CI/CD Pipeline Security Review
Harden your software supply chain. Security audit of CI/CD pipeline configurations, secret management, RBAC, dependency integrity, build agents, and artifact signing — SLSA framework aligned.
Configuration · Secrets · Supply Chain
Pipeline configuration review, secret management assessment, and software supply chain security — covering GitHub Actions, GitLab CI, Jenkins, and Azure DevOps.
Pipeline Configuration Security Review
Reviewing pipeline configuration files (YAML workflows, Jenkinsfiles, GitLab CI configs, Azure Pipelines YAML) for insecure settings — overly permissive pipeline triggers, unprotected environment variables, unsafe script injections, excessive job permissions, and unprotected branch rules.
- GitHub Actions workflow YAML security review
- GitLab CI/CD configuration security assessment
- Jenkins Declarative and Scripted pipeline audit
- Azure Pipelines YAML and classic pipeline review
Secret Management & Credential Security
Reviewing how secrets are stored, accessed, and managed across the CI/CD environment — identifying hardcoded credentials in pipeline configs, repository history scanning for exposed secrets, vault integration review, and secret rotation lifecycle assessment.
- Hardcoded secret detection (pipeline configs, environment variables)
- Git repository history scanning (GitLeaks, truffleHog)
- Secrets manager integration review (Vault, AWS Secrets Manager, Azure Key Vault)
- Secret rotation and expiry policy assessment
Third-Party Dependency & Supply Chain Security
Assessing the security of third-party dependencies and actions used in the pipeline — detecting dependency confusion attack vectors, reviewing third-party GitHub Actions for supply chain risk, verifying dependency integrity via lock files and package signing, and assessing artifact protection controls.
- Dependency confusion attack surface mapping
- Third-party GitHub Action provenance review
- Build artifact signing and integrity verification
- Software Bill of Materials (SBOM) coverage assessment
Your Build Pipeline Is a Privileged Backdoor Into Production
The CI/CD pipeline has access to production secrets, deployment credentials, cloud provider accounts, and every environment the software runs in. Compromise the pipeline, and an attacker doesn't need to exploit your application — they can inject malicious code directly into the build, push it to production, and cover their tracks in the deployment logs.
Supply chain attacks via CI/CD pipelines are among the most high-impact breach vectors in modern enterprise security — and the security of most pipelines still reflects the assumption that they're a trusted internal tool, not a primary attack target.
Pipeline Injection
Untrusted PR content mapped into pipeline script execution allows external contributors to run arbitrary code on build infrastructure.
Exposed Secrets
Hardcoded secrets in Git history and pipeline configs are found within 4 minutes of repository exposure by automated scanners.
Dependency Confusion
Private package name conflicts with public registry allow attackers to supply malicious build dependencies at scale.
Build Agent Compromise
Shared, persistent build agents — common in Jenkins — accumulate state and credentials from multiple builds, creating lateral movement paths.
5-Phase CI/CD Security Review
From pipeline architecture and access control assessment through configuration analysis, secret scanning, supply chain review, and SLSA maturity reporting.
Pipeline Architecture & Access Control Review
Mapping the complete CI/CD pipeline architecture — pipeline platforms, build agents/runners, deployment targets, and access control configuration. Reviewing user permissions, service account permissions, branch protection rules, and environment protection rules across all pipeline platforms in scope.
Pipeline Configuration Security Analysis
Static analysis of all pipeline configuration files — GitHub Actions workflow YAMLs, Jenkinsfiles, GitLab CI configs, and Azure Pipelines templates — checking for injection vulnerabilities, insecure triggers, overly permissive job permissions, unprotected secrets, and unsafe third-party action usage.
Secret & Credential Security Assessment
Comprehensive secret security review — scanning pipeline configs and repository history for hardcoded credentials, reviewing secrets manager integration and access patterns, assessing service connection and service account scoping (least privilege), and evaluating secret rotation practices.
Supply Chain & Dependency Integrity Review
Assessing the security of the software supply chain — dependency confusion attack vectors (private package namespace collision), third-party GitHub Action provenance (version pinning to digest vs. tag), SCA tool coverage, build artifact signing and integrity verification, and SBOM generation coverage.
Build Agent Security & Reporting
Assessing the security posture of build agents and runners — isolation configuration (shared vs. ephemeral runners), patch and OS currency, network access controls, and artifact storage permissions. Producing a prioritized finding report with SLSA framework gap assessment and remediation roadmap.
Complete CI/CD Security Coverage
From pipeline config review and secret detection through access control, dependency integrity, build agent security, and SLSA framework alignment.
Pipeline Configuration Review
Security review of GitHub Actions YAMLs, Jenkinsfiles, GitLab CI configs, and Azure Pipelines templates — identifying injection vulnerabilities, insecure triggers, unprotected environment variables, and overly permissive job permissions.
Secret Detection & Management
Scanning pipeline configs and Git history for hardcoded API keys, passwords, certificates, and tokens — plus review of secrets manager integration, access policies, and secret rotation lifecycle.
Access Control (RBAC) Review
Validating least-privilege access across the CI/CD platform — pipeline user permissions, service account scoping, branch protection rules, environment protection rules, and deployment approval gates.
Dependency Integrity
Dependency confusion attack surface assessment, third-party GitHub Action provenance review, dependency lock file validation, SCA tool coverage gaps, and package registry configuration security.
Build Agent Security
Security assessment of build agents/runners — isolation configuration (shared vs. ephemeral vs. self-hosted), operating system patch currency, network access controls, and artifact storage permissions.
Artifact Protection & SLSA
Build artifact signing and integrity verification (Sigstore, Cosign), artifact registry access control review, provenance attestation coverage, and SLSA framework gap assessment for supply chain security maturity.
Pipeline Security That Covers the Real Attack Vectors
Supply chain attacks are now the primary delivery mechanism for nation-state and advanced persistent threat actors. We review CI/CD pipelines with the attack patterns that sophisticated threat actors actually use — not a generic security checklist.
Supply Chain Attack Focus
We design CI/CD security reviews specifically around the attack patterns used in real-world supply chain attacks — pipeline injection, compromised third-party actions, dependency confusion, and build artifact tampering — not generic security checklists.
All Major Pipeline Platforms
Deep review capability across GitHub Actions, GitLab CI/CD, Jenkins (Declarative and Scripted), and Azure DevOps Pipelines — with platform-specific findings and remediation guidance for each.
SLSA Framework Alignment
We map all CI/CD findings to the SLSA (Supply-chain Levels for Software Artifacts) framework — giving you a structured maturity model for your pipeline security program with a clear roadmap to SLSA Level 2 and Level 3.
History & Runtime Coverage
CI/CD security reviews must cover Git history (for exposed secrets already committed) and runtime pipeline behavior (for injection and access control weaknesses) — not just static configuration review. We cover all three layers.
