Every time you pull a container image, you’re trusting hundreds of packages you didn’t explicitly choose. The base image brings its OS packages, your dependencies bring their dependencies, and somewhere in that stack is the next CVE waiting to be discovered.
An SBOM (Software Bill of Materials) inventories everything inside a container. But a single snapshot only tells you what’s there now. The real value comes from comparing them: what changed? What got added? What got removed?
I went looking for a tool that could diff SBOMs, flag integrity drift, enforce policies, and slot into CI without friction. Found plenty of SBOM generators, but nothing that handled comparison the way I needed. So I built sbomlyze for myself. Turns out others had the same gap.
This post covers using sbomlyze to answer those questions,from basic diffs to drift detection, policy enforcement, and CI integration.
