PYFRC2G

Summary from the TLDR InfoSec newsletter

PyFRC2G converts pfSense and OPNSense firewall rules into graphical flow diagrams and PDF documentation through API-based alias retrieval, automatic interface detection, and per-interface output generation with color-coded visualization. The tool implements smart change detection using MD5 comparison to regenerate graphs only when rules change, generates separate CSV and PDF files for each interface using Graphviz, and supports optional CISO Assistant integration for automatic upload of compliance evidence. Security teams can use PyFRC2G to visually document complex firewall rule sets and meet IT security compliance requirements across various frameworks without manual configuration files.
