Totem helps security trainers extend the learning experience from a few days of face-to-face, offline training into a continuous and on-going, interactive learning experience. For example, trainers can curate courses on basic tools and concepts that learners take in preparation of a face-to-face, classroom training. Totem can also be used after a face-to-face training has concluded, so learners can continue to learn advanced concepts and stay in touch with trainers using secure communication methods provided via the platform.
