1-on-1 coaching and consulting from a federal SOC engineer actively hardening government infrastructure — CIS benchmarks, Tenable VM, Ansible automation, and Red Hat certs done right.
Targeted coaching built around your weak spots. Real lab scenarios, timed drills, and exam strategy from an active RHCE who has trained hundreds of students to a 90% first-attempt pass rate.
CIS benchmark implementation, STIG compliance, Ansible playbook automation, and Tenable VM vulnerability ops — real federal-grade execution, not textbook theory.
Breaking into federal cybersecurity, cert roadmap planning, clearance navigation, and reading government job postings like an insider who has been inside.
Tenable.sc / VM workflows, POA&M reporting, CISA KEV remediation, and compliance scanning from someone running these tools daily in a live federal SOC environment.
Scripting built for sysadmins — API integrations, Excel/CSV report generation, Ansible extensions, and cron pipelines. No abstract theory, just real work scripts.
6-week structured cohorts for RHCSA prep or federal Linux fundamentals. Weekly live sessions, hands-on labs, and a private Slack group for peer accountability.
I'm Lionel Agishi — a federal SOC engineer currently hardening government infrastructure at FERC. Every technique I teach, I use in production daily. No courses built from documentation. No theory without application.
With 10+ years across RHEL 7/8/9, VMware, Azure, and classified environments, I've administered 1,500+ servers, built CIS hardening pipelines with Ansible, and led vulnerability operations using Tenable across federal compliance frameworks including FISMA and CISA KEV.
Previously I trained hundreds of students at YellowTail Tech, achieving a 90% RHCSA pass rate. Now I take on private clients who want the real thing.

$75/session"Lionel doesn't teach you to memorize — he teaches you to think like an engineer. Passed RHCSA on my first attempt after just three sessions."
"The hardening session was eye-opening. He walked me through exactly how CIS benchmarks translate to real Ansible plays. Pure hands-on, zero fluff."
"One hour with Lionel gave me a six-month roadmap I actually followed. Got my first federal offer five months later. Worth every dollar."
