Fleet
These files allow you to configure, patch, and secure computing devices for your organization.
Whether you're making changes by hand or spinning them up from Slack or Teams using a tool like Claude or Kilo Code (e.g. "Make our endpoints compliant with ISO 27001" or "Fix CVE-2026-XXXX"), your team reviews, merges, and it deploys to thousands of endpoints in seconds. This makes it straightforward to instantly rollback a change, and history is fully tracked.
You can read more about the anatomy of these files and what they do in Fleet's documentation. You can also opt to manage particular aspects of Fleet in the graphical user interface instead, such as software or labels.
