Open Source

Radegast EDR is built on open-source foundations. Inspect the code, contribute, and own your security stack.

// open source

Radegast EDR is free, open-source, and licensed under the Apache 2.0 License. Every component is inspectable, forkable, and community-improvable.

We believe security software should be transparent by design. You should be able to verify exactly what telemetry is collected, how detections work, and what the agent can and cannot do on your systems.

The Detection Engine: Rustinel

Open-source endpoint detection engine

The core agent powering Radegast EDR is Rustinel — an independent open-source project by @Karib0u. It combines ETW, eBPF, Sigma, YARA, IOC matching, and ECS NDJSON alert output in a single Rust binary for Windows and Linux.

License

Radegast EDR and Rustinel are both released under the Apache License 2.0 — a permissive open-source license that lets you use, modify, and distribute the software freely, even in commercial contexts, with attribution.
