Your CI\/CD pipeline is probably producing more data than you realize. A single build can leave container images, binaries, packages, logs, SBOMs, test reports and temporary files lying around. Add the copies made for pull requests and staging environments, plus everything from failed builds, and the pile grows quickly. <\/p>\n\n\n\n

The way most teams deal with it is to store everything and clean up later. Later never really happens. Storage costs keep creeping up, and old artifacts and test data slowly become security liabilities nobody is watching. It doesn\u2019t help that no one clearly owns the problem. Platform engineering runs the pipeline. Security owns the controls. Data teams own the databases. The stuff the pipeline keeps producing? Nobody\u2019s. That needs to change. <\/p>\n\n\n\n

Build artifacts are part of your software supply chain<\/strong> <\/h2>\n\n\n\n

An artifact isn\u2019t some temporary file on the way to production. It\u2019s what you actually deploy. 

Suppose someone can swap a trusted artifact for a malicious one after the build finishes. Everything you did earlier suddenly counts for much less. Your code review was clean, the SAST scan passed, the approvals were followed to the letter, and you still deployed the wrong binary. SolarWinds is a good reminder of why the supply chain deserves the same attention as production infrastructure. <\/p>\n\n\n\n

Provenance matters more than just protecting the repository<\/strong> <\/h2>\n\n\n\n

Plenty of organizations put their energy into access control around the artifact repository. Fair enough, you need it. But it\u2019s only half the picture, because there\u2019s a more basic question: where did this artifact come from? <\/p>\n\n\n\n

For a production binary or container image, that means knowing which commit produced it, which build system built it, which dependencies went in, and whether the build process itself can be trusted. Signing helps. Sigstore, for one, can show that an artifact came from the build process you expected. An SBOM gives you a view of the dependencies, and provenance data aligned with SLSA tells you more about how the artifact was made. <\/p>\n\n\n\n

Nobody is asking you to collect more security paperwork. What you want is for any production artifact to be explainable. And if nobody can explain where a binary came from, why would the deployment system trust it?

Retention is a security issue, not only a finance one<\/strong> <\/h2>\n\n\n\n

Here\u2019s a habit that\u2019s common in CI\/CD: build something, push it to the registry, forget about it. Do that hundreds of times a day for a few years and the registry gets expensive fast. <\/p>\n\n\n\n

Cost isn\u2019t the only worry, though. An old container image can still carry an old vulnerability.

A forgotten package might hold credentials or sensitive configuration that should never have been in it. A developer could even deploy an outdated image by accident, just because it\u2019s still there under a tag they recognize. Retention policies shrink that exposure. <\/p>\n\n\n\n

A production release may have to stay around for years. A pull-request build almost certainly doesn\u2019t. Giving them the same retention period just because they sit in one repository makes little sense. A simple policy might look like this:
