Everyone immediately shouts "GitLab!" or "GitHub Actions!" as if they're handing out candy. Let's be real: the real challenge isn't the pipeline YAML. It's the compliance paper trail that makes or breaks you in an actual audit.
We migrated off a heavily customized Jenkins farm (a compliance nightmare masquerading as a "flexible solution") last year. The primary driver wasn't feature parity; it was the inability to produce an immutable, cryptographically sound audit log for every pipeline run, secret access, and infrastructure mutation. Jenkins logs were… malleable.
So the question isn't just "what CI/CD works." It's what platform can actually deliver:
- Immutable, system-generated logs for every action, tied to a specific service account or human identity (no shared creds).
- Secret management that doesn't just "rotate" but logs every access with a justification context (e.g., "secret X was accessed by deployment job Y for environment prod").
- Integration with our existing SIEM without a dozen fragile parsers.
- A clear, unbroken chain from commit hash to built artifact to deployment, with evidence.
We evaluated the usual suspects. Many fell flat on the "immutable" part. Others had laughable secret audit trails ("service_account_1 accessed vault_key" tells you nothing). The migration pain wasn't in translating steps; it was in rebuilding every process to be fully declarative and credential-less, using workload identity everywhere.
Anyone else been through this gauntlet? Not looking for vendor slides, but actual experiences on what held up under a real GDPR or SOX audit after the switch. How did you handle the translation of legacy "script approvals" that auditors loved to hate?
