About
About this board
MDR Companies is an independent-of-vendors reference run by a small security consultancy, Decima Systems; no provider pays to appear.
What this is
A reference to 27 managed detection and response (MDR) and managed SOC providers, compared only on what they publish: which security tools they run on, what they do for you when something fires, the service levels and prices they state, and their own audits and certifications. Every fact links to the page it came from and carries the date it was checked. Where a provider doesn’t say, the board says “not stated”.
There are no star ratings, scores or reviews here, and no “best” list. The board is ordered by one rule you can check yourself, set out on the methodology page.
Who runs it, and how it is paid for
The consultancy named above sells no MDR or managed SOC service, and no provider on the board is ours. No provider pays to appear, to be placed, or to be described, and there are no affiliate links.
The site offers one thing: a free shortlist. If you send the shortlist form, we read it and reply by email with the providers on this board that fit what you told us. We only pass your details to a provider if you ask us to.

Email hello@mdrcompanies.com (subject “mdrcompanies.com”). If an entry about your company is wrong or out of date, send a link to the public page that shows the right fact; we correct entries from public sources only. How that works is on the methodology page.
