Kudalwa umhubhe ovikelwe. Uhlelo lwakho lwe-VPN neseva ye-VPN benza "ukuxhawulana" ukuze basungule uxhumano oluphephile, oluvikelwe besebenzisa iprothokholi ye-VPN.
Ithrafikhi yakho igeleza ngomhubhe. Sonke isicelo — iphepha le-web, isitokwe sevidiyo, ukulanda ifayela — sivikelwa ngaphambi kokuphuma kudivayisi yakho futhi siphumelele eseva ye-VPN.
Iseva ye-VPN ithumela isicelo sakho. Iwebhusayithi ibona ikheli le-IP leseva ye-VPN, hhayi elakho. Impendulo ibuyiselwa eseva ye-VPN, ivikelwe futhi, futhi ithunyelwe kuwe.

Cabanga kanjena: Cabanga ukuthumela incwadi. Ngaphandle kwe-VPN, noma ngubani ophatha incwadi angayifunda futhi abone ikheli lakho lokubuya. Nge-VPN, incwadi isebhokisini elikhiyiwe, futhi ikheli lokubuya ibhokisi le-P.O. — hhayi ikhaya lakho.

Uyafuna ukuhlola ukuthi i-VPN yakho iyasebenza yini? Sebenzisa i-IP Lookup, i-DNS Leak Test, ne-WebRTC Leak Test yethu ukuqinisekisa ukuthi uxhumano lwakho lungelwemfihlo ngempela.

Imibuzo Ebuzwa Kaningi

Yini i-VPN ngamagama alula?

I-VPN (Inethiwekhi Yangasese Yenkulumombono) iwusizo olubethela uxhumano lwakho lwe-inthanethi futhi lulukhombisa ngeseva endaweni oyikhethile. Cabanga ngayo njengomhubhe oyingxenye yenethi ophephile, oyimfihlo phakathi kwedivayisi yakho ne-inthanethi. Ngaphandle kwe-VPN, i-ISP yakho ingakwazi ukubona yonke iwebhusayithi oyivakashelayo, futhi amawebhusayithi angakwazi ukubona ikheli lakho elingempela le-IP nendawo eyisilinganiso.
