AI-Powered Defense: Adaptive Security Lands on Fortune’s Cyber 60, Signals Shift in Cybersecurity

NEW YORK – November 1, 2025 – In a landscape increasingly defined by AI-powered threats, Adaptive Security has emerged as a key innovator, earning a spot on Fortune’s annual Cyber 60 list. The company, backed by the OpenAI Startup Fund, is pioneering a new generation of defenses against social engineering attacks – a critical area often overlooked in traditional cybersecurity strategies.

Adaptive Security’s inclusion on the list, developed in partnership with Lightspeed Venture Partners and AWS, underscores a growing recognition that the battle for digital security is now inextricably linked to artificial intelligence. While AI is being weaponized by attackers, it’s also proving to be a powerful tool for defenders – and Adaptive Security is at the forefront of this shift.

The Evolving Threat Landscape

Traditional cybersecurity has long focused on perimeter defenses – firewalls, intrusion detection systems, and anti-malware software. However, these defenses are increasingly ineffective against sophisticated social engineering attacks, which exploit human psychology to bypass technical controls. The rise of generative AI is amplifying this threat exponentially.

“We're seeing a significant escalation in the sophistication of social engineering attacks,” explains a cybersecurity consultant specializing in threat intelligence. “Attackers are now leveraging AI to create hyper-personalized phishing emails, deepfake videos, and voice clones that are virtually indistinguishable from the real thing. It’s no longer about spotting obvious errors; it’s about discerning subtle cues that even seasoned professionals can miss.”

This new generation of attacks relies on exploiting vulnerabilities in human behavior, making it incredibly difficult to defend against with traditional methods. Adaptive Security is tackling this challenge by focusing on building resilience within the workforce – training employees to recognize and respond to emerging threats.

AI-Native Defense: Simulating the Real World

Adaptive Security’s platform combines next-generation security awareness training with realistic AI-powered attack simulations. Unlike traditional training modules that rely on static content, Adaptive Security’s simulations adapt to individual user behavior, creating a personalized learning experience. The platform can simulate a wide range of attacks, including deepfake phishing emails, voice cloning scams, and OSINT-powered spear phishing campaigns.

“The key is to move beyond awareness and into preparedness,” says Brian Long, CEO of Adaptive Security. “Employees need to be exposed to realistic attack scenarios so they can learn to recognize the red flags and respond appropriately. Our platform provides a safe environment for employees to practice their skills and build their confidence.”

The platform also incorporates real-time employee risk analysis, identifying individuals who are most vulnerable to social engineering attacks based on their online behavior and social media activity. This allows security teams to focus their training efforts on those who need it most.

OpenAI’s Strategic Investment

The backing from the OpenAI Startup Fund is a significant validation of Adaptive Security’s approach. OpenAI, the creator of ChatGPT and other groundbreaking AI models, is actively investing in companies that are developing innovative applications of AI. Their investment in Adaptive Security suggests a belief that AI-powered social engineering prevention is a critical component of the future of cybersecurity.

“OpenAI recognizes that AI is a double-edged sword,” states a venture capitalist specializing in cybersecurity. “They’re committed to developing AI technologies responsibly, and that includes investing in companies that are helping to mitigate the risks of AI-powered attacks. Adaptive Security is a perfect fit.”

While the specific details of the collaboration remain confidential, sources indicate that OpenAI is providing Adaptive Security with access to its cutting-edge AI models and expertise in machine learning. This allows Adaptive Security to stay ahead of the curve and develop defenses against the latest AI-powered threats.

Beyond Technology: A Human-Centered Approach

While technology plays a crucial role in Adaptive Security’s platform, the company emphasizes the importance of a human-centered approach. Their training programs are designed to not only educate employees about the technical aspects of social engineering attacks but also to empower them to make informed decisions and protect themselves.

“It’s not enough to simply tell employees what to look for,” explains a security awareness trainer who has integrated Adaptive Security's platform into her curriculum. “They need to understand the psychology behind these attacks and learn how to think critically. Adaptive Security’s platform provides a valuable tool for reinforcing these concepts and building a security-conscious culture.”

The Future of Cybersecurity

Adaptive Security’s success highlights a growing trend in cybersecurity: the need for more proactive and adaptive defenses. As AI continues to evolve, the stakes for digital security will only increase. Companies that are able to leverage AI to protect themselves – and to empower their employees – will be best positioned to thrive in the years ahead.

The $55 million Series A funding round, which includes continued investment from OpenAI and Andreessen Horowitz, provides Adaptive Security with the resources to expand its platform and reach a wider audience. The company plans to invest in research and development, expand its training programs, and build partnerships with leading cybersecurity organizations.

As the lines between offense and defense continue to blur, Adaptive Security is leading the charge in the fight against AI-powered cyberattacks – and paving the way for a more secure digital future.
