Radegast EDR
Detect threats. Respond fast. Trust your data.
Every line of code is public. Inspect it, fork it, contribute to it. No black boxes.
All your EDR telemetry is end-to-end encrypted. Your data is yours — always.
Radegast EDR is free. Cureated detections without an enterprise price tag.
Multi-layer endpoint detection
Radegast EDR combines three proven detection approaches on a single cross-platform agent.
Native Telemetry
ETW on Windows and eBPF on Linux — native kernel-level event streams for process, network, file, DNS, and registry activity.
Sigma Detection
Evaluate community Sigma rules for behavioral detections — PowerShell abuse, WMI execution, suspicious process chains, and more.
YARA Scanning
Scan executables at process creation and private memory regions for packed, obfuscated, or runtime-unpacked malware.
IOC Matching
Fast deterministic checks against file hashes, IP addresses, domains, and path regexes for threat intel and IR workflows.
SIEM-ready Output
Alerts are written as ECS 9.3.0 NDJSON — drop them straight into Elastic, Splunk, or any log pipeline without transformation.
Built in Rust
Memory-safe, zero garbage-collection pauses, minimal footprint. The agent stays out of your way while staying in the fight.
Up and running in four steps
Register at the Console
Create your free Radegast account at console.radegast.app. No credit card, no commitment.
Create a new device
Add a device from the Console dashboard. You'll get a unique agent configuration tied to that endpoint.
Select your detections
Choose which detection layers to enable — Sigma behavioral rules, YARA scanning, IOC matching, or all three.
Deploy the agent & watch telemetry roll in
Drop the agent binary on your device and start it. Alerts appear in the Console in real time, end-to-end encrypted.
