When Purple is the right call
Purple is the stronger fit when WiFi itself is mission-critical, not just a marketing capture point. If you run multiple sites or operate internationally, need staff and multi-tenant WiFi alongside guest access, require secure roaming through Passpoint and OpenRoaming, or must satisfy enterprise procurement and compliance (ISO 27001, GDPR, CCPA, B Corp), Purple delivers WiFi, analytics, marketing automation and network access in one platform with transparent pricing and a free Connect tier.
When Adentro is the right call
Adentro is a genuine fit for US restaurants, retail and hospitality marketers whose primary goal is turning guest WiFi into a marketing and ad-attribution engine. Its named visit attribution and walk-through rate features are designed to connect online ad campaigns to in-store visits and on-premise sales, and its large US consumer-data network supports custom audience targeting. For a single-country marketing team focused on proving and amplifying local ad ROI, that focus is a strength.
