All-Army CyberStakes was organized and hosted by the Army Cyber Institute (ACI).
The ACI ran acictf.com as a pilot program to investigate the use of CTF competitions for training and assessment. They also make this resource available to the broader DoD cyber community to foster the development of technical expertise.
If you are interested in the ACI, or CTFs please email us at email@example.com. We would love to hear from you.
