VectorCertain LLC today announced the completion of manuscript-prep for The MYTHOS Playbook, a 34-chapter, 9-appendix technical reference designed for CISOs, security architects, and AI governance program leads operationalizing the new joint Five Eyes guidance on agentic AI security. The book closes its 17-sprint development cycle and proceeds to June 2026 publication. A pre-order landing page is live at vectorcertain.com.
The Five Eyes joint guidance, "Careful Adoption of Agentic AI Services," was published May 1, 2026, by CISA, NSA, Australia's ASD ACSC, the Canadian Centre for Cyber Security, NZ NCSC, and UK NCSC. It identifies five risk classes: privilege, design and configuration, behavioral, structural, and accountability. The MYTHOS Playbook converts these policy-level recommendations into specific architectural patterns, statistical detection methodology backed by 7,000 adversarial scenarios at ≥99.65% 3-sigma confidence, vendor RFP language, and a 119-cell framework cross-walk.
The market context is severe: one in eight enterprise breaches now involves AI agents, a 340% year-over-year increase, with 78% of compromised agents over-permissioned. Gartner projects AI agents will be embedded in 40% of enterprise applications by end of 2026. The Five Eyes guidance opens with the observation that agentic AI systems increasingly operate across critical infrastructure and defense sectors, closing with explicit caution that organizations should assume agentic AI systems may behave unexpectedly.
Every risk class in the Five Eyes guidance maps to specific MYTHOS Playbook chapters. Privilege risks map to Part II Architecture with patent-form least-privilege architecture. Design and configuration risks map to Part II and Part VI Deployment, plus Appendix G's 12-clause vendor RFP language library. Behavioral risks map to Part III Vectors with a seven-vector behavioral threat taxonomy and Part IV Frameworks with statistical detection methodology including HOTS Homology with 81.4% deception-detection precision. Structural risks map to Chapter 8's 8-2-8 compositional safety model and Part V SOC/Detection. Accountability risks map to Appendix F's GTID audit sample with hash-chained tamper-evidence and Chapter 31's NHI governance patterns.
The MYTHOS Playbook goes beyond the Five Eyes guidance by providing vendor RFP language in Appendix G, statistical detection methodology validated across 7,000 adversarial scenarios, a 119-cell framework cross-walk mapping to NIST AI RMF, OWASP LLM Top 10, OWASP Agentic Top 10, CRI FS AI RMF, and MITRE ATLAS, architectural patterns including a 5-layer governance pipeline, and hash-chained audit records aligned to SOX retention requirements.
Author Joseph P. Conroy, founder and CEO of VectorCertain LLC, said: "The Five Eyes did the hard policy work. The MYTHOS Playbook is the operational complement: the technical reference a CISO can hand to a security architect. We didn't write a book about the Five Eyes guidance—we wrote a book about the underlying threat landscape, and the Five Eyes published guidance arrived at the same risk taxonomy independently. That convergence is the strongest validation of both documents."
The manuscript was structurally complete before the Five Eyes guidance was published, with drafting starting in 2025. The Playbook's 7-vector behavioral risk taxonomy was independently derived from real-world incident analysis. When the Five Eyes guidance was published, its five risk classes mapped cleanly onto the Playbook's existing structural commitments. No retrofit was required.
The patent portfolio underlying the book's architectural commitments includes 55 patents in a hub-and-spoke structure across 7 verticals, with consolidated valuation ranging from $285M to $1.55B. The book is authored by Joseph P. Conroy, who has 30 years of experience building mission-critical AI systems, including the first commercial U.S. application using AI for parts-per-trillion gas detection in 1997.
SecureAgent, VectorCertain's AI Agent Security governance platform, has logged 14,208 internal trials across 38 techniques and 3 adversary profiles with zero failures, achieving a Technical Evaluation Score of 1.9636 out of 2.0 (98.2%) measured against MITRE's published TES methodology. The platform achieves a false-positive rate of 1 in 160,000—53,333× below the EDR industry average.
The MYTHOS Playbook: The CISO's Technical Guide to Governing Autonomous AI Agents is structured in 7 parts plus 9 appendices spanning ~450,000 words. Pre-order interest registration is open at vectorcertain.com.
