Agnitum Outpost Firewall is a powerful personal firewall that provides peace of mind from any threats by cookies, banner ads, e-mail viruses, backdoors, spyware, crackers, adware, and virtually any other Internet danger. Outpost starts protecting against all kinds of internal and external attacks as soon as it is installed. It offers an open architecture and support for plug-ins, so the capabilities can easily be extended by other developers. You can filter e-mails based upon their content, and Outpost will prevent dangerous attachments from executing. In addition, Outpost performs web filtering, detects port scanning and offers a privacy guard feature, as well as a plug-in that will block banner advertisements from your web pages. Inexperienced users will appreciate the ease of installation and ability to simply set Outposts protection features. An optional Pro version with additional features is also available (not free).
