Prowler authenticates to Scaleway using a Scaleway API key (access key + secret key). The integration is read-only and only needs permission to list IAM users and API keys in the audited organization.

Prerequisites

  1. A Scaleway organization with IAM access.
  2. A Scaleway API key with at least the IAMReadOnly policy bound to a dedicated IAM user (do not use the account root user).
  3. Your organization ID (visible at the top right of the Scaleway console).

Authentication Method

Prowler reads credentials exclusively from the standard Scaleway environment variables. There are no credential CLI flags, so secrets are never exposed in shell history or process listings. The scope variables can also be passed as CLI flags (--organization-id, --project-id, --region), which override the corresponding environment variables.

Required Scaleway Permissions

The API key bearer needs read access to the IAM API in order to list users and API keys. The IAMReadOnly policy is sufficient. Refer to the Scaleway IAM policy reference for the full list of permissions.
