Comodo Firewall Review

Fernando Ortega
A highly rated and essential firewall distributed as freeware
A review of Comodo Firewall by Fernando Ortega

Comodo Firewall is one of the best free firewall of our days that is capable to efficiently protect the operating system against hackers and malicious programs.

The application completely controls all applications that run on the computer and the network activity, blocks malware before they can access the computer by using Prevention-based security and displays personalized alerts (remembers which software is trusted and allowed and displays alerts in case of unknown connection attempts).

The Firewall creates and uses application rules to control all connection attempts, blocks unauthorized or malicious attempts of applications to send or receive information from the Internet, manages the list of trusted applications and enables Port Stealthing (to hide the computer from port scans).

Users can view the list of active connections (applications that are currently connecting to the Internet with details such as IP addresses, ports, protocols and the traffic level of connections), manage the list of blocked addresses and network zones (the communication with these networks can be restricted or blocked entirely).

Experienced users can customize the Network Security Policies (manages application and global rules), Predefined Firewall Policies (network control rules that can be shared by more than one application) and Firewall Behavior Settings (to customize the firewall security level and the alert frequency level).

Defense is a basic component of the security software that enables host intrusion prevention, monitors the activities of executables, alerts the user in case an unknown application attempts to run itself, protects against data theft, computer crash, system damage, rootkit, keylogger attacks and inter-process memory injection.

Defense also blocks viruses, trojans and spyware before these can infect the operating system, prevents any unauthorized malicious modification of the system settings, uses a sandbox to launch particular applications in a safe isolated environment and has a fully customizable interface.

Comodo Firewall automatically checks for new updates, detects new private networks, enables password protection of the product settings, generates logs and is available in multiple languages.

Finally, Comodo Firewall offers maximum protection and full control of applications and network connections, displays easy to understand informative alerts, has a fully customizable interface, enables personalized protection based on user choices and consumes low system resources.
