Hi! I'm Sarai Rosenberg.

I'm an infrastructure security leader and mathematician.

About Me

As a manager of infrastructure security teams, I've grown teams into organizations by creating new team functions and capabilities to meet anticipated business needs. I scaled security operations to shift teams from reactive towards proactive investment modes, without getting stuck in firefighting.


I excel at hiring world-class talent, building partnerships, conflict resolution, and influencing systemic change to build security culture and inclusion. I have experience with bare metal infrastructure security, cloud security, key management, incident response, and broad cross-functional collaboration.


I seek to grow the people around me, and I invest in iterative improvement (e.g., managing tech debt and reducing false positives for on-call health). I love teams that share knowledge routinely to help everyone learn and grow together.


I find that security goals are best achieved by understanding business goals and engineering challenges, and building cross-functional relationships on a foundation of trust.

What I value

I look for organizations that invest in building a healthy atmosphere of collaboration, teamwork, and mentoring. I prefer organizations that care about inclusion, equity, justice, and social impact: organizations that have demonstrated that inclusion is a profitable investment and refuse to tolerate persistently harmful behavior.


I care about working for teams and managers that invest in employee growth, in building trust, and in balancing quick wins with building scalable solutions.

Career Goals

I look for leadership roles within security organizations that value inclusion, compassion, and risk-informed security guidance: making the secure path easy, and avoiding authoritative approaches.


Long-term, I want to have an impact on making security and people management more humane, compassionate, and inclusive.
