CloudCTF Overview

This KB article provides a general introduction and overview of the Virginia Cyber Range capture the flag platform, known as CloudCTF.

The CloudCTF start page contains the title for CloudCTF, the current date and time, a start button for starting or joining the competition, and the remaining time until the CTF concludes.

What is CloudCTF?

CloudCTF is a fully featured Virginia Cyber Range capture the flag platform that can be deployed in a matter of seconds with a click of a button. It was designed for simplicity and runs in a safe and secure environment in the cloud. It can be provisioned from the Exercise Area of the Virginia Cyber Range for CTF competitions, labs, student practice, and more.

CloudCTF Features

CloudCTF Roles

CloudCTF has two levels of user roles: Admins and Players.

  • CTF Admin (Instructors/TA’s) – Virginia Cyber Range Instructors and TA’s are referred to as Admins in CloudCTF. Players should refer to their CTF Admin as the point-of-contact for questions regarding challenges, scoring, and team management.

  • CTF Player (Students/Guests) – Virginia Cyber Range Students and Guests are referred to as Players in CloudCTF and solve challenges from a variety of categories selected by CTF Admins that enhance the cybersecurity education experience. Players will be able to view and solve challenges, view team statistics, and view the progress and placement of all teams participating in the CTF. If you are a student or guest, please check out our Getting Started in CloudCTF KB article for CTF Players.


Challenges may come from an extensive CloudCTF challenge library or may be custom created by your admin. For help solving challenges, please reach out to your CTF admin, as the Virginia Cyber Range does not assist players in solving challenges.

Players can get started by learning How To Solve A Challenge in CloudCTF.

Team Management

In CloudCTF, all players are on a team even if they are playing by themselves. Permissions of players on teams are controlled by the CTF settings set by the Admin and your role within the team. For detailed instructions related to Team Management, team leaders should review our Team Management article for CTF Players.

Public and Private CTF Competitions

CloudCTF allows for both public and private CTF competitions. Public CTF competitions enable users from outside the Virginia Cyber Range to participate in a CTF, and can be created by enabling public registration in the Admin settings of a CloudCTF environment. Private CTF competitions are the default in CloudCTF and are available only to users enrolled in a Virginia Cyber Range course.

Players can learn more about joining a public or private CTF competition by viewing the Getting Started in CloudCTF KB article for CTF Players.
