About the challenges

Hacktivate has 240 graded missions across the Americas, Europe, Asia, and more, all solved using real-world skills.

The app is aimed at two main types of user:

  • Hobbyists, developers, and parents who want to introduce their kids to computers in an engaging way.
  • Students aged 13-21 who are studying IT or computer science at school.

Hacktivate uses the same real-world cybersecurity techniques that white-hat hackers rely on – you'll meet steganography, digital forensics, SQL injection, binary, hex, hashing, encryption, and more.

What people say…

We gave an early version of Hacktivate to high-school teachers. Here's what they had to say…

"Hacktivate is an extremely easy way to supplement the core Computer Science curriculum with exciting and challenging team-based challenges that get students learning and applying real-world cyber security skills. We use it each year to inspire our GCSE students to study the subject at A Level and beyond and each year it goes down like a storm."

David Cornell, Eton College

"Using Hacktivate with my sixth form students was a fantastic success that the students really enjoyed - the class was buzzing. It also covered content from the A-level curriculum such as encryption, hashing, SQL, the Internet, ASCII, HTML/CSS/JS and network security.

Jake Gordon, Cambridge Maths School

"Hacktivate has been an excellent resource in my lessons. My students enjoyed the challenges, and don't want to move on to anything else. Hacktivate show students a world within cyber that they had only been able to talk about in the past."

Ian Jones, St John's College, Cardiff

"Hacktivate is an engaging resource for delivering a range of cybersecurity knowledge and skills. The challenges allow for progression and help develop the critical thinking and research skills required for any going on to take part in the CyberFirst Girls Competition."

James Watts, Oxford High School

"Hacktivate is an impressive resource for educating students in cybersecurity with an engaging hands-on challenge-based approach. We are looking to make good use of it next year with a new cybersecurity lunchtime club to inspire and extend students who are interested in this area."

Paul Baker, The Perse School

"All learners have raised their awareness through the different cybersecurity topics that are challenged within Hacktivate."

Larissa Thomas-Davies, Abertillery Learning Community

"Hacktivate opened students' eyes to various elements of cybersecurity in a very hands-on way. It has developed their problem-solving skills, and they also have a better understanding of the many ways a malicious actor may wish to access or break a system."

Carlo Acosta, King's College School, The Bahamas

"The challenges are clever and fun, and lead students to ask to learn more about networking – it's an outstanding resource that creates the conditions for learning that so many students crave. Students were buzzing with collaborative energy as they strived to top the leaderboards!"

Russell Gordon, Lakefield College School, Canada
