Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Kustomize

  • No packaging or distribution story, which is exactly what Helm charts provide
  • Deeply nested overlays become hard to follow, and reasoning about the final output requires building it
  • No release lifecycle: nothing tracks what is installed or supports rollback the way Helm does
  • Patch syntax is fiddly for anything beyond simple field replacement

Orca Security

  • No public pricing; requires a demo and custom quote from sales.
  • Agentless-only scanning may miss some runtime telemetry that agent-based tools capture.
  • Full value depends on integrating many of the platform's modules across code, cloud, and AI.
  • Primarily targeted at mid-to-large organizations with multi-cloud environments.
