Drift is measurable change in a Persona away from what TOTAL learned as normal for that identity and peer context. Drift insights prioritize slow, plausible shifts that simple rule sets often miss.

What is Drift

Drift compares current signal behavior to a baseline Persona built from historical observation. When values, relationships, or rhythms move beyond expected bounds, TOTAL surfaces drift highlights and detailed signal views so you can validate whether change is benign (new role, travel, tooling) or threat-related.

Drift Highlights

Drift Highlights show human-readable before / after summaries for the strongest deviations—often with attribute-level detail so you can see what changed without opening every chart.

Types of Drift

Collaboration Topology Shift

Changes in who the identity works with, how resources are shared, and how collaboration graphs evolve—surfaced as cards with before/after attributes when the model detects a structural shift.

Behavioral Pattern Shift

Broader changes in routine, tool usage, or work rhythm that do not map cleanly to a single category but still depart from the baseline (often visible across multiple signals in All Signals).

New Login Locations

Geographic or logical origin of authentication expands in ways that are new relative to baseline (for example, additional cities or regions appearing alongside prior anchors).

Auth Frequency Spike

Authentication or session-related activity accelerates compared to the learned cadence—useful for catching automation, shared credentials, or compromise-driven repetition. Other dimensions (sentiment, email patterns, passwordless metrics, peer Jaccard similarity, etc.) contribute to drift scoring as configured in your tenant.

Drift from Base Persona vs Drift from Cluster

TOTAL measures two related notions:
  • Drift from base Persona: deviation from this identity’s own historical profile.
  • Drift from Cluster: deviation from the like-cyber-minded cohort this Persona belongs to (see Clusters)
  • Drift from Cluster: deviation from the like-cyber-minded cohort this Persona belongs to (see Clusters)
Together they separate “this person changed” from “this person is diverging from peers who used to look similar,” which helps prioritize insider-style and slow-burn cases.

Collusion Detection

When two identities’ Personas drift in a similar or complementary direction, TOTAL can place them on a collusion watchlist. The intent is to catch coordinated behavior that may not spike on any single account in isolation. Related: Personas overview, Persona Signals, Clusters, Persona Directory
