How VPN Works

A Virtual Private Network (VPN) is typically used to allow an employee access to a secure corporate network.

However, with the Riseup VPN, we use the same technology to allow everyone greater security when accessing the public internet. This type of VPN is called a personal VPN.

A normal internet connection

In a normal internet connection, all your traffic is routed from your computer through your ISP (Internet Service Provider) and out onto the internet and finally to its destinate. At every step of the way, your data is being recorded and is vulnerable to man-in-the-middle attacks (the danger of this is much less if you are using a secure protocol like https).

An internet connection with personal VPN

With a personal VPN, your traffic is encrypted on your computer, passes through your ISP and on to the VPN Server. Because the data is encrypted, your ISP has no knowledge of what is in your data that they relay on to the VPN Server. Once your data reaches the VPN Server, it is decrypted and forwarded on to its final destination.

With the personal VPN, if your data is not using a secure connections then it is still vulnerable from the point it leaves the VPN Server. However, by routing your data through the VPN server, you have acheived two important advantages:

  • Your data is protected from blocking, tracking, or man-in-the-middle attacks conducted by your ISP or network operators in your local country.
  • Your data now appears to use the IP address of the VPN server, and not your real IP address. Most websites gather and retain extensive data base on this IP address, which has now been anonymized.

Personal VPN anonymizes your connection

Because your traffic appears to originate from the VPN Server, the recipient of your network communication does not know where you actually reside (unless, of course, you tell them).

In the case illustrated above, the website in California thinks that the laptop in Brazil, the laptop in Europe, and the giant cellphone floating over Canada are all coming from New York, because that is where the VPN server is.

Limitaciones en el uso de RiserupVPN

El VPN de Riseup comparte algunas limitaciones comunes a todos los VPNs personales:

  • Una conexión no segura será todavía insegura: Aunque Riseup VPN conseguirá anonimizar tu ubicación y te protegerá de la vigilancia de tu ISP, una vez que tus datos son enviados de forma segura a través de estos saldrán a Internet como lo harían normalmente. Esto significa que debes seguir utilizando TLS cuando esté disponible (es decir: https, imaps, etc).
  • Riseup VPN no es la panacea: Aunque VPNs logra mucho, no puede arreglarlo todo. Por ejemplo, no puede aumentar tu seguridad si el equipo ya está comprometido con virus o spyware. Si proporcionas información personal a un sitio web, es poco lo que una VPN puede hacer para mantener tu anonimato en ese sitio web o sus socios. Para obtener más información, consulta Anonimato VPN.
  • Tu conexión podría ir más lenta: Riseup VPN redirige todo tu tráfico a través de una conexión cifrada a antes de su viaje hacia la Internet normal. Este paso adicional puede ralentizar las cosas. Para minimizar este contratiempo, puedes elegir un servidor VPN cercano a donde vivas.
