I-SSL imele uLuhlu lweSokethi eKhuselekileyo: Indlela yokubamba ngesandla isetyenziselwa ukuqinisekisa ukungqinisisa okufanelekileyo phakathi kwabaxhasi kunye nezixhobo zeseva. Inkqubo yokuqinisekisa isekwe kubhalo oluntsonkothileyo apho izatifikethi, ezisebenza njengamaqhosha okubethela asele egcinwe kwicala lomthengi nakwiseva, zisetyenziselwa ukuqala unxibelelwano.
IPSec (Ukhuseleko lwe-IP): Le protocol inokusebenza kwimowudi yokuhambisa okanye kwitonela ukuze ikwazi ukwenza umsebenzi wayo wokufumana unxibelelwano lweVPN. Ezi ndlela zimbini zahlukile ngengqondo yokuba indlela yokudlulisa ibhala kuphela ukulayishwa kwedatha, okt ngumyalezo okwedatha kuphela. Imowudi yetonela ibhala yonke idatha ukuba ihanjiswe.
I-PPTP (Inkqubo yokuDlulisela kwiNqaku): Idibanisa umsebenzisi obekwe kwindawo ekude kunye neseva yabucala kwiVPN, kwaye ikwasebenzisa imowudi yetonela ekusebenzeni kwayo.
