Why digital sovereignty matters with VWO (Visual Website Optimizer)
VWO (Visual Website Optimizer) is headquartered in IN, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.
VWO (Visual Website Optimizer) hosts data in IN, US, EU. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.
VWO (Visual Website Optimizer) is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.
What this means for your organisation depends on your whole stack and context. The free assessment weighs VWO (Visual Website Optimizer) together with your other vendors and gives a total score, a heatmap and the main risk drivers.
