I install Docker Desktop through Homebrew on my work Mac, but macOS occasionally removes it or leaves it missing after an update. I have not experienced this on my personal Mac. Could Gatekeeper, Homebrew's cask upgrade process, disk-space problems, or a company device-management policy be responsible?

The most likely explanation is your company’s device-management software. Work Macs often have MDM rules that remove applications which are unapproved or have licensing restrictions. Docker Desktop’s business licensing could be one reason it is blocked. Check the installed management profiles or ask your IT team whether Docker Desktop is permitted.
Docker Desktop can consume a lot of disk space because images, containers, and volumes are commonly stored in a large virtual disk file. If the disk becomes full or that file is corrupted, Docker may fail to start or need to recreate its data. Check available storage and Docker’s disk-image settings.
That usually explains Docker failing to launch rather than the application bundle vanishing, so I would still investigate company management and Homebrew first.
Homebrew could also be involved. During a cask upgrade it may move the existing application aside and then fail while downloading or installing the replacement, making Docker Desktop appear to have been deleted. Check the Homebrew output and logs from the time it disappeared before assuming macOS removed it.
If Docker Desktop is not required, alternatives include Colima or another Linux virtual machine running Docker. Colima works well for many command-line workflows, although its Docker socket path differs from Docker Desktop and some containers may need extra configuration. Apple’s native container tooling is another option, but it is not a complete drop-in replacement for every Docker Compose setup or image.
Even if you cannot see an obvious policy, IT may be enforcing it through a security or software-inventory tool rather than a visible application setting.
