Understanding Circuit-Level Gateway Firewalls

In my previous article, I have started discussions on the different types of firewalls that we can have in organizations. In this article, I want to continue that discussion by talking about circuit-level gateway firewalls. Follow me as we look at that together in this article.


Circuit Level Gateway firewalls are similar to application gateways but are more secure and generally implemented on high-end equipment. These type of firewall also employ users authentication but they do so earlier in the process. 


With an application gateway, first and the client application is checked to see if access could be granted, and then the user is authenticated. With circuit-level gateways, authenticating the user is the first step. The user’s login ID and password are checked and the user is granted access before the connection to the user is established. This means that every individual, either username or IP address, must be verified before any further communication can take place.
