Stripe CFO brings deep cybersecurity and public company experience as Cyera builds for independence at scale

Cyera, the AI Security Platform built for the age of agents, today announced the appointment of Steffan Tomlinson, CFO at Stripe, to its Board of Directors.

A seasoned technology CFO and operator, Steffan has helped lead multiple companies through periods of rapid growth. He brings deep experience in security, enterprise scale, and financial leadership at a time when AI is reshaping how organizations think about data and risk.

“As AI systems and agents take on a bigger role in how businesses operate, the way we think about data security has to evolve with it,” stated Steffan. “Risk is no longer static, and controlling how data is accessed and used becomes critical. Cyera is building for that shift, and I’m looking forward to working with the team as they scale.”

As enterprises adopt AI, data risk is becoming constant. Sensitive data is moving across cloud environments, internal systems, and third parties, while AI systems and autonomous agents are accessing and acting on it in real time. Security leaders are under pressure to keep up—not just to know where data lives, but how it’s used, who can access it, and how that risk changes over time. With experience overseeing security, technology, and risk in complex environments, Steffan brings firsthand experience managing these challenges as Cyera continues to grow with the world’s largest enterprises.

“Scaling a company today means getting data and risk right from the start, especially as AI and autonomous systems become core to how businesses operate,” said Joseph Iantosca, CFO at Cyera. “Steffan has spent his career in environments where those decisions matter, and his perspective will be a strong addition as we continue to grow.”
