Mythos is a signal, not a siren: What frontier AI should change for CISOs

That is why I view Mythos as a signal, not a siren. It signals that the economics of cyber offense and defense are changing. It does not signal that security fundamentals no longer matter. If anything, it proves the opposite. The organizations that have clear asset visibility, disciplined patching, strong identity controls and resilient operating models will be in a far better position to absorb whatever AI changes next.

That perspective matters because recent breach reporting still points to familiar failure points. Verizon’s 2025 Data Breach Investigations Report shows that credential abuse and vulnerability exploitation remain central themes in how organizations get compromised, with exploitation continuing to rise. In other words, the path into the enterprise is still usually paved by weaknesses security teams already understand.

The real problem is still the basics

In my experience, many organizations do not have a strategy problem as much as they have an execution problem. Security leaders know the basics. Their teams know the basics. Their auditors, regulators and board committees know the basics. The struggle is sustaining those basics consistently across hybrid estates, aging systems, cloud platforms, remote users and sprawling third-party dependencies.
