Cybersecurity billionaire: Jay Chaudhry's journey from farms to fortune

Can success be achieved regardless of previous experiences? Jay Chaudhry, the 65-year-old founder of cloud security company Zscaler, has proven that it can. He took the risk of starting a business in the cybersecurity industry. Today, his net worth is estimated at $11.5 billion.

Chaudhry's story demonstrates how determination and market insight can lead to extraordinary success in the technology business. CNBC featured his story in a report.

Jay Chaudhry grew up in India in a family of small-scale farmers without a tradition of entrepreneurship. He studied engineering and marketing after moving to the United States in 1980. He then worked for technology giants like IBM and Unisys. He didn't initially plan to become an entrepreneur; the tech boom of the mid-90s inspired him to start his own company.

In 1996, Chaudhry, fascinated by Netscape's success, decided to resign from his position as a director at IQ Software. His wife, Jyoti, also resigned from her job as a systems analyst. Together, they invested all their life savings—about $500,000—in the startup SecureIT, which focused on cybersecurity software. They founded it in 1997.

The decision to start SecureIT was primarily based on Chaudhry's intuition. He noticed that with the growing popularity of web browsers, companies would need protection against online threats. At that time, less than 5 percent of the Fortune 500 companies used firewalls. In 18 months, SecureIT implemented firewalls in about 50 percent of the companies on this prestigious list.

This market insight proved to be spot on. In 1998, he sold SecureIT to VeriSign for nearly $70 million in stock. This success began a series of successful ventures in cybersecurity and e-commerce that Jay and Jyoti Chaudhry founded and sold over the next decade.

In 2007, already wealthy entrepreneurs, the Chaudhry couple decided to start "one big company" and focus all their attention on it. This is how Zscaler was born, a company helping businesses transition from outdated firewalls to the cloud era. Chaudhry invested $50 million of his own money in the project.

Zscaler turned out to be a tremendous success. Currently, the company generates annual revenues of $1.6 billion and has a market capitalization of about $30 billion. Forbes estimates Jay Chaudhry's personal wealth at $11.5 billion. This is an impressive increase compared to the $500,000 he invested in his first venture.

Chaudhry emphasizes that the key to success is a deep conviction in the rightness of your idea and the willingness to invest your own money. He advises aspiring entrepreneurs to thoroughly understand the field they want to enter and be ready to risk their own funds. According to him, investing your own money demonstrates genuine commitment and helps you make independent business decisions.
