About Choice Guide Lab
Choice Guide Lab is a technical resource built for network security and infrastructure engineers ? people who manage real production environments and do not have time for content that skips the hard parts.
About the Author
Choice Guide Lab is founded and maintained by Jayden Cho, a Senior Network Security Engineer with hands-on experience managing enterprise firewall infrastructure — primarily FortiGate — across OT and IT networks. Jayden holds professional certifications in network security and has spent years building AI-assisted automation tools to make security operations faster and less error-prone.
What We Cover
The guides and tools on this site come from hands-on work across enterprise network environments, cloud platforms, and AI-assisted infrastructure operations.
- Network Security & Infrastructure ? firewall policy management, network segmentation, VPN, zero-trust architecture, NAC, and incident-driven troubleshooting
- Cloud Security ? IAM hardening, CSPM, Kubernetes security, workload identity federation, and CI/CD pipeline security
- AI & Automation for Ops ? practical use of LLMs, MCP servers, agentic workflows, and AI-assisted tooling for real infrastructure and security work
- DevSecOps & Compliance ? automated compliance checking, vulnerability scanning pipelines, policy-as-code, and audit methodology
- Security Tools ? hands-on reviews, tutorials, and open-source tools built and tested in production environments
Our Approach
Every guide is written from the perspective of engineers who have managed production systems ? not from documentation or theory. That means specific version numbers, real before-and-after metrics, and honest accounts of what went wrong along the way.
We do not publish content we have not tested. We do not recommend tools we do not use.
Who This Is For
- Network and security engineers managing enterprise infrastructure
- Cloud and DevSecOps teams working on security automation and compliance
- IT practitioners evaluating AI-assisted tooling for operations and incident response
- Security auditors who need practical, production-tested checklists and frameworks
