Adaptive Security has raised $81 million in a Series B funding round to enhance its AI-driven cybersecurity platform, addressing the burgeoning risks of AI-based impersonation and social engineering attacks.

Target Information

Adaptive Security, a pioneering cybersecurity firm, has secured $81 million in a Series B funding round led by Bain Capital Ventures, with contributions from NVentures, NVIDIA's venture arm, OpenAI Startup Fund, and several other prominent investors. This latest funding boost is part of a very active year for the company, bringing its total capital raised to $146.5 million. Since its public debut in January 2025, Adaptive has quickly attracted over 500 enterprise customers, including notable names like PayPal, Xerox, and the NHL. The company was co-founded by Brian Long and Andrew Jones, who previously led Attentive to generate around $500 million in annual revenue.

The impetus for founding Adaptive arose from witnessing a significant increase in AI-driven impersonation threats, which have evolved from rare occurrences to common risks. Traditional cybersecurity measures have proven inadequate against these emerging generative AI deceptions, prompting Adaptive to develop solutions specifically tailored for this challenge. Their innovative platform utilizes AI to simulate various impersonation tactics across multiple communication channels, enabling organizations to identify vulnerabilities and enhance employee awareness and training.
