The $9 billion cybersecurity firm has been facing competition from AI.

Tanium is turning back to its roots.

The $9 billion cybersecurity company is bringing back cofounder Orion Hindawi as CEO, replacing Dan Streetman after less than four years in the role, as the company looks to navigate the AI upheaval reshaping software companies.

Hindawi's father and another cofounder, David Hindawi, will return to the role of chair, while Streetman leaves the company's board.

Prior to Streetman joining the company, Orion Hindawi served as CEO for over 15 years.

Tanium also had a small round of job cuts last week, affecting around 35 employees in research and development, according to sources familiar with the matter.

According to a corporate fact sheet, Tanium had 1900 employees as of 2025.

Like many software-as-a-service (SaaS) companies, Tanium has been facing more competitive pressure as AI changes how businesses buy and use enterprise software.

The company said it plans to expand its AI offerings and autonomous capabilities.

This leadership shake-up follows several executive departures this year, as Business Insider previously reported.

Tanium has stayed private since its founding in 2007, and it was last valued at $9 billion in 2020.
