BreachX One is a threat intelligence platform focused on zero-day vulnerability detection and defense. The platform monitors adversary activities in dark web forums, Telegram groups, and exploit marketplaces to identify threats 30-90 days before public disclosure. The platform consists of four main suites: Intelligence Suite for adversary web monitoring and dark web tracking; Protection Suite for continuous exposure assessment including IoT/OT security (IndusHawk), third-party risk management, cloud security, and bug bounty programs; Simulation Suite for breach attack simulation, cyber range OT training, red team campaigns, and purple team exercises; and Response Suite for threat hunting, digital forensics and incident response (DFIR), coordinated takedowns, and crisis public relations. The platform combines AI-driven analysis with human analyst verification to detect vulnerabilities before they appear in public databases. It provides real-time security posture scoring with automated actions such as restricting risky vendor access. The simulation capabilities mirror attacker tactics, techniques, and procedures (TTPs) across the MITRE ATT&CK framework to validate security controls and measure response effectiveness. BreachX One targets BFSI (Banking, Financial Services, and Insurance) sectors and organizations requiring proactive defense against nation-state actors and advanced persistent threats.
