Sounds like a classic “panic‑before‑the‑attack” scenario. Start by hardening the pipeline: add a mandatory code review that actually checks for secrets, run static analysis and dependency scanning on every commit, and make sure your CI uses immutable, sandboxed runners. Pin dependencies, lock out dynamic imports, and enforce TLS everywhere. Keep secrets in a vault, never in the repo, and rotate them on a schedule. Add automated security tests to the nightly build, then do a staged rollout with canary environments that have strict rate‑limiting and logging. When you ship, use immutable containers, signed images, and a blue‑green deployment strategy so you can roll back instantly if something slips. Finally, keep a clean audit trail—log everything, then throw away logs that aren’t useful. That’s the cycle: review, scan, lock, test, deploy, monitor. If you hit a snag, patch it immediately and push the fix to the same pipeline so the same safety net catches future regressions.
