Daniel Dubowski joined Marriott International in August 2026 as Senior Vice President and Chief Information Security Officer, covering North America. He previously served as SVP & CISO at Hertz from March 2024, where he led the car rental company’s cybersecurity strategy for more than two years.
A career built around information security
Before Hertz, Daniel Dubowski spent nearly six years at Equifax, where he rose through the ranks to become Chief Information Security Officer of the USIS division between January 2022 and March 2024, having previously held the roles of Vice President, BISO USIS, and Vice President for identity, access and cryptography management.
Marriott’s new CISO is no stranger to the hospitality sector: he spent more than four years at InterContinental Hotels Group (IHG), where he led global IT security – networks, operations, IAM, SOC – from January 2016 to August 2018, overseeing the day-to-day cybersecurity of a group that at the time operated more than 5,300 hotels with around 30,000 employees and 420,000 digital identities. Before that, he held the role of Director of Security Assurance at IHG from May 2014.
His career began in more generalist IT roles, notably at D.R. Horton, the American homebuilder, where he spent nearly seven years as IT Operations Manager and then Security Architect, following an earlier position as Sr. Systems Administrator at Cambridge Homes from 2003. He holds an MBA from the Georgia Institute of Technology (2020-2021) and two bachelor’s degrees from the University of Illinois at Urbana-Champaign, in Computer Science and Mathematics.
A profile praised by Marriott’s technology leadership
“Dan brings deep experience leading cybersecurity and risk management programmes across hospitality, travel, financial services and healthcare”, said Naveen Manga, Global Chief Information Officer at Marriott International, announcing the appointment of Daniel Dubowski. He noted that Dubowski’s leadership would be key to strengthening trust and resilience across the group globally, amid ongoing technological transformation guided by security- and trust-by-design principles.
An increasingly strategic role in hospitality
The arrival of Daniel Dubowski at Marriott reflects a broader trend across the sector: major hotel groups are strengthening their executive teams dedicated to cybersecurity as cyberattacks targeting hospitality infrastructure become more frequent. Wynn Resorts, for example, had appointed Troy Wilkinson as Global CISO in April 2026, underscoring the growing importance placed on this role within hotel and leisure groups.
This appointment also forms part of a wider series of governance reinforcements across the Marriott ecosystem, which earlier this year also appointed Vladimir Anokhin as Chief Strategy & Transformation Officer at Marriott Vacations Worldwide.
