Accomplished software engineer turned information security leader welcoming the new age of security: people-focused programs that properly incentivize taking personal ownership and responsibility for good security habits.

I motivate and align leadership on security strategy and build support in designing effective behavior-oriented information security programs that balance technical security risk with business objectives.

Are you looking for a great place to meet with fellow practitioners and supporters of software security? Haven't been able to find an open discussion format that's not driven by a vendor? Look no further! Join our "Let's Talk Software Security" group here:

With business needs at the forefront, as they should be, most organizations struggle with building security best practices into daily habits. It’s challenging because change is hard. Culture shift is hard. My approach focuses on communicating the importance of security, instilling a sense of urgency, and motivating the organization to shift their mindset toward “Security by Design” best practices, quality focus, and technical responsibility.
