AT&T

LevelBlue is AT&T's standalone cybersecurity business, providing managed security services and threat intelligence to enterprises worldwide. Its developer-facing tools—including APIs, integrations, and the Open Threat Exchange—equip teams to embed security into applications and workflows.

LevelBlue's previous documentation system wasn't keeping pace. Content was difficult to manage, navigation was clunky, and the overall developer experience felt outdated—lacking the responsiveness, interactivity, and polish today’s developers expect.

With Mintlify, LevelBlue refreshed its documentation with a modern, AI-native feel. An embedded AI assistant helps developers get answers instantly, while MCP servers integrate docs directly into developer workflows.

Beyond the end-user experience, Mintlify simplified internal collaboration with docs-as-code workflows, preview deployments, and a WYSIWYG editor that enables more contributors to contribute updates with confidence.

By moving to Mintlify, LevelBlue modernized both the way they build docs and the experience their end users, saving engineering time while delivering a faster, more responsive platform for their customers.
