Steve’s career is distinguished by his consistent top performance and strategic leadership at some of the industry’s most successful technology companies such as Wiz, Okta, EMC and more. Most recently he served as Strategic Account Executive at Wiz for the past four years — the fastest-growing SaaS company to reach $10 billion valuation — his five-year tenure at Okta as Regional Sales Manager for Large Enterprises spanning the company’s IPO period gave him his first opportunity to experience high velocity growth from pre-IPO to over $1 billion in yearly revenue.

In his newly appointed role as VP of Sales, Steve will lead SquareX’s enterprise sales strategy & GTM operations, focusing on accelerating customer acquisition and market expansion.

“I am excited to join SquareX at such an exciting time in the company’s growth journey,” said Steve Mullett. “The browser has become the new attack surface for enterprises, and SquareX’s innovative approach to browser security with the ability to secure any browser on any device along with providing holistic browser DLP and a next generation approach to secure access addresses a critical gap in the market that every security leader is struggling with. Having worked with enterprise security teams throughout my career, it is the perfect time for me to apply my experience at SquareX and help companies of all sizes navigate the challenges they face with evolving browser-native threats to transform their security posture.”
