​
Recovery- Enrich Non-Enriched Observables

This Workflow enriches observables that have not been enriched before. It does not re-enrich observables that are already enriched.

​
Recovery- Handle Unprocessed Alerts

This workflow attempts to reprocess alerts that were not fully processed, such as those affected by missing or incorrect templates. It is intended to be used as a recovery step if alert processing fails or after a missing or broken template has been added.
