A Security Champion is a member of a development or product team who takes on security advocacy as part of their role, acting as the local point of contact between that team and the central security organization. The position is usually not a dedicated full-time job but an extension of an engineering, quality, or product role, and it is most often formalized through a company's security champions program. The underlying rationale is one of scale: security teams are almost always far smaller than the engineering population they support, so embedding knowledgeable advocates inside each team extends security's reach and brings judgment closer to where code and design decisions are actually made.
Day to day, a Security Champion keeps security visible in the ordinary rhythm of their team's work. They raise security considerations during design discussions and sprint planning, help triage findings from automated scanners so that developers are not overwhelmed by noise, and answer routine questions that would otherwise queue up with the central team. They often shepherd threat modeling sessions for new features, track remediation of known issues, and help their team understand and adopt secure defaults, libraries, and patterns. A champion also relays information in both directions, carrying policies, tooling changes, and threat intelligence from the security organization into the team, and carrying the team's friction points and practical constraints back out. The role is deliberately influence-based rather than authority-based, so persuasion, patience, and credibility with peers matter as much as technical depth.
The background that suits the role is a working developer or engineer who already has the trust of their team and a genuine interest in security, rather than a security specialist parachuted in from outside. Useful skills include a solid grasp of the team's technology stack, familiarity with common weakness classes such as those cataloged by OWASP, comfort reading scanner output and reasoning about risk, and strong communication. Deep offensive expertise is not required; what matters more is the ability to recognize when something warrants specialist attention and to translate security concerns into terms that resonate with fellow engineers. Many organizations support champions with targeted training, a community of practice, recognition, and dedicated time, since a program without real investment tends to fade.
People typically enter the role by volunteering or being nominated within an existing engineering position, then growing through program training and hands-on exposure to real findings and incidents. Over time, a champion deepens their security knowledge and may broaden their influence across several teams or mentor newer champions. The experience is a well-worn on-ramp into dedicated security work, and champions frequently move into specialist roles once they decide to make security their primary focus.
The Security Champion sits alongside several more specialized application security roles and is best understood by contrast with them. Where an Application Security Engineer owns tooling and program-level defense across many teams, a Secure Code Reviewer concentrates on finding flaws in source, a Product Security Engineer owns the security of a specific product line, and a DevSecOps Engineer embeds security controls into pipelines and infrastructure, the champion is defined instead by being a practicing team member who carries security into daily development. Champions are the local, part-time complement that makes these centralized functions effective at scale, and the relationship is symbiotic: the specialists set direction and provide depth, while champions provide reach, context, and sustained presence inside each team.
