I-NSEN ilandela ngokungqongqo iinkonzo zokulungisa zasimahla, ukutshintshwa kwasimahla kunye nokubuyiselwa kwasimahla kwiinyanga ezili-18 emva kokuba ivalvu ingasebenzi okanye iinyanga ezili-12 emva kokufakwa nokusetyenziswa kwipayipi emva kokusebenza kwangaphambili (ekuza kuqala). 

Kwimeko apho ivalvu iye yawa ngenxa yengxaki yomgangatho ngexesha lokusetyenziswa kwipayipi ngexesha lewaranti yomgangatho, i-NSEN iya kubonelela ngenkonzo yewaranti yomgangatho yasimahla. Inkonzo ayizukuphela de kube ukusilela kulungisiwe kwaye ivalvu iyasebenza kwaye umthengi utyikitye ileta yokuqinisekisa.

Emva kokuphela kwexesha elichaziweyo, i-NSEN iqinisekisa ukubonelela abasebenzisi ngeenkonzo zobugcisa ezisemgangathweni ngexesha nanini na xa imveliso ifuna ukulungiswa nokugcinwa.
