However, it will present challenges for CIOs, in particular in maintaining security, she said. UCP as implemented by Google means retailers will be exposing REST (Representational State Transfer) endpoints to create, update, or complete checkout sessions. “That’s an additional attack surface beyond your web/app checkout. API gateways, WAF/bot mitigation, and rate limits become part of checkout security, not just a ‘nice-to-have’. This means that CIOs will have to implement new reference architectures and runtime controls; new privacy, consent, and contracts protocols; and new fraud stack component integration.”
Info-Tech Research Group principal research director Julie Geller also sees new security challenges ahead. “This is a major shift in posture. It pushes retail IT teams toward deliberate agent gateways, controlled interfaces where agent identity, permissions, and transaction scope are clearly defined. The security challenge isn’t the volume of bot traffic, but non-human actors executing high-value actions like checkout and payments. That requires a different way of thinking about security, shifting the focus away from simple bot detection toward authorization, policy enforcement, and visibility,” she said.
The introduction of UCP will undoubtedly mean smoother integration of AI into retail systems but, besides security challenges, there will be other issues for CIOs to grapple with.
