The implications of Frontier AI models for cyber defence

23 Apr 2026

National Cyber Security Centre

There has been significant commentary in recent weeks about the cyber security implications that Frontier AI models such as Mythos could mean for the cyber security community. 

The NCSC has developed some high-level advice to support senior leaders and network defenders to consider the implications of Frontier AI products.

As new vulnerabilities continue to be discovered, the best line of defence remains effective security controls. The NCSC recommends that organisations read the guidance and implement the advice provided.
