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.; One Identity the portfolio is assembled from separate acquisitions, so components are separately licensed, separately administered and do not present one console, which raises operational cost.
  • They diverge on capability: Falco covers eBPF kernel instrumentation, One Identity covers Identity Manager.
  • Prices and features above were last checked on 1 September 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 One Identity
  • A regulated business required to evidence host and container intrusion detection on Kubernetes nodes for an auditnot One Identity
  • A security team wanting a vendor-neutral detection layer whose rules they can read and modify rather than a black-box agentnot One Identity
  • A cluster where a compromised dependency might write to sensitive paths or open unexpected outbound connections, and only kernel-level visibility will catch itnot One Identity

One Identity

  • An organisation whose authoritative directory will remain on premises Active Directory and needs delegated administration with attribute-level controlnot Falco
  • A government or defence environment requiring privileged session management on a hardened physical appliance rather than a cloud servicenot Falco
  • A manufacturer with SAP and Active Directory needing provisioning governed under one certification processnot Falco
  • An enterprise consolidating Active Directory after an acquisition and needing automated account lifecycle across both forestsnot 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.

One Identity

  • The portfolio is assembled from separate acquisitions, so components are separately licensed, separately administered and do not present one console, which raises operational cost.
  • Identity Manager implementations are customisation-heavy and commonly run over a year, with the services spend exceeding the licence cost in the first year.
  • Quest has changed private equity ownership more than once since the Dell separation, and buyers should ask directly about product investment commitments before signing a multi-year deal.
  • Product documentation and support sit behind a customer portal, which makes independent evaluation before purchase harder than with vendors that publish openly.
  • The cloud-native and developer experience trails the pure-play identity vendors, so organisations moving decisively to SaaS applications find the on premises heritage becomes a constraint rather than an asset.

Questions people ask

Is Falco or One Identity better?
Neither clearly leads. Falco starts at Free and One Identity at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Falco or One Identity?
Falco has a free tier; the other does not. Paid plans start at Free for Falco and On request for One Identity.
Does Falco or One Identity run on more platforms?
Falco runs on Linux, Kubernetes, Self-hosted. One Identity runs on Web, Windows, Linux.
Can I use Falco for free?
Yes. Falco has a free tier, so you can try it without paying. One Identity 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 One Identity is typically brought in for.
What can Falco do that One Identity cannot?
Falco covers eBPF kernel instrumentation, System call rules engine, Container and Kubernetes context, Default rule set. One Identity covers Identity Manager, Safeguard, Active Roles, OneLogin.

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.

One Identity: Is One Identity the same company as Quest?

Yes. One Identity is Quest Software's identity and access management business unit, not a separate vendor.

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.

One Identity: Does it include privileged access?

Safeguard provides it, but it is licensed separately from Identity Manager. Neither includes the other.

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.

One Identity: Why choose this over SailPoint or Saviynt?

Almost always because of Active Directory depth via Active Roles or an appliance requirement for privileged sessions. For cloud-first estates the specialists are the stronger choice.

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.
