Enterprise e-commerce wanting chargeback guarantee (Forter / Signifyd / Riskified better), AML-primary fintech (ComplyAdvantage / Sardine better), or buyers who want one-vendor coverage across all surfaces (Sift better).
Product engineering teams at SaaS, fintech, and consumer companies (25-1,000 employees) who want developer-friendly fraud detection without a heavy enterprise sales motion.
Why we say this
Editorial pulled these weaknesses from Castle’s product card in our Top 10 Fraud Detection Software for 2026:
- ! Smaller installed base than Sift / Sardine
- ! E-commerce coverage shallower than Forter / Signifyd
- ! No chargeback guarantee model
- ! AML coverage absent
- ! Enterprise sales motion thinner than larger vendors
