What frontier models mean for enterprise cybersecurity

Frontier AI models are accelerating the pace and scale at which vulnerabilities can be discovered and exploited by threat actors. Capabilities once limited to highly skilled specialistswill now be used by AI-driven threat actors to target enterprise software ecosystems at volume, scale and sophistication as never before.

Enterprises can no longer assume that mature or previously tested systems are low risk, and the bottleneck has moved from finding vulnerabilities to prioritizing, managing and resolving them at speed.

In this perspective, we explore what the emergence of frontier models signals toCISOs, CIOs and security leaders— and why the real challenge is not access to any single model but readiness for a fundamental shift in the threat environment shaped by advanced AI models.

We also give guidance on how security leaders should use advanced AI models to strengthen their cyber defense, software assurance, remediation operations, governance and enterprise resilience to respond effectively.
