The role of security practices is increasingly recognized in fast-paced software development paradigms in contributing to overall software security. Security champions have emerged as a promising role in addressing the dearth of explicit security activities within software teams. Despite the growing awareness of general security practices, there remains limited knowledge regarding security champions, including their establishment, effectiveness, challenges, and best practices.

This paper aims to bridge this gap by presenting insights from a survey of 73 security champions and 11 interviews conducted within a large Norwegian software house. Through this study, we explore the diverse activities undertaken by security champions, highlighting notable differences in motivations and task descriptions between voluntary and assigned champions.

We also reported challenges with onboarding, communication, and training security champions and how they can be better supported in the organization. Our insight can be relevant for similar software houses in establishing, implementing, and improving their strategic security programs.
