Former Dropbox CFO, who helped take the company public, joins as Delinea scales
its identity security platform for the AI era
SAN FRANCISCO – September 23, 2026 – Delinea, the identity security platform that continuously controls what AI agents, humans, and machines can do and for how long, today announced the appointment of Timothy Regan, CPA, as Chief Financial Officer. Regan joins the executive team to sharpen Delinea's commercial and operational discipline as the company continues to scale.
Regan brings more than two decades of financial leadership across high-growth technology companies. He most recently served as Chief Financial Officer of Dropbox from 2020 to 2025 and subsequently as an advisor to the company through early 2026. He joined Dropbox in 2016 as Chief Accounting Officer, and helped guide the company through its 2018 IPO. Earlier in his career, Regan served as VP Finance Controller at Pandora Media and held senior finance positions at Dolby Laboratories and Ernst & Young LLP.
"AI is significantly expanding the identity security market," said Art Gilliland, CEO at Delinea. "As agents take on more work across the enterprise, organizations count on Delinea to control what those agents are allowed to do. Tim brings deep experience in building systems for scale and operational rigor that will help us capture the opportunity in front of us."
"AI is turning identity into the control point for enterprise security, and Delinea has the platform and the customer base to lead that market," said Regan. "I've spent the past decade building finance organizations that hold up under scrutiny, and I look forward to bringing that operational discipline to Delinea."
Regan holds a bachelor's degree in accounting from Georgetown University and an MBA from the Haas School of Business at the University of California, Berkeley.
