We present a supersymmetric extension of the Standard Model which originates from a $10D$, $\mathcal{N}=1$, $E_8$ gauge theory. The transition to four dimensions occurs after the dimensional reduction of the theory over the $SU(3)/U(1)\times U(1)\times\mathbb{Z}_3$ space. Making use of the Wilson flux breaking mechanism, the resulting $4D$ theory is an $\mathcal{N}=1$, $SU(3)^3$ Grand Unified Theory with two $U(1)$s. After the symmetry breaking of the trinification gauge group, the model is viewed as a split-like supersymmetric version of the Standard Model with an extra gauge singlet that reminds of an NMSSM configuration. A preliminary 1-loop analysis shows great promise, predicting the unification (and first supersymmetry breaking) scale at $\sim 10^{15}$ GeV with no proton decay
and the (second) supersymmetry breaking scale in the region of a few TeV.
