Christian Johannsen

I'm a Staff Solutions Architect at Chainguard, where I help teams adopt secure software supply chains. My career spans from early '90s networking through modern DevSecOps, container security, and AI implementations. Break Glass Notes is where I write about the practical gaps I hit in the field — the questions dashboards can't answer, the feeds that don't exist, and the tooling I end up building to fill them. Expect posts on container images, SBOMs, FIPS compliance, CVE tooling, and the occasional deep dive into registry APIs.
