Zero Trust as a Journey: Lessons from General Robert Skinner

Zero Trust as a Journey: Lessons from General Robert Skinner

In this episode of Zero Trusts Given, host Tom Tittermary speaks with retired General Robert Skinner about the evolving role of Zero Trust across the Department of Defense. Drawing on decades of experience, Skinner emphasizes that Zero Trust is an ongoing journey—not a fixed endpoint—centered on resilience, identity, and continuous improvement against adversaries. The conversation explores key trends like the growing importance of identity, the balance between standardized solutions such as Thunderdome and flexible architectures, and the expanding role of AI in both cyber defense and attack. They also highlight persistent challenges around data visibility, logging, and cultural barriers, underscoring that achieving true Zero Trust requires both technological advancement and a shift in mindset across the organization.

Disconnected, Contested, and Secure: Zero Trust for the Tactical Edge

In episode thirteen of Zero Trusts Given, Tom Tittermary sits down with Dr. Mark Taylor, Chief Innovation Officer at Sage Creek USA and former CTO of U.S. Special Operations Command, for a deep dive into what Zero Trust really means for the Department of Defense. The conversation unpacks the evolution from network centric security models to data centric Zero Trust architectures, with a particular focus on mission partner access, cross domain solutions, and data tagging and policy enforcement. Dr. Taylor shares hard won insights on why traditional network boundaries and CDSs often undermine true Zero Trust, and how identity, ICAM, and policy based access controls are critical to enabling secure information sharing across classifications and nations. The episode also explores the stark contrast between enterprise and tactical environments—where disconnected, contested operations demand resilient, local decision making—and why commanders at the edge must retain authority to adapt security policies in real time. The result is a candid, practitioner level discussion on moving DoD Zero Trust from theory to mission impact, at the speed of need.

"Two Great Tastes That Taste Great Together," Zscaler & Vectra AI in the DoD

Episode twelve of the podcast, "Two Great Tastes That Taste Great Together," Zscaler & Vectra AI in the DoD, features Robert Marcoux, Federal Principal Technologist at Vectra AI, for a discussion on why traditional perimeter-based security no longer works in a world dominated by remote users, cloud services, and SaaS, and how Zero Trust has become essential. They explore how AI-driven signal analysis cuts through data noise, helping resource strained security teams detect threats faster and more accurately. The conversation also showcases how Vectra AI’s integration with Zscaler accelerates identity-centric detection and response, reducing MTTR by linking anomalous behavior directly to specific users and increasing visibility into attacks. Finally, the discussion emphasizes practical Zero Trust enforcement through a human in the loop model, combining AI-powered context with analyst oversight to maintain resilience across federal, defense, and critical infrastructure environments.

Identity as the Core of Zero Trust

Episode ten of the podcast, Identity as the Core of Zero Trust, features Dan Miller from Ping Identity, emphasizing that verifying digital identity and assessing user attributes in real time is critical before granting access to any DoD resource. He discusses the importance of using detailed attributes like location, device, and role instead of relying on simple logins to make smarter, real-time access decisions, which is crucial for secure operations in classified and remote environments. Since many DoD units work in disconnected settings, Ping Identity provides local identity solutions that keep missions running and sync with the cloud when reconnected. This episode explores how, in joint missions, enforcing secure data sharing through identity-driven access and tagging paves the way for granular Zero Trust.

These Guys Literally Wrote the Book

Episode nine of the podcast, These Guys Literally Wrote the Book, features Rob Freter and Joe Brinker from True Zero Technologies, delving into the evolving implementation of Zero Trust principles across the Department of Defense, the Defense Industrial Base, and the broader federal government. They discuss the importance of starting with a clear problem statement and solution, emphasizing the cultural and practical need for a structured approach to security, including policy enforcement points (PEPs). Drawing analogies to cinematic sequels like The Godfather Part II, the episode explores how Zero Trust architectures have evolved to be even better with their second iterations, offering cleaner lines and easier readability.
