São Grátis Proxies Seguro para usar em 2023?- Informações importantes
pós-título

We here at ProxyScrape have been providing a free proxy list for quite a while now, but admittingly we have to say that free proxies aren’t always safe to use. This is because free proxies do not always provide the anonymity you did expect while browsing the internet and might be malicious. They can be malicious in various ways, such as by injecting ads, tracking your activities, and logging your data such as phone numbers, emails, and location.

In most cases, you will be better off with alternatives such as datacenter proxies or residential proxies, which are maintained by professionals with no malicious intent.

In this article, we will go more in-depth into how public proxies might be unsafe to use.

Proxy anonymity levels

For some people, proxy anonymity matters a great deal because they do not want their original identity revealed.

Há três tipos de níveis de anonimato:

  • Transparent proxy: does not hide your IP Address.
  • Anonymous proxy: hides your IP address but does reveal that you are using a proxy server.
  • Elite proxy: hides both your IP address and the fact that you are using a proxy server at all.

Transparent proxies are a significant problem when it comes to free proxies, especially with HTTP proxies. Analytics on the public HTTP proxies that we have checked show that at least 55% of the proxies are transparent. Transparent proxies will show your original IP address to the target. 6% of the public HTTP proxies are anonymous and will show to the target that you are connected via a proxy. Only 39% of the shared proxies are elite and will not reveal any traces to your target that you are hiding behind a proxy.

When you want to stay anonymous, make sure to only use elite proxies!

Traffic manipulation & modification

People who host a proxy can modify the content you see when visiting a website. These modifications can be malicious.

Research shows that 38.21% of all HTTP proxies perform some sort of content modification. Luckily only 5.15% are malicious.

Traffic manipulation & modification ofpublic proxies

Formas de modificação de conteúdo proxy não maliciosa:

  • Bloqueio de anúncios e rastreadores
  • Caching do site

Formas de modificação maliciosa do conteúdo proxy :

  • Injetando ou substituindo propagandas
  • Collecting user information such as location, email, phone number
  • Rastreamento de mouse/teclado
  • Rastreamento com cookies
  • Solicitação de sites inseguros

Quando você usa um site público proxy, você deve ficar ciente de que o proxy que você está usando pode estar modificando o que você vê no site. Algumas das modificações que o proxies faz podem ser mais maliciosas do que outras.

Additional problems with public proxies

Public proxy lifespan

As you already know, public proxies get used by a tremendous amount of users; this causes a lot of load on the proxy servers. Research done by the University of Washington estimates that each public proxy could be using up to 300 MB of data per second. As a result, most open proxies’ lifespan is very short since it is very resource-intensive to operate one. It is estimated that the median lifespan of a free proxy is only seven days long.

Blacklisting of public proxies

Outro grande problema com o público proxies é que eles são colocados na lista negra muito rapidamente a partir de sites conhecidos.

Há duas razões principais para isso:

  • Os sites utilizam um serviço para detectar o uso de proxy . Como o proxies é público para todos, isto é muito fácil de detectar. Os sites podem fazer isso com serviços como o MaxMind.
  • O proxies é muito usado para o site por outras pessoas, e elas são impedidas de acessá-lo.

Since free proxies are blacklisted quickly from many targets, they may not be of great use to you, and you might want to look at their alternatives.

Alternatives to free proxies

Since free proxies aren’t the best choice most of the time, what should you choose? It, of course, depends on your use-case.

Há dois tipos principais de outras categorias proxy :

  • Datacenter proxies: maintained by professionals in a datacenter
  • Residential proxies: residential IPs combined in a proxy network

Quando você deve usá-los?

When you should choose datacenter proxies

When you should choose datacenter proxies

Datacenter proxies are maintained by professionals and generally have a faster response time and greater bandwidth than their alternatives.

A maioria dos fornecedores do datacenter proxy precificam seus serviços pelo número de proxies que você compra em vez de pelo tráfego que consome.

Here are some scenarios you should consider datacenter proxies:

  • Your target is very unlikely to ban you quickly on a specific IP address.
  • You use a lot of traffic and have a limited budget. Datacenter proxies often come with unlimited or cheaply priced traffic.

When you should choose residential proxies

When you should choose residential proxies

Residential proxies are the more expensive and are often priced by the amount of traffic you consume, but you are less likely to be banned.

Você deve escolher residencial proxies em um dos seguintes cenários:

  • Seu site alvo o proíbe rapidamente quando o tráfego de bot é detectado.
  • Seu tempo é valioso, e você não pode se dar ao luxo de ser bloqueado por muito tempo.
  • Você precisa proxies de um país ou cidade específicos que não são fornecidos pelo datacenter proxies.

Outras vantagens do residencial proxies:

  • Você tem acesso a um pool de milhões de endereços IP em todo o mundo.
  • Seu alvo não sabe que você está usando um proxy, e pensa que você é um usuário regular.

Conclusão

In most cases, we would suggest against using free public proxies and go with alternatives like datacenter proxies or residential proxies instead. The reason being that most free proxies are not safe is because they are either not anonymous or are performing something malicious with your browsing activity.
