Our Vision

Who We Are

"It is impossible for a man to learn what he thinks he already knows."

Purple Hackademy is an online training platform for those who want to become cybersecurity professionals. 

Founded in 2022 by Julien Provenzano, a cybersecurity specialist, who is also an influencer on LinkedIn with a community of 22,000 cybersecurity professionals and learners. For years he has been sharing free recourses with his followers and communicating with a cyber community. That helped him to understand main problems that people have when they decide to become a cybersecurity professional or when they are trying to upskill their knowledge. 

Julien has been getting dozens of messages from learners asking to recommend them a good cybersecurity learning platform, that would give efficient knowledge, needed skills and an affordable price. That motivated him to make a platform that was needed by so many people, where users can get both theoretical and practical knowledge, skills based on real job tasks that are required in companies today and support during the learning process.
