This is the AT&T Managed Threat Detection and Response network architecture drawing. I put this drawing together in 2021 after working there since 2018. Before I drew this, the only way that any of the Sales Engineers had to demonstrate how the network architecture was laid out was with some cartoonish marketing-type graphics that did not tell the story. While we sold lots of the products with the old drawings, this drawing took our sales to a new level. This opened a conversation that we had yet to have and answered long and cumbersome questions without a descriptive drawing such as this one.
