4 Day, Instructor Led Training (ILT) CAJE

Cellebrite’s Advanced JTAG Extraction (CAJE) training is an expert level four-day certification course lead by Cellebrite Certified Instructors (CCIs). During this course, participants will learn about the JTAG process, electrical theory, methodologies, and purpose as well as understand the equipment and accessories necessary for successful JTAG extractions. Instructors will help attendees to not only develop, but also to hone fundamental soldering skills, gain practical knowledge with hands-on practice as well as share best practices and legal considerations for processing JTAG extractions. Additionally, participants will learn how to fully leverage the Physical Analyzer to decode JTAG extractions properly. As part of their attendance, participants will receive a RIFF 2 JTAG box, a Z3X Pro (Easy JTAG) box, a Molex adapter kit, a class specific toolkit, and a Cellebrite soldering practice board.
