Adaptive RBA

Evaluates the user's login risk using an AI-based risk score and routes to Low, Medium, or High risk outputs based on configurable thresholds.

Category: Logic & Flow Nodes

Type: adaptive-rba

Typical position: After the Auth node's true output. Route Low directly to Success, Medium to a soft MFA step-up, and High to a hard block or strong MFA challenge.

Properties

Property	Type	Default	Description
Select Adaptive RBA	range slider	[20, 30]	Two threshold values on a 0–100 scale defining the Low/Medium and Medium/High boundaries. Scores below the lower threshold route to Low; scores between thresholds route to Medium; scores above the upper threshold route to High.

Outputs & Errors

Output	Condition
Low	AI risk score is below the lower threshold
Medium	AI risk score is between the lower and upper thresholds
High	AI risk score is above the upper threshold
false	Risk score could not be evaluated

Usage Notes

Adaptive RBA gives you three distinct risk lanes to apply proportionate step-up authentication. A common pattern is to let Low-risk logins proceed directly to the Success Final node, require SMS or TOTP MFA for Medium-risk logins, and trigger a stronger challenge (e.g. email OTP plus admin notification) or a hard block for High-risk logins. Calibrate the thresholds based on your tenant's risk tolerance and observed score distributions.
