Immersive Labs (Immersive One) is a cyber workforce readiness platform that delivers hands-on, scenario-based labs for cybersecurity skill development and resilience measurement. The platform provides practice environments spanning offensive security, defensive operations, cloud security, application security (AppSec), SOC analysis, incident response, OT, and DevSecOps. Labs are mapped to industry frameworks including MITRE ATT&CK, OWASP Top 10, NIST Cybersecurity Framework, and DORA compliance. An AI Lab Builder feature enables organizations to create and update custom labs based on current threat intelligence. Scenarios are informed by Container 7 research, which translates current adversary tradecraft and AI attack techniques into training content. Role-based adaptive learning pathways adjust difficulty based on individual performance, targeting roles such as analysts, engineers, AppSec, cloud, and leadership. A gamified format is used to engage participants in realistic threat scenarios. Analytics capabilities track individual metrics (skill level, accuracy, confidence), team dynamics, progress over time, and benchmark results against industry standards. Resilience scoring provides quantifiable metrics for demonstrating readiness to stakeholders, auditors, and regulators. The platform also includes audit-ready reporting and evidence export functionality to support compliance and leadership communication.
