3-D Secure (3DS)
3-D Secure (3DS) is an authentication protocol designed to enhance security for online card transactions by verifying the cardholder’s identity. Hellgate.io integrates 3DS flows through Guardian and Hub, supporting both 3DS 1 and 3DS 2 standards. Combined with delegated authentication and orchestration rules, this ensures compliance with PSD2 while maintaining a frictionless checkout experience.
