OpenAI Makes First Cybersecurity Bet with $43M Adaptive Investment

A new cybersecurity startup just raised $43 million to tackle a growing threat: AI-powered impersonation attacks. Adaptive Security landed funding from Andreessen Horowitz and OpenAI's startup fund.

The company spotted a critical problem. Attackers now use AI to create fake versions of executives and employees. These AI personas can call, email, or text workers using voice and language that sounds real. The goal? Steal money, data, or plant ransomware.

Brian Long, Adaptive's CEO, builds defenses that fight AI with AI. His platform creates simulated attacks to train employees. When someone gets a fake call from "the controller" asking for a wire transfer, it's actually a test. If they fall for it, they get instant training.

The company's approach works. Since launching in January, they've signed over 100 enterprise customers including the Dallas Mavericks and First State Bank.

For OpenAI, this marks their first investment in cybersecurity. Ian Hathaway from the OpenAI Startup Fund explains why: "AI is reshaping cybersecurity threats faster than most organizations can respond."

Adaptive uses the funding to grow their research team. They're building tools that spot threats in real-time and help security teams act fast. The investment shows the urgent need for better defenses. As AI gets smarter, impersonation attacks grow more convincing. Traditional security training can't keep up with deepfakes that sound and act like real people.

The company's platform goes beyond just attack simulations. It scores risk across teams and creates custom training content. Security teams get a live map of their weaknesses before attackers exploit them.

Why this matters:

  • AI-powered attacks mark a shift from occasional phishing to industrial-scale deception
  • When attackers use AI to impersonate executives, fighting back requires AI-powered defenses
