In this talk, we review some recent advances in understanding the interplay between transverse momentum dependent gluon distributions on the one hand, and the saturation phenomenon at low $x$ on the other hand. Using the example of forward heavy-quark pair hadro- or leptoproduction, we argue that saturation corrections are needed to properly take the gauge-dependence and polarisation properties of the gluon distribution into account. Moreover, we give an outline of how nonlinear JIMWLK evolution can be combined in a consistent way with the resummation of Sudakov logarithms.
