O que é uma VPN? E por que você deveria usar uma VPN, no acesso de Wi-Fi públicos?

Se você já parou pra pensar se um sinal de Wi-Fi público é seguro, você não está sozinho. De fato, de acordo com o relatório Norton Cybersecurity Insights Report, 6 em cada 10 consumidores acreditam que usar um Wi-Fi público tem mais risco de contaminação do que usar um banheiro público. E realmente tem. Navegar na internet ou realizar transações bancárias em uma rede de Wi-Fi não segura significa que você está tirando sua informação privada do anonimato e expondo ao risco. É por isso que uma rede virtual segura, mais conhecida como VPN, é obrigatória pra quem está preocupado com segurança online e privacidade.
O que é uma VPN?
Uma rede privada segura oferece privacidade e anonimato, criando uma rede privada dentro de uma conexão pública de internet. As VPNs mascaram seu endereço de protocolo de Intenet (IP) para que suas ações online sejam viltualmente indetectáveis. O mais importante: os serviços de VPN estabelecem conexões seguras e criptografadas garantidas para proporcionar uma privacidade até mesmo maior do que um Wi-Fi seguro.
Por que você precisa de uma VPN?
Pense em todas as vezes que você no seu dia-a-dia, lê emails em uma fila de uma cafeteria ou verifica sua conta bancária ao esperar em um consultório médico.
A menos que você estivesse conectado a uma rede Wi-Fi privada que requer uma senha de acesso, qualquer dado transmitido durante sua navegação estaria vulnerável à espionagem por estranhos usando a mesma rede.
A criptografia e o anonimato que a VPN proporciona protegem todas as suas atividades online: envio de emails, compras online ou pagamentos de contas. A VPN também ajuda a manter a sua navegação na internet anônima.
Além da Segurança
As VPNs, basicamente, criam um túnel entre a rede local e um nó de saída em outro lugar, que pode ser milhares de milhas de distância, fazendo com que pareça que você está em outro lugar. Este benefício da VPN se torna muito valioso para pessoas que moram em locais que censuram sites específicos. Isso permitirá que você continue aproveitando seus apps e sites favoritos de qualquer lugar do mundo, como se você estivesse em casa.
Como escolher uma VPN?
A melhor forma de estar seguro quando usar um Wi-Fi público é usar uma solução de VPN como a Norton WiFi Privacy, disponível para download. Aqui apresentamos algumas perguntas que você deve fazer ao escolher um provedor de VPN:
- Respeitam a sua privacidade? O objetivo de usar uma VPN é proteger a sua privacidade também. Eles devem ter uma política de curto prazo, o que significa que nunca vão rastrear ou registrar suas atividades online.
- Trabalham com os protocolos mais atuais? Uma VPN aberta fornece uma segurança mais forte do que outros protocolos, como o PPTP.
- Determinam limites? Dependendo do seu uso da internet, uma banda larga pode ser um fator decisivo para você. Assegure-se de que os serviços vão ao encontro do que você precisa, avaliando se você vai ter largura de banda total, ilimitada e sem limites de dados. Lembre-se, alguns pacotes podem não custar muito, mas você vai ser submetido a anúncios frequentes.
- Onde os servidores estão localizados? Decida quais locais de servidor são importantes para você. Se você quiser aparecer como se estivesse acessando a internet de um certo local, tenha certeza que há um servidor naquele país.
- Você será capaz de configurar o acesso da VPN em diversos dispositivos? Se você for como a maioria dos consumidores, você usa de 3 a 5 dispositivos diferentes. O ideal seria você estar habilitado a usar a VPN em todos eles, ao mesmo tempo.
- O que acontece se o sinal da VPN cair? Tenha certeza que o seu provedor executa um botão de desligar no sistema em caso de falhas. Isto significa que a sua conexão seria automaticamente bloqueada e não seria padrão para uma conexão de internet sem segurança, se algo der errado.
Há muitos pontos a considerar quando escolher um provedor de VPN, então faça sua lição de casa para ter certeza que você está adquirindo o melhor perfil para suas necessidades.
Independente de qual provedor você escolha, tenha certeza de que qualquer VPN fornecerá, de longe, muito mais privacidade e anonimato online do que qualquer Wi-Fi público jamais faria.

