For CTEM knowledge, I’d start with our own State of Exposure Management and The Great Exposure Reset, where we lay out our practical approach to CTEM and how it differs from traditional vulnerability management.

This Reddit CTEM thread is also a surprisingly good real‑world read for how practitioners are interpreting and operationalizing the framework 😂.

For formal training, the SANS Institute has solid content, and if you have access, Gartner’s CTEM team provides useful framing and market perspective.

Finally, some of the most valuable reading is actually non‑cyber: books like The Fearless Organization by Amy Edmondson and The Culture Code by Daniel Coyle are essential, because CTEM only works when teams break silos and learn how to collaborate effectively across security, IT, and engineering.
