A virtual network implemented by one or more processors executing computer instructions, the virtual network comprising: a web application firewall, WAF, portion to receive network traffic for one or more other portions of the virtual network; a first firewall connected to the WAF portion; a web server portion, connected to the first firewall, to receive web traffic, the web server portion including a customer portal server; a second firewall connected to the web server portion; an application server portion, connected to the second firewall, to perform application services for one or more servers of the web server portion, the application server portion including a set of application servers; a third firewall connected to the application server portion; a database server portion connected to the third firewall, the database server portion including a set of database servers accessible by one or more application servers of the set of application servers; a fourth firewall connected to the database server portion, the application server portion, and the web server portion; an active directory portion, connected to the fourth firewall, to perform authentication of one or more access requests associated with the virtual network; and a utility portion, connected to the fourth firewall, including a set of security utilities for other portions of the virtual network,. the utility portion further comprising: a virtual network link between the utility portion and a utility virtual network, the utility virtual network including the set of security utilities, the virtual network link facilitating utilization of the set of security utilities by the other portions of the virtual network, where the application server portion further comprises: a virtualized firewall device allocated as a computing resource of the application portion, the virtualized firewall device being different from and separate to the first to fourth firewalls, the firewall device being configured to selectively filter a portion of network traffic directed to the application server portion; and where an application server, of the set of application servers, is configured to receive an application request from a server of the web server portion and generate a database request for a database server of the set of database servers. a web application firewall, WAF, portion to receive network traffic for one or more other portions of the virtual network;
