Cross-Domain Consent: Sync Cookie Consent Across All Your Websites

Managing cookie consent across multiple domains means users get interrupted with repeated prompts — and your team juggles separate configurations for each site. Secure Privacy's cross-domain consent feature synchronizes consent once across all your linked domains, eliminating repeated banners and keeping you GDPR-compliant.

If your organization runs multiple websites or subdomains, you already know the problem: every domain shows its own cookie banner, users are interrupted with repeated consent prompts as they move between your sites, and your team is left managing separate configurations for each one. It's a frustrating experience for visitors — and a compliance headache for your team.

Most cookie consent solutions treat each domain in isolation. That means a user who accepts cookies on shop.example.com is asked again on help.example.com, and again on www.example.com. Patching this with manual cookie-sharing scripts is fragile, hard to audit, and unlikely to hold up under GDPR or CCPA scrutiny.

Cross-domain consent in Secure Privacy solves this at the platform level. It collects consent once and synchronizes it across all your linked domains automatically — no custom code, no repeated prompts, no compliance gaps.

By the end of this article you'll understand exactly how cross-domain consent works, who it's for, which plan includes it, and where to find the step-by-step setup guide.

Cross-domain consent is a cookie consent management feature that lets you collect and synchronize user consent across multiple domains or subdomains using a single, unified cookie banner. Instead of displaying a separate consent prompt on every website, Secure Privacy shares the user's consent decision across all your linked domains in real time — reducing friction and ensuring a seamless, GDPR-compliant experience as users navigate between your sites.

Cross-domain consent is available exclusively on the Secure Privacy Business plan and above. To enable the feature and configure it for your domains, follow the step-by-step setup guide: How to Enable Cross-Domain Consent in Secure Privacy.

Who Is This Feature For?

Cross-domain consent is designed for organizations that:

  • Operate multiple websites or subdomains under one brand (e.g. a main site, a shop, a support portal, and a blog)

  • Run multi-step user flows that span several domains — such as checkout or onboarding funnels

  • Need to centralize cookie consent management and reduce repeated prompts for returning users

  • Are required to demonstrate unified consent records for GDPR, CCPA, or ePrivacy compliance audits

If you manage only a single domain, standard Secure Privacy cookie consent covers your needs. Cross-domain consent is for multi-domain and multi-site setups where synchronization matters.

Common Questions and Troubleshooting
