AT&T All-In-One Service Architecture

While supporting the Public Sector team at AT&T Cybersecurity, we achieved strong success—particularly across the State of Texas and Oklahoma. To replicate this success at scale, we created a high-level architecture diagram that mapped how all cybersecurity products available through the AT&T Texas DIR contract could be integrated within a customer’s network environment.

When paired with the Managed Threat Detection and Response (MTDR) architecture, this visual aid became a powerful tool for sales teams. It enabled deeper technical conversations, uncovered upsell opportunities, and supported a land-and-expand growth strategy. Over three contract periods, this approach drove up to a 300% increase in cybersecurity spend per customer, while extending service engagements from 1–3 years to as long as 10 years, thanks to staggered deployments and the need for long-term service continuity.
