Vectra XDR

>**NOTE:** This connector uses Azure Functions to connect to the Vectra API to pull its logs into Microsoft Sentinel. This might result in additional data ingestion costs. Check the [Azure Functions pricing page](https://azure.microsoft.com/pricing/details/functions/) for details.

>**(Optional Step)** Securely store workspace and API authorization key(s) or token(s) in Azure Key Vault. Azure Key Vault provides a secure mechanism to store and retrieve key values. [Follow these instructions](https://docs.microsoft.com/azure/app-service/app-service-key-vault-references) to use Azure Key Vault with an Azure Function App.

>**NOTE:** This data connector depends on a parser based on a Kusto Function to work as expected. Follow these steps for [Detections Parser](https://aka.ms/sentinel-VectraDetections-parser), [Audits Parser](https://aka.ms/sentinel-VectraAudits-parser), [Entity Scoring Parser](https://aka.ms/sentinel-VectraEntityScoring-parser), [Lockdown Parser](https://aka.ms/sentinel-VectraLockdown-parser) and [Health Parser](https://aka.ms/sentinel-VectraHealth-parser) to create the Kusto functions alias, **VectraDetections**, **VectraAudits**, **VectraEntityScoring**, **VectraLockdown** and **VectraHealth**.
