# Customize Detections

You can expand the detection capabilities of Vigil in three ways:

* [Add custom YARA rules](/overview/customize-detections/add-custom-yara-signatures.md)
* [Add embeddings to ChromaDB](/overview/customize-detections/add-embeddings.md)
* [Create and implement custom scanner](/overview/customize-detections/custom-scanners.md)

If you have new prompt injection techniques you'd like to detect, adding embeddings or signatures is a good approach.

If you want to detect activity using a method not already covered by the scanners, you'll want to implement a custom scanner.
