Category Sourcing · MDR & XDR

MDR is not a commodity. Pick the one that fits your stack.

Six managed-detection-and-response providers in our curated catalog. They look similar on the glossy slides — they're not similar in practice. Below is the honest version: when each one wins, when each one loses, and how to source whichever fits without re-explaining your environment five times.

Side by side, without the marketing.
