Varydn constructs minimal, hardened Docker images. Compliance is enforced at every build step. Images are signed, SBOMs are generated, and only verified images land in the secure registry.
Varydn analyzes your application's runtime requirements and selects the smallest viable base, distroless, scratch, or Alpine, stripping everything unnecessary.
Automated multi-stage Dockerfile construction separates build tooling from the runtime image, build secrets, compilers, and test dependencies never land in production.
All hardened images run as non-root unprivileged users. Read-only filesystems and dropped Linux capabilities are enforced by policy, not by convention.
Every image is cryptographically signed using Sigstore/cosign. Deployment pipelines can verify signatures before pulling and unsigned images are rejected automatically.
Software Bill of Materials (CycloneDX or SPDX) is generated and attached to every image. Know exactly what's in every container you run in production.
Build inputs are locked and pinned. The same commit always produces the same image that is verifiable, bit-for-bit, with a full provenance chain traceable to source.
Varydn's integrated container registry isn't a general-purpose image store. It's a policy-enforced, access-controlled repository that only accepts images that have passed the full Varydn hardening pipeline. Unverified images are rejected at push time.
Docker Hardening and the Secure Registry are available in the Varydn Platform and Enterprise tiers. Request a demo to see the full pipeline.
