Who we are
k>fivefour is the training solution of choice for hands-on cyber operations learning.
Our Mission
k>fivefour’s mission is to empower cybersecurity professionals through superior, hands-on cyber operations training. We believe that cybersecurity is an applied, skills-driven domain, whose practitioners must be able to demonstrate their abilities through hands-on training and certification. This approach ensures those who are certified Red Team operators have demonstrated the ability and aptitude to conduct cyber operations. In short, they can ‘walk the walk’. k>fivefour students are taught by experts with decades of combined experience in real-world cyber operations and a true passion for their tradecraft. This ensures our students learn the latest techniques, and that our training is current and relevant to today’s threats.
