Backconnect Proxies or Reverse Proxies as they are also called are used to retrieve content from one or more websites through proxy servers on behalf of the client. These servers can either be set or can be auto-rotated by automatically switching to a different server every time content is accessed. As such, the chances of getting blocked from a particular site is reduced.
Some other benefits of using Backconnect proxies include better protection from internet attacks and a simplified means of monitoring traffic flow coming to your servers. Anyone trying to connect to the target websites will first have to go through the Backconnect proxies, though this fact does not even register to the user. As far as the user can tell, they are simply visiting the servers directly.
One of the biggest reasons for why customers get Backconnect proxies is for the purpose of protecting sensitive data. Owners of the data and credentials will move the information to internet networks and the proxy will then be deployed to control access to the servers. This can help increase security by limiting exposure of things like payrolls, secret designs and such from unwanted eyes.
