About David Hazar

David Hazar is a Certified Instructor at the SANS Institute and Founder and Security Consultant at HazarDSec LLC. He works with organizations to improve and mature their security programs, focusing on the practical implementation, automation, and orchestration of existing technologies. As a co-author and instructor for SEC549: Cloud Security Architecture and SEC540: Cloud Native Security and DevSecOps Automation, he brings hands-on operational experience into the classroom.

David’s career trajectory is grounded in technical breadth: he began in municipal systems administration where he handled telephony, databases, domains and networks before moved into application security and vulnerability management. He previously served time with a top-tier security consulting firm, conducting enterprise assessments across startups to large enterprises, and helping embed DevOps and cloud-centric controls into development lifecycles. Those hands-on, messy real-world engagements directly shaped the labs and scenarios in the course, enabling students to simulate root-cause analysis, backlog reduction, and cloud-native architecture remediation in the labs.
