Walrus Security provides a B2B fintech platform that secures push payments through authentication technology. Its main product, DoubleCheck, helps financial-sector clients securely collect payment details for transactions involving wires and stock, aiming to reduce electronic impersonation fraud while keeping the process smooth for users. The company serves funds, fund administrators, fundraising platforms, and exchanges, and has processed over $6 billion in transaction volume, signaling trust and adoption in its niche. Unlike broader payment-security tools, Walrus Security concentrates on preventing impersonation fraud in payment details and frictionless collection for high-risk payment workflows. The goal is to minimize fraud risk and operational friction for institutions handling sensitive payment data.
