The short version

  • Only Falco has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; TrustArc the software layer is generally shallower than OneTrust, particularly automated data discovery across large heterogeneous estates, so organisations with sprawling infrastructure often still need a separate discovery tool.
  • They diverge on capability: Falco covers eBPF kernel instrumentation, TrustArc covers Nymity Research.
  • 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.

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

TrustArc

  • A consumer brand that needs an independent privacy seal on its website because enterprise customers or app stores ask for third-party verificationnot Falco
  • A multinational privacy team that needs a maintained answer to what a given jurisdiction requires without retaining outside counsel for every questionnot Falco
  • An organisation running DPIAs at volume that wants templates tied to a maintained regulatory library rather than to a consultant word documentnot Falco
  • A privacy programme being audited that needs documented maturity benchmarking against a recognised framework of programme activitiesnot Falco

Where each one falls short

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

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.

TrustArc

  • The software layer is generally shallower than OneTrust, particularly automated data discovery across large heterogeneous estates, so organisations with sprawling infrastructure often still need a separate discovery tool.
  • The integration catalogue is smaller than the market leader, which means more of the data inventory is maintained by hand and drifts out of date between reviews.
  • Certification services are sold separately from the platform subscription, so the seal that is often the reason for choosing TrustArc is an extra line item and an extra annual renewal.
  • Reported contract values vary enormously by module mix and organisation size, and the absence of published pricing means smaller buyers have no anchor and routinely discover the entry price is higher than expected.
  • TrustArc stays inside privacy, so organisations that later want third-party risk, security compliance or ethics reporting on the same platform will be running a second vendor anyway.

Questions people ask

Is Falco or TrustArc better?
Neither clearly leads. Falco starts at Free and TrustArc at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Falco or TrustArc?
Falco has a free tier; the other does not. Paid plans start at Free for Falco and On request for TrustArc.
Does Falco or TrustArc run on more platforms?
Falco runs on Linux, Kubernetes, Self-hosted. TrustArc runs on Web.
Can I use Falco for free?
Yes. Falco has a free tier, so you can try it without paying. TrustArc starts at On request.
What is Falco best used for?
Falco is most often used for 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 runtime, a regulated business required to evidence host and container intrusion detection on kubernetes nodes for an audit, a security team wanting a vendor-neutral detection layer whose rules they can read and modify rather than a black-box agent, a cluster where a compromised dependency might write to sensitive paths or open unexpected outbound connections, and only kernel-level visibility will catch it. Of those, 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 runtime and a regulated business required to evidence host and container intrusion detection on kubernetes nodes for an audit are not what TrustArc is typically brought in for.
What can Falco do that TrustArc cannot?
Falco covers eBPF kernel instrumentation, System call rules engine, Container and Kubernetes context, Default rule set. TrustArc covers Nymity Research, TRUSTe certification, Consent and preference management, Privacy assessments.

Answered from the vendors’ own pages

Falco: Does Falco block attacks?

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

TrustArc: What does TrustArc have that OneTrust does not?

Nymity Research, a maintained regulatory intelligence library acquired in 2019, and the TRUSTe third-party certification and seal programme.

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.

TrustArc: How much does TrustArc cost?

Not published. Reported enterprise agreements range widely depending on modules and organisation size, and certification services are quoted on top of the platform subscription.

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.

TrustArc: Is TRUSTe the same company?

Yes. TrustArc is the renamed TRUSTe business and still operates the TRUSTe certification programme as a subsidiary.

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.

TrustArc: Does it handle cookie consent for Europe?

Yes, it includes a consent manager with scanning and banner delivery, though pure-play consent vendors are cheaper if that is all you need.