Yes, VPN is good, but very often even when you use VPN, it is possible to single out your real IP address. Before going online at work we check the anonymity via 2ip.io/privacy/ . The system will try to single out your real IP and if it doesn't - you can safely go online

I chat asked Norton about this and the answer is apparently NO, you have to purchase a Norton wi fi privacy vpn app for the vpn protection when using hotspots while traveling. At home you have vpn protection through your internet service. That's $29... extra a year per device currently. And it is for Apple and Android only platforms.

If I plan on replacing it, how can I tell in advance what mobile is compatible with Norton products?
Thanks.
missouri59 replied on Link permanente
I would go to Norton chat on
I would go to Norton chat on your account before you replace anything to see what they actually cover. Because it is a lot of money for these devices only to find they are not compatible like the fire tablets. I do not get why a Norton person has not answered any of the questions on this site- so I use the chat option n my account. Currently Norton is supporting android and apple products however not many amazon fire. And google stuff does not work on fire.

At the moment, I'm online at home, however, I have gone to the main branch library and church with my laptop and it would be great to use the WiFi access without wondering if someone is piggybacking of my signal and looking at my laptop's contents. I like this VPN. I'll get it installed the next time I renew Norton on my laptop.

I use ExpressVPN. I did a lot
I use ExpressVPN. I did a lot of research on VPNs and this one was given the highest marks. It works very well for me, and you can put it both on your phone and on your laptop. It is a paid service; for 12 months, it's $9/month. Well worth it. Norton's new product is only half a loaf. And we're all still waiting for some Nortonite to respond to all these messages. If Norton were really all that concerned about your laptop's security, they would at least give you some useful information about how to do that, if they do not have such a product themselves. And why don't they? Beats me. ExpressVPN does the trick.
A fun aside: I'm what's called a "Russia hand." I managed a lot of our science cooperation with the USSR and later. 20 years ago, I met a very nice Russian couple in Moscow who were both computer programmers who told me that they worked in a secret facility (the Russians call it a "yashchik," literally a "post office box"). They had a dog. They named the dog "Norton." I actually thought that was a pretty good endorsement for Norton and I've used it ever since. But then again, there's that dog. What were they thinking? Go figure.

If a WiFi connection at a hotel is secure, would I still need the Norton WiFi Privacy or would the secure connection at a hotel be enough security to be able to type in sensitive data, such as passwords and credit card information? Also, if a hotel does have a secure connection, does this mean that the hotel is using a VPN? Thank you.

Hi MissPiglet,
Hi MissPiglet,
Hotel Wi-Fi is risky. Read this blog for some Wi-Fi tips to stay safe while traveling: Your Summer Vacation Guide to Mobile Device and Public Wi-Fi Security. Your best bet would still be to use a VPN, even if your hotel says their Wi-Fi is "secure". Hope you enjoy your travels!

I'm unable to send emails on my iphone6+ when the Nortons WiFi privacy app is on. I can receive emails and use the Internet but can't send any emails it stays in the outbox. I have done a live chat, had a phone call and neither could help and was advised to ask question here.

I think the reason is: Your Internet service provider does not agree an another SMTP as his.

How to prevent android apps
How to prevent android apps going online before Norton VPN makes a secure tunnel?
(on my android every time I switch-on the "wifi", during the time needed to Norton VPN to build up the tunnel, I can clearly see all my apps notifications appear, which means... a lot of traffic has been exchanged "in clear"!!)
PS:
I'm not the only one to have detected this failure, please also refer to https://community.norton.com/en/forums/how-prevent-android-apps-going-online-norton-vpn-makes-secure-tunnel
