| API | The REST API exposes host, task, multicast-session, image and system-information routes. | Warewulf includes a REST API that is disabled by default and can be configured to require TLS. |
| Installation | Installation is performed by cloning or downloading the repository and running installfog.sh as root. | The project documents RPM packages for Rocky Linux 9 and openSUSE Leap, plus source builds and Linux container builds. |
| Purpose | FOG Project is a free, open-source network computer cloning and management solution. | Warewulf provisions and manages stateless Linux clusters, most prominently for high-performance computing. |
| Security | The FOG Client documentation says client-server communications use public-key infrastructure and AES-256 encryption after an RSA-4096 key exchange. | Warewulf supports SELinux and offers asset-key checks, secure mode, optional TLS for runtime overlays, and Secure Boot with shim and GRUB. |
| Security limitation | PXE and TFTP are unauthenticated, so the project recommends isolating imaging on a trusted network. | By default, provisioning requests can be spoofed to download OS images and overlays, and the kernel and system image remain unencrypted even when TLS is enabled. |
| Support | Support is provided through a public forum, documentation, Discord and community resources. | Warewulf offers free documentation, Slack, and GitHub community resources, while commercial support is available through CIQ and SUSE. |

In their own words
FOG Project
FOG Project is a free, open-source system for cloning and managing networked computers. It captures and deploys Windows, Mac OSX and Linux distributions, including hardware-independent images that can be used across different computer models. The project also lists multi-site installations and remote management, provided the FOG server is publicly reachable. That server must run on Linux; recommended options include server-oriented LTS distributions such as Ubuntu, Debian, Rocky Linux or AlmaLinux. FOG recommends configuring client machines to PXE boot first so imaging tasks can be sent without visiting each computer. The FOG Client supports host registration, hostname changes, scheduled power management, snapin installation and user tracking, with client installation described for Windows, Linux and OSX. Client-server communications use public-key infrastructure and AES-256 encryption after an RSA-4096 key exchange. The security guide recommends firewall rules and protecting the MySQL database and captured image directory. Community support is available through forums, a wiki and IRC. The Linux client lacks the FOG Tray, Active Directory joining and PrinterManager. FOG Project is free for commercial use; community support is free.
