CJDE — Security Blue Team Certified Junior Detection Engineer
Security Blue Team's detection engineering certification launched September 2025, targeting junior analysts and SOC practitioners with 1-3 years of IT or security experience. Addresses a recognized gap — most detection engineering certifications either target experienced engineers or lack a hands-on practical component. CJDE covers attacker behavior translation into actionable detections, YARA and Sigma rule creation and tuning, Zeek network analysis, detection rule investigation, threat intelligence integration, and AI-assisted detection. 120+ lab hours, 400+ lessons, 40-60 hours to complete, rounded off with a practical hands-on exam. Priced at £399 (~$495) with an introductory launch offer of £299 — an accessible entry into detection engineering credentials. Lifetime validity. At this price and level, CJDE is positioned between BTL1's SOC analyst scope and GCDA's senior detection engineering content.
