I'm not aware of any security advantages compared to npm. But one thing that comes to mind is that a while ago npm, by default, did not generate lock files, which is very much a risk concerning deployment and dependency-management in general. It's not an issue any longer, though, both yarn (yarn.lock) and npm (package-lock.json?) generate lock files by default.
