Sterile neutrino dark matter, which remains a popular alternative to the WIMP paradigm, has generally been studied in non-supersymmetric setups. In this talk, we investigate dark matter properties of the sterile neutrino within an underlying theory that is supersymmetric, which demonstrates several interesting and novel features such as multiple populations from multiple production mechanisms and significant contributions to the effective number of relativistic degrees of freedom. We will also briefly discuss how dark matter considerations can shed light on the scale of supersymmetry.
