The short version

  • Only Falco has a free tier, so it costs nothing to try first.
  • Each has a real cost: Darktrace no pricing information published on website; vendors must request pricing through demo request form or contact sales; 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: Darktrace covers Self-learning AI, Falco covers eBPF kernel instrumentation.
  • Prices and features above were last checked on 31 August 2026.

  • Incident Responsenot 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 Darktrace
  • A regulated business required to evidence host and container intrusion detection on Kubernetes nodes for an auditnot Darktrace
  • A security team wanting a vendor-neutral detection layer whose rules they can read and modify rather than a black-box agentnot Darktrace
  • A cluster where a compromised dependency might write to sensitive paths or open unexpected outbound connections, and only kernel-level visibility will catch itnot Darktrace

Where each one falls short

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

Darktrace

  • No pricing information published on website; vendors must request pricing through demo request form or contact sales
  • No tiered pricing structure available to compare editions or select appropriate plan level before contacting sales

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

Darktrace: How much does Darktrace cost?

Darktrace does not publish pricing information on its website. To obtain pricing details and learn about available packages, customers must contact Darktrace directly by requesting a demo or reaching out through the company's contact form.

Source
Falco: Does Falco block attacks?

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

Darktrace: Does Darktrace offer a free trial?

Darktrace mentions a free trial option, but specific trial length, features included, and how to access it are not published on the website. Users must contact the company directly to inquire about trial availability.

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.
