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.; Metasploit the free Framework edition is command line only; the web interface is Pro only
- They diverge on capability: Falco covers eBPF kernel instrumentation, Metasploit covers Exploit database.

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 Metasploit
- A regulated business required to evidence host and container intrusion detection on Kubernetes nodes for an auditnot Metasploit
- A security team wanting a vendor-neutral detection layer whose rules they can read and modify rather than a black-box agentnot Metasploit
- A cluster where a compromised dependency might write to sensitive paths or open unexpected outbound connections, and only kernel-level visibility will catch itnot Metasploit
Metasploit
- Penetration testing and exploit development against known vulnerabilitiesnot Falco
- Validating whether a reported vulnerability is actually exploitablenot Falco
- Running phishing and credential attack simulations on the Pro editionnot 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.
Metasploit
- The free Framework edition is command line only; the web interface is Pro only
- Automated exploitation, automated credential attacks and antivirus evading dynamic payloads are restricted to Metasploit Pro
- Reporting, audit wizards, task chains and closed loop vulnerability validation are Pro only
- Rapid7 publishes no price for Metasploit Pro and routes buyers to contact sales

Questions people ask
- Is Falco or Metasploit better?
- Neither clearly leads. Falco starts at Free and Metasploit at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Falco or Metasploit?
- Falco starts at Free and Metasploit at Free.
- Does Falco or Metasploit run on more platforms?
- Falco runs on Linux, Kubernetes, Self-hosted. Metasploit runs on Desktop, Cli.
- 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 Metasploit is typically brought in for.
- What can Falco do that Metasploit cannot?
- Falco covers eBPF kernel instrumentation, System call rules engine, Container and Kubernetes context, Default rule set. Metasploit covers Exploit database, Payload generation, Post-exploitation, Evasion modules.
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.
Metasploit: Is Metasploit Framework free to use?
Yes, Metasploit Framework is available as free open-source software with source code accessible via GitHub. Community support is provided through Slack, GitHub, Twitter, and email.
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.
Metasploit: What is the difference between Metasploit Framework and Metasploit Pro?
Metasploit Framework is the free open-source version. Metasploit Pro is a commercial offering with customer support from Rapid7, though specific pricing and features are not detailed on the download page.
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.
Metasploit: What support is available for the free Framework version?
Community-based support for Metasploit Framework is available through Slack, GitHub, Twitter, and email ([email protected]). Commercial customers using Metasploit Pro receive customer support from Rapid7.
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.
