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 run incident response across hundreds of customer accounts. I led the redesign that unified capabilities from multiple tools into one multi-tenant system — restructuring the information architecture, designing role-based dashboards, and building a bulk rule-application pattern that let analysts act across hundreds of environments at once. The team handled 900–2,000 alarms per shift, so every interaction was designed for speed under pressure.
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.
The complete case study — problem breakdown, information-architecture work, the multi-tenant redesign, and high-fidelity screens — is protected under NDA.
