Yotam Segev co-founded Cyera less than five years ago to solve real enterprise-level data security problems. Then, the world changed: as the AI boom took hold, data became an important fuel for companies to realize their AI dreams.
This puts Cyera in a critical position among organizations that need new data security and data management frameworks to protect a company’s information from multiple new threats, including proxy attacks, while enabling internal data to power new artificial intelligence applications.
“Our business predates artificial intelligence,” Segev said. “But with artificial intelligence, it grows wings.”
The wings have also boosted Segev startup valuations. June, Cyera worth US$6 billion It has entered the seventh round of financing. Now, just six months later, Cyera is worth $9 billion. Cyera raises $400 million in recently closed Series F funding round, company exclusively confirms wealth. black stone Growth led the round, with participation from existing investors including Accel, Coatue, Cyberstarts, Georgian, Greenoaks, Lightspeed Venture Partners, Redpoint, Sapphire Ventures, Sequoia Capital and Spark.

Cyera’s customers include AT&T, Peloton, Nordstromand Chipotlealthough the company declined to disclose its current financial results (it said in June that its annual recurring revenue had exceeded $100 million).
The funding is the latest sign of investors’ growing recognition of the importance of cybersecurity in the age of artificial intelligence, spawning a flurry of deals and a new crop of cybersecurity giant unicorns. The most famous of which is Wiz letter Agreed to acquire for a staggering $32 billion. Some of the other biggest deals in recent years have been in the cybersecurity space, including Palo Alto Network’s acquisition of CyberArk for a staggering $25 billion in 2025.
The current cybersecurity landscape is full of opportunities and anxieties, especially for large companies trying to find their way in a world where the threat landscape is rapidly expanding far beyond the reach of humanity.
“We are going after proxy attackers who will be more honed, more cohesive, more consistent and reliable in their actions and attacks carried out at millisecond speeds,” Segev said.
CEOs and executives at Fortune 1000 companies know that catastrophic breaches can and likely will cost them their jobs, he said. But because of the risks, business leaders cannot sit back and watch. In order to apply AI to large enterprises, large enterprises need to lock down their data infrastructure.
“If they don’t do data security well, they don’t have the ability to say ‘yes’ to AI in the way they want to,” Segev said.
