The asymmetric and evolving nature of cyber security means that operators must be lifelong learners. Where seconds matter in an incident, success means expecting that we fall to the levels of our systems and training. Experiential training, or learning in real-world environments and simulations, becomes critical to operational success. Our training solutions makes experiential training possible with realistic network topologies, in a browser-based environment that removes the associated maintenance and overhead of device labs or the expense of cyber ranges. Built with cutting edge technologies, our solution is scalable to any number of learners, and suitable for training in-house teams or for external educators.
