Falco vs OpenEBS
Falco
Cybersecurity
CNCF-graduated runtime threat detection for Linux and Kubernetes using eBPF
- From
- Free
- Rated
- -
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.; OpenEBS there is no vendor on the other end of an incident unless you separately contract DataCore, so an outage at three in the morning is resolved by your own team and a public Slack channel.
- They diverge on capability: Falco covers eBPF kernel instrumentation, OpenEBS covers Replicated engine.
- Prices and features above were last checked on 1 September 2026.
Where they differ
Only the attributes on which Falco and OpenEBS actually diverge.
Identical on both: starting price (Free), pricing model (Open source, no licence fee), free tier (Yes), user rating (Not yet rated).

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 OpenEBS
- A regulated business required to evidence host and container intrusion detection on Kubernetes nodes for an auditnot OpenEBS
- A security team wanting a vendor-neutral detection layer whose rules they can read and modify rather than a black-box agentnot OpenEBS
- A cluster where a compromised dependency might write to sensitive paths or open unexpected outbound connections, and only kernel-level visibility will catch itnot OpenEBS
OpenEBS
- Running Cassandra or Kafka on Kubernetes where the application already replicates and node-local volumes are sufficientnot Falco
- A platform team that needs persistent volumes on bare metal Kubernetes without a per node subscriptionnot Falco
- An edge or lab deployment where a commercial storage licence cannot be justifiednot Falco
- Replacing hostpath volumes with something that has snapshots and a Container Storage Interface drivernot 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.
OpenEBS
- There is no vendor on the other end of an incident unless you separately contract DataCore, so an outage at three in the morning is resolved by your own team and a public Slack channel.
- The project has several storage engines with different maturity and different operational characteristics, and choosing the wrong one for your workload produces poor results that look like a product failure.
- Documentation and upgrade guidance assume real Kubernetes storage knowledge, so teams without that expertise underestimate the operational load they are taking on.
- Project governance shifted after DataCore acquired MayaData in 2021, which means the direction of a supposedly neutral project is influenced by one commercial sponsor.
- Disaster recovery, cross-cluster replication and policy-driven data services are thinner than in the commercial alternatives, so organisations with those requirements end up building them or buying a product anyway.

Questions people ask
- Is Falco or OpenEBS better?
- Neither clearly leads. Falco starts at Free and OpenEBS at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Falco or OpenEBS?
- Falco starts at Free and OpenEBS at Free.
- Does Falco or OpenEBS run on more platforms?
- Falco runs on Linux, Kubernetes, Self-hosted. OpenEBS runs on Linux.
- 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 OpenEBS is typically brought in for.
- What can Falco do that OpenEBS cannot?
- Falco covers eBPF kernel instrumentation, System call rules engine, Container and Kubernetes context, Default rule set. OpenEBS covers Replicated engine, Local PV engines, Kubernetes-native management, Snapshots and clones.
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.
OpenEBS: Who supports it in production?
The project is community supported. Commercial support is available from DataCore, which acquired the original sponsor MayaData in 2021. Establish that relationship before production, not during an incident.
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.
OpenEBS: Which engine should we use?
If your application replicates its own data, use a Local engine and avoid replicating twice. If it does not, such as with PostgreSQL, use the Replicated engine.
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.
OpenEBS: Does it cost anything?
No licence fee. The cost is operational, and a support contract if you want someone accountable.
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.
