# Multi-Tenant Access Control and Organisation Management

> Nexenergie supports multiple organisations on a single platform. Learn how tenant isolation works and how to manage access within your organisation.

A tenant is an organization with its own users, sites, API keys, and webhooks. Data is scoped to the tenant on the access token or API key.

## Roles

Platform **superadmins** can list and deactivate tenants and users via `/api/v1/admin`. That is not a tenant role.
