Courses That Close the Gap Between Certification and Capability.

You passed the exam but can't build the detection, investigate the incident, or present the architecture. These courses produce the artifacts that prove you can do the work — deployed in your environment, not a sandbox.

Every course produces artifacts you deploy at work.

Detection rules that fire on real attacks, playbooks that contain real incidents, architectures your CISO approves
Built in your own environment — persistent labs that never expire
Verification scripts confirm your work is production-ready before you move on
Written by practicing security engineers · 34 courses · New modules added regularly
From $179/year — every course includes free modules. See pricing →
Security Engineering

Identity, Endpoint & Platform Security

After these courses, your Conditional Access framework is documented and defensible, your endpoints are hardened to a verifiable baseline, and your M365 security stack is configured the way it should have been from day one — not the way the defaults left it.

Detection & Hunting

Detection Engineering, KQL, Threat Hunting & Offensive Analysis

After these courses, threats that used to slip through your SIEM undetected are caught by rules you wrote, tested, and deployed. You produce 71 production KQL rules, execute 10 complete hunt campaigns, understand how attackers plan and execute campaigns, and build a detection-as-code pipeline that keeps your coverage current.
