Designing for Multi-Tenant Security Operations
"Tarica's knowledge of design thinking sets her apart from less experienced designers; while her clear presentation of reasoning inspires teammates and elevates those around her.”
— Matthew Oddo, Head of Design, AT&T
Overview
AT&T’s cybersecurity platform, AlienVault, is used by security analysts to monitor threats and manage incident response across complex environments. As the platform evolved, AT&T needed to unify capabilities from multiple systems into a single, cohesive experience—allowing analysts to work across hundreds of customer accounts without switching tools or losing context. I worked on redesigning the platform to support this shift, focusing on how to structure large-scale data, streamline workflows, and enable analysts to move more efficiently through high-volume, high-stakes investigations.
My Role
Led experience design across platform unification efforts — mapping existing workflows and identifying where the seams between systems created friction for analysts.
Conducted a product and IA audit to surface redundancies and contradictions across a platform that had grown through acquisition and rapid feature expansion.
Defined information architecture for multi-tenant workflows — the core structural problem that drove most downstream design decisions.
Designed interaction patterns for dashboards, filtering, and rule management, then created high-fidelity prototypes and documented system behaviors for engineering handoff.
