PSA Certified™ Security Assessment
Build trust in the security of your IoT chips, software, and devices through Keysight’s accredited PSA Certified evaluation services.
Build confidence in next-generation IoT security
PSA Certified is an independent, globally adopted security certification scheme for IoT hardware, software, and devices. It is maintained by GlobalPlatform and was originally developed by Arm and a consortium of security labs, including Riscure, now part of Keysight. The scheme provides a standardized framework and tiered assurance model that help designers demonstrate security best practices and protection against realistic software and hardware attacks.
As a fully accredited PSA Certified evaluation lab, Keysight evaluates your product against PSA Certified requirements and guides you from preparation through successful certification. We help you prepare your product for PSA Certified with pre-certification evaluations and readiness assessments, perform the formal security evaluation at our accredited lab, and deliver the Evaluation Technical Report (ETR) used by the PSA Certified program to issue the certificate.
Why get PSA Certified with Keysight?
What is PSA Certified?
PSA Certified is a multi-level security framework created for the IoT sector. It standardizes how chips, software platforms, and devices demonstrate security, from threat analysis and architecture through to independent evaluation and certification.
Key characteristics:
- Tiered security assurance: multiple levels of certification with increasing depth of testing and robustness requirements.
- Focus on Root of Trust: starts from the chip’s Root of Trust (RoT) and extends to system software and device applications.
- Broad applicability: applies to chips, software, and devices. Level 1 covers all three scopes, while higher levels focus primarily on silicon and RoT components.
For many semiconductor vendors, PSA Certified has become a default certification path to benchmark the security of silicon products and demonstrate comparable assurance across different chips.
How we work with you on PSA Certified
Where PSA Certified applies
PSA Certified is used across a wide range of connected products, from silicon building blocks to end-user devices in critical industries. Designed for compositional use, it allows vendors to build on top of PSA Certified chips and platforms and then certify their final devices more efficiently.
PSA Certified levels and typical use cases
PSA Certified Level 2 builds on Level 1 with independent lab testing focused on resistance to scalable remote software attacks against the PSA Root of Trust. Typical products include wireless SoCs and secure microcontrollers for smart home and building automation, smart home hubs, routers and gateways, as well as connected appliances, lighting controllers, and HVAC equipment exposed to larger networks or the internet.
PSA Certified Level 3 extends Level 2 to cover robustness against physical attacks and more advanced logical attacks, including side-channel and fault injection techniques. Typical products include automotive ECUs, digital key systems and vehicle gateways, smart meters and grid devices deployed in the field, and smart locks, secure access control systems, and payment terminals used in high-value or regulated environments.
PSA Certified Level 4 delivers the highest level of assurance in the framework, targeting integrated secure enclaves or elements and Root of Trust components that must withstand sophisticated physical and software attacks while protecting high-value assets such as cryptographic keys. Typical products include advanced secure elements and secure enclaves in wireless SoCs, chips used in safety-critical industrial and automotive systems, and platforms that protect sensitive models, credentials, or data at the edge.
“This certification is a major milestone for Silicon Labs and a testament to the strength of our collaboration with Keysight. Achieving PSA Certified Level 4 required more than just technical readiness—it demanded a testing partner with deep expertise, flexible processes, and a shared commitment to security excellence. Keysight played a critical role not only in guiding us through the evaluation but in pushing the limits of what we could achieve. Their rigorous approach and hands-on support made it possible to reach this advanced level of assurance.”
