For web agencies across the EU
GDPR enforcement is no longer aimed only at large platforms. The violations that produced nine-figure fines in 2025 are technically identical to what runs on the small business sites your agency builds. You can be the one who finds them first.
GDPR enforcement across the EU
Thirty supervisory authorities now enforce the same regulation across the EEA, and the pace has changed sharply: most of the money ever fined under the GDPR has been imposed in the last three years.
In 2025 the French authority alone fined Google €325M and SHEIN €150M for cookies placed without valid consent.3 The Dutch authority fined Kruidvat €600,000 for pre-ticked boxes and issued formal warnings to more than 200 websites.4 Those two facts describe the same enforcement logic applied at two very different scales.
Most consent tools verify that a banner exists. Argus loads the site in a real browser, refuses consent as a user would, and records what still leaves for the network.
Consent Bypass Test
Argus clicks “Reject all”, then records every request that still leaves. This is the violation that cost Google €325M and SHEIN €150M in 2025, technically identical to what happens on ordinary client sites.
Server-side tracking
GTM Server-Side containers, Meta CAPI relays and CNAME-resolved subdomains that route data to third parties while appearing first-party to blockers.
Dark patterns in banners
Asymmetric buttons, extra clicks required to refuse, pre-ticked boxes. The Dutch DPA fined Kruidvat €600,000 for pre-ticked consent and warned over 200 websites.
Transfers outside the EEA
Session replay, analytics and advertising endpoints hosted outside the EEA, checked against the safeguards required by Chapter V of the GDPR.
Storage-based tracking
localStorage, sessionStorage and IndexedDB identifiers, which survive third-party cookie deprecation and are invisible to most consent tools.
Security headers
HSTS, CSP, X-Frame-Options and related headers, scored against OWASP recommendations and included in the same report.
Billed annually, no hidden subscription. A single audit resold at your own rate covers a large share of the yearly cost.
