Steve, an enterprise sales veteran with over 17 years of experience, brings an exceptional track record of driving revenue growth and exceeding targets at high-growth SaaS and cybersecurity organizations.

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.  Steve has consistently demonstrated his ability to build strategic relationships with Fortune 500 clients and has closed numerous multi-million dollar campaigns.

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. His expertise in the cybersecurity domain, plus his experience working in high growth sales organizations, positions him perfectly to drive SquareX's continued growth in the rapidly expanding and ever changing browser security landscape.

"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."

"Steve's outstanding track record of exceeding targets and building strategic relationships with enterprise clients makes him an ideal leader to accelerate SquareX's enterprise growth. His experience at high-growth companies, combined with his deep understanding of enterprise security challenges will be invaluable as we continue our expansion plans and help organizations secure their browser environments against bad actors," said Vivek Ramachandran, Founder and CEO of SquareX.
