Deploy security champion program across development teams
Implementation Effort: Medium – Recruiting champions on each team, defining their responsibilities, and supporting them with training and resources requires sustained cross-team coordination. User Impact: Medium – Selected developers on each team take on champion duties alongside their normal work, so a subset of engineers is affected. Lifecycle Stage: Govern
Overview
Deploy a security champion program across development teams so each team has local security expertise for alert triage, secure design review, and day-to-day guidance.
Centralized security teams cannot scale to review every pull request, triage every code scanning alert, or guide every developer through secure coding practices across a large engineering organization. When security expertise is concentrated in a single team, developers experience security as an external gate that slows delivery, and the security team becomes a bottleneck that cannot keep pace with the volume of code changes. Findings go unreviewed, remediation guidance arrives too late to be useful, and developers lack the context to make secure design decisions in the moment they are writing code.
A security champion program embeds security-focused developers within each engineering team. These individuals remain active contributors to their product while taking on additional responsibility as the first point of contact for security questions, alert triage, and secure design review within their team.
Security champions should receive dedicated training on topics such as threat modeling, secure coding patterns, and the organization's security tooling stack, including GitHub Advanced Security, CodeQL, Dependabot, and Microsoft Defender for Cloud. They should also participate in a cross-team community of practice where they share knowledge, escalate complex issues to the central security team, and bring security context back to their peers. Microsoft's Security Development Lifecycle emphasizes security training for all developers, and the champion model extends that investment by creating local multipliers who translate security policy into practical engineering guidance.
Without security champions, the gap between security policy and engineering practice widens as the organization grows. Developers make insecure design decisions not out of negligence but because they lack accessible expertise at the moment of decision. It also weakens the Assume breach principle, because the organization's ability to respond quickly to vulnerability disclosures and security incidents depends on having informed responders distributed across every team, not concentrated in a single group.
