We study the constraints of superconformal symmetry on 4d N=4 theories in the presence of a defect from the point of view of the bootstrap. The superconformal algebra implies that the bootstrap equations have an exact truncation which is tractable analytically. Due to a surprising connection between superconformal blocks, these results apply both to conformal interfaces and to line defects. Moreover, the truncated equations are polynomial and in general solvable, which allows to extract analytic non-perturbative resuls for the CFT data.
