VectorCertain LLC today announced the completion of manuscript-prep for The MYTHOS Playbook, a 34-chapter, 9-appendix technical reference designed to operationalize the new Five Eyes joint guidance on agentic AI security. The book, set for June 2026 publication, provides CISOs, security architects, and AI governance leads with direct mappings to every risk class identified in the May 1, 2026 guidance from CISA, NSA, and partner agencies across Australia, Canada, New Zealand, and the United Kingdom.
The Five Eyes guidance, titled "Careful Adoption of Agentic AI Services", identifies five risk classes: privilege, design and configuration, behavioral, structural, and accountability. VectorCertain's Playbook maps each class to specific chapters and appendices, offering architectural patterns, statistical detection methodology, vendor RFP language, and a 119-cell framework cross-walk.
Privilege risks are addressed in Part II's 5-layer governance pipeline, which includes patent-form least-privilege architecture. Design and configuration risks are covered in Part II and Part VI, alongside Appendix G's 12-clause RFP language library for procurement. Behavioral risks map to Part III's seven-vector threat taxonomy and Part IV's statistical detection methods, including HOTS Homology with 81.4% deception-detection precision. Structural risks are handled in Chapter 8's 8-2-8 compositional safety model and Appendix C's cross-walk to NIST AI RMF, OWASP frameworks, and MITRE ATLAS. Accountability risks are supported by Appendix F's hash-chained GTID audit record and Chapter 22's Crumpton 5/5 disclosure methodology.
The Playbook's detection methodology is built on 7,000 adversarial scenarios with 100% recall and a 3-sigma lower bound of ≥99.65% using the Clopper-Pearson exact binomial method. This statistical foundation, detailed in Appendix B, allows CISOs to apply the same mathematics to their own detection portfolios. The book also includes a complete vendor RFP language library at Appendix G, designed for direct insertion into critical-infrastructure procurement processes.
Joseph P. Conroy, founder and CEO of VectorCertain, emphasized that the Playbook's risk taxonomy was independently derived before the Five Eyes guidance was published. "The convergence between our 17-sprint risk taxonomy and the Five Eyes published taxonomy is independent confirmation that the threat landscape is exactly as severe as both documents describe," Conroy said. The company notes that one in eight enterprise breaches now involves AI agents, a 340% year-over-year surge, with 78% of compromised agents over-permissioned.
The Playbook is structured in seven parts, beginning with foundations on the threat landscape and statistical methodology, followed by architecture, threat vectors, detection frameworks, SOC operations, deployment, and appendices. The appendices include a 119-cell cross-reference matrix, a confusion matrix worksheet, and a glossary of 135 terms. Pre-order interest registration is open at vectorcertain.com.
VectorCertain's SecureAgent platform, which underpins the Playbook's architectural commitments, has logged 14,208 internal trials across 38 techniques with zero failures and a false-positive rate of 1 in 160,000. The platform's patent portfolio includes 55 patents valued between $285 million and $1.55 billion. Conroy's 30-year background includes developing the first commercial U.S. AI application for parts-per-trillion gas detection and building an AI-driven electricity futures trading company.
