The short version

  • Each has a real cost: Crossplane requires Kubernetes expertise and infrastructure; Falco falco detects and alerts but does not block; stopping an attack requires wiring up Falco Talon or your own response tooling, so out of the box a confirmed detection still means a human intervening after the fact.
  • They diverge on capability: Crossplane covers Kubernetes extension, Falco covers eBPF kernel instrumentation.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Crossplane

  • Building platform-as-a-service offerings for internal teamsnot Falco
  • Creating unified control layers for multi-cloud infrastructurenot Falco
  • Designing declarative APIs for infrastructure provisioningnot Falco

Falco

  • A platform team that needs to know when a shell is opened inside a production container, which image scanning cannot detect because it happens at runtimenot Crossplane
  • A regulated business required to evidence host and container intrusion detection on Kubernetes nodes for an auditnot Crossplane
  • A security team wanting a vendor-neutral detection layer whose rules they can read and modify rather than a black-box agentnot Crossplane
  • A cluster where a compromised dependency might write to sensitive paths or open unexpected outbound connections, and only kernel-level visibility will catch itnot Crossplane

Where each one falls short

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

Crossplane

  • Requires Kubernetes expertise and infrastructure
  • Steep learning curve for teams new to Kubernetes patterns
  • Provider ecosystem smaller than Terraform

Falco

  • Falco detects and alerts but does not block; stopping an attack requires wiring up Falco Talon or your own response tooling, so out of the box a confirmed detection still means a human intervening after the fact.
  • The default rule set is noisy in real clusters and generates a large volume of benign matches from normal operational activity; without weeks of tuning, alert fatigue sets in and the team stops reading the feed, which is the usual failure mode.
  • There is no storage, console, search or case management in the project, so a working detection capability means also running Falcosidekick, an event store, a dashboard and alert routing, all of which you build, host and maintain.
  • The modern eBPF driver requires kernel 5.8 or later; older hosts fall back to the legacy probe or the kernel module, which brings driver-building against kernel headers and the operational fragility that comes with it on every kernel upgrade.
  • Per-node syscall instrumentation carries measurable CPU overhead on busy hosts, and the cost scales with syscall volume rather than with cluster size, so the noisiest and most performance-sensitive workloads are exactly the ones that feel it most.

Answered from the vendors’ own pages

Crossplane: Is Crossplane free?

Yes, Crossplane is open source and free to use. It requires a Kubernetes cluster but has no licensing costs.

Source
Falco: Does Falco block attacks?

No. It detects and emits events. Response requires Falco Talon or your own automation on top.

Crossplane: What is Crossplane used for?

Crossplane is used to build control planes and platforms for infrastructure management, enabling platform teams to expose safe APIs to other teams.

Source
Falco: Is Falco owned by Sysdig?

Sysdig created and open sourced it, but it graduated within the CNCF in February 2024, so governance sits with the foundation rather than the vendor.

Falco: What does it cost?

The project is Apache 2.0 with no licence fee. The cost is the storage, routing, tuning and staff time needed to make its output useful.

Falco: What kernel version do I need?

Kernel 5.8 or later for the default modern eBPF driver. Older hosts need the legacy eBPF probe or the kernel module.
