container audit
GTM-M8KX2G
86 tags, 4 custom scripts, 5 third-party hosts — an ordinary container, near the middle of what we measure (median: 39 tags, 4 custom scripts).
- 4 custom HTML tags carrying 1 KB of JavaScript. This runs on every page the container loads on.
- 5 third-party hosts reachable from its tags.

What we observed
A real browser loaded hellmann.net 2 months ago and recorded every request it made. This is what happened, as distinct from what the container is configured to do. It is one page load — anything that fires only deeper in the site did not fire here.
Container loaded from
googletagmanager.com — GoogleMeasurement sent to
google-analytics.com — GoogleConsent
Cookiebot answered its own API. 2 measurement hits left the page before it was granted, carrying a client id (whether that is permitted depends on jurisdiction, and this was not a European visit). no new hosts appeared after granting — either the tags are ungated, or they fire regardless and record the decision. Google recorded
gcs=G111 (all granted). 7 advertising hosts were contacted before anything was granted.Third parties contacted
19 hosts — www.hellmann.com, consent.cookiebot.com, consentcdn.cookiebot.com, www.googletagmanager.com, snap.licdn.com, analytics.tiktok.com, bat.bing.com, www.clarity.ms, and 11 more

Where the data goes
Not observed — on the page we loaded, measurement went to Google and nowhere else. observed on hellmann.net More info »
Findings
Ordered by consequence. review has a concrete cost when it bites; info is real but depends on your setup. Seen is how common it is across the containers we have measured — reported separately on purpose, because common and harmless are different claims.
infoConsent configuration detected (3)
The container declares one or more consent signals.
WhyConsent handling is present in the container. This describes what the artifact declares; what actually happened on the page is measured separately, above.
CheckConfirm these settings match the consent policy you intend to enforce, and compare them with the before-and-after observation.

infoLoads JavaScript from another host (1)
1 piece of custom code fetch and run JavaScript from another host.
WhyWhatever that host serves executes with full access to the page — it can read the DOM, cookies and form fields. The code is not in this container, so it can change at any time without any change here.
CheckConfirm you recognise every host below and that someone owns the relationship. A host you cannot name is the one to chase.

Third parties it can reach
Each host is a party that can execute code or receive data in a visitor's browser. Follow one to see who else loads it. More info »

What the custom templates can do
Custom templates are third-party code shipped inside the container. Injecting scripts and running page globals is ordinary for them — most tag templates need it to work — so this is an inventory, not a warning. It lists the capability each template declares so you can match it against templates you meant to install.

Sites observed loading this container. A container used across many hosts is a shared template; one on a single host is a bespoke build. Follow a site to see every container it loads.

Re-audit
This reading is from 2 months ago. A container can be republished at any time, and nothing here updates on its own — a fresh read is the only way to know whether it still says this. Running it again replaces this page in place, so the link keeps working.
Put this container under version control. Tagora exports it to a repository you own, so every change arrives as a pull request. How it works »
