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.; Private Internet Access monthly plan is priced noticeably higher than the discounted multi-year commitments, penalizing short-term users.
  • They diverge on capability: Falco covers eBPF kernel instrumentation, Private Internet Access covers Split tunneling.
  • 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.

Private Internet Access

  • Monthly plan is priced noticeably higher than the discounted multi-year commitments, penalizing short-term users.
  • Dedicated IP and antivirus are paid add-ons rather than included features.
  • Headquartered in a jurisdiction whose privacy reputation some competitors market against, despite audited no-logs claims.
  • App interface is less streamlined than some higher-priced premium VPN competitors.

Questions people ask

Is Falco or Private Internet Access better?
Neither clearly leads. Falco starts at Free and Private Internet Access at $11.99/month, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Falco or Private Internet Access?
Falco has a free tier; the other does not. Paid plans start at Free for Falco and $11.99/month for Private Internet Access.
Does Falco or Private Internet Access run on more platforms?
Falco runs on Linux, Kubernetes, Self-hosted. Private Internet Access runs on windows, mac, linux, ios, android.
Can I use Falco for free?
Yes. Falco has a free tier, so you can try it without paying. Private Internet Access starts at $11.99/month.
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 Private Internet Access is typically brought in for.
What can Falco do that Private Internet Access cannot?
Falco covers eBPF kernel instrumentation, System call rules engine, Container and Kubernetes context, Default rule set. Private Internet Access covers Split tunneling, Kill switch, Ad and tracker blocking, Dedicated IP add-on.

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.

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.

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.

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.
