Hack The Box Cyber Readiness Platform is an enterprise-oriented platform designed to validate and measure the operational readiness of security teams through hands-on, scenario-based exercises. The platform enables organizations to run threat emulation exercises built from current CVEs and MITRE ATT&CK-mapped tactics, allowing security teams to practice detection, containment, and eradication in a safe, production-like environment. New labs are released weekly to keep pace with emerging vulnerabilities and adversary behaviors. Purple-team ranges allow both offensive and defensive teams to operate within the same session, covering endpoints, identity, and cloud environments. Exercises include lateral movement scenarios and team scoring to identify coordination gaps. Readiness analytics are presented through dashboards that provide MITRE ATT&CK-mapped heatmaps, role-level and tactic-level strength and gap reporting, readiness indices, and trend tracking over time. Results can be exported for audits and post-mortems, and board-ready summaries are available to tie exercise outcomes to organizational risk. The platform supports centralized administration of users, roles, and access. It is used by enterprises, governments, and universities, with over 1,000 organizations listed as customers. Notable customers include Siemens, Deloitte, Toyota, and Google.
