Common questions

Can I use Sardine or SEON on my phone?

No. Neither tool has a mobile app. Both are enterprise dashboards designed for desktop use by fraud analysts and compliance teams.

Which is easier to set up: Sardine or SEON?

SEON is much easier. It has a 14-day average implementation and a drag-and-drop workflow builder. Sardine requires dedicated engineering resources and custom integration.

Is Sardine better than SEON for stopping AI-generated fraud?

Yes, Sardine is stronger against AI-driven fraud because its agentic AI adapts in real-time and its True Piercing feature defeats location obfuscation. SEON is still good but relies more on static rules and signal scoring.

Which tool is cheaper for a small business?

Neither is cheap, but SEON is more likely to have a pricing tier a small business can afford. Sardine's custom pricing is designed for large enterprises processing billions.

Do these tools work with Shopify or other e-commerce platforms?

SEON has native integrations with Shopify and over 500 payment methods. Sardine is API-first and can integrate, but it's not as plug-and-play for e-commerce.

SEON wins for speed and ease of use; Sardine wins for deep AI automation against advanced fraud.

If you're a non-technical person or run a smaller business, start with SEON—it's faster to set up and easier to manage. If you have a dedicated engineering team and face sophisticated fraud at scale, Sardine's AI agents will save you more time in the long run.
