Financial API Threats We Stop

Card Testing Attacks

Attackers test stolen credit cards via rapid-fire payment API requests. We detect and block card testing patterns in real-time.

Prevention: Rate limiting per card BIN, velocity checks, behavior analysis

Account Takeover

Credential stuffing and brute force attacks against banking logins. We block suspicious authentication patterns before damage occurs.

Prevention: Login rate limiting, IP reputation, device fingerprinting

Transaction Manipulation

Parameter tampering to modify amounts, recipients, or currency. We validate all financial API payloads against tampering.

Prevention: Schema validation, parameter pollution detection, HMAC verification

Built for Financial Services
