Risk-Based Authentication

❓ What is Risk-Based Authentication?

Risk-Based Authentication dynamically evaluates the risk level of each login attempt and adjusts authentication requirements accordingly — low risk gets frictionless access, high risk gets challenged.

⚙️ How Does It Work?

A risk engine scores signals: device fingerprint, IP reputation, geolocation, time of day, behavioral patterns, and threat intelligence. The score determines the response: allow, challenge, or block.

📍 Where Is It Used?

Banking apps, enterprise IAM, e-commerce fraud prevention, Zero Trust architectures.
