Iyabona ikheli lomthombo elifikayo, futhi ingase isebenze ngekheli, inethiwekhi yokubamba engemuva kwayo, isifunda, inkampani yenethiwekhi noma izimpawu ezihlobene ne-akhawunti nedivayisi. Akukho kulokho okuwubunikazi obuhlukile, futhi ukwabelana ngamakheli kwenza ukuvinjelwa okuhambisana nakho kube yinto evamile: ikheli elilodwa elilinganiselwe lingakhipha abasebenzisi abangahlobene ngemuva kokuhunyushwa okufanayo.

Thola ikheli ngendlela efanayo esetshenziswa uhlelo, hhayi kusiphequluli sekhompyutha ephathekayo. Ocingweni, isicelo esilula ensizakalweni yokuphindaphinda ikheli sibonisa lokho ohlangothi olukude okutholayo, futhi ukuqhathanisa nalokho nesicelo esihamba ngenethiwekhi yeselula kukutshela ukuthi ikheli lashintsha noma cha.

Uma uhlelo lusebenza ngenethiwekhi yeselula futhi lwehluleka ngomhubhe nge-akhawunti efanayo, ukwenqaba kusekuqeleni okukude noma kunqubomgomo yohlelo uqobo. Uma lwehluleka kukho kokubili, i-VPN ayisiyo umehluko futhi kufanele uyeke ukuhlola izindawo zokugcina.
