RansomLeak Security Training logo

RansomLeak Security Training

freemium

RansomLeak is security awareness training that replaces passive video courses with interactive 3D cybersecurity simulations. Employees don't watch someone explain what a phishing email looks like. They receive one in a simulated inbox and decide what to do with it. They pick up a call from someone impersonating IT support. They find a USB drive near the office door. Every simulation branches based on their decisions and shows them what an attacker would have done next. Each scenario is built on documented attack patterns from real corporate breaches. The format works because active decision-making under pressure produces stronger recall than passive content. When someone gets fooled inside a simulation and watches the damage unfold, they remember it. Training covers phishing, spear-phishing, business email compromise, social engineering across phone, chat, and in-person channels, data handling, password security, physical security, and incident reporting. Multiple difficulty levels per topic. Gamification with points, badges, and leaderboards keeps completion rates high across large workforces. Security teams get analytics showing where knowledge gaps exist across the organization. Deploys as SCORM packages (1.2 and 2004) for Cornerstone, Workday, SAP SuccessFactors, Docebo, Moodle, Canvas, Blackboard, and other LMS platforms. Or as a standalone cloud LMS with user management, real-time analytics, campaign scheduling, SSO/MFA, and custom branding. Built by the Kontra Application Security Training team for mid-market and enterprise organizations in finance, healthcare, technology, and government.
