Comodo Internet Security vs Gufw

Comodo Internet Security is a Windows security suite that combines antivirus protection, a packet-filtering firewall, host intrusion prevention, and automatic isolation for unknown files. Its Auto Sandbox runs unfamiliar files in a separate environment. The firewall can block unauthorized inbound and outbound connections, manage which programs can access the internet, and hide computer ports. Secure Shopping isolates browser sessions and includes keylogger prevention, screen-capture blocking, and SSL certificate inspection; it can also run applications such as email clients, password managers, spreadsheets, and VPN clients in that environment. The product describes cloud antivirus scanning, behavior analysis, and whitelisting, alongside malicious-website filtering with custom block lists. Comodo lists a free plan and paid plans from $29.99/yr. Its guide lists Windows 10, 8, and 7, and says versions 12.0.0.6882 and later do not support Windows XP or Vista. Support resources include Comodo Support, an online help guide, and a user forum.

Gufw is a free, GPL-3.0 graphical interface for Ubuntu’s Uncomplicated Firewall, or UFW. It lets users configure TCP and UDP port rules with Allow, Deny, Reject and Limit actions. Enabling the firewall sets incoming traffic to Deny and outgoing traffic to Allow by default, while UFW’s preconfigured programs and services simplify rule creation. Gufw is Linux software and an on-premises tool described by Ubuntu documentation as suitable for beginners. Installation uses the gufw package from the Universe repository. Gufw 14.10 or later can show a Routed option for forwarding rules when IP forwarding is configured. Version 13.10.2 or later supports remote use through an exported X display. The Ubuntu guide warns that enabling the firewall over SSH before adding an SSH rule can close the connection. No paid plans or usage limits are stated, and no multi-vendor support is listed.
