The document discusses the Arizona Cyber Warfare Range (AZCWR), a privately owned cybersecurity training facility. It describes AZCWR as offering a novel approach of allowing trainees to conduct offensive "live hacking" activities over public networks in a controlled environment. This hands-on experience has helped many trainees transition into cybersecurity careers. The AZCWR has grown rapidly since starting in 2014 and now includes a larger dedicated facility. It emphasizes an open, flexible model with mentoring to help address the shortage of cybersecurity professionals across many skill levels.
