Defender ATP isn't really comparable to XProtect because it's providing your company with detailed logs of what's going on with the device - file operations, network connections, data about every program executed and the command line, and so on. That's why it slows down Homebrew so much, it's creating a ton of files every time you run it. Setting up exclusions for Homebrew's directories might help with performance, but I'd understand if they say no. Bad guys use Homebrew too.
