware
Trusted Firmware provides an open source reference implementation of the PSA Certified guidelines by complying to the platform security architecture specifications and providing reusable components to build in fundamental security functions for devices based on Cortex-M and Cortex-A. The software ensures easy porting to chips and platforms and creates a trusted environment. Delivered in a CMSIS pack, the stack can be easily configured and adapted to custom hardware in several IDEs, including Arm Keil MDK.
