Guardener

The AI agent for frictionless trusted open source adoption

Guardener intelligently automates migration to Chainguard's hardened open source artifacts, so teams standardize faster, and developers never break stride.

From legacy components to secure-by-default Chainguard artifacts

Adopt zero-CVE images and hardened GitHub Actions on day one

Standardize across teams without slowing developers

Get full migration visibility for engineering and security stakeholders

Continuously adopt secure-by-default artifacts as your environment evolves

Contextual analysis, not blind translation

Guardener reads the full environmental context before acting to make intelligent mapping decisions, rebuilding containers layer-by-layer and migrating actions org-wide in a single PR.

Validated before it reaches production

Every migrated artifact maintains functional equivalence, verified by thorough testing, so engineers can ship with confidence, not crossed fingers.

Runs where your code lives

Deploy Guardener locally or via GitHub integration to unlock deeper context and telemetry, with support coming soon for language libraries, Agent Skills, and more.

Full visibility after every migration

Whether it's a container image or a GitHub Action, every migration surfaces a detailed before-and-after: what changed, and what vulnerabilities it mitigated. Engineers and security stakeholders get the evidence to validate adoption and the audit trail to prove it.
