It's a zero trust framework, and it arrives at a key moment. On one side we're handing agents far more access, more autonomy and more freedom to just go and act on their own. On the other, the cost of an attack has collapsed, especially as frontier models like Claude Mythos and OpenAI's Sol get genuinely capable at surfacing security vulnerabilities. An exploit that used to take a specialist months can now be brute-forced by a coding agent in the wrong hands, working around the clock. So in this video I boil the whole thing down to what actually matters for the agents you run, whether that's Claude Code or a custom agent you're building on any platform. #AI #AIAgents #AISecurity #ZeroTrust #ClaudeCode #LethalTrifecta #PromptInjection #MCP #Anthropic #OWASP #AIArchitects #AIBuilder
