An design assessment provides insights into the security of a device using design documentation. An on-site visit may be required in order to digest the design documentation effectively. The output can be used to improve the security of a device even before it hits the field.


An implementation assessment provides insights into the security of a product using e.g. source code or the device itself. The output includes, among others, description of the approach taken, description of identified vulnerabilities and recommendations to improve the device.


A security workshop (on-site or online) provides a unique hands-on experience where the attendees get exposed to various topics important for hardening embedded devices. It is an effective approach for sharing the output from a design assessment or implementation assessment.
