secupay

secupay is a BaFin-approved German payment institution, the largest owner-managed one in the country, founded in 2000. The platform handles transactions for approximately 15 million users across online shops, marketplaces, crowdfunding platforms, and point-of-sale businesses. That scale means the threat surface is broad: fraud, credential abuse, real-time transaction manipulation, and systemic risk across diverse payment flows.

The technical stack centers on electronic payments, cashless payments, and the hard problems embedded in them. The team operates across risk management, fraud prevention, and real-time scoring - domains where latency, false-positive rates, and adversarial adaptation are constant pressure. Payment methods span credit cards, PayPal, SEPA direct debit, purchase on account, and prepayment, each carrying distinct attack vectors and compliance requirements under German financial regulation.

secupay's product surface extends beyond pure payment processing into integrated fraud prevention tooling, eCommerce and POS terminal solutions, customer loyalty programs, and cashback systems for retailers. The security challenge isn't just perimeter defense - it's securing the data pipelines, scoring models, and transaction integrity across every vertical they serve, from crowdinvesting to token offerings. Geographic operations are currently Germany-based.
