Tanium, a leader in Autonomous IT, today announced that Co-Founder and Executive Chairman Orion Hindawi has been appointed Chief Executive Officer, effective immediately. Dan Streetman is stepping down as CEO and as a member of the Board after leading Tanium for the last three years, during which time Tanium scaled its go-to-market operations and secured strong industry analyst recognition for innovation within the Tanium platform. Streetman will continue to advise Tanium as part of the transition and co-founder David Hindawi will return to the role of Chairman of the Board. With this foundation in place, this transition positions Tanium to deepen its Autonomous IT capabilities and further expand AI offerings across its portfolio and strengthen customer and partner engagement.

The Hindawis co-founded Tanium in 2007 to build the central nervous system of enterprise security, giving organizations unified visibility and control over their endpoints. During his prior tenure as CEO from 2016 to 2023, Orion Hindawi delivered significant growth and built the technical architecture that today underpins one of the most trusted platforms in enterprise security – relied on by Fortune 500 companies, global financial institutions, defense agencies, and healthcare organizations worldwide. As one of the pioneering architects of enterprise-scale endpoint security and management, Hindawi is perfectly positioned to lead Tanium through this next important phase of growth.

“Tanium has built something genuinely rare – a platform trusted by the world’s most demanding organizations, with the technical depth to lead the next generation of enterprise IT,” said Orion Hindawi. “AI has made what we do more critical than ever, and Tanium is the platform every organization will rely on as threats grow more sophisticated, and the pace of change intensifies. We have already embedded AI across how we build and operate, as evidenced by Atlas, our autonomous operating system that was developed and released in a fraction of the time that would previously have been required. As we push further, I look forward to working closely with the talented Tanium management team to capture the meaningful opportunities ahead by delivering more value for our customers and partners.”

“On behalf of everyone at Tanium, I want to express our deep gratitude to Dan for his leadership over the past few years,” added Hindawi. “Dan led Tanium with integrity, steadiness and genuine care for this company, its customers, and its people. His contributions have strengthened Tanium and set the stage for the next chapter of growth. We thank him for his remarkable service.”

“It’s been a privilege to serve as CEO over the past three years and I’m proud of all we achieved, including improving operational discipline and supporting the important work of our customers, who are the most innovative and security conscious organizations in the world,” said Streetman. “I could not be more grateful to Orion, David and the Tanium Board for the trust they placed in me to lead this special company.”
