What Does Sardine Offer?

Sardine offers a fraud prevention solution built using various third-party integrations and external data sources. Designed as a plug-and-play option for addressing foundational fraud challenges, it presents a streamlined setup on the surface. However, the underlying architecture incorporates multiple partner technologies, which may impact consistency across the platform.

Because it depends on several integrated systems, implementation can require more coordination, potentially leading to complex onboarding workflows and varied user experiences. Teams may need to work across multiple tools and data streams to manage fraud operations effectively.

For organizations with lighter fraud requirements, this model may still be sufficient. That said, working with multiple technologies can sometimes affect responsiveness, flexibility, and data freshness—especially in dynamic environments like fintech, iGaming, or e-commerce.

SEON offers an alternative with a fully in-house, unified solution—designed to minimize these challenges by delivering streamlined integration, direct access to real-time signals, and transparent, actionable insights from the start.

Why SEON Is the Leading Sardine Alternative

 If you’re exploring fraud prevention tools beyond Sardine, SEON stands out as a fully in-house solution purpose-built for real-time insights, faster onboarding, and seamless integration. Unlike Sardine’s white-labeled, multi-vendor approach, SEON delivers a direct-to-source, single-platform experience that ensures both speed and accuracy at every stage of the customer journey.
