AI-driven security awareness training platform protecting enterprises from generative AI threats like deepfakes & voice cloning.
Adaptive Security is a provider of artificial intelligence-driven security awareness training that protects enterprise organizations from generative AI-enabled threats such as deepfakes and malicious voice cloning. Rather than utilizing traditional static educational modules, the platform delivers customized simulated attacks across voice, video, and text channels to help corporate employees identify and respond to emerging synthetic media vulnerabilities. The venture-backed software-as-a-service company operates with a workforce of over 150 employees and has acquired more than 500 enterprise customers since its official public launch in January 2025. Backed by over $145 million in total venture funding, including an $81 million Series B round, the firm has successfully attracted investments from Sequoia Capital and Bain Capital Ventures while serving notable clients such as PayPal, Xerox, and Figma. Adaptive Security was founded in 2024 by Brian Long and Andrew Jones.

Adaptive Security is a cybersecurity startup building an AI-native platform for security awareness training and phishing simulations tailored to counter emerging AI-powered threats like deepfakes, generative AI phishing, vishing, and smishing[2][3][8]. It serves enterprises, including Fortune 500 companies and organizations like the Dallas Mavericks, by solving the problem of outdated training that fails against sophisticated social engineering attacks, delivering hyper-realistic simulations, customizable interactive modules, and dynamic risk scoring to reduce human risk and build resilient security cultures[3][4][6]. With strong growth momentum—evidenced by high customer satisfaction (100% in some cases), rapid onboarding, and adoption by teams training thousands of employees—the company is backed by Andreessen Horowitz and the OpenAI Startup Fund, positioning it as a leader in next-gen cybersecurity training[2][3][4].
Adaptive Security was founded by CEO Brian Long, who leads the company's focus on innovating security awareness training amid rising AI-driven threats[8]. The idea emerged from recognizing the rapid evolution of attacks like deepfake voice calls, GenAI phishing, and vishing, which traditional platforms couldn't effectively simulate or train against, prompting the development of an AI-powered solution that integrates open-source intelligence (OSINT), realistic personas, and automated content creation[2][3][8]. Early traction came through quick enterprise adoption, with customers praising seamless onboarding and immediate impact on employee engagement and phishing recognition rates, as seen in reviews from security leaders training 600+ to 13,000+ employees[3][6].
Adaptive Security rides the wave of AI-augmented cyber threats, where generative AI enables hyper-personalized social engineering that bypasses traditional defenses, making human-focused training essential in a landscape shifting toward adaptive, Zero Trust models[1][2][5]. Timing is critical as deepfakes and vishing proliferate—market forces like regulatory pressures (e.g., compliance mandates) and rising breach costs favor platforms that deliver measurable risk reduction via automation and real-time adaptation[1][4][5]. It influences the ecosystem by elevating security awareness from checkbox exercises to proactive, data-driven programs, fostering cultures resilient to AI risks and complementing tools like SOAR for faster responses[1][3][5].
Adaptive Security is poised to dominate AI-threat training as attacks grow more sophisticated, with expansions in OSINT integration, multichannel simulations, and predictive analytics likely driving further enterprise adoption[2][4]. Trends like Zero Trust maturation and AI regulation will amplify demand, potentially evolving its influence toward full-spectrum human risk platforms that integrate with endpoint detection. This positions Adaptive not just as a training vendor, but a core partner in modern cybersecurity, directly addressing the human element in an era where AI threats outpace static defenses—echoing its mission to protect businesses from the next generation of attacks[1][3][7].
