The short version

  • Only Cloud Native Buildpacks has a free tier, so it costs nothing to try first.
  • Each has a real cost: Cloud Native Buildpacks the operational cost is real: you own builder images, base image refresh cadence and migrations between specification versions, which currently sit at Buildpack API 0.10 and Platform API 0.12 with published migration guides, so breaking changes are a recurring chore.; Tenable pricing starts at $3500/year for Tenable One VM, expensive for small organizations
  • They diverge on capability: Cloud Native Buildpacks covers Detect and build lifecycle, Tenable covers Unified attack surface mapping.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Cloud Native Buildpacks

  • The operational cost is real: you own builder images, base image refresh cadence and migrations between specification versions, which currently sit at Buildpack API 0.10 and Platform API 0.12 with published migration guides, so breaking changes are a recurring chore.
  • A cold build with no warm cache is noticeably slower than a well layered Dockerfile, and because the cache lives in a cache image or volume, ephemeral continuous integration runners pay full price on every run unless you deliberately warm them.
  • Reproducibility depends on discipline rather than defaults, because buildpacks resolve runtime patch versions at build time unless you pin them and stability is only as good as the builder image tag you point at.
  • The specification is neutral but the buildpacks are not, and in practice you depend on Paketo, Heroku or Google, whose roadmaps, support levels and update cadences differ; CNCF also records contributing organisations down 12 per cent year on year.
  • Native dependencies, unusual monorepo layouts and non-standard project structures push you into writing custom buildpacks or extensions, which is a genuine engineering investment and not a configuration change.

Tenable

  • Pricing starts at $3500/year for Tenable One VM, expensive for small organizations
  • Many enterprise features require custom quote and sales engagement
  • Cloud Exposure, OT Exposure, and other modules have no published pricing
  • Multi-year contracts common, limiting flexibility
  • Setup and configuration complexity for enterprise deployments

Answered from the vendors’ own pages

Cloud Native Buildpacks: What does CNCF graduation actually change?

Nothing technically, but it signals audited governance, security review and multi-vendor maintenance, which is usually what a procurement or risk team needs before approving a build system.

Tenable: How is Tenable One pricing structured?

Tenable One Vulnerability Management costs $3500/year per 100 assets. Web App Scanning is $3578/year per 5 FQDNs. Multi-year discounts are available.

Source
Cloud Native Buildpacks: How is this different from writing a Dockerfile?

Container build knowledge lives with the platform team in a builder image rather than in every repository, and rebasing lets you patch the runtime base of many images without rebuilding them.

Tenable: What is the difference between Nessus Professional and Nessus Expert?

Nessus Professional costs $4790/year and provides core vulnerability scanning. Nessus Expert costs $6790/year and offers advanced scanning capabilities.

Source
Cloud Native Buildpacks: Does it cost anything?

No. The specification and tooling are Apache-2.0 and free. You pay only if you buy commercial support for a specific buildpack distribution from Broadcom, Heroku or Google.

Tenable: Are custom support and training available for Tenable?

Yes. Optional advanced support is available for $400/year. Training courses range from $275-$385/year.

Source
Cloud Native Buildpacks: Is it slower than a Dockerfile?

On a cold build with no cache, yes. Warm builds are competitive, but continuous integration runners that start empty every time will feel the difference.
