The Evolution of PSA Certified

PSA Certified at a Glance

PSA Certified is a security framework for the IoT sector. Initially introduced by Arm in 2017 as the Platform Security Architecture or PSA, it was designed to help developers build-in the right levels of security to connected IoT devices.

It has since evolved into a four-step process and, in 2019, six industry leaders joined Arm in founding PSA Certified. PSA Certified is a security framework certification program that demonstrates a commitment to security and alignment to worldwide requirements.

Since then, PSA Certified has seen global adoption and has defragmented security on a common Root of Trust, ensuring companies have the confidence to create innovative solutions without viewing security as an optional extra.
