HowVPNsWork
WhenyouconnecttoaVPNserver,severalstepsoccurtoensureasecureandprivateconnection:
DataEncryption:YourdeviceencryptsoutgoingdatapacketsusingtheVPNprotocolandencryptionkeys.VPNTunnelEstablishment:EncrypteddatapacketsareencapsulatedwithinVPNtunnelingprotocolsandsenttotheVPNserver.VPNServerProcessing:Uponreceivingyourdata,theVPNserverdecryptsandprocessesitbeforeforwardingrequeststotheinternet.InternetAccess:TheVPNserverinteractswithwebsitesoronlineservicesonyourbehalf,maskingyourIPaddressandencryptingincomingdataforsecuretransmission.DataReturn:EncrypteddatafromtheinternetissentbacktotheVPNserver,encryptedagain,andtransmittedthroughthesecuretunneltoyourdevice.DecryptionandDisplay:Yourdevicedecryptsincomingdatapackets,allowingyoutoaccesswebsites,streamcontent,orperformonlineactivitiessecurely.
