## What it is
Fibratus is a Windows security sensor that performs realtime threat detection by analyzing kernel and system telemetry (including ETW events) against a behavior-driven rule engine and YARA memory scanner. It supports routing events to output sinks, writing capture files for forensics, and extending functionality via Python-based filaments.

## Use cases
- detect malware and attacker tradecraft on windows endpoints in realtime
- monitor process, file, registry and network activity via etw telemetry
- write behavioral detection rules mapped to mitre attack techniques
- scan process memory with yara for malicious payloads
- capture system events for forensic analysis
- forward security events to a siem or output sinks
- extend detection tooling with python filaments

## When to choose
- you need an open-source edr-style sensor for windows hosts
- you want kernel-level telemetry with a flexible rule engine
- you need memory scanning and event capture for forensics on windows

## When to avoid
- you need threat detection on linux or macos
- you want a fully managed commercial edr with vendor support
- your focus is network-only intrusion detection rather than endpoint telemetry

## Facets
- artifact type: application
- maturity: active
- function: security, monitoring, alerting, logging
- domain: security, windows, developer-tools
- platform: windows
- tags: edr, threat-detection, etw, yara, mitre-attack, blueteam, forensics, kernel-telemetry
