OPEN SOURCE • DEFENSIVE SECURITY

FALCO Guardian Open-Source Cyber Defense

A local-first defensive security platform for Linux infrastructure. FALCO Guardian collects security telemetry, detects suspicious activity and turns events into actionable incidents — without exposing the protected node directly to the public Internet.

The Pillars of FALCO

Built for defensive visibility, local control and practical incident detection on infrastructure you are authorized to protect.

Host & Network Visibility

Collect and correlate relevant host and network telemetry to provide continuous visibility into protected Linux assets.

eBPF Telemetry

Low-level Linux observability using eBPF components, designed to capture security-relevant events with minimal intrusion.

Detection Engine

Detection logic for SSH brute-force, port scanning, anomalous logins, suspicious activity and potential data exfiltration.

From telemetry to actionable incidents.

FALCO Guardian turns collected security events into structured detections and incidents. The dashboard provides a clear view of events, incidents, assets, severity and asset risk while keeping the protected node local-first.

  • Local-first monitoring of authorized Linux infrastructure
  • Event → detection → incident correlation pipeline
  • Optional outbound-only communication to a remote control plane

FALCO Guardian Architecture

A local-first defensive architecture that keeps protected Linux nodes private while turning security telemetry into actionable detections and incidents.

Telemetry Layer

Linux host and network telemetry is collected locally, including low-level eBPF security events.

Detection & Incidents

Events flow through defensive detection logic and are correlated into structured incidents for investigation and response.

Zero Public Inbound

The protected node does not require direct public inbound exposure. Optional remote communication is designed to be outbound-only.

Linux / eBPF→ Telemetry→ Detection→ Incident→ Dashboard / Response

Free & Open Source
