The short version

  • 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.; Osano the published visitor ceilings are low, with the paid self-serve tier stopping around 30,000 monthly visitors, so any consumer facing site with real traffic leaves published pricing immediately and negotiates a quote with no public anchor.
  • They diverge on capability: Falco covers eBPF kernel instrumentation, Osano covers Consent banner.
  • 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 Osano
  • A regulated business required to evidence host and container intrusion detection on Kubernetes nodes for an auditnot Osano
  • A security team wanting a vendor-neutral detection layer whose rules they can read and modify rather than a black-box agentnot Osano
  • A cluster where a compromised dependency might write to sensitive paths or open unexpected outbound connections, and only kernel-level visibility will catch itnot Osano

Osano

  • A mid market company selling into the EU and California that needs one banner honouring different consent rules by visitor regionnot Falco
  • A privacy counsel who wants a vendor that will contractually stand behind its consent product rather than disclaim all liabilitynot Falco
  • A marketing team that needs Google Consent Mode signals wired correctly so analytics and ads degrade rather than break when consent is refusednot Falco
  • A company with a handful of brand domains wanting one consent record and one scanning schedule across all of themnot 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.

Osano

  • The published visitor ceilings are low, with the paid self-serve tier stopping around 30,000 monthly visitors, so any consumer facing site with real traffic leaves published pricing immediately and negotiates a quote with no public anchor.
  • The no fines guarantee is bounded and conditional on configuring the product as instructed, so it is a marketing differentiator with an indemnity cap rather than the insurance policy the name suggests, and the limits should be read before it influences a decision.
  • Everything beyond consent, including subject rights automation, data mapping and vendor monitoring, is enterprise quoted, so the transparent pricing that attracts buyers covers only the cheapest part of the platform.
  • Tag blocking depends on tags being loaded through the mechanisms Osano can intercept, and marketing teams that inject scripts directly into templates or through server side tagging routinely leak trackers past the banner without anyone noticing.
  • It is a privacy platform rather than a security compliance one, so organisations that also need SOC 2 or ISO 27001 evidence collection run it alongside a separate tool and duplicate parts of the vendor and asset inventory.

Questions people ask

Is Falco or Osano better?
Neither clearly leads. Falco starts at Free and Osano at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Falco or Osano?
Falco starts at Free and Osano at Free.
Does Falco or Osano run on more platforms?
Falco runs on Linux, Kubernetes, Self-hosted. Osano runs on Web.
Can I use Falco for free?
Both have a free tier, so you can try either at no cost before committing.
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 Osano is typically brought in for.
What can Falco do that Osano cannot?
Falco covers eBPF kernel instrumentation, System call rules engine, Container and Kubernetes context, Default rule set. Osano covers Consent banner, Pre-consent tag blocking, Consent record, No fines guarantee.

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.

Osano: Does the free tier include the no fines guarantee?

No. The guarantee attaches to paid use of the consent product, and the free tier is capped at one domain and 5,000 monthly visitors.

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.

Osano: How is Osano priced?

By monthly website visitors, number of domains and tier. The self-serve path stops at a low visitor ceiling and everything above is quoted.

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.

Osano: Can it handle US state privacy laws as well as GDPR?

Yes, with region aware rule sets covering GDPR, ePrivacy and the US state regimes, so an EU visitor sees an opt-in banner and a US visitor sees the applicable opt-out.

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.

Osano: Does Osano do subject access requests?

Yes, but in the enterprise tier rather than the published plans, and it is quoted separately from consent.
