DevSecOps-as-a-Service
Secure your pipelines, cloud infrastructure and workloads — delivered by a senior DevSecOps engineer, on a fixed-price sprint or monthly retainer.
Your CI/CD pipelines are an attack surface
Supply chain attacks, hardcoded secrets, compromised runners — the majority of 2024 incidents originated in the pipeline itself.
Secrets, IaC and containers left unsecured
API keys in code, Terraform without scanning, Docker images with critical CVEs — the most exploited vectors in production.
No time for a full DevSecOps hire
A senior DevSecOps engineer costs £60-100k/year and takes 3-6 months to hire. A freelance engagement ships in one week.
I secure your systems as if I were embedded in your team: hardened pipelines, Zero Trust cloud, dynamically managed secrets, scanned containers — shipped to production.
Senior DevSecOps execution. Freelance flexibility. Zero recruitment overhead.
What I deliver
Targeted interventions on the highest-risk attack surfaces in your stack.
Pipeline & CI/CD Security
Full hardening of your GitHub Actions / GitLab CI pipelines — from secrets detection to SLSA artifact signing.
- ·Secrets scanning (gitleaks, truffleHog) + pre-commit hooks
- ·GitHub Actions: least-privilege GITHUB_TOKEN
- ·Supply chain: SBOM, Sigstore/Cosign, SLSA L2-L3
- ·Branch protection, signed commits, CODEOWNERS
Cloud & IaC Security
Zero Trust architecture on AWS, GCP or OVHcloud — IAM least-privilege, WAF, network segmentation and Terraform/Ansible scanning.
- ·IaC scanning: Checkov, tfsec, PR integration
- ·IAM Analyzer, SCPs and least-privilege policies
- ·WAF, rate limiting, OWASP API Top 10
- ·CIS Benchmarks, CSPM (Security Hub, SCC)
Secret Management & Vault
Zero hardcoded secrets in production: HashiCorp Vault, AWS Secrets Manager, External Secrets Operator, SOPS/age.
- ·Vault architecture (AppRole, K8s Auth, HA)
- ·Dynamic secrets and automatic rotation
- ·External Secrets Operator for Kubernetes
- ·Encrypted GitOps: SOPS + age + KMS
Container & Kubernetes Security
Image scanning, runtime hardening, strict Kubernetes RBAC and NetworkPolicies to isolate your workloads.
- ·Image scanning: Trivy, Grype, CI integration
- ·RBAC, Pod Security Standards, NetworkPolicies
- ·Non-root containers, read-only filesystems
- ·Admission controllers (OPA/Gatekeeper, Kyverno)
SAST / DAST & Automation
Automated vulnerability detection in code and at runtime — Semgrep, CodeQL, OWASP ZAP integrated into the pipeline.
- ·SAST: Semgrep, CodeQL, SonarQube in CI
- ·SCA: Dependabot, Snyk, license detection
- ·DAST: OWASP ZAP in staging pipeline
- ·STRIDE threat modeling on architectures
Monitoring & Incident Response
Anomaly detection, SIEM alerting, incident response runbooks and cloud forensics (CloudTrail, GCP Audit Logs).
- ·SIEM integration, alerting on critical events
- ·CloudTrail / GCP Audit Logs forensics
- ·Documented incident response runbooks
- ·Post-incident review and corrective hardening

Need a CISO on top of the engineering?
DevSecOps covers technical implementation. If you also need governance, NIS2/ISO 27001 compliance and board reporting, my CISO-as-a-Service offering picks up where this leaves off.
