Implement stealth-oriented authentication and password testing methodologies reflecting modern attacker tradecraft.
Simulate access abuse and data exfiltration across critical SaaS-based knowledge and information management ecosystems.
Ensure NodeZero capabilities are realistic, production-safe, and aligned with modern attacker tradecraft.
Partner with Product and Design to translate field insights into prioritized roadmap input and productized capabilities.
Create tight feedback loops between real-world attack findings and platform evolution.
Help define next-generation attack surfaces across cloud and AI systems.
Own the UI/UX and product design for the external attack surface and perimeter breach scenarios, including simplifying the configuration of attack operations and developing visualizations that translate complex attack paths into clear, actionable storytelling regarding customer risk, exploitability, and findings.
