Why Fleet

What's it for?

In an industry that views security and IT as a shopping spree rather than a process, it's little wonder that IT and security teams get stuck with bolt-on solutions, misconfigured tools, and disparate workflows.

Fleet helps organizations like Fastly and Gusto reimagine the "easy button."

By simplifying how they do device health, FIM, HIDS, posture assessment, malware detection, vulnerability management, MDM, and the rest, Fleet's API enables teams with thousands of computers to build an IT and security program that works.

Out-of-the-box policies

Fleet includes out-of-the-box support for all CIS benchmarks for macOS and Windows, as well as many simpler queries.

Take as much or as little as you need for your organization.

Supported platforms

Here are the platforms Fleet currently supports:

  • Linux (all distros)
  • macOS
  • Windows
  • Chromebooks
  • Amazon Web Services (AWS)
  • Google Cloud (GCP)
  • Azure (Microsoft cloud)
  • Data centers
  • Containers (kube, etc)
  • Linux-based IoT devices

Lighter than air

Fleet is lightweight and modular. You can use it for security without using it for MDM, and vice versa. You can turn off features you are not using.

Open by design

Fleet is dedicated to flexibility, accessibility, and clarity. We think everyone can contribute and that tools should be as easy as possible for everyone to understand.

Good neighbors

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.

Free as in free

The free version of Fleet will always be free. Fleet is independently backed and actively maintained with the help of many amazing contributors.


The company behind Fleet is founded (and majority-owned) by true believers in 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 is public and open source. You can read about the history of Fleet and osquery and our commitment to improving the product.

Is it any good?

Fleet is used in production by IT and security teams with thousands of laptops and servers. Many deployments support tens of thousands of hosts, and a few large organizations manage deployments as large as 400,000+ hosts.
