On firewall change failure modes
“After 280 enterprise migrations, the failure modes are predictable: shadow rules, manual translation errors between vendor syntaxes, and ownership gaps. None of these are technology problems — they are process and tooling problems. FwChange exists because the same preventable failures kept appearing across DAX-30 clients.”
— Nicholas Falshaw, Founder, FwChange
On AI in firewall management
“AI in firewall management is mostly marketing. The genuinely useful application is rule-base analysis: shadow detection, redundancy identification, and policy drift — pattern matching at scale. Anything claiming to autonomously approve changes against compliance frameworks is selling risk, not security.”
— Nicholas Falshaw, Founder, FwChange
On NIS2 and mid-market readiness
“NIS2 hits 30,000+ EU mid-market organizations that were never in scope under NIS1. Most have no firewall change management process documented. The audit-trail requirement under Article 21 is the gap that will catch them — and the one that's solvable in weeks, not years.”
