Adaptive Security Raises $81 Million in Series B Funding

Led by Bain Capital Ventures, the investment round brings the total raised by the company to $146.5 million.

Cybersecurity funding

Adaptive Security has announced raising $81 million in a Series B funding round, the third investment round since its official launch in January.  To date, the company has raised $146.5 million.

The funding round was led by Bain Capital Ventures, with additional support from NVentures, OpenAI Startup Fund, Andreessen Horowitz (a16z), Abstract Ventures, Capital One Ventures, and Citi Ventures.

Founded in 2024, New York-based Adaptive Security aims to combat AI-powered cyber threats such as deepfakes, vishing, smishing, and gen-AI email attacks.

Adaptive Security’s platform runs AI-powered simulations of deepfakes and impersonation attacks across communication channels to identify weak controls and provide tailored training based on employee responses.

The company relies on open source intelligence and company-specific data to identify attack venues, then builds AI-powered attack simulations targeting an organization’s employees.

For employees who fail the simulations, Adaptive Security can restrict controls and provide personalized training so they can learn how to identify deepfakes of their executives and highly tailored scams.

According to the company, its interactive training modules help build real-world skills in security and compliance, while ensuring that employees are better prepared to spot emerging AI-driven threats.

Through risk scoring and automated threat triage, it enables organizations to identify weak spots in their employee base and processes based on real user behavior.

Adaptive Security’s training and phishing platforms are available in over 39 languages, include accessibility controls and role-based administrative access, and can be integrated into existing SaaS tools.

“Over the past year, we have watched AI impersonations evolve from experimental to everyday. A few seconds of audio or a short video clip is now enough for anyone to generate a convincing clone. That shift forces organizations to prepare for scenarios where even familiar voices, faces, or messages can no longer be taken at face value,” Adaptive Security co-founder and CEO Brian Long said.
