Comodo Free Firewall Alternatives

Comodo Free Firewall

Comodo Firewall is a personal firewall, a genre of security software that secures PCs by policing Internet traffic on an app by app basis. The most prominent feature of a personal firewall is generating popup notifications when an unknown program attempts to access the Internet for the first time. Doing so stops Trojan horses, botnets, hackers seeking remote access, malicious coin miners, and even shifty apps that transmit privacy-violating telemetry. But because of the popup notifications, this genre of security software has its fans and critics. Comodo Firewall helps reduce the number of popup notifications by identifying well-known and digitally signed apps.
Comodo Firewall also features host-based intrusion prevention (HIPS) and sandboxing. HIPS monitors apps for suspicious behavior like trying to inject themselves into other apps. This component offers increased security in exchange for reduced user comfort. Users must carefully assess the tradeoff before using it.
Sandboxing (known as Containment, Sandbox, and Virtualization in different versions) runs designated apps inside a sandbox, preventing permanent, irreversible changes to the system. If the app tries to change a file, the sandboxing system furnishes the said app with a copy of the file. The original file remains unchanged. Sandboxing is useful for testing apps.
