  We study the Symmetry Topological Field Theory in holography associated with
4d $\mathcal{N}=1$ Super Yang-Mills theory with gauge algebra
$\mathfrak{su}(M)$. From this, all the bulk symmetry operators are computed and
matched to various D-brane configurations. The fusion algebra of the operators
emerges from brane dynamics. In particular, we show that the symmetry operators
are purely determined from the center-of-mass modes of the branes. We identify
the TQFT fusion coefficients with the relative motion of the branes. We also
establish the origin of condensation defects, arising from fusion of
non-invertible operators, as the consequence of tachyon condensation in
brane-anti-brane pairs.
