PSA Certified is a globally adopted security certification scheme for IoT hardware, software, and devices, maintained by GlobalPlatform. Its standardized, tiered assurance model helps manufacturers demonstrate security best practices and resilience against realistic software and hardware attacks. As an accredited PSA Certified evaluation lab, Keysight supports you from readiness assessment and pre-certification testing through formal evaluation, delivering the Evaluation Technical Report (ETR) required for PSA Certified certification.

Discovery and Scoping
We begin with a joint workshop to understand your architecture and markets, select the right PSA Certified level, and define the Target of Evaluation (ToE) and scope.
Training and Alignment (Optional)
SESIP/PSA training and workshops align your engineering and security teams on PSA concepts, requirements, and how PSA relates to other schemes.
Security Documentation and Evidence
We help you prepare threat models, architecture descriptions, questionnaires, and Security Target–style documentation so your ToE matches PSA Certified expectations.
Pre-Certification Assessment
Our experts perform pre-certification testing and vulnerability assessments, including software and (where applicable) physical attack evaluations, to identify gaps before formal evaluation.
Formal PSA Certified Evaluation
As an accredited lab and founding member of the program, we execute the independent evaluation at our lab, perform the required testing, and deliver the Evaluation Technical Report (ETR) to the PSA Certified.
Post-Certification & Next Steps
We support you in communicating your certification and planning the roadmap for future products or higher PSA Certified levels as your threat model evolves.
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.
