What is the difference between ATD-Guard and a firewall?



A firewall is blocking incoming connections from the network *. ATD-Guard blocks outgoing connections initiated by an executable installed on your computer. It can be your browser when you connect to a website but also an application that transmits data without necessarily knowing it. The most common case of this type is checking for updates. Many software vendors use this type of connection to track the usage of their applications. Even if this does not seem very serious to you, you warn the software publisher each time you launch its application. You can legitimately think that it is none of his business. In some cases the transmission does not stop there and a lot of personal information can be collected and transmitted. This is the case with so-called spyware applications. The firewall does not protect you from this type of transmission. Besides, you have never seen an alert from your firewall because software was checking for available updates.


* A firewall mainly concerns local business networks with often client-server infrastructures. Computers connected behind routers (internet boxes) are normally not very affected by this type of problem except configuration of a port-forward on the router or particularly violent network virus on one of the connected computers if there are several. . The firewall therefore remains useful on any computer. ATD-Guard and the firewall each have their own area of ​​application. One does not replace the other.
