Risk Signals: A Practical Checklist for Targeted Human Review

Human review is valuable when it is targeted. It becomes a bottleneck when escalation is broad, subjective, or inconsistently applied. Risk signals create a repeatable way to route the right actions for review, while letting routine work proceed under defined controls.

What a risk signal is

A risk signal is a condition that increases the likelihood that an action requires review, additional evidence, or escalation. Signals are designed to be objective and repeatable so teams can operate them consistently.

Common risk signals teams use

Many teams start with 5 to 10 signals and refine over time. Common signals include:

Sensitive data present: regulated or confidential categories involved

External exposure: outputs sent outside the organization

Expanded scope: high-volume actions or broad permissions impact

Privilege level: elevated access or administrative actions

Policy ambiguity: unclear, conflicting, or missing rules

Novelty: unusual patterns compared to prior activity

Third-party involvement: connector or vendor permissions affect the action

Identity uncertainty: unclear ownership, delegation, or authorization

How teams use the checklist

Risk signals generally drive three outcomes:

Escalate for approval

Proceed with enhanced evidence

Block until the right condition is met

The checklist is most effective when each signal has a defined owner, a response-time expectation, and a standard for what must be recorded.
