Guido Grillenmeier stories

Guido Grillenmeier explores how cyber security is evolving from a focus on perimeter defence to a broader, more resilient approach built around identity and operational continuity. His writing looks beyond traditional tools and tactics to examine how organisations can prepare for, withstand and recover from inevitable cyber incidents.

Through his stories, readers gain insight into why logins have become as critical as physical locks, how identity security underpins modern resilience strategies, and what practical steps can shift security thinking from pure prevention to sustained operation under attack. If you want to understand cyber resilience in real-world, operational terms, Guido’s work offers clear guidance and thought-provoking perspectives.
