Does GitHub storing code on US servers create UK GDPR issues?

Source code is generally not personal data (unless it contains personal data, which it should not). UK GDPR applies to personal data — code repositories containing customer data would be a UK GDPR concern. For NHS and government projects: ClickMasters uses self-hosted GitHub Actions runners on AWS eu-west-2 so CI/CD compute runs in the UK. Code storage on GitHub.com (US) for non-personal-data code is standard industry practice.

How does CI/CD satisfy Cyber Essentials change management?

Every GitHub Actions CI/CD run generates: a git commit hash (immutable change record), a CI run log (test results, security scan results), and a deployment record (what was deployed, when, by whom). This is the Cyber Essentials change management evidence trail. ClickMasters configures branch protection rules (PRs require passing CI before merge) and deployment approvals (production deployment requires explicit approval), satisfying Cyber Essentials change control requirements.

Direct Answer

GitHub Actions is the right default for most UK software teams: native GitHub integration, excellent marketplace (thousands of pre-built actions), generous free tier, and no infrastructure to manage. GitLab CI is better when you want a complete DevSecOps platform (code repository + CI/CD + container registry + security scanning in one). Jenkins should only be used for legacy pipelines where migration cost outweighs benefit. CI/CD platform choice affects developer productivity, UK Cyber Essentials change management evidence, and the security of your software supply chain. Here is an honest UK comparison.

Factor	GitHub Actions	GitLab CI	Jenkins
Setup complexity	✅ Zero — native GitHub integration	Medium — GitLab setup required	High — server management required
Cyber Essentials evidence	✅ PR + Actions run = audit trail	✅ MR + pipeline = audit trail	Manual — audit trails need configuration
UK data residency	GitHub.com (US) — code only	GitLab.com (US) or self-hosted in EU	Self-hosted anywhere — full control
SAST security scanning	✅ CodeQL (free for public)	✅ GitLab SAST (free tier available)	Via plugins — OWASP ZAP, SonarQube
Secret management	GitHub Secrets + OIDC to AWS	GitLab CI variables + OIDC	HashiCorp Vault + Jenkins credentials
Marketplace	✅ 20,000+ actions	GitLab CI templates	Jenkins plugins (often outdated)
NHS/GovTech supply chain security	SLSA provenance via Actions	GitLab Dependency Scanning	Manual configuration required
Self-hosted runners (UK data)	✅ Available — run in eu-west-2	✅ Available — GitLab Runner	✅ All on-premises — maximum control
ClickMasters default	✅ All new projects	Full DevSecOps platform needed	Legacy only — no new projects
