On paper, risk management is a clean matrix of probabilities and impacts. In reality, it is a series of impossible decisions made under maximum uncertainty. Carsten Marmulla has spent decades navigating this reality, combining academic rigor with pragmatism learned from the "school of hard knocks".

As a Senior Trusted Advisor and the founder of the cybersecurity consulting boutique carmasec, he translates cyber resilience from a technical challenge into an executive survival strategy.

Through his roles as a vCISO, IT security manager, and strategic advisor for large enterprises, Carsten has guided numerous organizations through complex digital transformations and risk mitigation programs.

He challenges the dangerous illusion that green dashboards and standard certifications equal true security. Instead, he uses his trademark "plain talk" (Klartext) to bridge the communication gap between technical teams and the C-suite.

Beyond his consulting work, Carsten actively mentors cybersecurity startups, shaping the future of the industry.

On stage, he combines the hard-won insights of an entrepreneur with the strategic depth of a management consultant, giving decision-makers the tools they need to build truly resilient organizations.
