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.; TunnelBear free plan's data cap is small compared to competitors offering more generous free allowances.
  • They diverge on capability: Falco covers eBPF kernel instrumentation, TunnelBear covers Encrypted VPN tunnel.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

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.

TunnelBear

  • Free plan's data cap is small compared to competitors offering more generous free allowances.
  • Lacks advanced features like dedicated IP addresses or split-tunneling controls found in some rival VPNs.
  • Server network is smaller than large competitors like NordVPN or ExpressVPN.
  • No standalone router-level app, limiting whole-network protection options.

Questions people ask

Is Falco or TunnelBear better?
Neither clearly leads. Falco starts at Free and TunnelBear at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Falco or TunnelBear?
Falco starts at Free and TunnelBear at Free.
Does Falco or TunnelBear run on more platforms?
Falco runs on Linux, Kubernetes, Self-hosted. TunnelBear runs on windows, mac, linux, ios, android.
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 TunnelBear is typically brought in for.
What can Falco do that TunnelBear cannot?
Falco covers eBPF kernel instrumentation, System call rules engine, Container and Kubernetes context, Default rule set. TunnelBear covers Encrypted VPN tunnel, Server location switching, GhostBear obfuscation, Browser extensions.

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.
