Applies to

  • Consumer IoT devices such as cameras, hubs and sensors
  • Companion mobile apps and cloud services
  • Manufacturers designing a security baseline programme

What it does not cover

  • Industrial or medical device security requirements
  • Full ISO 27001 style management system certification
  • Legal data protection compliance

Verification checklist
