The AI Security Baseline Has Shifted. Your Early Warning System is Loading.
On June 9, 2026, Anthropic released the Mythos-class models, fracturing the landscape into two realities: Fable 5 for the public, and the unrestricted Mythos 5 for elite cyber defenders.
AI can now find, exploit, and patch zero-day vulnerabilities in hours, not months. The window between discovery and exploitation is closing. Mythos Alert is being built to keep you ahead of the curve.
⏳ We are launching soon. Don't be the last to know.
Join the exclusive waitlist to get real-time intelligence on the Anthropic Mythos ecosystem the moment we go live.
🛡️ Why Mythos Alert?
When an AI can identify a 27-year-old flaw in secure systems and patch thousands of vulnerabilities in a matter of weeks, the old rules of threat intelligence no longer apply. We are building a dedicated intelligence hub to track the shockwaves of this release, providing you with actionable insights, not just noise.
📡 What to Expect Upon Launch:
The Glasswing Tracker: Curated updates and analysis on the thousands of vulnerabilities being unearthed by the 150+ organizations in Anthropic’s Project Glasswing.
Fable 5 Defense Strategies: Tactical guides on how to adapt your engineering and security pipelines to handle the influx of AI-generated code and potential bypass techniques.
Zero-Day Intelligence: Real-time alerts on significant industry shifts, patch cycles, and identity security recommendations driven by Mythos-class discoveries.
Policy & Access Updates: The latest on Anthropic's data retention policies, capability upgrades, and how to navigate the evolving restrictions between Fable 5 and Mythos 5.
"The window between vulnerability and fix is now a critical battleground."
