Adaptive Security Raises $55m with OpenAI Support

Adaptive Security, a cybersecurity firm specializing in AI-driven social engineering prevention, has extended its Series A round to raise $55 million total. The OpenAI Startup Fund provided the follow-on investment, making Adaptive its first and only cybersecurity-backed company to date. This move demonstrates strong confidence in Adaptive’s technology and mission to combat emerging AI-driven deception.

People-First Security Approach

Founded to fight growing identity theft and fraud threats, Adaptive takes a people-first security approach. Its platform uses AI-generated voice, video, and message simulations to replicate phishing and deepfake attacks. These simulations prepare individuals and institutions for new cyber risks. Furthermore, the platform provides personalized training, real-time threat assessment, reporting, and AI-powered risk scoring. This complete approach helps organizations respond effectively to complex threats.

Addressing Growing AI Fraud Concerns

This funding arrives during increasing concern about AI-powered fraud. Recent incidents include AI-generated messages pretending to be senior U.S. officials and fake videos targeting the public. Additionally, voice-copying scams cost Michigan residents over $240 million in 2024. Even OpenAI CEO Sam Altman has warned about a coming “fraud crisis,” criticizing old authentication methods like voiceprints.

Future Plans and Industry Impact

With this new funding, Adaptive will speed up product innovation and expand defenses against AI-powered impersonation attacks. CEO Brian Long emphasized that “cybersecurity now begins with people, not just infrastructure.” He noted that trust itself could become the biggest weakness in an AI-driven world.

OpenAI Startup Fund partner Ian Hathaway praised Adaptive’s fast approach. He highlighted the company’s realistic deepfake simulations, risk scoring, and effective training as exactly what modern security teams need. With OpenAI’s support, Adaptive positions itself as a leader against AI-powered deception, setting new standards for cybersecurity strength.

This investment represents important support for Adaptive’s approach to fighting increasingly sophisticated AI-driven threats. As artificial intelligence becomes more available to harmful actors, solutions that prepare organizations and individuals through realistic simulations and training become more vital. The partnership between Adaptive Security and OpenAI signals growing recognition that traditional security measures alone cannot handle the special challenges posed by AI-generated social engineering attacks.
