GTM-5H8VM8P

116 tags, 30 custom scripts, 9 third-party hosts — an ordinary container, near the middle of what we measure (median: 39 tags, 4 custom scripts).

30 custom HTML tags carrying 20 KB of JavaScript — more than 80% of the 46,522 containers we have measured. This runs on every page the container loads on.
9 third-party hosts reachable from its tags — more than 80% of the 46,522 containers we have measured.

What we observed

A real browser loaded globoplay.com.br 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 — Google

Measurement sent to google-analytics.com — Google

Consent Quantcast answered its own API. Nothing measured until it was granted — no analytics or advertising hit left the page beforehand, and 3 fired afterwards. That is the outcome consent is meant to produce. 10 hosts appeared only after consent was granted. Google recorded gcs=G111 (all granted).

Third parties contacted 25 hosts — s3.glbimg.com, ads-library.globo.com, www.gstatic.com, www.googletagmanager.com, connect.facebook.net, pixel.byspotify.com, analytics.tiktok.com, dynamic.criteo.com, and 17 more

Where the data goes

Not observed — on the page we loaded, measurement went to Google and nowhere else. observed on globoplay.com.br 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.

reviewWrites cookies directly (2)

2 pieces of custom code set cookies in code.

WhyCookies set this way bypass GTM's consent settings, because the consent checks live in the tag templates rather than in raw JavaScript.

CheckIf any of these cookies are used for analytics or advertising, confirm they are still gated on a consent decision.

Seenseen in 21.2% of 46,522 containers measured

reviewNo consent signal in the container (1)

Nothing in this container sets, reads, or gates on a consent state.

WhyThe container itself neither sets a Consent Mode default, holds any tag back for consent, nor references a known consent platform. Either enforcement lives entirely outside GTM — where it cannot be audited from here — or tags fire regardless of what a visitor chose.

CheckIf a consent platform blocks scripts before GTM loads, this is fine — confirm that is actually the case. If not, tags are firing on a choice nobody recorded.

Seenseen in 52.1% of 46,522 containers measured

infoLoads JavaScript from another host (10)

10 pieces 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.

Seenseen in 54.4% of 46,522 containers measured

infoUses browser storage (3)

3 pieces of custom code read or write localStorage or sessionStorage.

WhyBrowser storage persists across visits and is not covered by cookie consent tooling, so it is easy to overlook when auditing what you keep on a visitor's device.

CheckConfirm nothing personal is being kept there, and that it is covered by your privacy notice.

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.

What this audit describes

Containers change. These findings describe one specific artifact, and you can re-fetch it to check this reading.

Container	`GTM-5H8VM8P`
Published version	`225` — the identity of this configuration. It changes only when someone publishes.
Read at	2026-08-22 13:11:26 UTC (2 months ago)
Source	`https://www.googletagmanager.com/gtm.js?id=GTM-5H8VM8P`

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.
