DevOps & CI/CD for UK FinTech Companies — FCA PS21/3 Built In

FCA Operational Resilience (PS21/3)

FCA requires regulated firms to demonstrate the ability to stay within impact tolerances during disruption. DevOps practices directly support this: zero-downtime rolling deployments (no maintenance windows), automated rollback capability (instant revert if a release causes issues), infrastructure as code (Terraform — changes are reviewed and auditable), and automated testing (preventing broken releases from reaching production).

PCI-DSS in CI/CD Pipelines

Payment Card Industry standards require that cardholder data environments are protected. In CI/CD: no card data in test environments (use tokenised test data), secrets management for API keys (AWS Secrets Manager, not hardcoded), automated dependency scanning (Snyk, Dependabot) for PCI-relevant vulnerability detection, and deployment audit trails for PCI DSS Requirement 6 (change management).

Cyber Essentials Patch Management via CI/CD

The Cyber Essentials patch management control requires high-risk vulnerabilities to be patched within 14 days. ClickMasters implements: Dependabot for automated dependency update PRs, SAST scanning (Semgrep, ESLint security rules) in every PR, container image scanning (Trivy) on every Docker build, and rapid deployment pipeline enabling patch deployment within hours of merge.

Audit Logging for FCA Compliance

FCA regulated firms must maintain audit logs of all significant system activities. DevOps practices support this: centralised logging (ELK stack or CloudWatch/Azure Monitor), immutable log storage (logs written to S3/Blob Storage with object lock), automated log retention (7 years for financial records), and SIEM integration for real-time security monitoring.
