In 2026, the cybersecurity landscape is undergoing a significant transformation driven by the increasing use of agentic artificial intelligence (AI) by threat actors. Agentic AI, defined as AI systems capable of autonomous decision-making and action execution, has become a critical disruptive technology intersecting cybersecurity, defense tech, and AI development.

At the recent RSA Conference (RSAC) 2026, industry leaders and Chief Information Security Officers (CISOs) debated the dual-edged sword of AI in cybersecurity—balancing its capabilities for defense with the escalating sophistication it grants attackers. This dialogue highlights the urgent challenge of scaling human involvement in security decision-making as AI tools become more autonomous and complex.

Agentic AI enables cyber attackers to automate and optimize attack campaigns at an unprecedented scale and speed. Traditional vulnerability discovery methods were labor-intensive, slow, and often financially unrewarding for researchers. As noted in a recent Fitch briefing on cyber risk, AI fills these gaps effectively, amplifying the financial and operational impact of cyber threats.

The operational shift means cybersecurity defenses must quickly adapt to counter intelligent, dynamic threats that evolve using agentic AI capabilities. Malware, phishing, and other attack vectors are now powered by AI agents that can make real-time decisions without human input, enhancing evasion and target selection.

However, this rapid adoption is not without risks and controversies. Fitch’s analysis warns that while AI offers immense potential to disrupt cyber risk management positively, there remain short-term vulnerabilities and unknowns within AI-driven cybersecurity that adversaries could exploit.

Additionally, public trust in AI deployments within defense and security sectors faces severe test scenarios. OpenAI’s agreement to deploy its AI on U.S. Department of Defense classified networks triggered a massive public backlash exemplified by the #QuitGPT movement, which amassed over 2.5 million supporters, and a 295% spike in ChatGPT uninstalls overnight. This outcry reflects broader societal concerns about oversight, ethics, and transparency in AI-powered defense applications.

The evolving trend of integrating agentic AI into cyberattack methodologies was also forecasted by key security commentators earlier this year. Alex Cox, TIME director and AI specialist, predicted in January that threat actors would increasingly integrate agentic AI, reshaping the threat landscape throughout 2026.

Given these dynamics, cybersecurity professionals face the complex task of developing strategies that blend human intuition and adaptability with AI’s automated capabilities. This hybrid approach aims to maintain agility in cyber defense while managing ethical, operational, and security ramifications.

For organizations and governments, investment in AI-aware security infrastructure will be pivotal in protecting assets from increasingly intelligent and autonomous threats. Policies and frameworks ensuring responsible AI use, transparency in deployment, and collaboration across sectors are equally critical to maintaining trust and effective defense.

In summary, 2026 marks a pivotal year where agentic AI presence in cybersecurity is not just augmenting existing tactics but fundamentally reshaping the threat landscape. Stakeholders across technology, security, and policy domains must grapple with this transformative wave to safeguard digital infrastructures and societal trust alike.
