GDPR violations can result in fines up to €20 million or 4% of global annual turnover. Regulators across the EU have actively fined organizations for deploying tracking cookies without valid consent.
Check whether the site displays a cookie consent notice before setting non-essential cookies. Verify that analytics, advertising, and tracking scripts do not load until the user has actively accepted. Check whether users can reject non-essential cookies without losing access to content.
Implement a cookie consent management platform (CMP) that blocks non-essential scripts until consent is granted. Configure analytics and tracking tags to initialize only after explicit consent. Provide a mechanism for users to change their consent preferences at any time.
Explain what GDPR requires for cookie consent, the difference between essential and non-essential cookies, why pre-ticked boxes are invalid consent, and what a technically compliant consent implementation looks like.
Review server config, headers, forms, and integration points related to Show a cookie consent notice. Flag exact responses, cookies, or browser behaviors that violate the rule, and verify them against the effective production-like response. Check that tracker initialization is gated on consent and that a persistent "change cookie settings" path exists after the banner is gone.
