Organizations like Fastly and Gusto use Fleet for vulnerability reporting, detection engineering, device management (MDM), device health monitoring, posture-based access control, managing unused software licenses, and more.
Fleet includes out-of-the box support for all [CIS benchmarks for macOS and Windows](https://fleetdm.com/pricing), as well as many [simpler queries](https://fleetdm.com/queries).
Take as much or as little as you need for your organization.
Fleet is dedicated to flexibility, accessibility, and clarity. We think [everyone can contribute](https://fleetdm.com/handbook/company#openness) and that tools should be as easy as possible for everyone to understand.
Fleet has no ambition to replace all of your other tools. (Though it might replace some, if you want it to.) Ready-to-use, enterprise-friendly integrations exist for Snowflake, Splunk, GitHub Actions, Vanta, Elastic Jira, Zendesk, and more.
Fleet plays well with Munki, Chef, Puppet, and Ansible, as well as with security tools like Crowdstrike and SentinelOne. For example, you can use the free version of Fleet to quickly report on what hosts are _actually_ running your EDR agent.
While most folks prefer to use one or the other, Fleet can also coexist peacefully with Rapid7 and other agent-based vulnerability scanners. This can be useful during migrations.
The free version of Fleet will [always be free](https://fleetdm.com/pricing). Fleet is [independently backed](https://linkedin.com/company/fleetdm) and actively maintained with the help of many amazing [contributors](https://github.com/fleetdm/fleet/graphs/contributors).
The [company behind Fleet](https://fleetdm.com/handbook/company) is founded (and majority-owned) by [true believers in open source](https://fleetdm.com/handbook/company/why-this-way#why-open-source). The company's business model is influenced by GitLab (NYSE: GTLB), with great investors, happy customers, and the capacity to become profitable at any time.
In keeping with Fleet's value of openness, [Fleet Device Management's company handbook](https://fleetdm.com/handbook/company) is public and open source. You can read about the [history of Fleet and osquery](https://fleetdm.com/handbook/company#history) and our commitment to improving the product.
<!-- > To upgrade from Fleet ≤3.2.0, just follow the upgrading steps for the earliest subsequent major release from this repository (it'll work out of the box until the release of Fleet 5.0). -->
