The short version

  • Only Podman has a free tier, so it costs nothing to try first.
  • Each has a real cost: Podman native support is Linux-first; macOS and Windows run containers inside a managed virtual machine, which adds a layer Docker Desktop users may not expect; Tenable pricing starts at $3500/year for Tenable One VM, expensive for small organizations
  • They diverge on capability: Podman covers Daemonless architecture, Tenable covers Unified attack surface mapping.
  • Prices and features above were last checked on 29 August 2026.

Where each one falls short

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

Podman

  • Native support is Linux-first; macOS and Windows run containers inside a managed virtual machine, which adds a layer Docker Desktop users may not expect
  • Docker Compose support arrives through a compatibility layer rather than natively, and complex Compose files can hit gaps
  • Rootless mode has real constraints around privileged ports and some storage drivers
  • Smaller ecosystem of tutorials and third-party integrations than Docker, so unusual problems have fewer existing answers

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

Podman: Is Podman free?

Yes. Podman is open source with no licence fee, for personal or commercial use.

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
Podman: Can Podman replace Docker?

For most everyday use, yes. The CLI is deliberately Docker-compatible and many teams alias docker to podman. Gaps appear mainly around Docker Compose and Docker Desktop-specific features.

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
Podman: What does daemonless actually mean?

Docker runs a central background service as root that owns every container. Podman does not: each container is a child process of the user who ran it, so containers can run without root privileges at all.

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
Podman: Does Podman work on macOS?

Yes, but through a managed Linux virtual machine, because containers are a Linux kernel feature. That is the same approach Docker Desktop takes.
