Common questions
What is The Brief?
A bi-weekly CISO intelligence brief covering agentic AI threat developments, MCP infrastructure exposure, authority gap signals, and vendor landscape intelligence. Formatted to TLP:AMBER standard. Written for decision-makers, not analysts.
What is the authority gap?
The unvalidated window between when an AI agent receives a directive and when it executes. Authentication confirms identity. Authorization defines access. Neither validates whether the specific directive being executed has legitimate authority behind it at that specific moment. That’s the gap. That’s what this brief documents.
Who is this for?
CISOs and CIOs at organizations with agentic AI in production or in evaluation. If your board is asking about AI security posture and you need a framework to answer them, this is that framework.
When is the peer network live?
Q3 2026 target. Members get first access. Invite-only and human-reviewed — same standard as the brief itself.
Looking for enterprise access or a Discovery Engagement?
Discovery Engagements are scoped authority gap assessments that produce board-ready documentation. Four per quarter. Limited availability.
