  We precisely reproduce the perimeter law obeyed by Wilson loops on large
spatial contours in planar N=2 SYM at strong coupling, as recently deduced
using localization, by means of a dual holographic model. The relevant
supergravity background is sourced by D5-branes wrapped on a two-sphere in a
Calabi-Yau two-manifold. Thus, localization and holography are cross-checked,
for the first time, in a non conformal context where the gravity background is
not asymptotically Anti de Sitter and the dual gauge theory has a
logarithmically running coupling. We also notice that the same cross-check can
be performed considering an alternative holographic description of N=2 SYM
based on a background sourced by fractional D3-branes.
