Consent Enforcement is how we deliver Complete Quality – one of the three dimensions of complete data infrastructure.

​
The governance nightmare

You know this pain: Legal sets consent rules. Engineering implements them across five different scripts. Marketing adds a new tool – consent logic drifts. Then GDPR audits arrive and you discover half your tracking isn’t actually enforcing the rules Legal thought were in place. This is what happens when consent is an afterthought bolted onto client-side tracking. Each script maintains its own consent logic. Configuration drifts. Governance breaks. With server-first architecture, consent isn’t a complex add-on – it’s built into the foundation. The server validates consent for every event before any data reaches any destination. Compliance happens by design, not by hoping your team configured everything correctly.
Here’s what changes: Legal sets consent rules once in your Fidero project config. Engineering implements the pixel once. When Marketing adds new destinations, consent enforcement happens automatically server-side. When GDPR audits arrive, you show them server-side validation logs proving 95%+ enforcement consistency across all tools.The outcome: Legal gets compliance by design. Engineering eliminates 80% of tracking maintenance. Marketing tools keep working when consent rules change. Leadership sleeps soundly knowing governance is enforced universally before any data leaves.Target: 95% consent enforcement consistency across all destinations, automatically.

The messy edge case that breaks client-side implementations

Here’s the scenario that breaks traditional client-side consent: User clicks your Meta ad, lands on your site, browses three pages without accepting cookies. Then accepts analytics consent midway through their session. What breaks with client-side enforcement: First three pageviews are lost forever. Attribution context incomplete. Analytics tools show the user arriving on page 4 with no referrer. You can’t connect their conversion to the original Meta campaign. How Fidero handles this: The pixel safely queues events before consent is given. When the user accepts analytics consent, queued events replay automatically with complete attribution context preserved. Analytics tools see the full session from landing page through conversion, with Meta campaign context intact. Why this matters: No lost attribution data. Users who accept cookies mid-session still give you complete journey context. Your Meta campaigns optimise on actual conversion behaviour, not just users who immediately accept cookies.
One common mistake: teams implement consent on their marketing site but forget to enforce it for server-side events (webhooks, CRM integrations). With Fidero, the server validates consent for ALL events – whether they come from the browser, your backend, or third-party webhooks. Compliance is universal, not just client-side.
Google Consent Mode v2The pixel automatically captures and sends the required Google Consent Mode signals, ensuring your Google destinations remain compliant with EEA requirements. Zero deployment action from your team.PII minimisation by designOur entire architecture is built to minimise Personally Identifiable Information (PII) handled client-side. We don’t scrape forms, fingerprint browsers or store PII in cookies. Legal teams can trust architecture-level privacy protection, not just policy commitments.Cross-domain consent persistenceWhen users redirect from your marketing site to a checkout domain, the server maintains consent state across the boundary. Checkout domain inherits consent automatically – no re-prompting, no lost consent state, no broken tools.
