From legacy distros to production-ready Chainguard images

Give your developers confidence that your CI/CD pipeline doesn't become a pathway for bad actors to gain access to the keys to your kingdom.

01

Eliminate attacks against your most privileged OSS layer

02

Remove the guesswork from package mapping

03

Standardize across teams without slowing developers

04

Validate every layer before it reaches production

05

Report post-migration insights on vuln, size comparisons

Understand what's in use

See the container images and Actions your team is using across your repos.

Scale migration, fast

Guardener rebuilds and tests containers layer-by-layer, and opens a migration pull request for all actions with a drop-in Chainguard equivalent to ensure no breaking changes.

Full visibility after every migration

Every rebuild surfaces a detailed comparison of image size, vulnerability posture, and filesystem changes — giving engineers and security stakeholders the evidence to validate adoption and the audit trail to prove it.

Frequently Asked Questions

Will this interfere with our existing scanners / platform security?

No. There's no runtime agent or sidecar involved. The Guardener just produces a standard Dockerfile and image that you build locally with Docker, so it fits into your existing workflow.

What control do I maintain over the migrations?

You review the generated Dockerfile, and suggested Actions and app images and decide whether to accept them, just like any other code change.

What are your policies for data handling?
