TrueNAS is network-attached storage software from iXsystems, Inc., which does business as TrueNAS. It is installed on the customer's own hardware to provide network storage. A Community Edition is offered for testing in one's own environment, and Enterprise editions come with 24/7 support. The vendor describes an open-core model in which critical code is visible and tested. The open-source middleware on GitHub is licensed under LGPL-3.0, while the Enterprise edition is governed by an end-user licence agreement, so the product as a whole is not classed as open source.
iXsystems is headquartered in Campbell, California, United States. No majority owner or parent company is named. Because the software runs on the organisation's own servers, data stays on infrastructure the organisation controls, and no vendor-operated hosting region is named. For a European organisation the main considerations are the vendor's US jurisdiction, the proprietary terms of the Enterprise edition, and the ability to audit the open components, which the vendor itself emphasises.
