The Collegiate Cyber Defense Competition (CCDC) is the premier collegiate cybersecurity competition in the United States. Over 100 teams across different regionals and qualifiers compete every year. It is endorsed by Congress and sponsored by top defense companies, with winners receiving special attention as to recruitment. The scenario is that each college team, the Blue Team, inherits an identical corporate network and has to secure it against a live (not simulated!) team of penetration testers, the Red Team, otherwise known as “the hackers”, all while we are handed business tasks by the corporation who owns the network. It’s the best applied cybersecurity experience you can get in college.

Collegiate Penetration Testing Competition (CPTC) is a newer competition hosted out of Rochester Institute of Technology, which focuses on penetration testing AKA red teaming. We have a corporate network to attack and get as much access as possible within an allotted time. Recruitment and meetings will start in the Spring.


NCL is a national CTF hosted by Cyber Skyline and the National Cyber League Inc. non profit. It is a Jeopardy style capture the flag competition, meaning you get small cybersecurity challenges and have 72 hours to complete them. One you complete one, you get a small piece of text called a “flag”, indicating you got the required unauthorized access or solved the problem
