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.; Keeper Password Manager free tier limited to 10 passwords on one device only
  • They diverge on capability: Falco covers eBPF kernel instrumentation, Keeper Password Manager covers Zero-knowledge security.
  • Prices and features above were last checked on 31 August 2026.

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.

Keeper Password Manager

  • Free tier limited to 10 passwords on one device only
  • Personal and Family plans lack team collaboration features
  • Higher per-user cost for small teams compared to some competitors

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 Keeper Password Manager is typically brought in for.
What can Falco do that Keeper Password Manager cannot?
Falco covers eBPF kernel instrumentation, System call rules engine, Container and Kubernetes context, Default rule set. Keeper Password Manager covers Zero-knowledge security, Password vault, BreachWatch dark web monitoring, Secure file storage.

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.

Keeper Password Manager: Does Keeper offer a free tier?

Keeper's free version stores only 10 passwords on a single mobile device with no cross-device sync and is effectively a trial.

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.

Keeper Password Manager: What does Keeper Business cost?

Keeper Business Starter costs $2 per user per month for 5-10 users. Keeper Business costs $3.75 per user per month for unlimited users.

Source
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.

Keeper Password Manager: Does Keeper Enterprise include SSO?

Yes. Keeper Enterprise includes single sign-on capabilities along with compliance and reporting features at $6 per user per month.

Source
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.

Keeper Password Manager: What security features does Keeper include?

Keeper uses zero-knowledge encryption where the company cannot access passwords, plus advanced features like privileged access management and session recording on Enterprise Plus.
