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.; SentinelOne enterprise pricing requires contacting sales
  • They diverge on capability: Falco covers eBPF kernel instrumentation, SentinelOne covers AI-powered detection.
  • 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.

SentinelOne

  • Enterprise pricing requires contacting sales
  • Prices shown for 5-100 workstations may differ for larger deployments
  • Purchases must be made through authorized third-party partners

Questions people ask

Is Falco or SentinelOne better?
Neither clearly leads. Falco starts at Free and SentinelOne at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Falco or SentinelOne?
Falco has a free tier; the other does not. Paid plans start at Free for Falco and On request for SentinelOne.
Does Falco or SentinelOne run on more platforms?
Falco runs on Linux, Kubernetes, Self-hosted. SentinelOne runs on Windows, Macos, Linux, Ios, Android.
Can I use Falco for free?
Yes. Falco has a free tier, so you can try it without paying. SentinelOne starts at On request.
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 SentinelOne is typically brought in for.
What can Falco do that SentinelOne cannot?
Falco covers eBPF kernel instrumentation, System call rules engine, Container and Kubernetes context, Default rule set. SentinelOne covers AI-powered detection, Autonomous response, Behavioral threat intelligence, Root cause analysis.

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.

SentinelOne: What is SentinelOne Singularity Complete pricing?

Singularity Complete costs $179.99 per endpoint per year and includes AI-driven endpoint and cloud workload protection, real-time threat detection and response, 14-day data retention, and AI Security Assistant. Pricing shown for 5-100 workstations.

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.

SentinelOne: What features distinguish SentinelOne Commercial from Complete?

Singularity Commercial costs $229.99 per endpoint per year (versus $179.99 for Complete) and adds Identity Detection and Response, 90-day data retention (compared to 14-day), and Managed Threat Hunting services.

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.

SentinelOne: How does partner pricing affect SentinelOne costs?

All SentinelOne purchases are made through authorized third-party partners, and partner pricing may differ from published rates. Customers should verify pricing with their authorized reseller.

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.

SentinelOne: What does SentinelOne Enterprise include?

Singularity Enterprise (custom pricing, contact sales) adds Agentic AI SOC Analyst and Full Visibility and Forensics capabilities to all Commercial features, plus expert-led onboarding and training.
