Adaptive Authentication
Adaptive authentication dynamically adjusts authentication requirements based on contextual and behavioral risk signals.
Definition
Adaptive authentication is an authentication approach in which the required assurance level changes dynamically according to contextual risk signals. These signals may include device trust, geolocation anomalies, IP reputation, impossible travel, user behavior, time of access, application sensitivity, transaction value, or session history. Rather than applying the same control to every login, adaptive authentication adjusts friction and security requirements in real time.
Why it matters
Adaptive authentication helps balance security and usability by applying stronger controls only when the context justifies them.
The Ariovis perspective
Context improves an access decision only when the signals are reliable, understood and governed. Adding more signals does not automatically produce a better policy.
