Mythos and the New Cyber Frontier Masterclass

What Anthropic’s most powerful AI model means for your business; and how to stay ahead of it. In April 2026, Anthropic announced Mythos; an AI model so capable at finding and exploiting software vulnerabilities that the company chose not to release it to the public. Independent testing by the UK’s AI Security Institute found it could complete expert-level hacking tasks roughly three-quarters of the time, something no previous model could do at all. For business leaders, the question is no longer whether AI will reshape cyber security, but how quickly they need to respond. Join Nostra’s leadership team for a clear, jargon-free briefing on what Mythos really changes, what the genuine risks are versus the hype, and the practical steps Irish organisations should be taking now. What we've covered in this video: What Mythos is, and why an AI model was deemed “too dangerous to release” Separating real risk from headline noise; what the security community actually agrees on How AI-assisted attacks change the threat landscape for everyday businesses Practical defensive measures: where to focus budget, people and patching How Nostra is preparing clients for an AI-accelerated security era
