# Customize Detections

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

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

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.
