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.; Passbolt pro Edition requires a minimum of 10 users, making it costlier for very small teams.
- They diverge on capability: Falco covers eBPF kernel instrumentation, Passbolt covers Password sharing and folders.
- Prices and features above were last checked on 31 August 2026.
Where they differ
Only the attributes on which Falco and Passbolt actually diverge.
Identical on both: starting price (Free), free tier (Yes), user rating (Not yet rated), category (Cybersecurity).

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 Passbolt
- A regulated business required to evidence host and container intrusion detection on Kubernetes nodes for an auditnot Passbolt
- A security team wanting a vendor-neutral detection layer whose rules they can read and modify rather than a black-box agentnot Passbolt

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.
Passbolt
- Pro Edition requires a minimum of 10 users, making it costlier for very small teams.
- Community Edition lacks SSO and LDAP provisioning, which many organizations need for onboarding at scale.
- Self-hosting the Community Edition requires infrastructure and maintenance effort compared to fully managed competitors.
- Enterprise-tier support and HA consulting require custom, quote-based pricing rather than transparent rates.

Questions people ask
- Is Falco or Passbolt better?
- Neither clearly leads. Falco starts at Free and Passbolt at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Falco or Passbolt?
- Falco starts at Free and Passbolt at Free.
- Does Falco or Passbolt run on more platforms?
- Falco runs on Linux, Kubernetes, Self-hosted. Passbolt runs on web, windows, mac, linux, api.
- 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 Passbolt is typically brought in for.
- What can Falco do that Passbolt cannot?
- Falco covers eBPF kernel instrumentation, System call rules engine, Container and Kubernetes context, Default rule set. Passbolt covers Password sharing and folders, Groups and role-based access, Browser extensions and CLI, Open API.
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.
Passbolt: Is Passbolt free to use?
Yes. The Community Edition is free forever with unlimited users, including password sharing, folders, groups, role-based access, browser extensions, a CLI, and an open API.
SourceFalco: 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.
Passbolt: What does the Pro Edition cost and add?
Pro Edition costs $4.90 per user per month billed annually, with a 10-user minimum, and adds LDAP/AD provisioning, single sign-on, account recovery escrow, activity audit logs, and next-business-day support.
SourceFalco: 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.
Passbolt: What license is Passbolt distributed under?
All Passbolt editions, including Pro and Enterprise, are distributed under the AGPL v3 open-source license.
SourceFalco: 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.
