• Deep analytical skills and problem-solving: A pentest is like a puzzle. You need to analyze a system, identify potential weaknesses, and find attack paths that others might not have considered.
• Clear and impactful communication – You know that a great security report isn’t just about listing vulnerabilities; it’s about telling a story that makes sense to non-technical stakeholders. You translate complex findings into clear, actionable insights.
