Comodo Personal Firewall is one of the most powerful and smartest personal firewalls you can ever see. Introduced into the market just in March 2006. Comodo's Personal Firewall quickly gained a reputation as a high quality firewall suitable for both home users and corporate networks. It features both inbound and outbound packet filtering in combination with robust outbound application filtering at the network layer. The new-look interface facilitates quick and easy access to all major settings, including the powerful and highly configurable security rules interface.

While providing answers to firewall’s questions, users usually do not understand the complex questions which involve complicated connection details like IP addresses, Ports, Application paths etc. Comodo Personal Firewall helps you to understand what is going on by analyzing each alert and providing you an intuitive, easily understandable Security Considerations section with each question it asks.
With its built-in application database, Comodo Personal Firewall classifies more than 10.000 applications according to their risk level such as SAFE, SPYWARE, ADWARE etc. It is the only personal firewall which has such a big application database and which uses such a database to analyze the security risks.
