Introduction to Adaptive Security
Adaptive Security, a leading provider of AI-powered social engineering prevention solutions, has announced that it has raised an $81 million Series B funding round led by Bain Capital Ventures, with participation from notable investors such as NVIDIA, OpenAI Startup Fund, and Andreessen Horowitz. This investment brings the company’s total capital raised to $146.5 million, reflecting growing investor concern over AI-powered cyber threats. Adaptive Security’s rapid fundraising activity is a testament to the rising concern among investors and customers about the increasing threat of AI-powered cyber attacks.
The Rise of AI-Powered Cyber Threats
The company’s founders, Brian Long and Andrew Jones, started Adaptive Security after recognizing the growing threat of AI-enabled impersonation, which has evolved from a niche risk to a practical problem for companies, employees, and consumers. AI impersonation threats have accelerated in recent years, with deepfake incidents growing 17 times from 2023 to 2024, and more than 100,000 occurring in the U.S. alone. In 2025, Adaptive reported a rise in AI deepfake activity, with more than half of its customer discussions including reports of deepfake incidents. These incidents affect employees across all levels of an organization and increasingly affect consumers through cloned voices, fabricated videos, and personalized scams.
Adaptive Security’s Solution
Adaptive Security uses AI to simulate deepfake and impersonation scenarios across voice calls, text messages, video, and email. These simulations identify where existing controls are likely to break down and provide individualized training based on employee responses. The platform also includes automated threat triage and AI-driven executive risk scoring to help organizations identify their most exposed teams and processes. By combining advanced AI simulations, real-time risk assessment, and security awareness training, Adaptive empowers organizations to proactively defend against emerging cyber threats. The company’s solution is designed to give organizations clarity in a landscape that is changing extremely quickly, with the threat evolving in real-time.
Investor Support and Validation
The investment from NVIDIA, OpenAI Startup Fund, and other leading investors is a validation of Adaptive Security’s approach to next-gen security. The company’s focus on AI-powered social engineering prevention solutions has resonated with investors, who recognize the growing threat of AI-powered cyber attacks. Enrique Salem, partner at Bain Capital Ventures, noted that the surge in AI-enabled threat vectors has elevated human-layer security to a board-level priority, and Adaptive is emerging as the platform organizations rely on to stay ahead of these threats. The investment will help Adaptive Security advance its efforts to secure AI systems and protect the people who work with them.
Company Growth and Customer Adoption
Adaptive Security has experienced rapid growth since its public launch in January 2025, with over 500 enterprise customers and a world-class NPS score of 94. The company’s customers include notable organizations such as PayPal, Xerox, Bose, the National Hockey League, and the Professional Golfers’ Association. Adaptive Security’s customer base is a testament to the growing demand for effective solutions to combat AI-powered cyber threats. The company’s ability to provide individualized training and risk assessment has resonated with customers, who recognize the need for proactive defense against emerging cyber threats.
