Um VPN kill switch \u00e9 um recurso de seguran\u00e7a que corta sua conex\u00e3o com a internet no momento em que a conex\u00e3o VPN cai. Sem aviso, sem atraso \u2014 seu tr\u00e1fego para at\u00e9 que a VPN esteja de volta.<\/p>\n\n

Sem ele, uma desconex\u00e3o repentina da VPN exp\u00f5e seu endere\u00e7o IP real e tr\u00e1fego n\u00e3o criptografado a qualquer pessoa que esteja observando \u2014 seu provedor de servi\u00e7os de internet, a rede em que voc\u00ea est\u00e1 ou terceiros. O kill switch fecha essa lacuna automaticamente.<\/p>\n\n

\u00c9 um dos recursos de VPN mais pr\u00e1ticos que voc\u00ea pode ter, e funciona inteiramente em segundo plano.<\/p>\n\n

Como um VPN Kill Switch Funciona<\/h2>\n\n

Quando voc\u00ea usa uma VPN, todo o seu tr\u00e1fego flui atrav\u00e9s de um t\u00fanel VPN <\/a>criptografado para um servidor VPN. Seu endere\u00e7o IP real permanece oculto \u2014 o IP do servidor \u00e9 o que o mundo exterior v\u00ea.<\/p>\n\n

As conex\u00f5es VPN nem sempre s\u00e3o est\u00e1veis. Um solu\u00e7o no servidor, uma troca de rede ou uma breve queda de sinal podem interromper o t\u00fanel VPN sem que voc\u00ea perceba. Nesses segundos, seu dispositivo volta para sua conex\u00e3o de internet regular \u2014 desprotegido e exposto.<\/p>\n\n

O kill switch monitora sua conex\u00e3o VPN em tempo real. No momento em que a conex\u00e3o VPN \u00e9 perdida, ele bloqueia todo o tr\u00e1fego de internet. Ele permanece ativo at\u00e9 que a VPN se reconecte, e ent\u00e3o restaura sua conex\u00e3o automaticamente. Voc\u00ea n\u00e3o precisa fazer nada.<\/p>\n\n

Tipos de VPN Kill Switches<\/h2>\n\n

Os VPN kill switches dividem-se em dois tipos principais. Qual deles voc\u00ea precisa depende de como voc\u00ea usa sua VPN.<\/p>\n\n

Kill Switch ao n\u00edvel do sistema<\/h3>\n\n

Um kill switch de n\u00edvel de sistema interrompe todo o tr\u00e1fego de internet no dispositivo se a VPN cair \u2014 todos os apps, todos os navegadores, todos os processos em segundo plano. Nada passa sem a prote\u00e7\u00e3o da VPN.<\/p>\n\n

Esta \u00e9 a op\u00e7\u00e3o mais completa. Se a privacidade for importante em tudo no seu dispositivo, o VPN kill switch ao n\u00edvel do sistema \u00e9 a escolha certa.<\/p>\n\n

Kill Switch de N\u00edvel de Application<\/h3>\n\n

Um kill switch de n\u00edvel de aplicativo permite escolher quais apps ser\u00e3o bloqueados se a VPN cair. Todo o restante continua funcionando normalmente.<\/p>\n\n

Isso \u00e9 \u00fatil quando voc\u00ea deseja proteger uma atividade espec\u00edfica \u2014 um cliente torrent, <\/a>um aplicativo de mensagens, uma ferramenta de trabalho \u2014 sem interromper toda a sua conex\u00e3o. Seu navegador pode permanecer online enquanto um aplicativo sens\u00edvel fica offline at\u00e9 que a VPN seja reconectada.<\/p>\n\n

Ambos os tipos de kill switches protegem seu endere\u00e7o IP e dados. A diferen\u00e7a \u00e9 o escopo.<\/p>\n\n

Por que voc\u00ea precisa de um VPN Kill Switch<\/h2>\n\n

Um VPN kill switch \u00e9 essencial se voc\u00ea depende da sua VPN para mais do que uma navega\u00e7\u00e3o casual.<\/p>\n\n

As conex\u00f5es VPN caem. Isso n\u00e3o acontece com frequ\u00eancia com uma VPN confi\u00e1vel, mas acontece \u2014 problemas no servidor, Wi-Fi inst\u00e1vel, altern\u00e2ncia entre redes. Sem um kill switch, esses momentos de desconex\u00e3o deixam voc\u00ea exposto sem aviso pr\u00e9vio.<\/p>\n\n

Em Wi-Fi p\u00fablico, <\/a>essa exposi\u00e7\u00e3o \u00e9 imediata. Aeroportos, caf\u00e9s e hot\u00e9is operam redes abertas onde outros podem interceptar tr\u00e1fego n\u00e3o criptografado. Uma VPN com um kill switch mant\u00e9m seus dados protegidos mesmo se a conex\u00e3o falhar.<\/p>\n\n

Para o trabalho remoto, um VPN kill switch tamb\u00e9m \u00e9 importante. Muitas empresas exigem uma VPN para aceder a sistemas internos. Se a VPN cair a meio da sess\u00e3o, dados sens\u00edveis podem viajar brevemente atrav\u00e9s de uma liga\u00e7\u00e3o desprotegida. O kill switch evita isso.<\/p>\n\n

Uma VPN sem um kill switch oferece boa prote\u00e7\u00e3o na maior parte do tempo \u2014 mas n\u00e3o o tempo todo. O kill switch cobre as lacunas.<\/p>\n\n
