AI, Cybersecurity, and the Future of National Defense

Presented by NightDragon & Carahsoft

Dave DeWalt, Founder and CEO of NightDragon, delivered a stark assessment of how artificial intelligence is rapidly transforming cybersecurity and national defense. Speaking at Sea-Air-Space, DeWalt explained that recent advances in AI have dramatically increased both the opportunities and risks facing governments, militaries, and private industry.

DeWalt described 2026 as a turning point for AI capabilities, particularly with the emergence of advanced large language models capable of reverse engineering software binaries, identifying vulnerabilities, and building exploit chains in seconds. According to DeWalt, this represents a major shift in the cyber threat landscape because highly advanced offensive cyber capabilities are no longer limited to a handful of nation states. AI is flattening the technological playing field and allowing adversaries around the world to access tools that were once available only to the most advanced cyber powers.

The implications for national defense are significant. DeWalt warned that AI-powered cyber attacks can now target legacy systems across maritime, air, space, and critical infrastructure environments at unprecedented speed and scale. He stressed that governments and defense organizations must rapidly modernize defenses, harden code bases, and deploy autonomous defensive systems capable of responding at machine speed.

Despite these concerns, DeWalt also emphasized the enormous opportunities AI presents. He highlighted the growing use of autonomous systems, robotics, and AI-enabled maritime platforms across the defense sector. Companies are now building increasingly sophisticated autonomous vessels and intelligent systems capable of supporting military operations in ways that were unimaginable only a few years ago.

A central theme of the discussion was the need for guardrails and governance. DeWalt argued that while private industry will continue pushing technological innovation forward rapidly, governments have a responsibility to establish security standards and safety frameworks. He compared AI to the evolution of the automobile industry, where safety systems eventually became necessary as technologies advanced.

The discussion concluded with a look toward quantum computing, which DeWalt believes will become the next major disruption in cybersecurity and defense. While quantum computing offers tremendous processing capabilities, it also introduces serious risks related to encryption, communications security, and cyber resilience.
