Adaptive Security Raises $81 Million Series B To Combat AI Threats

Adaptive Security, a fast-growing cybersecurity company focused on defending organizations against AI-driven and crypto-related threats, has raised $81 million in a Series B funding round led by Bain Capital Ventures. The massive investment signals strong market confidence in the company’s mission to counter the rapidly evolving landscape of artificial intelligence powered cybercrime.

The funding round places Adaptive Security among the most well-capitalized players in the emerging AI cybersecurity defense market, as enterprises globally struggle to keep pace with increasingly sophisticated digital attacks.

Growing Threats Drive Demand for AI-Powered Cybersecurity

Cybersecurity threats are evolving faster than ever, driven largely by generative AI tools that enable attackers to automate phishing, impersonation, and social engineering attacks at unprecedented scale. Deepfake voice calls, AI-generated emails, and multi-channel scams have become common attack vectors, exposing critical weaknesses in traditional security models.

Adaptive Security addresses this challenge by focusing on the human layer of cybersecurity. Its platform uses artificial intelligence to simulate realistic attack scenarios, helping organizations train employees to recognize and resist threats before damage occurs. This proactive approach positions the company at the center of the AI-powered cyber threat prevention industry.

Strategic Backing From Top Venture Capital Firms

The Series B round was led by Bain Capital Ventures, with participation from several prominent technology and financial investors. The strong investor lineup reflects a growing belief that AI-first security platforms are essential as cybercriminals increasingly rely on automation and machine intelligence.

With this latest raise, Adaptive Security has significantly expanded its total funding, giving it the resources needed to compete aggressively in the global cybersecurity market and respond to rising enterprise demand for smarter, faster protection.

Focus on Crypto and Digital Asset Defense

Beyond traditional enterprise security, Adaptive Security is expanding its focus on crypto and digital asset defense, an area experiencing heightened risk. As blockchain adoption grows across finance, payments, and decentralized applications, attackers are increasingly targeting crypto wallets, private keys, and smart contracts.

The company’s technology is designed to help organizations secure sensitive digital assets by identifying behavioral vulnerabilities and strengthening internal defenses against social engineering attacks that often precede crypto breaches. This dual focus on enterprise and crypto security differentiates Adaptive Security in a crowded market.

How Series B Funding Will Be Used

The $81 million Series B capital will be used to accelerate product innovation, scale operations, and expand Adaptive Security’s global footprint. A significant portion of the funding will support research and development, particularly in advanced AI modeling, behavioral analytics, and threat simulation.

The company also plans to grow its workforce, hiring across engineering, data science, and cybersecurity research roles. This expansion aims to keep pace with rapidly evolving attacker techniques while maintaining high accuracy in threat detection and prevention.

Positioning in a Competitive Cybersecurity Market

The cybersecurity sector has seen a surge in venture investment as organizations prioritize protection against AI-enabled attacks. However, many existing tools remain reactive, addressing threats only after systems have been compromised.

Adaptive Security’s emphasis on prevention, education, and adaptive learning gives it a competitive edge. By continuously updating simulations based on real-world attack data, the platform evolves alongside threat actors, offering organizations a dynamic and resilient defense strategy.

Looking Ahead for Adaptive Security

With fresh capital and strong investor backing, Adaptive Security is entering a critical growth phase. The company is positioned to become a key player in shaping how enterprises defend against AI-driven cybercrime and crypto-related attacks.

As artificial intelligence continues to transform both offensive and defensive cybersecurity capabilities, Adaptive Security’s latest funding round underscores a clear industry trend: the future of cyber defense will be adaptive, AI-powered, and human-centric.
