GDPR-compliant captive portal in an afternoon

A captive portal is the page guests see before they get online. Done right, it's the friendliest data-collection point you'll ever run, and a lawful one.

Steps

• Connect your access points to oneCDP (most captive-portal-capable hardware works).
• Brand the page: logo, colours, a short welcome, an optional promo.
• Pick a sign-in: email, SMS code or social login.
• Add an explicit consent checkbox stating what you collect and why.
• Publish. Visits start flowing into profiles immediately.

Conversion tips

Keep the ask small. One email field with clear consent beats a long form every time, and it gives you a clean basis to communicate later. Offer a reason to opt in: a small perk on the next visit works well.
