Robert: Maker (security, electronics, ham radio callsign: HF1T, software-defined radio). Founder and part of the @teonite team. I would like to introduce our open-source security platform defguard to a wider audience. Anyone interested in securing their environments, projects and organisations is a target audience. I would like to talk about secure environments, projects and organisations - why it is important and then what can defguard provide in that aspect.
