EU Launch Kit: SaaS Migration Case Study (GDPR + Hosting + Analytics)

October 6, 2025•By Visoniq TechCore

Project summary

Client: mid-market B2B SaaS (2500 active users)

Goal: Become EU-compliant for analytics & hosting, reduce latency in EU, and preserve product analytics.

Delivery window: 21 days

Result: EU-compliant analytics (Plausible + consent gating), EU-region hosting, and 18% LCP improvement.

Analytics: Replaced global GA4 tracking with a consent-gated GA4 setup + server-side event masking for EU visitors. Where required, we offered Plausible as an EU-hosted alternative.
Hosting: Migrated critical assets to an EU region (Vercel/Cloudflare Workers or DigitalOcean Frankfurt) and set cache rules for dynamic routes.
Cookie consent: Implemented an opt-in modal that blocks all marketing/analytics until acceptance. Consent logs retained for 12 months.
DPA & Subprocessors: Provided a DPA draft and an updated Subprocessor list (Cloudflare, Google Workspace, GA4).

Legal readiness: Client can sign EU contracts with confidence (DPA in place).
Performance: LCP improved by 18% in EU locations.
Retention: No functional impact to analytics when consent was provided - product funnels remain intact.

Don't remove analytics entirely - gate it. This preserves product insights and keeps marketing working after consent.
Use EU regions for backups & logging if your clients insist on EU data residency.
Document subprocessors publicly - clients ask for this first.
