Our Arizona range operator is The Arizona Cyber Warfare Range (AZCWR - azcwr.org)
We are working with the Wisconsin Cyber Threat Response Alliance (WICTRA - wictra.org)
Our first range was started in 2012. We began humbly with a donated 42u rack and 10 servers. Our first location was not easily accessible, so in 2014 we looked for and found another location inside a controlled facility in the phoenix-metro area.
That move opened the door to more in-person visits and allowed us to connect with companies, other organizations, and many more volunteers.
