Establish DevSecOps metrics and reporting cadence
Implementation Effort: Medium – Selecting metrics, wiring data from GitHub Advanced Security, Azure DevOps, and Defender for Cloud, and standing up a reporting cadence requires cross-team coordination. User Impact: Low – Building and delivering security metrics reports is a security and engineering-leadership activity; end users are not affected. Lifecycle Stage: Govern
Overview
Establish a DevSecOps metrics and reporting cadence so your organization can measure scanning coverage, remediation speed, backlog health, and overall program effectiveness across repositories and pipelines.
Deploying security scanning tools and configuring pipeline protections is necessary but insufficient. Without defined metrics and a regular reporting cadence, security teams cannot distinguish between a program that is effectively reducing risk and one that is generating alerts no one acts on. Mean time to remediate may be growing. Scanning coverage may have silently dropped as new repositories were onboarded without CodeQL configuration. Alert backlogs may be accumulating faster than teams can triage them. None of this is visible without deliberate measurement.
DevSecOps metrics translate security tool output into actionable indicators of program health. Key performance indicators typically include mean time to remediate critical and high-severity findings, the percentage of repositories and pipelines with active security scanning, the age and volume of the open alert backlog, the ratio of findings resolved versus suppressed, secret exposure incident frequency, and dependency vulnerability remediation velocity. These metrics should be sourced from GitHub Advanced Security, Azure DevOps, and Microsoft Defender for Cloud, and reported to both engineering leadership and security leadership on a regular cadence — weekly for operational teams and monthly or quarterly for executive stakeholders. Trends matter more than point-in-time snapshots, so reporting should emphasize direction of change over absolute numbers.
Organizations that operate DevSecOps programs without metrics and reporting cannot demonstrate improvement, justify investment, or identify which teams or repositories need additional support. It also weakens the Assume breach principle, because without visibility into remediation velocity and coverage gaps, the organization cannot confirm it is reducing its exploitable attack surface over time.
Metrics are only useful if they drive action. Use the KPIs to run targeted remediation campaigns: time-boxed, prioritized drives to eliminate a specific class of risk across the estate — for example, resolving all critical secret-scanning alerts, closing exposed-and-exploitable findings surfaced by attack path analysis, or bringing every production-facing repository above a coverage threshold. Prioritize campaigns by exploitability and asset criticality (using the asset registry from the prioritized onboarding model and the unified view from the centralized DevSecOps security dashboards), assign findings to owning teams with clear deadlines, and track burn-down as a first-class metric so leadership can see a measurable reduction in risk rather than a perpetually growing backlog.
