Give us a brief overview of the path that led to your current role.
I started my career as an IT systems engineer and continuously took on additional challenges. The pivotal time in my career was during law school, while also working full time as an IT and security leader. It was during that time that I elected to focus primarily on cybersecurity and privacy.
What is one of your guiding leadership principles?
Making THE difference, through transparency, commitment, surrounding myself with people smarter than me and asking lots of questions.
What is the greatest challenge CISOs face today, and how are you addressing it?
The biggest challenge is managing cyber risk in an environment of accelerating complexity and accountability, amid an expanding attack surface, AI-driven threats, regulatory pressure, or Board-level accountability. Aligning security with business risk, prioritizing resilience and leveraging AI for defense are few examples of approaches to addressing today's challenges.
What is the key to success for someone just starting out as a CISO?
The key to success is building trust and credibility quickly while aligning cybersecurity with business objectives. This means focusing on clear communication with the board, prioritizing risk-based decision-making over technical minutiae, and fostering a culture of collaboration across the organization.
How do you measure success as a leader?
Success as a security leader means reducing business risk while enabling growth, earning stakeholder trust, and building a resilient security culture that can withstand and adapt to evolving threats. Compliance or tool deployment will not suffice.
