Dan Sorensen is a fractional vCISO and AI governance advisor, and the founder of Nexus Security Advisors, serving small and mid-sized businesses, aerospace suppliers and critical infrastructure operators. A 22-year U.S. Air Force and Air National Guard cyber veteran, he translates cyber threats into boardroom decisions, building security programs against NIST RMF, NIST AI RMF, ISO 27001, ISO/IEC 42001, CMMC, HIPAA and the EU AI Act. He contributes to the OWASP AI Exchange, writes for Forbes Technology Council and is a PhD candidate in Cybersecurity Leadership at Capitol Technology University.

​

Dan brings more than technical depth. He understands the engineering, and he equally understands program management, leadership and the "whole person" concept: people, process, mission and business all have to work together for security to stick. He leads as a servant leader, putting the needs of his teams and clients first, clearing obstacles out of their way and helping others grow into leaders themselves.

​

His work ethic comes from family. Early on, he learned that hard work matters and that a job worth doing is worth doing well; quality work, done right the first time, is a point of pride. That lesson shows up in every program he builds and every client he serves.

​

At heart, Dan is a volunteer and a humanitarian. He gives his time to the OWASP AI Exchange to help shape open AI security guidance for the global community, and he mentors veterans and newcomers starting careers in cybersecurity. Kind, approachable and community-minded, he believes in giving back wherever he can. He speaks English, Spanish, Portuguese and Italian, which helps him connect with people and organizations across cultures. Outside of security, he holds International Sports Sciences Association (ISSA) certifications as a Certified Personal Trainer, Nutrition Coach, Bodybuilding Specialist and Certified Pilates Instructor, earning ISSA's Elite Trainer designation, and he is a PADI Advanced Open Water Diver.
