Extensions of the Standard Model are required to explain new physics phenomena, such as Dark Matter, the Baryon Asymmetry of the Universe, and neutrino masses. These extensions are typically accompanied by a number of new particles and additional parameters. While the introduction of such particles and parameters can explain the observed phenomena, they also affect observables that have been measured with high precision in experiments. To identify viable regions of parameter space that are relevant for experimental searches, efficient scanning tools are essential. Such tools must consistently incorporate all relevant theoretical and experimental constraints. We present here a newly developed framework, called NMSSMScanner, which interfaces BSMArt, NMSSMCALC, HiggsTools, HPAIR, SusHi, RelExt, PYTHIA, and SModelS. As an illustration of its capabilities, we use NMSSMScanner to determine the maximal viable di-Higgs production cross sections in the NMSSM.
