* [[Windows XP|Windows XP Service Pack 2]] has a limited integrated personal firewall, called the [[Windows Firewall]]. While considered to be better than no firewall at all, the Windows XP firewall offers no outbound connection protection; this lack of protection allows installed spyware and malware packages to create the outbound connections they need to communicate with the authors of such software. Microsoft has addressed this by adding outbound traffic blocking into the firewall for [[Windows Vista]], the next version of Windows which is due to be released in late 2006. It has been suggested that outbound blocking may be added in a future service pack for Windows XP, but Microsoft has not confirmed this as of January, 2006.

* [[Linux|Linux]] also has a built-in firewall, [[Netfilter/iptables]]. It is very powerful and extensible, supporting a system of plugin modules (for example, to enable autonomous handing of application layer protocols such as [[FTP]]). Netfilter/iptables is very widely used in the Linux platform. However, it is more focused on network filtering (inbound and outbound, for the computer as a whole) than on per-application filtering (granularly controlling which application can do what).

* [[Linux|Linux]] already have a build-in firewall, the [[Iptables|Iptables]]. It's very simple and powerful.
