About FwChange
FwChange is not a product written by people who read about firewalls. It was built from the field, after watching the same migrations fail the same preventable way. The software encodes a method already proven by hand.
The background
The method comes from hands-on work in the field: migrating firewall estates, rationalizing rule bases, and standing in front of auditors who want to know who changed what, when, and why.
The method draws on a dataset of hundreds of firewall migration projects spanning regulated and enterprise environments. Names stay anonymized; the patterns do not. The same preventable failures repeat at every scale: shadow rules nobody finds, manual translation errors between vendor syntaxes, and compliance evidence reconstructed under deadline because no system captured it as the change happened.
FwChange exists because those problems were being solved by hand, over and over. It encodes field-tested method into software, so the analysis that used to live in an engineer's head is now a step in the workflow.
What FwChange covers
FwChange is built for the environments where a wrong firewall rule is both a security incident and an audit finding. These are the frameworks and estates the platform is designed around.
Specialization
The work sits where regulated infrastructure meets multi-vendor firewall estates, the place where a wrong rule is both a security incident and an audit finding.
FwChange was born from one observation repeated across hundreds of projects: enterprise firewall migrations fail the same preventable way: undetected shadow rules, manual translation errors between vendor syntaxes, and compliance evidence that has to be reconstructed after the fact. The platform turns each of those into a step the software handles, not a thing a senior engineer has to remember.
The platform is the proof. The methodology page walks the thinking behind every part of it, the same reasoning proven in the field before any of it was code.
