The Four Cs: Why a Schoolteacher Makes a Great CISO
Thu Jan 29 2026
In this episode of The New CISO, host Steve Moore speaks with Manuel "Manu" Ressel, CISO at SAUTER Group, about his unconventional journey from classroom teacher to cybersecurity leader—and why the "Four Cs" of modern education provide a powerful framework for building effective security programs. Drawing from years as both a teacher and school principal in Germany, Manu introduces Critical Thinking, Communication, Collaboration, and Creativity as essential leadership skills that fundamentally challenge how the industry approaches awareness training and incident response.
After growing frustrated with Germany's outdated education system that prioritized memorization over critical thinking, Manu left his position as principal and reinvented himself as a digital transformation consultant. Working with schools and mid-sized companies to adopt cloud technologies, he eventually landed the CISO role at SAUTER, an international building automation company with 4,000 employees across multiple countries.
The conversation tackles security's most persistent failure: awareness training that doesn't work. Manu reveals that 37% of security incidents in Germany could be prevented if users made better decisions, yet most organizations rely on boring click-through programs. He advocates for scenario-based, role-specific training—an approach now mandated by Europe's NIS 2 regulation—that treats people as the biggest opportunity in cybersecurity rather than the weakest link.
One of the episode's most practical frameworks is Manu's Observation-Description-Interpretation method for analyzing security incidents. He explains how humans naturally jump from observation directly to interpretation, skipping the crucial middle step of accurately describing what actually happened. This leads to finger-pointing, misdiagnosis, and hasty decisions. By training security analysts to pause and describe incidents factually first, teams make better decisions and build trust with the business.
Manu challenges the punitive approach many organizations take toward security failures, particularly companies that fire employees for repeatedly clicking phishing simulations. He champions building positive fault cultures where employees feel safe reporting mistakes. His three crisis questions—Is anyone dying? Major financial impact? Will someone be hurt?—provide a simple framework for staying calm and deciding when immediate action is necessary versus taking time to think strategically.
Key Topics Discussed:
Why the "Four Cs" (Critical Thinking, Communication, Collaboration, Creativity) define effective security leadershipThe Observation-Description-Interpretation framework for incident analysis without biasTransforming ineffective awareness training into engaging, scenario-based programsBuilding positive security cultures where employees report issues without fearNIS 2's mandate for role-specific cybersecurity training across organizational levelsWhy Germany and European mid-market companies lag in cloud adoptionThree critical crisis questions: Is anyone dying? Financial impact? Risk of harm?Why punitive phishing training destroys trust and cultural engagementApplying teacher skills to security leadership and de-escalation...
