GTM-7SZV

This container ships 133 hand-written scripts (66 KB of JavaScript) to every visitor — more than 99% of the 46,522 containers we have measured. That is an application's worth of code, delivered as tag configuration.

What we observed

A real browser loaded sbisec.co.jp a month 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 10 hosts appeared only after consent was granted. Google recorded gcs=G111 (all granted).
Third parties contacted 25 hosts — sbisec.akamaized.net, cdn-edge.karte.io, cdn.robee.tech, ktid.karte-edge.io, cdn-issues.karte.io, static.karte.io, static.cloudflareinsights.com, mirror2.karte.io, and 17 more
dataLayer events seen gtm.js, sc_pv, gtm.dom

Where the data goes

Not observed — on the page we loaded, measurement went to Google and nowhere else. observed on sbisec.co.jp 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.

reviewdocument.write (6)
6 pieces of custom code call document.write.

Whydocument.write blocks the HTML parser while it runs, and browsers ignore it entirely once the page has finished parsing — so an async-loaded tag using it can silently do nothing.

CheckIf these tags fire on page load they are costing render time; if they fire later they may not be working at all. Worth confirming the tag still does what it was added to do.

Seenseen in 18.4% of 46,522 containers measured

reviewHardcoded http:// URL (5)
5 pieces of custom code reference a plain http:// address.

WhyOn an https:// page the browser blocks or upgrades these. Blocked means the tag quietly stops working; upgraded only works if that host also serves https.

CheckCheck whether the hosts below still respond over https, and update the URLs.

Seenseen in 12.8% of 46,522 containers measured

infoLoads JavaScript from another host (34)
34 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

infoVendor IDs written into custom code (4)
4 vendor IDs are pasted directly into custom HTML rather than held in a variable or template.

WhyChanging a property, pixel or account then means editing every tag that mentions it, and any one that gets missed keeps sending to the old destination indefinitely.

CheckFine if the ID never changes. If you have ever migrated a property, check that none of these still point at the old one.

Seenseen in 31.4% of 46,522 containers measured

infoUses browser storage (1)
1 piece 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.

Seenseen in 23.3% of 46,522 containers measured

infoConsent configuration detected (1)
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.

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.

Evidence of the exact bytes we read, not an identity: Google varies the response per request, so re-fetching an unchanged container yields a different checksum. Compare the published version instead.

Re-audit

This reading is from a month 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.
