demdex.net, measured on 189 sites
demdex.net is a hostname rather than a brand. Nobody puts it on a homepage, and most people meet it for the first time in a browser's network panel or a privacy report, with no obvious way to find out what it is. The name belongs to Adobe's audience-management infrastructure. It was contacted on 189 of the 5,294 sites in this index, 3.6% of them, making it the 21st most encountered company here. This index attaches no vendor label to it, but it does attach company: on 129 of those 189 sites, adobedtm.com was contacted during the same page load.
The hosts it travels with
adobedtm.com is present on 129 of the 189 sites, 68.3%. Then Google on 91 sites, everesttech.net on 85, OneTrust on 59, omtrdc.net on 43, go-mpulse.net on 32, Amazon Ads and akstat.io on 21 each, the Meta Pixel on 18 and hlx.page on 16. The distinguishing feature is the density at the top. Three of the five most frequent companions read as parts of one deployment rather than five independent decisions, and go-mpulse.net with akstat.io is a second pairing of the same kind. What the list describes is a stack that arrives together, not a scatter of separately chosen neighbours.
OneTrust on 79 of its sites
A recognised consent tool was present on 104 of the 189 sites, a little over half. OneTrust was seen on 79 of them, IAB TCF conformant tools on 20, Usercentrics on 3 and Osano on 2. One product dominates the group by a wide margin, and that matches the site list: OneTrust is the consent tool bought by organisations with procurement departments, and this is a population of large corporate estates rather than independent publishers.
Where it appears
The examples run from digicert.com at global rank 45 to mcafee.com at 502, and they cluster in a recognisable corner of the web: security and certificate vendors in digicert.com, avast.com, mcafee.com and paloaltonetworks.com, enterprise IT in ibm.com, developer infrastructure in mysql.com and docker.com, hosting in hostgator.com, a cable operator in comcast.net, and broadcast media in go.com, cnbc.com and foxnews.com. mcafee.com contacted 33 companies over its page load, the most of the twelve by a wide margin.
Early contact on 171 sites, with two clear extremes
On 171 of the 189 sites at least one company was contacted before the banner could be answered, a share of 90.5% that ranks 66th of the 88 companies here. The median count in that window is 7 and the median after the window closes is 2. The examples pull hard in both directions. hostgator.com recorded 15 of its 16 companies in the early window with first contact at 195 ms, and foxnews.com 15 of 17 at 358 ms. Against that, digicert.com recorded 5 companies with none early and a first outside request at 2,408 ms, and comcast.net 21 companies with just 1, first contact at 1,966 ms.
Eleven companies, but only one classified as tracking
The median site contacting demdex.net contacts 11 companies in total, 32nd of the 88 profiled here, and issues 50 requests, 34th. Its median count of tracker-classified companies is 1, which ranks 61st of 88, well down the table. That gap is the useful part: these are pages with a substantial third-party surface that a classifier reads as mostly benign infrastructure. Median first contact is 809 ms, 19th of 88 and comparatively late, with the quickest single first contact at 75 ms. MurmStack will run the same measurement against a site you choose and report every field on this page for it.

Questions
What is demdex.net?
A request host belonging to Adobe's audience-management infrastructure. It carries no vendor label in this index, so what is recorded about it is behavioural: it was contacted on 189 of 5,294 measured sites, and on 129 of those adobedtm.com was contacted too.
What does it mean if I see demdex.net in a network log?

Why does adobedtm.com show up alongside it so often?
The crawl records presence, not configuration. It found both hosts on 129 of the 189 sites, 68.3%, and everesttech.net on 85 and omtrdc.net on 43. It cannot tell you how those hosts were deployed or by whom.
