Why teams enroll
Built for reviewers who own the evidence file
Walkthrough scripts that hold
Practice facilitator notes that keep product, risk, and engineering aligned when an auditor asks “show me the override path.”
Korea-aware delivery
Cohorts run from our Incheon office hours with materials that acknowledge local licensing language while staying useful for cross-border teams.
