The Armis Device connector gives the capability to ingest Armis Devices into Microsoft Sentinel through the Armis REST API. Refer to the API documentation: https://<YourArmisInstance>.armis.com/api/v1/docs for more information. The connector provides the ability to get device information from the Armis platform. Armis uses your existing infrastructure to discover and identify devices without having to deploy any agents. Armis can also integrate with your existing IT & security management tools to identify and classify each and every device, managed or unmanaged in your environment.

Tables Ingested

This connector ingests data into the following tables:

Table Transformations Ingestion API Lake-Only
Armis_Devices_CL ? ✓ ?

💡 Tip: Tables with Ingestion API support allow data ingestion via the Azure Monitor Data Collector API, which also enables custom transformations during ingestion.

Permissions

Resource Provider Permissions: - Workspace (Workspace): read and write permissions on the workspace are required. - Keys (Workspace): read permissions to shared keys for the workspace are required. See the documentation to learn more about workspace keys.

Custom Permissions: - Microsoft.Web/sites permissions: Read and write permissions to Azure Functions to create a Function App is required.
